- Subject: Question about the internal compiler error in verify_local_live_at_start
Hello,
When I run the test suite for my port of gcc, there are some failures
caused by the optimization flag such as -O2/-O3, and the messages are
like,
930120-1.c: In function `f':
930120-1.c:138: internal compiler error: in verify_local_live_at_start, at flow.
c:546
It seems that because of the regsets doesn't match after reload. But
can you give me any clues? I think it's hard to check the bugs.
Thanks a lot.
Eric.
