Details:
- Modified the 0644 octal code used during installation of shared
libraries to 0755 (for Linux/OSX only). Thanks to Adam J. Stewart
for reporting this issue via #343.
- CREDITS file update.
Details:
- Changed the default installation prefix from $HOME/lib to /usr/local.
- Modified the way configure internally handles the prefix, libdir,
includedir, and sharedir (and also added an --exec-prefix option).
The defaults to these variables are set as follows:
prefix: /usr/local
exec_prefix: ${prefix}
libdir: ${exec_prefix}/lib
includedir: ${prefix}/include
sharedir: ${prefix}/share
The key change, aside from the addition of exec_prefix and its use to
define the default to libdir, is that the variables are substituted
into config.mk with quoting that delays evaluation, meaning the
substituted values may contain unevaluated references to other
variables (namely, ${prefix} and ${exec_prefix}). This more closely
follows GNU conventions, including those used by GNU autoconf, and
also allows make to override any one of the variables *after*
configure has already been run (e.g. during 'make install').
- Updates to build/config.mk.in pursuant to above changes.
- Updates to output of 'configure --help' pursuant to above changes.
- Updated docs/BuildSystem.md to reflect the new default installation
prefix, as well as mention EXECPREFIX and SHAREDIR.
- Changed the definitions of the UNINSTALL_OLD_* variables in the
top-level Makefile to use $(wildcard ...) instead of 'find'. This
was motivated by the new way of handling prefix and friends, which
leads to the 'find' command being run on /usr/local (by default),
which can take a while almost never yielding any benefit (since the
user will very rarely use the uninstall-old targets).
- Removed periods from the end of descriptive output statements (i.e.,
non-verbose output) since those statements often end with file or
directory paths, which get confusing to read when puctuated by a
period.
- Trival change to 'make showconfig' output.
- Removed my name from 'configure --help'. (Many have contributed to it
over the years.)
- In configure script, changed the default state of threading_model
variable from 'no' to 'off' to match that of debug_type, where there
are similarly more than two valid states. ('no' is still accepted
if given via the --enable-debug= option, though it will be
standardized to 'off' prior to config.mk being written out.)
- Minor variable name change in flatten-headers.py that was intended for
32812ff.
- CREDITS file update.
Details:
- Changed all occurrances of
micro-kernel -> microkernel
macro-kernel -> macrokernel
micro-panel -> micropanel
in all markdown documents in 'docs' directory. This change is being
made since we've reached the point in adoption and acceptance of
BLIS's insights where words such as "microkernel" are no longer new,
and therefore now merit being unhyphenated.
- Updated "Implementation Notes" sections of KernelsHowTo.md, which
still contained references to nonexistent cpp macros such as
BLIS_DEFAULT_MR_? and BLIS_PACKDIM_MR_?.
- Added 'run-fast' and 'check-fast' targets to testsuite/Makefile.
- Minor updates to Testsuite.md, including suggesting use of
'make check' and 'make check-fast' when running from the local
testsuite directory.
- Added a comment to top-level Makefile explaining the purpose behind
the TESTSUITE_WRAPPER variable, which at first glance appears to serve
no purpose.
Details:
- Removed explicit reference to The University of Texas at Austin in the
third clause of the license comment blocks of all relevant files and
replaced it with a more all-encompassing "copyright holder(s)".
- Removed duplicate words ("derived") from a few kernels' license
comment blocks.
- Homogenized license comment block in kernels/zen/3/bli_gemm_small.c
with format of all other comment blocks.
Details:
- Modified .travis.yml to automatically employ the simulation of
application-level threading within the testsuite, with supporting
changes to common.mk, the top-level Makefile, and
travis/do_testsuite.sh.
- Added a new pair of input files to testsuite directory with the
'.salt' suffix (similar to those with the '.fast' suffix) for
testing application-level threading.
- Updated docs/BuildSystem.md to document the new make targets
'testblis-salt' and 'checkblis-salt'.
Details:
- Modified .travis.yml to automatically test the mixed-datatype support
of the gemm operation, with supporting changes to common.mk, the
top-level Makefile, and travis/do_testsuite.sh.
