Evan Cheng 79a796c2b1 Fix PR2536: a nasty spiller bug. If a two-address instruction uses a register but the use portion of its live range is not part of its liveinterval, it must be defined by an implicit_def. In that case, do not spill the use. e.g. ... 8 %reg1024<def> = IMPLICIT_DEF 12 %reg1024<def> = INSERT_SUBREG %reg1024<kill>, %reg1025, 2 The live range [12, 14) are not part of the r1024 live interval since it's defined by an implicit def. It will not conflicts with live interval of r1025. Now suppose both registers are spilled, you can easily see a situation where both registers are reloaded before the INSERT_SUBREG and both target registers that would overlap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53503 91177308-0d34-0410-b5e6-96231b3b80d8		2008-07-12 01:56:02 +00:00
