9d76688ad9 Fix for single rank crash with HPL application. When computing offset of C buffer, as integer variables are used for a row and column index, the intermediate result value overflows and a negative value gets added to the buffer, when the negative value is too large it would index the buffer out of the range resulting in segmentation fault. Although the crash is a result of dgemm kernel, added similar code in sgemm kernel also.

3a929a3d0b Fixed code merging: bli_gemm_small.c - missed conditional checks for L!=0 && K!=0. Now they are added. This fix is done to pass blastest

0645f239fb Remove UT-Austin from copyright headers' clause 3.
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.

5140ee3424 Updated types of bli_is_[un]aligned_to() functions.
Details:
- Changed the void* arguments of the following static functions:
    bli_is_aligned_to()
    bli_is_unaligned_to()
    bli_offset_past_alignment()
  to siz_t, and the return type of bli_offset_past_alignment() from
  guint_t to siz_t. This allows for more versatile usage of these
  functions (e.g. when aligning both pointers and leading dimension).
- Updated all invocations of these functions, mostly in kernels/penryn
  but also in kernels/bgq, to include explicit typecasts to siz_t when
  pointer arguments are passed in.
- Thanks to Devin Matthews for pointing out this potential bug (via issue
  #211).
- Deleted a few trailing spaces in various penryn kernels.
- Removed duplicate instances of the words "derived" and "THEORY" from
  various kernel license headers, likely from a malformed recursive sed
  performed long ago.

4b36e85be9 Converted function-like macros to static functions.
Details:
- Converted most C preprocessor macros in bli_param_macro_defs.h and
  bli_obj_macro_defs.h to static functions.
- Reshuffled some functions/macros to bli_misc_macro_defs.h and also
  between bli_param_macro_defs.h and bli_obj_macro_defs.h.
- Changed obj_t-initializing macros in bli_type_defs.h to static
  functions.
- Removed some old references to BLIS_TWO and BLIS_MINUS_TWO from
  bli_constants.h.
- Whitespace changes in select files (four spaces to single tab).

16813335bd Merge branch 'amd' into rt
Details:
- Merged contributions made by AMD via 'amd' branch (see summary below).
  Special thanks to AMD for their contributions to-date, especially with
  regard to intrinsic- and assembly-based kernels.
- Added column storage output cases to microkernels in
  bli_gemm_zen_asm_d6x8.c and bli_gemmtrsm_l_zen_asm_d6x8.c. Even with
  the extra cost of transposing the microtile in registers, this is
  much faster than using the general storage case when the underlying
  matrix is column-stored.
- Added s and d assembly-based zen gemmtrsm_u microkernel (including
  column storage optimization mentioned above).
- Updated zen sub-configuration to reflect presence of new native
  kernels.
- Temporarily reverted zen sub-configuration's level-3 cache blocksizes
  to smaller haswell values.
- Temporarily disabled small matrix handling for zen configuration
  family in config/zen/bli_family_zen.h.
- Updated zen CFLAGS according to changes in 1e4365b.
- Updated haswell microkernels such that:
  - only one vzeroupper instruction is called prior to returning
  - movapd/movupd are used in leiu of movaps/movups for double-real
    microkernels. (Note that single-real microkernels still use
    movaps/movups.)
- Added kernel prototypes to kernels/zen/bli_kernels_zen.h, which is
  now included via frame/include/bli_arch_config.h.
- Minor updates to bli_amaxv_ref.c (and to inlined "test" implementation
  in testsuite/src/test_amaxv.c).
- Added early return for alpha == 0 in bli_dotxv_ref.c.
- Integrated changes from f07b176, including a fix for undefined
  behavior when executing the 1m method under certain conditions.
- Updated config_registry; no longer need haswell kernels for zen
  sub-configuration.
- Tweaked marginal and pass thresholds for dotxf.
- Reformatted level-1v, -1f, and -3 amd kernels and inserted additional
  comments.
- Updated LICENSE file to explicitly mention that parts are copyright
  UT-Austin and AMD.
- Added AMD copyright to header templates in build/templates.

Summary of previous changes from 'amd' branch.
- Added s and d assembly-based zen gemm microkernels (d6x8 and d8x6) and
  s and d assembly-based zen gemmtrsm_l microkernels (d6x8).
- Added s and d intrinsics-based zen kernels for amaxv, axpyv, dotv, dotxv,
  and scalv, with extra-unrolling variants for axpyv and scalv.
- Added a small matrix handler to bli_gemm_front(), with the handler
  implemented in kernels/zen/3/bli_gemm_small_matrix.c.
- Added additional logic to sumsqv that first attempts to compute the
  sum of the squares via dotv(). If there is a floating-point exception
  (FE_OVERFLOW), then the previous (numerically conservative) code is
  used; otherwise, the result of dotv() is square-rooted and stored as
  the result. This new implementation is only enabled when FE_OVERFLOW
  is #defined. If the macro is not #defined, then the previous
  implementation is used.
- Added axpyv and dotv standalone test drivers to test directory.
- Added zen support to old cpuid_x86.c driver in build/auto-detect/old.
- Added thread-local and __attribute__-related macros to bli_macro_defs.h.
