* implement rdar://6653118 - fastisel should fold loads where possible.Chris Lattner2010-09-051-3/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113102 91177308-0d34-0410-b5e6-96231b3b80d8
* Change LEA to have 5 operands for its memory operand, justChris Lattner2010-07-081-26/+13
| | | | | | | | | | | | like all other instructions, even though a segment is not allowed. This resolves a bunch of gross hacks in the encoder and makes LEA more consistent with the rest of the instruction set.

* Improve MachineMemOperand handling.Dan Gohman2009-09-251-5/+6
| | | | | | | | | | | | | | | | | | | | | | - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8

* Change MachineInstrBuilder::addReg() to take a flag instead of a list ofBill Wendling2009-05-131-4/+4
| | | | | | | | | | | | | booleans. This gives a better indication of what the "addReg()" is doing. Remembering what all of those booleans mean isn't easy, especially if you aren't spending all of your time in that code. I took Jakob's suggestion and made it illegal to pass in "true" for the flag. This should hopefully prevent any unintended misuse of this (by reverting to the old way of using addReg()). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71722 91177308-0d34-0410-b5e6-96231b3b80d8
