As noted here:
http://gcc.gnu.org/ml/gcc-testresults/2003-04/msg00685.html
I'm getting testsuite failures in g++.dg/eh/simd-1.C and g++.dg/eh/simd-2.C with mainline gcc-3.4.
Both involve compiler crashes that look like this:
simd-1.C:11: internal compiler error: in function_arg_slotno, at config/sparc/sparc.c:4526
Running simd-1.C under gdb, it gets into sparc.c:function_arg_slotno and enters a switch on a mode of V2SImode. This mode isn't handled so it goes into the default abort clause and crashes.
The simd-2.C test does the same, except it enters with a mode of V4SImode.
>How-To-Repeat:
Target sparc-sun-solaris2.7 and compile simd-1.ii with:
cc1plus -fpreprocessed simd-1.ii -quiet -dumpbase simd-1.C -auxbase simd-1 -O -version -fmessage-length=0 -o simd-1.s
or compile simd-2.ii with:
cc1plus -fpreprocessed simd-2.ii -quiet -dumpbase simd-2.C -auxbase simd-2 -O -version -fmessage-length=0 -o simd-2.s
