Bug ID: 90555
Summary: IPA ICF should compare selected struct cfgloop members
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Consider gcc.target/i386/avx512f-simd-1.c testcase with sed -ie 's/ [23];/ 1/g'
IPA ICF happily merges the functions, even when struct cfgloop members say that
the loops in there should be vectorized differently.
I think IPA ICF should punt if cfgloop simdlen, safelen, can_be_parallel,
dont_vectorize, force_vectorize, unroll members are different, and for simduid
should verify the there mentioned decl, if it is the corresponding one between
the two ILs.
