Most comments, including the second sentence in the head comment
of combine_validate_cost, the main decision-maker of the combine
pass, refer to the function as returning true if the new
insns(s) *cheaper* than the old insns, when in fact the function
returned true also if the cost was the same.
Hi:
This patch is about to support Intel Advanced Matrix Extensions (AMX)
which will be enabled in GLC.
AMX is a new 64-bit programming paradigm consisting of two
compo nents: a set of 2-dimensional registers (tiles) representing
sub-arrays from a larger 2-dimensional memory image,

TL;DR: fixing a misdetection of what is a "simple move".
Looking into performace degradation after de-cc0 for CRIS, I
noticed combine behaving badly; it changed a move and a
right-shift into two right-shifts, where the "combined" move was
not eliminated in later passes, and where the deficiency

for users/testers of GCC 11 as it evolves, and also helps not forget
things during the release process.
