>Description:
I'm getting a testsuite failure for g++.dg/abi/empty6.C on mips-sgi-irix6.5 as seen here: http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg00233.html
The error is not new, it appears to have started from the very day the testcase was checked in: http://gcc.gnu.org/ml/gcc-testresults/2002-09/msg00909.html
The logfile says:
FAIL: g++.dg/abi/empty6.C (test for warnings, line 6)
and indeed no -Wabi warning is issued. The failure occurs only when I run the testsuite with -mabi=64, it succeeds without that flag as noted in the test report above.
>How-To-Repeat:
Target mips-sgi-irix6.5 and compile empty6.ii with:
cc1plus -fpreprocessed empty6.ii -quiet -dumpbase empty6.C -mabi=64 -auxbase-strip empty6.C -Wabi -version -fmessage-length=0 -o empty6.C
and note that no -Wabi warning is issued.
