* Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo downEvan Cheng2011-07-18
| | | | | | | | | | to MCRegisterInfo. Also initialize the mapping at construction time. This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step towards fixing the layering violation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135424 91177308-0d34-0410-b5e6-96231b3b80d8

* From Kalle Raiskila:Chris Lattner2010-03-29
| | | | | | | | | | "the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions: -in vararg handling, registers are marked to be live, to not confuse the register scavenger -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99819 91177308-0d34-0410-b5e6-96231b3b80d8
* Change the Value argument to eliminateFrameIndex to a type-tagged value. ThisJim Grosbach2010-03-09
| | | | | | | | | | is preparatory to having PEI's scavenged frame index value reuse logic properly distinguish types of frame values (e.g., whether the value is stack-pointer relative or frame-pointer relative). No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98086 91177308-0d34-0410-b5e6-96231b3b80d8

* Large stack frame patch for the CellSPU: handle stack frames that exceed 8176Scott Michel2010-02-25
| | | | | | | | | | | | | | (511*16) bytes register displacement (D-form). NOTE: This is a potential headache, given the SPU's local core limitations, allowing the software developer to commit stack overrun suicide unknowingly. Also, large SPU stack frames will cause code size explosion. But, one presumes that the software developer knows what they're doing...

* Make the MachineFunction argument of getFrameRegister const.David Greene2009-11-12
| | | | | | | This also fixes a build error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87027 91177308-0d34-0410-b5e6-96231b3b80d8
* Add register-reuse to frame-index register scavenging. When a target usesJim Grosbach2009-10-07
| | | | | | | | | | | | | | | | | | | | | | a virtual register to eliminate a frame index, it can return that register and the constant stored there to PEI to track. When scavenging to allocate for those registers, PEI then tracks the last-used register and value, and if it is still available and matches the value for the next index, reuses the existing value rather and removes the re-materialization instructions. Fancier tracking and adjustment of scavenger allocations to keep more values live for longer is possible, but not yet implemented and would likely be better done via a different, less special-purpose, approach to the problem. eliminateFrameIndex() is modified so the target implementations can return the registers they wish to be tracked for reuse. ARM Thumb1 implements and utilizes the new mechanism. All other targets are simply modified to adjust for the changed eliminateFrameIndex() prototype. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83467 91177308-0d34-0410-b5e6-96231b3b80d8
