Jim Grosbach	3e2c6f380c	ARM VLDR/VSTR instructions don't need a size suffix. ... Canonicallize on the non-suffixed form, but continue to accept assembly that has any correctly sized type suffix. llvm-svn: 144583	2011-11-14 23:03:21 +00:00

Evan Cheng	e891654a58	Change ARM / Thumb2 addc / adde and subc / sube modeling to use physical ... register dependency (rather than glue them together). This is general goodness as it gives scheduler more freedom. However it is motivated by a nasty bug in isel. When a i64 sub is expanded to subc + sube. libcall #1 \ \ subc \ / \ \ / \ \ / libcall #2 sube If the libcalls are not serialized (i.e. both have chains which are dag entry), legalizer can serialize them in arbitrary orders. If it's unlucky, it can force libcall #2 before libcall #1 in the above case. subc | libcall #2 | libcall #1 | sube However since subc and sube are "glued" together, this ends up being a cycle when the scheduler combine subc and sube as a single scheduling unit. The right solution is to fix LegalizeType too chains the libcalls together. However, LegalizeType is not processing nodes in order so that's harder than it should be. For now, the move to physical register dependency will do. rdar://10019576 llvm-svn: 138791	2011-08-30 01:34:54 +00:00
Rafael Espindola	29dda21e96	Remove arm_apcscc from the test files. It is the default and doing this ... matches what llvm-gcc and clang now produce. llvm-svn: 106221	2010-06-17 15:18:27 +00:00
