            Bug ID: 96513
           Summary: building terminated with -O3
           Product: gcc
           Version: 9.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

-Itest wtk/core/fft/wtk_fixfft.c

when I compile use above command I got this

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-9/README.Bugs> for instructions.

only -O3 got this error, -O2 is normal. Sorry, I can't submit source code as it
is not my personal code.

What you could do, even if it is private code, is reduce it
(https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction) until it is very small
and doesn't give away any IP, and then post it. Otherwise, there is not much we
can do from your report and we are probably just going to close it...

Started with r9-3644-g4dd7c0dcd87c86aa and got fixed on master with
r11-72-gfae545fb03397034.
It's still ICEing on gcc-9 and gcc-10 branches.

Thank you for the report!

Clearly the old hybrid detection could never have worked with pattern
sequences.

    tree-optimization/96513 - rewrite hybrid SLP detection

    This rewrites hybrid SLP detection to be simpler and cope with
    group size changes in the SLP graph.  In particular detection
    works starting from non-SLP stmts following use->def chains
    rather than walking the SLP graph and following def->use chains.

    This picks a rewrite from GCC 11 for the old code didn't handle
    pattern sequences correctly.
