Subject: Re: [3.5 Regression] Several alpha testsuite regressions: gcc.c-torture/execute/ieee/fp-cmp-[458].c
After moving the new tests to gcc.c-torture/execute/ieee, all but two
failures are gone on alpha-dec-osf{4.0f, 5.1b}:
FAIL: gcc.c-torture/execute/ieee/compare-fp-1.c compilation, -O3 -fomit-frame-pointer
UNRESOLVED: gcc.c-torture/execute/ieee/compare-fp-1.c execution, -O3 -fomit-frame-pointer
FAIL: gcc.c-torture/execute/ieee/compare-fp-1.c compilation, -O3 -g
UNRESOLVED: gcc.c-torture/execute/ieee/compare-fp-1.c execution, -O3 -g
/vol/gnu/src/gcc/gcc-dist/gcc/testsuite/gcc.c-torture/execute/ieee/compare-fp-1.c: In function `main':
/vol/gnu/src/gcc/gcc-dist/gcc/testsuite/gcc.c-torture/execute/ieee/compare-fp-1.c:32: internal compiler error: Segmentation fault
It can be reproduced with
cc1 -O3 compare-fp-1.i
The stacktrace is as follows:
Program received signal SIGSEGV, Segmentation fault.
