            Bug ID: 107098
           Summary: [13 regression] failure in 453.povray
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal

Now at commit g:b7fd7fb5011106c062df9275ca8fddcbce4ebdeb, r13-2810=20

commit b7fd7fb5011106c062df9275ca8fddcbce4ebdeb
Author: Aldy Hernandez <aldyh@redhat.com>
Date:   Thu Sep 22 18:20:39 2022 +0200

    frange: drop endpoints to min/max representable numbers for
-ffinite-math-only.


This commit breaks one of the spec2006 test cases on powerpc64 LE

Running Benchmarks
  Running 453.povray ref base ppc64 default
453.povray: copy 0 non-zero return code (exit code=3D127, signal=3D0)
Invalid run; unable to continue.

Note that -ffinite-math-only is not used in compiling the source.  Sample
compilation:

/home/seurer/gcc/git/install/gcc-test/bin/g++ -c -o bcyl.o -DSPEC_CPU -DNDE=
BUG=20
 -m64 -O3 -mcpu=3Dpower8 -ffast-math -funroll-loops -fpeel-loops
-fvect-cost-model -mpopcntd -mrecip=3Drsqrt           bcyl.cpp

Or is that option included by one of the others?

I am not seeing anything in the log of the run that indicates what the error
was unfortunately.=
