2010-09-21don't implicitly drop the offset of a machinememoperand when legalizing atomics.Chris Lattner

2010-09-21refactor the Value*/offset pair from MachineMemOperand out to a newChris Lattner
MachinePointerInfo struct, no functionality change. This also adds an assert to MachineMemOperand::MachineMemOperand that verifies that the Value* is either null or is an IR pointer type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114389 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-20Enable machine sinking critical edge splitting. e.g.Evan Cheng
define double @foo(double %x, double %y, i1 %c) nounwind { %a = fdiv double %x, 3.2 %z = select i1 %c, double %a, double %y ret double %z } Was: _foo: divsd LCPI0_0(%rip), %xmm0 testb $1, %dil jne LBB0_2 movaps %xmm1, %xmm0 LBB0_2: ret Now: _foo: testb $1, %dil je LBB0_2 divsd LCPI0_0(%rip), %xmm0 ret LBB0_2: movaps %xmm1, %xmm0 ret This avoids the divsd when early exit is taken. rdar://8454886 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114372 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20When TCO is turned on, it is possible to end up with aliasing FrameIndex's. ↵Owen Anderson
Therefore, CombinerAA cannot assume that different FrameIndex's never alias, but can instead use MachineFrameInfo to get the actual offsets of these slots and check for actual aliasing. This fixes CodeGen/X86/2010-02-19-TailCallRetAddrBug.ll and CodeGen/X86/tailcallstack64.ll when CombinerAA is enabled, modulo a different register allocation sequence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114348 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20Simplify ARM callee-saved register handling by removing the distinctionJim Grosbach
between the high and low registers for prologue/epilogue code. This was a Darwin-only thing that wasn't providing a realistic benefit anymore. Combining the save areas simplifies the compiler code and results in better ARM/Thumb2 codegen. For example, previously we would generate code like: push {r4, r5, r6, r7, lr} add r7, sp, #12 stmdb sp!, {r8, r10, r11} With this change, we combine the register saves and generate: push {r4, r5, r6, r7, r8, r10, r11, lr} add r7, sp, #12 rdar://8445635 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114340 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-18Added a separate class (PBQPBuilder) for PBQP Problem construction. This ↵Lang Hames
class can be extended to support custom constraints. For now the allocator still uses the old (internal) construction mechanism by default. This will be phased out soon assuming no issues with the builder system come up. To invoke the new construction mechanism just pass '-regalloc=pbqp -pbqp-builder' to llc. To provide custom constraints a Target just needs to extend PBQPBuilder and pass an instance of their derived builder to the RegAllocPBQP constructor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114272 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-18Invert the logic of reachesChainWithoutSideEffects(). What we want to check ↵Owen Anderson
is that there is NO path to the destination containing side effects, not that SOME path contains no side effects. In practice, this only manifests with CombinerAA enabled, because otherwise the chain has little to no branching, so "any" is effectively equivalent to "all". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114268 91177308-0d34-0410-b5e6-96231b3b80d8