- Added a new pair of input files to testsuite directory with the
'.mixed' suffix (similar to those with the '.fast' suffix) for testing
mixed-datatype gemm.
- Updated docs/BuildSystem.md to document the new make targets
'testblis-md' and 'checkblis-md'.
Details:
- Rewrote bli_winsys.c to define bli_setenv() and bli_sleep()
unconditionally, but differently for Windows and non-Windows, but
then disabled the definition of bli_setenv() entirely since BLIS
no longer needs to set environment variables. Updated bli_winsys.h
accordingly, and call bli_sleep() from within testsuite instead of
sleep() directly.
- Use
#if !defined(_POSIX_BARRIERS) || (_POSIX_BARRIERS != 200809L)
instead of
#if !defined(_POSIX_BARRIERS) || (_POSIX_BARRIERS < 0)
when guarding against local definition of pthread barrier in
testsuite. (The description for unistd.h implies that _POSIX_BARRIERS
should always be set to 200809L when barriers are supported, though I
won't be surprised if we encounter a case in the future where it is
set to something else such as 1 while still supported.)
- Removed old _VERS_CONF_INST definitions and installation rules in
top-level Makefile. These are no longer needed because we no longer
output libraries with the version and configuration name as
substrings.
- Comment/whitespace updates in Makefile, config.mk.in, common.mk,
configure, bli_extern_defs.h, and test_libblis.h.
- Added mention of 1m to README.md and other trivial tweaks.

Details:
- Use get-user-cflags-for() to generate cflags when compiling BLAS test
drivers and BLIS testsuite from top-level Makefile. Meant to include
these changes in previous commit (4b5437e). Thanks to Isuru Fernando
for pointing out this oversight.
Details:
- Updated the build system so that "lesser" Makefiles, such as those in
belonging to example code or the testsuite, may be run even if the
directory is orphaned from the original build tree. This allows a
user to configure, compile, and install BLIS, delete the build tree
(that is, the source distribution, or the build directory for out-
of-tree builds) and then compile example or testsuite code and link
against the installed copy of BLIS (provided the example or testsuite
directory was preserved or obtained from another source). The only
requirement is that make be invoked while setting the
BLIS_INSTALL_PATH variable to the same installation prefix used when
BLIS was configured. The easiest syntax is:
make BLIS_INSTALL_PATH=/install/prefix
though it's also permissible to set BLIS_INSTALL_PATH as an
environment variable prior to running 'make'.
- Updated all lesser Makefiles to implement the new aforementioned build
behavior.
- Relocated check-blastest.sh and check-blistest.sh from build to
blastest and testsuite, respectively, so that if those directories are
copied elsewhere the user can still run 'make check' locally.
- Updated docs/Testsuite.md with language that mentions this new option
of building/linking against an installed copy of BLIS.
Details:
- Changed the cleanmk target to delete makefile fragments from their new
home in obj/$(CONFIG_NAME). The old definition worked only because of
a typo (REFERKN_PATH instead of REFKERN_PATH), and only in the
non-verbose (V != 1) case.
Details:
- Redefined the 'test' make target in the top-level Makefile so that the
final result ("everything passed" or at "least one failure") is echoed
to stdout. Note that 'check' is unchanged, and thus is now effectively
a fast version of 'test'.
- Updated docs/BuildSystem.md to reflect the above change.
Details:
- Fixed a linker error that occurred when attempting to compile and link
the testsuite and/or BLAS test drivers after having configured BLIS to
only generate a shared library (no static library). The chosen
solution involved
(1) adding the local library path, $(BASE_LIB_PATH), to the search
paths for the shared library via the link option
-Wl,-rpath,$(BASE_LIB_PATH).
(2) adding a local symlink to $(BASE_LIB_PATH) that uses the .so major
version number so that ld would find the shared library at
execution time.
Thanks to Sajid Ali for reporting this issue, to Devin Matthews for
pointing out the need for the -rpath option, and to Devangi Parikh for
helping Sajid isolate the problem.
