* 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.
Details:
- Reworked the build system around a configuration registry file, named
config_registry', that identifies valid configuration targets, their
constituent sub-configurations, and the kernel sets that are needed by
those sub-configurations. The build system now facilitates the building
of a single library that can contains kernels and cache/register
blocksizes for multiple configurations (microarchitectures). Reference
kernels are also built on a per-configuration basis.
- Updated the Makefile to use new variables set by configure via the
config.mk.in template, such as CONFIG_LIST, KERNEL_LIST, and KCONFIG_MAP,
in determining which sub-configurations (CONFIG_LIST) and kernel sets
(KERNEL_LIST) are included in the library, and which make_defs.mk files'
CFLAGS (KCONFIG_MAP) are used when compiling kernels.
- Reorganized 'kernels' directory into a "flat" structure. Renamed kernel
functions into a standard format that includes the kernel set name
(e.g. 'haswell'). Created a "bli_kernels_<kernelset>.h" file in each
kernels sub-directory. These files exist to provide prototypes for the
kernels present in those directories.
- Reorganized reference kernels into a top-level 'ref_kernels' directory.
This directory includes a new source file, bli_cntx_ref.c (compiled on
a per-configuration basis), that defines the code needed to initialize
a reference context and a context for induced methods for the
microarchitecture in question.
- Rewrote make_defs.mk files in each configuration so that the compiler
variables (e.g. CFLAGS) are "stored" (renamed) on a per-configuration
basis.
- Modified bli_config.h.in template so that bli_config.h is generated with
#defines for the config (family) name, the sub-configurations that are
associated with the family, and the kernel sets needed by those
sub-configurations.
- Deprecated all kernel-related information in bli_kernel.h and transferred
what remains to new header files named "bli_arch_<configname>.h", which
are conditionally #included from a new header bli_arch.h. These files
are still needed to set library-wide parameters such as custom
malloc()/free() functions or SIMD alignment values.
- Added bli_cntx_init_<configname>.c files to each configuration directory.
The files contain a function, named the same as the file, that initializes
a "native" context for a particular configuration (microarchitecture). The
idea is that optimized kernels, if available, will be initialized into
these contexts. Other fields will retain pointers to reference functions,
which will be compiled on a per-configuration basis. These bli_cntx_init_*()
functions will be called during the initialization of the global kernel
structure. They are thought of as initializing for "native" execution, but
they also form the basis for contexts that use induced methods. These
functions are prototyped, along with their _ref() and _ind() brethren, by
prototype-generating macros in bli_arch.h.
- Added a new typedef enum in bli_type_defs.h to define an arch_t, which
identifies the various sub-configurations.
- Redesigned the global kernel structure (gks) around a 2D array of cntx_t
structures (pointers to cntx_t, actually). The first dimension is indexed
over arch_t and the inner dimension is the ind_t (induced method) for
each microarchitecture. When a microarchitecture (configuration) is
"registered" at init-time, the inner array for that configuration in the
2D array is initialized (and allocated, if it hasn't been already). The
cntx_t slot for BLIS_NAT is initialized immediately and those for other
induced method types are initialized and cached on-demand, as needed. At
cntx_t registration, we also store function pointers to cntx_init functions
that will initialize (a) "reference" contexts and (b) contexts for use with
induced methods. We don't cache the full contexts for reference contexts
since they are rarely needed. The functions that initialize these two kinds
of contexts are generated automatically for each targeted sub-configuration
from cpp-templatized code at compile-time. Induced method contexts that
need "stage" adjustments can still obtain them via functions in
bli_cntx_ind_stage.c.
- Added new functions and functionality to bli_cntx.c, such as for setting
the level-1f, level-1v, and packm kernels, and for converting a native
context into one for executing an induced method.
- Moved the checking of register/cache blocksize consistency from being cpp
macros in bli_kernel_macro_defs.h to being runtime checks defined in
bli_check.c and called from bli_gks_register_cntx() at the time that the
global kernel structure's internal context is initialized for a given
microarchitecture/configuration.
- Deprecated all of the old per-operation bli_*_cntx.c files and removed
the previous operation-level cntx_t_init()/_finalize() invocations.
Instead, we now query the gks for a suitable context, usually via
bli_gks_query_cntx().
- Deprecated support for the 3m2 and 3m3 induced methods. (They required
hackery that I was no longer willing to support.)
