Details:
- Use -qopenmp-simd instead of -fopenmp-simd when compiling with Intel
icc. Recall that this option is used for SIMD auto-vectorization in
reference kernels only. Support for the -f option has been completely
deprecated and removed in newer versions of icc in favor of -q. Thanks
to Victor Eijkhout for reporting this issue and suggesting the fix.
Details:
- Attempted a fix to issue #313, which reports that when building only
a shared library (ie: static library build is disabled), running the
BLAS test drivers can fail because those drivers provide their own
local version of xerbla_() as a clever (albeit still rather hackish)
way of checking the error codes that result from the individual tests.
This local xerbla_() function is never found at link-time because the
BLAS test drivers' Makefile imports BLIS compilation flags via the
get-user-cflags-for() function, which currently conveys the
-fvisibility=hidden flag, which hides symbols unless they are
explicitly annotated for export. The -fvisibility=hidden flag was
only ever intended for use when building BLIS (not for applications),
and so the attempted solution here is to omit the symbol export
flag(s) from get-user-cflags-for() by storing the symbol export
flag(s) to a new BULID_SYMFLAGS variable instead of appending it
to the subconfigurations' CMISCFLAGS variable (which is returned by
every get-*-cflags-for() function). Thanks to M. Zhou for reporting
this issue and also to Isuru Fernando for suggesting the fix.
- Renamed BUILD_FLAGS to BUILD_CPPFLAGS to harmonize with the newly
created BUILD_SYMFLAGS.
- Fixed typo in entry for --export-shared flag in 'configure --help'
text.
Export macros can't support both shared and static at the same time.
When blis is built with both shared and static, headers assume that
shared is used at link time and dllimports the symbols with __imp_
prefix.
To use the headers with static libraries a user can give
-DBLIS_EXPORT= to import the symbol without the __imp_ prefix
Details:
- Replaced the existing --enable-export-all / --disable-export-all
configure option with --export-shared=[public|all], with the 'public'
instance of the latter corresponding to --disable-export-all and the
'all' instance corresponding to --enable-export-all. Nothing else
semantically about the option, or its default, has changed.
Details:
- Modified common.mk to use the -fvisibility=[hidden|default] option
when compiling with clang on non-Windows platforms (Linux, BSD, OS X,
etc.). Thanks to Isuru Fernando for pointing out this option works
with clang on these OSes.
Details:
- Introduced a new configure option, --enable-export-all, which will
cause all shared library symbols to be exported by default, or,
alternatively, --disable-export-all, which will cause all symbols to
be hidden by default, with only those symbols that are annotated for
visibility, via BLIS_EXPORT_BLIS (and BLIS_EXPORT_BLAS for BLAS
symbols), to be exported. The default for this configure option is
--disable-export-all. Thanks to Isuru Fernando for consulting on
this commit.
- Removed BLIS_EXPORT_BLIS annotations from frame/1m/bli_l1m_unb_var1.h,
which was intended for 5a5f494.
- Relocated BLIS_EXPORT-related cpp logic from bli_config.h.in to
frame/include/bli_config_macro_defs.h.
- Provided appropriate logic within common.mk to implement variable
symbol visibility for gcc, clang, and icc (to the extend that each of
these compilers allow).
- Relocated --help text associated with debug option (-d) to configure
slightly further down in the list.
* Revert "restore bli_extern_defs exporting for now"
This reverts commit 09fb07c350b2acee17645e8e9e1b8d829c73dca8.
* Remove symbols not intended to be public
* No need of def file anymore
* Fix whitespace
* No need of configure option
* Remove export macro from definitions
* Remove blas export macro from definitions
Details:
- Rewrote level-1v, -1f, and -3 reference kernels in terms of simplified
indexing annotated by the #pragma omp simd directive, which a compiler
can use to vectorize certain constant-bounded loops. (The new kernels
actually use _Pragma("omp simd") since the kernels are defined via
templatizing macros.) Modest speedup was observed in most cases using
gcc 5.4.0, which may improve with newer versions. Thanks to Devin
Matthews for suggesting this via issue #286 and #259.
- Updated default blocksizes defined in ref_kernels/bli_cntx_ref.c to
be 4x16, 4x8, 4x8, and 4x4 for single, double, scomplex and dcomplex,
respectively, with a default row preference for the gemm ukernel. Also
updated axpyf, dotxf, and dotxaxpyf fusing factors to 8, 6, and 4,
respectively, for all datatypes.
- Modified configure to verify that -fopenmp-simd is a valid compiler
option (via a new detect/omp_simd/omp_simd_detect.c file).
- Added a new header in which prefetch macros are defined according to
which compiler is detected (via macros such as __GNUC__). These
prefetch macros are not yet employed anywhere, though.
- Updated the year in copyrights of template license headers in
build/templates and removed AMD as a default copyright holder.
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:
- Moved windows/build/libblis-symbols.def to build/libblis-symbols.def.
Updated link commands in common.mk accordingly.
- Added a new script build/regen-symbols.sh that will regenerate the
libblis-symbols.def file in its new location after building a
haswell-targeted shared library. Thanks to Isuru Fernando for
providing the symbol generation command.
- Ran the new script to refresh the symbols file.
