Details:
- Fixed memory access bugs in the bli_sgemmsup_rv_haswell_asm_Mx2()
kernels, where M = {1,2,3,4,5,6}. The bugs were caused by loading four
single-precision elements of C, via instructions such as:
vfmadd231ps(mem(rcx, 0*32), xmm3, xmm4)
in situations where only two elements are guaranteed to exist. (These
bugs may not have manifested in earlier tests due to the leading
dimension alignment that BLIS employs by default.) The issue was fixed
by replacing lines like the one above with:
vmovsd(mem(rcx), xmm0)
vfmadd231ps(xmm0, xmm3, xmm4)
Thus, we use vmovsd to explicitly load only two elements of C into
registers, and then operate on those values using register addressing.
Thanks to Daniël de Kok for reporting these bugs in #635, and to
Bhaskar Nallani for proposing the fix).
- CREDITS file update.
