Subject: AMDGPU: Remove unnecessary check for isFullCopy
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=70b19478024540b58b1e6fb9ee853fcaf5481160;p=llvm

AMDGPU: Remove unnecessary check for isFullCopy

Subregister indexes are not used for physical register operands, so
isFullCopy is implied by the physical register check.
