Details:
- After merging PR #303, at Isuru's request, I removed the use of
BLIS_EXPORT_BLIS from all function prototypes *except* those that we
potentially wish to be exported in shared/dynamic libraries. In other
words, I removed the use of BLIS_EXPORT_BLIS from all prototypes of
functions that can be considered private or for internal use only.
This is likely the last big modification along the path towards
implementing the functionality spelled out in issue #248. Thanks
again to Isuru Fernando for his initial efforts of sprinkling the
export macros throughout BLIS, which made removing them where
necessary relatively painless. Also, I'd like to thank Tony Kelman,
Nathaniel Smith, Ian Henriksen, Marat Dukhan, and Matthew Brett for
participating in the initial discussion in issue #37 that was later
summarized and restated in issue #248.

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:
- Implemented support for gemm where A, B, and C may have different
storage datatypes, as well as a computational precision (and implied
computation domain) that may be different from the storage precision
of either A or B. This results in 128 different combinations, all
which are implemented within this commit. (For now, the mixed-datatype
functionality is only supported via the object API.) If desired, the
mixed-datatype support may be disabled at configure-time.
- Added a memory-intensive optimization to certain mixed-datatype cases
that requires a single m-by-n matrix be allocated (temporarily) per
call to gemm. This optimization aims to avoid the overhead involved in
repeatedly updating C with general stride, or updating C after a
typecast from the computation precision. This memory optimization may
be disabled at configure-time (provided that the mixed-datatype
support is enabled in the first place).
- Added support for testing mixed-datatype combinations to testsuite.
The user may test gemm with mixed domains, precisions, both, or
neither.
- Added a standalone test driver directory for building and running
mixed-datatype performance experiments.
- Defined a new variation of castm, castnzm, which operates like castm
except that imaginary values are not touched when casting a real
operand to a complex operand. (By contrast, in these situations castm
sets the imaginary components of the destination matrix to zero.)
- Defined bli_obj_imag_is_zero() and substituted calls in lieu of all
usages of bli_obj_imag_equals() that tested against BLIS_ZERO, and
also simplified the implementation of bli_obj_imag_equals().
- Fixed bad behavior from bli_obj_is_real() and bli_obj_is_complex()
when given BLIS_CONSTANT objects.
- Disabled dt_on_output field in auxinfo_t structure as well as all
accessor functions. Also commented out all usage of accessor
functions within macrokernels. (Typecasting in the microkernel is
still feasible, though probably unrealistic for now given the
additional complexity required.)
- Use void function pointer type (instead of void*) for storing function
pointers in bli_l0_fpa.c.
- Added documentation for using gemm with mixed datatypes in
docs/MixedDatatypes.md and example code in examples/oapi/11gemm_md.c.
- Defined level-1d operation xpbyd and level-1m operation xpbym.
- Added xpbym test module to testsuite.
- Updated frame/include/bli_x86_asm_macros.h with additional macros
(courtsey of Devin Matthews).
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.
Details:
- Implemented castm and castv operations, which behave like copym and
copyv except where the obj_t operands can be of different datatypes.
These new operations, however, unlike copym/copyv, do not build upon
existing level-1v kernels.
- Reorganized projm, projv into a 'proj' subdirectory of frame/base (to
match the newly added frame/base/cast directory).
- Added new macros to bli_gentfunc_macro_defs.h, _gentprot_macro_defs.h
that insert GENTFUNC2/GENTPROT2 macros for all non-homogeneous datatype
combinations. Previously, one had to invoke two additional macros--one
which mixed domains only and another that included all remaining
cases--in order to get full type combination coverage.
- Defined a new static function, bli_set_dims_incs_2m(), to aid in the
setting of various variables in the implementations of bli_??castm().
This static function joins others like it in bli_param_macro_defs.h.
- Comment update to bli_copysc.h.