Details:
- Execute build/flatten-headers.py python script via $(PYTHON) in
common.mk. This allows distributions that define the current/preferred
python interpreter in the PYTHON environment variable to use that
interpreter when executing flatten-headers.py. Thanks to Isuru
Fernando for this suggestion, and for Dave Love for submitting the
initial issue/request.
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:
- Tweaked the cflags functions in common.mk so that a new preprocessor
macro, BLIS_IS_BUILDING_LIBRARY, is defined, but only when BLIS
itself is being built. This macro will not be defined when, for
example, the testsuite or example code compiles code local to those
applications. This was done in part by defining a new cflags function
get-user-cflags-for(), which is now the designated function for
application Makefiles if they wish to inherit a basic set of CFLAGS
from BLIS. (The compiler flags returned are identical to that of
get-frame-cflags-for() except that -DBLIS_IS_BUILDING_LIBRARY is
omitted.)
- Updated all test driver-like makefiles to call get-user-cflags-for()
instead of get-frame-cflags-for().
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:
- 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:
- Any preexisting values set to the CFLAGS environment variable (or the
CFLAGS variable if given on the command line) are saved by configure
for later inclusion (prepending, to be precise) along with the
compiler flags automatically determined by the BLIS build system.
LDFLAGS is treated in a similar manner.) Thanks to Dave Love for
requesting this feature in issue #223 and Mathieu Poumeyrol for his
support on this and a previous related issue.
- Comment updates to build/config.mk.in.
- Strip whitespace from return value of various cflags functions in
common.mk.
Details:
- Fixed configure so that MK_ENABLE_MEMKIND is assigned "no" when the
option is disabled due to libmemkind not being present. This wasn't
affecting anything since the one use of the variable (in common.mk)
was formulated as "ifeq ($(MK_ENABLE_MEMKIND),yes)". That is, the
variable being empty was effectively equivalent to it being set to
"no".
- Comment updates to build/config.mk.in, common.mk.
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:
- Historically, the compiler selection has happened statically in the
various make_defs.mk and would only be overriden by setting CC (either
prior to running configure or as a configure argument). However, in
the last couple months, configure has evolved to contain rather
sophisticated compiler detection logic for the purposes of blacklisting
sub-configurations. It only makes sense that configure now fully take
over the responsibility of selecting a compiler from the GNU make side
of the build system. Thanks to Alex Arslan for his help exposing this
issue.
- Substitute found_cc into CC in config.mk via configure.
- Set a new variable, CC_VENDOR, in config.mk via substitution from
configure, and disable the corresponding CC_VENDOR code in common.mk.
- Disabled default compiler selection (usually gcc) in the sub-configs'
various make_def.mk files.
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:
- 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:
- Added bli_setgetijm.c, which defines bli_setijm(), bli_getijm(), and
related functions that can be used to read and write individual
elements of an obj_t.
- Defined a new function, bli_obj_create_conf_to(), in bli_obj.c that will
create a new object with dimensions conformal to an existing object.
Transposition and conjugation states on the existing object are ignored,
as are structure and uplo fields.
- Defined a new function, bli_datatype_string(), in bli_obj.c that returns
a char* to a string representation of the name of each num_t datatype.
For example, BLIS_DOUBLE is "double" and BLIS_DCOMPLEX is "dcomplex".
BLIS_INT is included (as "int"), but BLIS_CONSTANT is not, and thus is
not a valid input argument to bli_datatype_string().
- Added calls to bli_init_once() to various functions in bli_obj.c, the
most important of which was bli_obj_create_without_buffer().
- Removed unintended/extra newline from the end of printv output.
- Whitespace changes to
- frame/base/bli_machval.c
- frame/base/bli_machval.h
- frame/0/copysc/bli_copysc.c
- Trivial changes to README.md and common.mk.
Details:
- Removed some old conditional code in config/knl/make_defs.mk that
added -lmemkind to LDFLAGS if DEBUG_TYPE was not 'sde' and inserted
code into common.mk that affirmatively filters out -lmemkind from
LDFLAGS if DEBUG_TYPE is 'sde'. (Thanks to Dave Love for reporting
this issue.) Other minor cleanups to neighboring code in common.mk.
- Updated CRVECFLAGS in knl/make_defs.mk to be based on -march=knl,
and then AVX-512 functionality is manually removed via various
-mno-avx512* flags. Also, make the setting of CRVECFLAGS conditional
on CC_VENDOR. Similar change to skx/make_defs.mk.
- Comment/whitespace updates.
Details:
- Renamed CVECFLAGS variables in sub-configurations' make_defs.mk files
to CKVECFLAGS.
- Added default defintions of two new make variables to most sub-
configurations' make_defs.mk files--CROPTFLAGS and CRVECFLAGS--
which correspond to reference kernel analogues of the CKOPTFLAGS
and CKVECFLAGS, which track optimization and vectorization flags for
optimized kernels. Currently, two sub-configurations (knl and skx)
explicitly set CRVECFLAGS to non-default values (using AVX2 instead of
AVX-512 for reference kernels. Thanks to Jeff Hammond, whose feedback
prompted me to make this change (issue #187).
- Changed common.mk so that the get-refkern-cflags-for function returns
the flags associated with the given sub-configuration's CROPTFLAGS
and CRVECFLAGS (instead of CKOPTFLAGS and CKVECFLAGS).
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.
