Jakob Stoklund Olesen 9390cd0e86 Remove RegisterScavenger::isSuperRegUsed(). This completely reverses the mistaken commit r77904. ... Now there is no special treatment of instructions that redefine part of a super-register. Instead, the super-register is marked with <imp-use,kill> and <imp-def>. For instance, from LowerSubregs on ARM: subreg: CONVERTING: %Q1<def> = INSERT_SUBREG %Q1<undef>, %D1<kill>, 5 subreg: %D2<def> = FCPYD %D1<kill>, 14, %reg0, %Q1<imp-def> subreg: CONVERTING: %Q1<def> = INSERT_SUBREG %Q1, %D0<kill>, 6 subreg: %D3<def> = FCPYD %D0<kill>, 14, %reg0, %Q1<imp-use,kill>, %Q1<imp-def> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78466 91177308-0d34-0410-b5e6-96231b3b80d8		2009-08-08 13:19:10 +00:00
