            Bug ID: 25671
           Summary: tst-cond8-static failing on sparc64 on Linux
           Product: glibc
           Version: 2.32
               URL: https://buildd.debian.org/status/fetch.php?pkg=glibc&a
                    rch=sparc64&ver=2.31-0experimental0&stamp=1584003885&r
                    aw=0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ports
          Assignee: unassigned at sourceware dot org
          Reporter: glaubitz at physik dot fu-berlin.de

  Target Milestone: ---
            Target: sparc*-*-*

With 2.31, the number of testsuite failures on Linux/sparc64 has dropped
dramatically to just three failures. One of the failures left is
nptl/tst-cond8-static, for a full log see:
https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=sparc64&ver=2.31-0experimental0&stamp=1584003885&raw=0

Is this a failure which can be safely ignored or does it indicate a larger
problem?

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
It is the same issue from BZ#31244, where the rewrite done by
b33e946fbb1659d2c5937c4dd756a7c49a132dff was not fully correct regarding CFI
annotation.  I will send a similar fix as proposed to fix the sparc32 issue:

It fixes the regression I saw on sparc64:

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