As originally reported in PR tree-optimization/92683, the gcc.dg/strcmpopt_8.c
test still FAILs on both Solaris/x86 and SPARC:
* on x86 with -m64 only:
FAIL: gcc.dg/strcmpopt_8.c scan-tree-dump-not forwprop1 "strncmp"
* on sparc with -m64 only:
FAIL: gcc.dg/strcmpopt_8.c (test for excess errors)

FAIL: gcc.dg/strcmpopt_8.c scan-tree-dump-not forwprop1 "strncmp"
This only happens with 32-bit-default compilers, the corresponding
64-bit-default
compilers don't show the failure.
I'm attaching both the amd64 and sparcv9 dumps (which are effectively
identical).