- Consolidated the 1e and 1r packm kernels for any given register blocksize
into a single kernel that will branch on the schema and support packing
to both formats.
- Added the cntx_t* argument to all packm kernel signatures.
- Deprecated the local function pointer array in all bli_packm_cxk*.c files
and instead obtain the packm kernel from the cntx_t.
- Added bli_calloc_intl(), which serves as the calloc-equivalent to to
bli_malloc_intl(). Useful when we wish to allocate and initialize to
zero/NULL.
- Converted existing cpp macro functions defined in bli_blksz.h, bli_func.h,
bli_cntx.h into static functions.
Details:
- Added an option to configure that allows the user to force an arbitrary
version string at configure-time. The help text also now describes the
usage information.
- Changed the way the version string is communicated to the Makefile.
Previously, it was read into the VERSION variable from the 'version' file
via $(shell cat ...). Now, the VERSION variable is instead set in
config.mk (via a configure-substituted anchor from config.mk.in).
Details:
- Updated the top-level Makefile, build/config.mk.in template, and
configure script so that object files corresponding to source files
belonging to the BLAS compatibility layer are not compiled (or archived)
when the compatibility layer is disabled. (Same for CBLAS.) Thanks
to Devin Matthews for suggesting this optimization.
- Slight change to the way configure handles internal variables. Instead
of converting (overwriting) some, such as enable_blas2blis and
enable_cblas, from a "yes" or "no" to a "1" or "0" value, the latter are
now stored in new variables that live alongside the originals (with the
suffix "_01"). This is convenient since some values need to be
sed-substituted into the config.mk.in template, which requires "yes" or
"no", while some need to be written to the bli_config.h.in template,
which requires "0" or "1".
- Add missing axpby and xpby operations (plus test cases).
- Add special case for scal2v with alpha=1.
- Add restrict qualifiers.
- Add special-case algorithms for incx=incy=1.
Options to configure have been added for:
- Setting the internal BLIS and BLAS/CBLAS integer sizes.
- Enabling and disabling the BLAS and CBLAS layers.
Additionally, configure options which require defining macros (the above plus the threading model), write their macros to the automatically-generated bli_config.h file in the top-level build directory. The old bli_config.h files in the config dirs were removed, and any kernel-related macros (SIMD size and alignment etc.) were moved to bli_kernel.h. The Makefiles were also modified to find the new bli_config.h file.
Lastly, support for OMP in clang has been added (closes#56).
Details:
- Updated the top-level Makefile so that the CFLAGS variable designated
for kernel source code is applied not only to source code in
directories named "kernels" but source code in any directory that
contains the substring "kernels", such as "ukernels".
- Formally disabled some code in gen-make-frag.sh script that was already
effectively disabled. The code was related to handling "noopt" and
"kernel" directories, which is now handled independently within the
top-level Makefile without needing to place these source files into
a spearate makefile variable.
1) Add -- options.
2) Add -d/--enable-debug option to enable debugging symbols with and without optimization.
3) Allow user to specify CC at configure time, and determine vendor (gcc/icc/etc.). For now configurations enforce a particular vendor.
4) Add make V=[0,1] option to control build verbosity.
Details:
- Applied a patch that allows the top-level Makefile to work on certain
systems. The patch simply separates out the source-to-object code
generation rules for .c and .S files into two separate rules. Thanks
to Devin Matthews for submitting this patch.
When installing to a directory which is not owned by the installing
user, even when the user has write permission for the directory, the
installation can fail with an error similar to the following:
Installing libblis-0.1.4-7-sandybridge.a into /usr/local/lib/
install: cannot change permissions of ‘/usr/local/lib’: Operation not permitted
Makefile:658: recipe for target '/usr/local/lib/libblis-0.1.4-7-sandybridge.a' failed
make: *** [/usr/local/lib/libblis-0.1.4-7-sandybridge.a] Error 1
In the example case, the error occurred because the user attempted to
install to /usr/local and /usr/local/lib is owned by root with mode 2755
which the Makefile unsuccessfully attempted to change to 0755.
Given that installing to /usr/local is likely to be quite common and the
ownership/permissions are the default for Debian and Debian-derived
Linux distributions (perhaps others as well), this commit attempts to
support that use case by using mkdir rather than install to create the
directory (which is the same approach as Automake).