- Added #include <ctype.h> to bli_system.h to avoid a compiler warning
resulting from using toupper() from bli_string.c without a prototype.
Thanks again to Sajid Ali, whose build log revealed this compiler
warning.
- Added '*.so.*' to .gitignore.
- CREDITS file update.
Details:
- Added support for --enable-arg-max-hack to configure, which will
change the behavior of make when building BLIS so that rather than
invoke the archiver/linker with all of the object files as command
line arguments, those object files are echoed to a temporary file
and then the archiver/linker is fed that temporary file via the @
notation. An example of this can be found in the GNU make docs at
https://www.gnu.org/software/make/manual/make.html#File-Function
- Thanks to Isuru Fernando for prompting this feature.
Details:
- Added a c99 sandbox (in sandbox/c99) to serve as a starting point for
others looking to experiment with alternative implementations of gemm
in BLIS. Note that this sandbox implementation is a first draft and
will be refined over time.
- Minor updates to Makefile and common.mk to restrict what source files
get recompiled when sandbox files are touched.
- Added an initial draft of a README.md in sandbox/c99.
Detail:
- configure:
- add support for --enable-sandbox=NAME to configure script, where NAME
is a subdirectory of a new 'sandbox' directory that contains an
alternative implementation of gemm. (For now, only implementations of
gemm may be provided via a sandbox.);
- add support for C++ compiler. C++ compilers are handled in a manner
similar to that of C compilers, in that a default search order is
used, and that CXX is searched for first, if the variable is set. In
practice, the C++ compiler that is selected should correspond to the
selected C compiler. (Example: If gcc is selected for C, g++ should
be selected for C++.) The result of the search is output to config.mk
via build/config.mk.in. NOTE: The use of C++ in BLIS is still
hypothetical, but may eventually move to being experimental. This
support was intended only for use of C++ within a gemm sandbox.
- build/config.mk.in:
- define SANDBOX variable containing sandbox subdirectory name.
- build/bli_config.in:
- define either of the BLIS_ENABLE_SANDBOX or BLIS_DISABLE_SANDBOX
macros in bli_config.h.
- common.mk:
- include makefile fragments that were propagated into the specified
sandbox subdirectory;
- generate different CFLAGS for sandboxes, as well as a separate
CXXFLAGS variable for sandboxes when C++ source files are compiled;
- isolate into a single location lists of file suffixes for various
purposes.
- reorganized/clean up code related to identifying header files and
paths.
- Makefile:
- generate object filepaths for and compile source code files found in
sandbox sub-directory;
- remove makefile fragments placed in sandbox sub-directory (cleanmk);
- various other cleanups.
- Added .cc, .cpp, and .cxx to list of suffixes of files to recognize in
makefile fragments (via build/gen-make-frags/suffix_list).
- Updated blis.h to conditionally #include bli_sandbox.h (via a new file,
bli_sbox.h), which each sandbox is assumed to use for any type
definitions and function prototypes it wishes to export out to blis.h.
- Conditionally disable bli_gemmnat() implementation in frame/3 when
BLIS_ENABLE_SANDBOX is defined.
* Fix detection of systems other than Linux and macOS
The way the logic is currently laid out, any platform that isn't Linux
gets assigned the .dylib shared library extension and the macOS-specific
compiler flags. This reverses the logic to check for macOS first, and
have the fallback use the Linux definitions, which apply to most other
systems as well.
* Use SHLIB_EXT instead of SO_SUF
The former is more standard, as jakirkham pointed out in a comment.
Details:
- Use the .dylib shared library suffix on OS X (instead of .so in Linux).
- Link with the -dynamiclib and -install_name options on OS X (instead of
-shared and -soname in Linux).
- Determine operating system (e.g. Linux, Darwin) during configure and
substitute into config.mk.in rather than run 'uname -s' during make.
- Echo operating system during configure.
Details:
- Tweaked configure so that the shared library is generated by default.
- Updated --help text and configure's feedback messages reporting the
status of the static/shared builds.
- Changed the order of build product installation so that headers are
installed last, after libraries and symlinks.
