            Bug ID: 103420
           Summary: libatomic fails to compile on aarch64 linux with
                    TFLAGS=3D"-mcpu=3Docteontx2"
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P3
         Component: libgcc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64-linux-gnu

I was looking at the GCC patches that OpenEmbedded includes and found this =
one:
https://git.openembedded.org/openembedded-core/tree/meta/recipes-devtools/g=
cc/gcc/0037-libatomic-Do-not-enforce-march-on-aarch64.patch

Well I decided to figure out how to reproduce the failure and what I found =
is
if I use TFLAGS=3D"-mcpu=3Docteontx2" I run into the failure.=
