Added extensive support for configuration defaults.
Details:
- Standard names for reference kernels (levels-1v, -1f and 3) are now
macro constants. Examples:
BLIS_SAXPYV_KERNEL_REF
BLIS_DDOTXF_KERNEL_REF
BLIS_ZGEMM_UKERNEL_REF
- Developers no longer have to name all datatype instances of a kernel
with a common base name; [sdcz] datatype flavors of each kernel or
micro-kernel (level-1v, -1f, or 3) may now be named independently.
This means you can now, if you wish, encode the datatype-specific
register blocksizes in the name of the micro-kernel functions.
- Any datatype instances of any kernel (1v, 1f, or 3) that is left
undefined in bli_kernel.h will default to the corresponding reference
implementation. For example, if BLIS_DGEMM_UKERNEL is left undefined,
it will be defined to be BLIS_DGEMM_UKERNEL_REF.
- Developers no longer need to name level-1v/-1f kernels with multiple
datatype chars to match the number of types the kernel WOULD take in
a mixed type environment, as in bli_dddaxpyv_opt(). Now, one char is
sufficient, as in bli_daxpyv_opt().
- There is no longer a need to define an obj_t wrapper to go along with
your level-1v/-1f kernels. The framework now prvides a _kernel()
function which serves as the obj_t wrapper for whatever kernels are
specified (or defaulted to) via bli_kernel.h
- Developers no longer need to prototype their kernels, and thus no
longer need to include any prototyping headers from within
bli_kernel.h. The framework now generates kernel prototypes, with the
proper type signature, based on the kernel names defined (or defaulted
to) via bli_kernel.h.
- If the complex datatype x (of [cz]) implementation of the gemm micro-
kernel is left undefined by bli_kernel.h, but its same-precision real
domain equivalent IS defined, BLIS will use a 4m-based implementation
for the datatype x implementations of all level-3 operations, using
only the real gemm micro-kernel.
Added object wrappers to 1f test suite modules. Details: - Added missing object wrappers to level-1f test suite modules. This was only apparent if you were configuring with something other than the reference configuration. - Commented out object-wrappers in level-1f front-ends. These were not working as intended the reference configuration was selected, because most kernel sets, such as those in the template set, do not have object wrappers. - Whitespace changes to template micro-kernels. - Comment changes to template level-1f kernel headers.
Added BLAS error checking to compatibility layer. Details: - Added frame/compat/check directory, which now houses companion _check() routines for each of the BLAS wrappers in frame/compat. These _check() routines are called from the compatibility wrappers and mimic the error-checking present in the netlib BLAS. - Edited bla_xerbla.c so that xerbla() translates the operation string to uppercase before printing. - Redefined util routines in frame/compat/f2c/util in terms of level0 macros. - Added prototypes for util routines, f2c routines, lsame(), and xerbla(). - Commented out prototypes in test/test_*.c since Fortran integers are now int64_t by default (and the prototypes that were present in the files used int). - Removed redundant #include "bli_f2c.h" in bli_?lamch.c and bli_lsame.c, since blis.h was already being included. - Other minor changes to code in frame/compat/f2c.
