Evan Cheng 342e3161d9 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138791 91177308-0d34-0410-b5e6-96231b3b80d8		2011-08-30 01:34:54 +00:00
