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:
- Removed four trailing spaces after "BLIS" that occurs in most files'
commented-out license headers.
- Added UT copyright lines to some files. (These files previously had
only AMD copyright lines but were contributed to by both UT and AMD.)
- In some files' copyright lines, expanded 'The University of Texas' to
'The University of Texas at Austin'.
- Fixed various typos/misspellings in some license headers.
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.