Details:
- Changed the naming conventions used for installed libraries and
symlinks to more closely mirror patterns used by typical GNU/Linux
libraries. Whereas previously static and shared libraries were
installed and symlinked as follows:
(library) libblis-0.3.2-15-haswell.a
(library) libblis-0.3.2-15-haswell.so
(symlink) libblis.a -> libblis-0.3.2-15-haswell.a
(symlink) libblis.so -> libblis-0.3.2-15-haswell.so
we now use the following naming conventions:
(library) libblis.a
(symlink) libblis.so -> libblis.so.0.1.2
(symlink) libblis.so.0 -> libblis.so.0.1.2
(library) libblis.so.0.1.2
where 0.1.2 indicates shared library major, minor, and build versions
of 0, 1, and 2, respectively. The conventional version string can
still be queried by linking to the library in question and then calling
bli_info_get_version_str(). (The testsuite binary does this
automatically at startup.)
- Added logic to common.mk to set the soname field in the shared library
via the -soname linker flag.
- Added a 'so_version' file to the top-level directory containing two
lines. The first line specifies the .so major version number, and the
second line specifies the minor and build version numbers joined with
a '.'. This file is read by configure and those values substituted
into build/config.mk.in to define SO_MAJOR, SO_MINORB, and SO_MMB
variables.
Details:
- Renamed the following variables in config.mk (via build/config.mk.in):
BLIS_ENABLE_VERBOSE_MAKE_OUTPUT -> ENABLE_VERBOSE
BLIS_ENABLE_STATIC_BUILD -> MK_ENABLE_STATIC
BLIS_ENABLE_SHARED_BUILD -> MK_ENABLE_SHARED
BLIS_ENABLE_BLAS2BLIS -> MK_ENABLE_BLAS
BLIS_ENABLE_CBLAS -> MK_ENABLE_CBLAS
BLIS_ENABLE_MEMKIND -> MK_ENABLE_MEMKIND
and also renamed all uses of these variables in makefiles and makefile
fragments. Notice that we use the "MK_" prefix so that those variables
can be easily differentiated (such as via grep) from their "BLIS_" C
preprocessor macro counterparts.
- Other whitespace changes to build/config.mk.in.
- Renamed the following C preprocessor macros in bli_config.h (via
build/bli_config.h.in):
BLIS_ENABLE_BLAS2BLIS -> BLIS_ENABLE_BLAS
BLIS_DISABLE_BLAS2BLIS -> BLIS_DISABLE_BLAS
BLIS_BLAS2BLIS_INT_TYPE_SIZE -> BLIS_BLAS_INT_TYPE_SIZE
and also renamed all relevant uses of these macros in BLIS source
files.
- Renamed "blas2blis" variable occurrences in configure to "blas", as
was done in build/config.mk.in and build/bli_config.h.in.
- Renamed the following functions in frame/base/bli_info.c:
bli_info_get_enable_blas2blis() -> bli_info_get_enable_blas()
bli_info_get_blas2blis_int_type_size()
-> bli_info_get_blas_int_type_size()
- Remove bli_config.h during 'make cleanh' target of top-level Makefile.
Details:
- Added support for two new configure options: --libdir and --includedir.
They specify the precise install directories for libraries and header
files, respectively, and override any location implied by the --prefix
option (including the default install prefix, if --prefix was not
given). Thanks to Nico Schlömer for suggesting this via issue #195.
- Removed the INSTALL_PREFIX definition/anchor from build/config.mk.in
and replaced it with corresponding definitions/anchors for libdir and
includedir.
- Updated top-level Makefile to use the new variables, INSTALL_LIBDIR
and INSTALL_INCDIR, instead of INSTALL_PREFIX (which is now no longer
needed by make).
- Set default sane values for INSTALL_LIBDIR and INSTALL_INCDIR in
common.mk when configure has not been run, as is already done for
DIST_PATH. This is to safeguard against statements in the top-level
Makefile that use 'find' to locate old libraries and headers for the
uninstall targets, which run regardless of make target. Without setting
INSTALL_LIBDIR and INSTALL_INCDIR, those variables are empty and the
'find' ends up looking at '/', which is obviously not what we want.
