Here are some more details about the bootstrap failure with
varasm.c.
The first substantive comparison difference, beyond things like
varasm.c.00.rtl:
107300c107300
< (note 9 7 11 0x200000a5680 NOTE_INSN_BLOCK_BEG)
---
> (note 9 7 11 0x2000008f680 NOTE_INSN_BLOCK_BEG)
comes in the dump of the gcse pass. The .i file and gcse dumps of the
stage1 and stage2 compilers on varasm.c can be found at
http://www.math.purdue.edu/~lucier/stage1-varasm.c.09.gcse.gz
http://www.math.purdue.edu/~lucier/stage2-varasm.c.09.gcse.gz
http://www.math.purdue.edu/~lucier/varasm.i.gz
I can't find evidence of a good 3.1 bootstrap on alpha since May 11.
The stage1 compiler was built with gcc-2.95.1.
