            Bug ID: 113768
           Summary: gm2/extensions/run/pass/vararg2.mod FAILs
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: gaius at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc*-sun-solaris2.11, s390x-ibm-linux-gnu,
                    m68k-unknown-linux-gnu

The gm2/extensions/run/pass/vararg2.mod test FAILs on Solaris/SPARC (32 and
64-bit) since its introduction:

FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O=20
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O -g=20
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O3 -fomit-frame-poin=
ter=20
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O3 -fomit-frame-poin=
ter
-finline-functions=20
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -Os=20
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -g=20

There are also gcc-testresults reports for Linus/s390x and Linux/m68k.

On Solaris, the test prints

parameter is hello world and length 0
executed
/var/gcc/regression/master/11.4-gcc/build/gcc/testsuite/gm21/vararg2.x0 with
result fail

All affected targets are big-endian, though I don't yet see how this affects
the test.=
