Details:
- Fixed a bug in bli_cntx_set_ukr_prefs() which erroneously typecast the
num_t value read from va_args() down to a bool before being stored
within the cntx_t. This bug was introduced on April 6th 2022, in
ae10d94. This caused the ukernel preferences for double real and
double complex to go unchanged while the preferences for single real
and single complex were corrupted by the former datatypes'
preference values. The bug manifested as degraded performance for
subconfigurations that registered column-preferential ukernels. The
reason is that the erroneous preferences trigger unnecessary
transpositions in the operation, which forces the gemm ukernel to
compute on matrices that are not stored according to its preference.
Thanks to Devin Matthews, Jeff Diamond, and Leick Robinson for their
extensive efforts and assistance in tracking down this issue.
- Augmented the informational header that is output by the testsuite to
include ukernel preferences for gemm, gemmtrsm_[lu], and trsm_[lu].
- CREDITS file update.