(Also enclosed those definitions in an IS_CONFIGURED guard so that they
won't get evaluated unless configure has been run.)
- Rearranged "ifeq ($(IS_CONFIGURED),yes)" conditionals in Makefile to
reduce occurrences and separated "local" and top-level components of
cleanblastest and cleanblistest targets to improve readability.
- Adjusted out-of-tree builds so that they are no longer oblivious to
the .git directories, if present, and thus now properly augment version
strings with the appropriate patch number.
- Include missing version string in 'configure --help' output.
Details:
- Modified top-level Makefile so that a user can run 'make distclean',
'make clean', or any of the other clean-related targets prior to
running configure (or after a previous 'make distclean'). Thanks to
Nico Schlömer for suggesting this via issue #197.
- Made the cleanblastest and cleanblistest more comprehensive in that
they now clean out build products that would have resulted from local
compilation (ie: builds performed within the 'blastest' or 'testsuite'
directories).
- Added "cc" to list of expected compiler "vendors" since the CC variable
seems to automatically be set to "cc" on Ubuntu 16.04 (which is just an
alias to gcc).
- Comment update to build/config.mk.in.
Details:
- Execute 'cleanh' target as part of 'clean'
- Remove cblas.h file from 'include/<configname>/' as part of 'cleanh'
target.
- Updated the echoed (non-verbose) text for uniformity.
Details:
- Imported the 24x16 knl sgemm microkernel (and its corresonding spackm
kernel) from TBLIS and enabled its use in the knl sub-config. Also
Added sgemm microkernel prototype to bli_kernels_knl.h.
- Updated dgemm and dpackm microkernels from TBLIS, which included an
important change regarding the offsets array (changed from extern
declaration to static declaration/definition).
- Activated use of level-1v and -1f zen kernels in skx and knl
sub-configs.
- Removed some old macros no longer needed in bli_family_skx.h now that
libmemkind support exists in configure.
- Moved bli_avx512_macros.h to frame/include and adjusted #includes in
skx and knl kernels accordingly.
- Moved unused kernels in kernels/knl/3 to kernels/knl/3/other
directory.
- Fixed a minor bug in the 'make' output per compile when verboseness
is not turned on. The rule-generating function 'make-kernel-rule' was
previously passing in the name of the config, rather than the name of
the kernel set returned by get-config-for-kset, which could give
misleading information to the user when the kconfig_map mapped a
kernel set to a sub-configuration that did not share the same name.
(This didn't affect the CFLAGS that were actually used.)
- Updated test/3m4m/Makefile, removing acml targets and renaming the
remaining targets.
Details:
- Updated the build system and BLAS test drivers to use 64-bit integers
when BLIS is configured for 64-bit integers in the BLAS layer. Also
updated blastest/Makefile accordingly. Thanks to Dave Love for
reporting the need for this feature.
- Added a 'check' target to blastest/Makefile so that the user can see
a summary of the tests.
- Commented out the initial definition of INCLUDE_PATHS in common.mk,
which was used pre-monolithic header, back when BLIS needed paths to
*all* headers, rather than just a select few. This line is no longer
needed since the value of INCLUDE_PATHS is overwritten by a later
definition limited to only the header paths that are needed now.
Details:
- Removed CKOPTFLAGS and CVECFLAGS from the set of CFLAGS used to
compile bli_cntx_ref.c for each configuration. This is necessary
because the file defines functions like bli_cntx_init_skx_ref(),
which are called during BLIS's initialization of the global kernel
structure, potentially being executed by an architecture that lacks
the instruction set used to compile the kernels for, in this example,
skx, which would lead to an illegal instruction error. Thanks to
Dave Love for reporting this issue.
- Further adjusted CFLAGS used when compiling code in the 'config'
directory (e.g. bli_cntx_init_skx.c) as well as code in 'frame' so
as to avoid the aforementioned issue.
