            Bug ID: 31244
           Summary: pthread_cancel hangs on sparc32
           Product: glibc
           Version: 2.38
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: nptl
          Assignee: unassigned at sourceware dot org
          Reporter: cederman at gaisler dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

Created attachment 15301
  --> https://sourceware.org/bugzilla/attachment.cgi?id=15301&action=edit
Patch that has also been posted on the glibc list.

The signal return stub functions were changed from inline assembly to pure
assembly. After that the test tst-mutex8-static started to fail (timing
dependent on hardware, but always in QEMU user mode) as well as the tests
cleanup-8 and cleanup-10 in the GCC testsuite.

One of the indirect changes from the rewrite was that the functions got unwind
information. Removing this information and adding a bit of padding causes the
tests to pass.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
A similar failure also happens on sparc64:

FAIL: nptl/tst-cancel24-static
FAIL: nptl/tst-cond8-static
FAIL: nptl/tst-mutex8-static
FAIL: nptl/tst-mutexpi8-static
FAIL: nptl/tst-mutexpi9

I will sent a similar fix as proposed to sparc32 [1].

Can this be backported to 2.37 and 2.38?
