Chris Lattner 00ca0b8e98 start pushing MachinePointerInfo out through the MachineMemOperand interface 
to the MachineFunction construction methods.

llvm-svn: 114390
 2010-09-21 04:32:08 +00:00
Chris Lattner 187f653418 refactor the Value*/offset pair from MachineMemOperand out to a new 
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.

Chris Lattner bb0a1c44bf fix rdar://8453210, a crash handling a call through a GS relative load. 
For now, just disable folding the load into the call.

Evan Cheng f3e9a48584 Enable machine sinking critical edge splitting. e.g. 
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.

Owen Anderson 5e4734245d CombinerAA is now reordering these stores. 
llvm-svn: 114354
 2010-09-20 20:56:29 +00:00
Owen Anderson 272ff94916 When TCO is turned on, it is possible to end up with aliasing FrameIndex's. 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.

Jim Grosbach 94dfd6fc4f Simplify ARM callee-saved register handling by removing the distinction 
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

 2010-09-18 09:49:08 +00:00
Lang Hames cb1e1017dd Added a separate class (PBQPBuilder) for PBQP Problem construction. This 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.

Owen Anderson b92b13d8a0 Invert the logic of reachesChainWithoutSideEffects(). What we want to check 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".
