------- Comment #36 from ghazi at gcc dot gnu dot org 2007-06-30 02:16 -------
I tried --enable-checking=yes,fold on sparc-sun-solaris2.10, bootstrap works
but I'm still getting a few extra failures. Here are two testresults from the
same checkout, one regular and one with fold checking turned on:
http://gcc.gnu.org/ml/gcc-testresults/2007-06/msg01217.html
http://gcc.gnu.org/ml/gcc-testresults/2007-06/msg01270.html
The differences are:
> FAIL: g++.dg/gomp/atomic-10.C (internal compiler error)
> FAIL: g++.dg/gomp/atomic-4.C (internal compiler error)
> FAIL: gcc.dg/gomp/appendix-a/a.17.1.c (internal compiler error)

All of the failures are of the form:
internal compiler error: in fold_checksum_tree, at fold-const.c:12890
I'll create a testcase for one of them.