Details:
- Added color coding to output of check-blistest.sh, check-blastest.sh
scripts. Success messages are coded green and failure are coded red.
This helps draw the eye toward those messages as the 'make checkblis',
'make checkblis-fast', and 'make checkblas' targets are executed.
- Changed top-level Makefile so that execution will not halt if
'checkblis', 'checkblis-fast', or 'checkblas' targets fail, which
means that the second of the two tests (BLIS and BLAS) run by
'make check' will run even if the first test fails.
Details:
- Added logic to common.mk that will choose a BLIS library against which
to link (LIBBLIS_LINK). The default choice is the static (.a) library;
the shared (.so) library is chosen only if the shared library build was
enabled and the static one was disabled.
- Updated the various test driver Makefiles to reference this common,
pre-chosen library against which to link. (Previously, these drivers
unconditionally linked against the static library and would have
failed if the static library build was disabled at configure-time.)
- Renamed many of the variables in common.mk and the top-level Makefile
so that variables relating to the libblis.[a|so] files, including
paths to those files, begin with "LIBBLIS".
- Shuffled around some of the library definitions from the top-level
Makefile to common.mk.
- Renamed BLIS_ENABLE_DYNAMIC_BUILD to BLIS_ENABLE_SHARED_BUILD, and
the @enable_dynamic@ anchor to @enable_shared@ in build/config.mk.in
and in configure.
- A few other cleanups in the top-level Makefile.
Details:
- Added an 'input.operations.fast' file to testsuite directory to go
along with the 'input.general.fast' file used by the 'make check'
target in the top-level Makefile. This will allow the "fast" check
to prune operations and/or parameter combinations from the test
space in order to save time.
- Currently, input.operations.fast prunes trmm3 and all transposition
and conjugation parameters from the level-3 test space.
- Reduced problem size tested in input.general.fast to 100 and disabled
testing of 1m method.
Details:
- Created a new test suite that exercises only the BLAS compatibility
found in BLIS. The test suite is a straightforward port of code
obtained from netlib LAPACK, run through f2c and linked to a stripped-
down version of libf2c that is compiled along with the test drivers
(to prevent any obvious ABI issues). The new BLAS test suite can be
run from within its new local directory, 'blastest' (through its local
'make ; make run' targets) or from the top-level Makefile (via the
'make testblas' target). Output files are created in whatever directory
the test drivers are run, whether it be the 'blastest' directory, the
top-level source distribution directory, or the out-of-tree directory
in which 'configure' was run. Also, the results of the BLAS test suite
can be checked via 'make checkblas', which summarizes the presence or
absence of test failures in a single line printed to stdout.
- Updated the 'test' target to run both 'testblis' and 'testblas'.
- Added a new 'testblis-fast' target that runs the BLIS testsuite with
smaller problem sizes, allowing it to finish more quickly.
- Added a 'make check' target, which runs 'checkblis-fast' and
'checkblas'.
- Changed .travis.yml so that Travis CI runs 'testblis-fast' instead of
'testblis' before (calling the check-blistest.sh script to check the
result manually).
- Renamed some targets in the top-level Makefile to be consistent between
BLAS and BLIS.
Details:
- Reorganized linker-related section of common.mk so that LDFLAGS set
in a sub-configuration's make_defs.mk file will not be immediately
(and erroneously) overridden by the default values.
- Re-enabled redirected (to file) output of the testsuite when run from
the top-level Makefile via 'make test'. (For some reason, it was
commented-out for the non-verbose case.)
- Removed old/unnecessary code from the make_defs.mk files of skx and
knl sub-configurations.
Details:
- Rewrote code that selects the compiler for the purposes of compiling
the auto-detection executable. CC (if specified) is tried first. Then
gcc. Then clang. The absolute fallback is cc. The previous code was
sort of broken, and seemed to unintentionally always use gcc.
- Moved various configuration-agnostic flags from config/*/make_defs.mk
files to common.mk. The new mechanism appends the configuration-
agnostic flags to the various compiler flag variables initialized in
make_defs.mk. Flags specific to the sub-configuration are still set
in make_defs.mk.
