2012-11-28Move the guts of TargetInstrInfoImpl into the TargetInstrInfo class.Jakob Stoklund Olesen
The *Impl class no longer serves a purpose now that the super-class implementation is in CodeGen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168759 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-28Move Target{Instr,Register}Info.cpp into lib/CodeGen.Jakob Stoklund Olesen
The Target library is not allowed to depend on the large CodeGen library, but the TRI and TII classes provide abstract interfaces that require both caller and callee to link to CodeGen. The implementation files for these classes provide default implementations of some of the hooks. These methods may need to reference CodeGen, so they belong in that library. We already have a number of methods implemented in the TargetInstrInfoImpl sub-class because of that. I will merge that class into the parent next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168758 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-27CSE: allow PerformTrivialCoalescing to check copies across basic blockManman Ren
boundaries. Given the following case: BB0 %vreg1<def> = SUBrr %vreg0, %vreg7 %vreg2<def> = COPY %vreg7 BB1 %vreg10<def> = SUBrr %vreg0, %vreg2 We should be able to CSE between SUBrr in BB0 and SUBrr in BB1. rdar://12462006 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168717 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-27Remove duplicated #includes.Jakub Staszak
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168712 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-27Never use .lcomm on platforms where it does not accept an alignmentUlrich Weigand
argument. Instead, use a pair of .local and .comm directives. This avoids spurious differences between binaries built by the integrated assembler vs. those built by the external assembler, since the external assembler may impose alignment requirements on .lcomm symbols where the integrated assembler does not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168704 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-26Now that the X86 Maximal Stack Alignment Check pass has been removed (i.e.,Chad Rosier
r168627), we no longer need to call the freezeReservedRegs() function a second time. Previously, this pass was conservatively adding the FP to the set of reserved registers, requiring the second update to the reserved registers. rdar://12719844 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168631 91177308-0d34-0410-b5e6-96231b3b80d8
