A glance at AVR makes me think this should already be handled by
the NOTICE_UPDATE_CC machinery. Any analysis why this doesn't
happen? With the same test-case (at -Os) I don't see redundant
compares for cris-elf,
rtx_equal_p uses:
case SYMBOL_REF:
return XSTR (x, 0) == XSTR (y, 0);
to check whether two symbol_refs are equal. This means that genattrtab,
which uses rtx_equal_p, must create unique strings for them.
attr_rtx has code to create unique strings, and I think it originally
handled
Like the recent MEM_ATTRS changes, this patch is supposed to help the
transition to const_ints with modes. However, like those changes,
I think it makes sense on its own.
At the moment, the canonical way of testing a C condition in an
.md attribute is to use:
(ne (symbol_ref TEST)
Following on from the two patches I've just posted, this one makes
config/i386/*.md use match_test for .md attributes. Tested as
described here:

persmission for each one?
Preapproved for CRIS and MMIX.

While looking at 48370, I noticed that this bit of code in
initialize_reference really ought to be in grok_reference_init instead,
since it only applied to top-level references.
Tested x86_64-pc-linux-gnu, applied to trunk.