- Added -Wno-tautological-compare to CMISCFLAGS when clang is in use.
Also added the flag to the compiler instantiation during configure-
time hardware detection (when clang is selected).
- Added some missing (but mostly-optional) quotes to configure script.
Details:
- Added "temp_dir" argument to flatten-headers.sh so that the caller can
specify where intermediate files should be created as the script runs.
- Updated flatten-headers.sh to create intermediate files in temp_dir
instead of alongside the corresponding source files. This should now
(once again) allow out-of-tree builds where the BLIS distribution is
read-only, or where the out-of-tree build is running concurrently with
another out-of-tree build. (Thanks to Devin Matthews for pointing out
the possibility of simultaneous out-of-tree builds.)
Details:
- Defined a new 'uninstall-old-headers' target that allows users of BLIS to
uninstall no-longer-needed headers left over from previous installations.
- Fixed the 'uninstall-old' target so that it will install both .a and .so
libraries.
- Renamed 'uninstall-old' to 'uninstall-old-libs'.
- Added 'uninstall-old' target (different from previous 'uninstall-old'
target) that combines 'uninstall-old-libs' and 'uninstall-old-headers'.
Details:
- When CBLAS is enabled at configure-time, BLIS now creates a monolithic
cblas.h using the same flatten-header.sh script that was recently
introduced for creating monolithic blis.h header files. The top-level
Makefile will also install this cblas.h file into the install prefix
alongside blis.h when the 'install' target is invoked. The two header
files are compatible with one another. Regardless whether the user's
source #includes cblas.h, both blis.h and cblas.h, or just blis.h,
the user will get the CBLAS function prototypes and enums, as expected.
Details:
- Rewrote monolithify-header.sh (and renamed to flatten-header.sh) so that
headers are inserted recursively. This improves performance by a factor
of 3-4x.
- Modified configure to create an 'include/<configname>' directory in which
make can create a monolithic header.
- Modified the top-level Makefile so that a monolithic header is generated
unconditionally prior to compilation (stored in include/<configname>) and
so that the single header is installed instead of the 450 or so header
files that reside throughout the framework source tree.
- Added "include/*/*.h" to .gitignore file.
- Removed some pnacl/emscripten leftovers that I intended to include in
a1caeba (mostly in testsuite/Makefile).
- Trivial comment changes to frame/include/bli_f2c.h.
Details:
- Fixed incorrect calling sequence in bli_cntx_init_knl.c--an instance of
bli_blksz_init_easy() that should have been bli_blksz_init().
- Fixed a bug in code that is supposed to output the list of sub-directories
in the 'config' directory when configure script is run with no arguments.
- Expanded the output of "make showconfig" to include more info from config.mk.
- Minor changes to build/auto-detect/cpuid_x86.c, mostly in preparation for
someone to add excavator and zen support.
- Added a link to the ConfigurationHowTo wiki to config_registry.
- Other minor tweaks to configure.
Details:
- Added a "generic" configuration that leaves the default blocksizes and
kernels unchanged. This replaces the older "reference" configuration.
Updated auto-detect script and code accordingly.
- Added support for generic configuration to arch_t (bli_type_defs.h),
bli_gks_init() (bli_gks.c), and bli_arch_config.h
- Moved bli_arch_query_id() to bli_arch.c (and prototype to bli_arch.h).
- Whitespace changes to configurations' make_defs.mk files.
Details:
- Updated the top-level Makefile's build rule for testsuite object files to
properly obtain CFLAGS via get-frame-cflags-for() function instead of
simply using the $(CFLAGS) variable (which is empty). This means that
'make test' should now work as expected.
Details:
- Fixed semi-broken testsuite Makefile and very-broken test driver Makefiles,
as well as those for test/3m4m, test/thread_ranges, and test/exec_sizes
sub-directories.
- Factored out much of the top-level Makefile into common.mk. A Makefile
needs only set DIST_PATH to the relative path to the top level of the
BLIS source distribution before including common.mk in order to acquire
all of the definitions typically needed in a Makefile that tests BLIS.
