            Bug ID: 103470
           Summary: [10, 11, 12] GNU-stack section not emitted on MIPS
                    hard-float targets with MUSL
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lipnitsk at gmail dot com
  Target Milestone: ---

MUSL follow-up to
https://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommit;h=3D54b3d52c3cca836c7c4c08c=
c9c02eda6c096372a

This change should be back-ported (easy cherry-pick) to releases that conta=
in
54b3d52c3cca836c7c4c08cc9c02eda6c096372a

Proposed patch and discussion:
https://gcc.gnu.org/pipermail/gcc-patches/2021-November/584553.html

>>From email thread:
musl only uses PT_GNU_STACK to set default thread stack size and has no
executable stack support[0], so there is no reason not to emit the
.note.GNU-stack section on musl builds.
