------- Comment #6 from ebotcazou at gcc dot gnu dot org 2010-09-19 21:58 ------- tree-ssa-operands.c:copy_virtual_operands is miscompiled by delay slot scheduling so the workaround is to use STAGE1_CFLAGS="-O1 -fno-delayed-branch". Another way out is probably to configure with --disable-stage1-checking.
