Description Kaveh Ghazi 2002-04-18 09:56:01 UTC 
When I run the testsuite with -mips4, I get this additional failure:

 > FAIL: gcc.c-torture/compile/920501-4.c,  -O1  

See: http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg00671.html

When I compile it by hand, I get:
 > xgcc -mips4 -c -O 920501-4.c
 > 920501-4.c: In function `foo':
 > 920501-4.c:49: Internal compiler error in gen_reload_outcc, at insn-emit.c:7493

This failure does not occur with e.g. gcc-2.8.1

Release:
3.1 20020417

Environment:
mips-sgi-irix6.2 native as/ld
