Bug ID: 93063
Summary: Loop distribution and NOP conversions
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: missed-optimization
Severity: enhancement
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: glisse at gcc dot gnu.org
Target Milestone: ---
This comes from PR 93059.
void f(signed short*__restrict p,unsigned short*__restrict q,int n){
for(int i=0;i<n;++i)
*p++=*q++;
}
It would be nice if ldist could handle the NOP conversion and produce
memcpy/memmove as in the case without a conversion.
