--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
G was fixed in GCC 10 by r10-4004-g15643a0dfc60e8 (aka PR 92140):
cmpl $1, %edi
movl %edi, %eax
adcl $0, %eax
That was all that was left to fix here so closing as such.

Add a != MIN/MAX_VALUE_CST ? CST-+1 : a to minmax_from_comparison
This patch adds the support for match that was implemented for PR 87913 in
phiopt.
It implements it by adding support to minmax_from_comparison for the check.
It uses the range information if available which allows to produce MIN/MAX
expression
when comparing against the lower/upper bound of the range instead of
lower/upper
of the type.
minmax-20.c is the new testcase which tests the ranges part.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
* fold-const.cc (minmax_from_comparison): Add support for NE_EXPR.
* match.pd ((cond (cmp (convert1? x) c1) (convert2? x) c2)
pattern):
Add ne as a possible cmp.
((a CMP b) ? minmax<a, c> : minmax<b, c> pattern): Likewise.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/minmax-22.c: New test.
