--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fallout in GENERIC folding from doing that:

FAIL: c-c++-common/fold-divmul-1.c  -std=gnu++11  scan-tree-dump-not original
"/
\\\\[ex\\\\]"
FAIL: g++.dg/cpp1y/constexpr-array4.C  -std=c++14 (test for excess errors)
FAIL: g++.dg/ipa/devirt-28a.C  -std=gnu++11 (test for excess errors)
FAIL: g++.dg/gomp/declare-simd-3.C  -std=gnu++98  scan-assembler-times

FAIL: c-c++-common/fold-divmul-1.c  -Wc++-compat   scan-tree-dump-not original
"
/\\\\[ex\\\\]"
FAIL: gcc.dg/pr58742-1.c scan-tree-dump cddce1 "return e"

so for GENERIC the used types_match () is too strict it seems.
