* implement rdar://6653118 - fastisel should fold loads where possible.Chris Lattner2010-09-054-10/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since mem2reg isn't run at -O0, we get a ton of reloads from the stack, for example, before, this code: int foo(int x, int y, int z) { return x+y+z; } used to compile into: _foo: ## @foo subq $12, %rsp movl %edi, 8(%rsp) movl %esi, 4(%rsp) movl %edx, (%rsp) movl 8(%rsp), %edx movl 4(%rsp), %esi addl %edx, %esi movl (%rsp), %edx addl %esi, %edx movl %edx, %eax addq $12, %rsp ret Now we produce: _foo: ## @foo subq $12, %rsp movl %edi, 8(%rsp) movl %esi, 4(%rsp) movl %edx, (%rsp) movl 8(%rsp), %edx addl 4(%rsp), %edx ## Folded load addl (%rsp), %edx ## Folded load movl %edx, %eax addq $12, %rsp ret Fewer instructions and less register use = faster compiles. llvm-svn: 113102

* Disable the asserts that check that normalization is perfectlyDan Gohman2010-09-031-2/+7
| | | | | | | | | invertible. ScalarEvolution's folding routines don't always succeed in canonicalizing equal expressions to a single canonical form, and this can cause these asserts to fail, even though there's no actual correctness problem. This fixes PR8066. llvm-svn: 113021

* Re-apply r112883:Jim Grosbach2010-09-033-26/+95
| | | | | | | | | | | | | | "For ARM stack frames that utilize variable sized objects and have either large local stack areas or require dynamic stack realignment, allocate a base register via which to access the local frame. This allows efficient access to frame indices not accessible via the FP (either due to being out of range or due to dynamic realignment) or the SP (due to variable sized object allocation). In particular, this greatly improves efficiency of access to spill slots in Thumb functions which contain VLAs." r112986 fixed a latent bug exposed by the above. llvm-svn: 112989
* VirtRegRewriter checks for early clobbers before it reuses an available stackJakob Stoklund Olesen2010-09-031-5/+7
| | | | | | | | | | | | slot. Teach it to also check for early clobbered aliases, and early clobber operands following the current operand. This fixes the miscompilation in PR8044 where EC registers eax and ecx were being used for inputs. llvm-svn: 112988
* Check the local frame alignment for determining whether dynamic stackJim Grosbach2010-09-031-1/+1
| | | | | | | | | alignment should be performed. Otherwise dynamic realignment may trigger when the register allocator has already used the frame pointer as a general purpose register. That is, we need to make sure that the list of reserved registers doesn't change after register allocation. llvm-svn: 112986
* Finish converting the rest of the NEON VLD instructions to use pseudo-Bob Wilson2010-09-034-154/+149
| | | | | | | | | instructions prior to regalloc. Since it's getting a little close to the 2.8 branch deadline, I'll have to leave the rest of the instructions handled by the NEONPreAllocPass for now, but I didn't want to leave half of the VLD instructions converted and the other half not. llvm-svn: 112983
