* - Tell PEI that PPC will handle stack frame rounding itself.Evan Cheng2007-01-251-7/+2
| | | | | | | - Do not round up to max. alignment of stack object if it is > stack alignment. It will have to be handled with dynamic aligning code. llvm-svn: 33505
* Repair debug frames as a prelude to eh_frames. Switched to using MachineMovesJim Laskey2007-01-241-15/+43
| | | | | | by value so that clean up is less confusing (these vectors tend to be small.) llvm-svn: 33488

* r13 is the thread pointer on darwin/ppc64, don't allocate it.Chris Lattner2006-11-201-2/+2

* 1. Ignore the -disable-fp-elim when the routine is a leaf.Jim Laskey2006-11-171-2/+2
| | | | | | 2. Offsets on 64-bit stores are still in bytes. llvm-svn: 31824
* This is a general clean up of the PowerPC ABI. Address several problems andJim Laskey2006-11-161-132/+244
| | | | | | | | | bugs including making sure that the TOS links back to the previous frame, that the maximum call frame size is not included twice when using frame pointers, no longer growing the frame on calls, double storing of SP and a cleaner/faster dynamic alloca. llvm-svn: 31792
* Fix ppc64 epilog bug.Chris Lattner2006-11-151-1/+1
| | | | llvm-svn: 31771
* Properly transfer kill / dead info.Evan Cheng2006-11-151-13/+17
| | | | llvm-svn: 31765
* Fix the PPC regressions last nightChris Lattner2006-11-151-6/+6
| | | | llvm-svn: 31752
* Rework PPC64 calls. Now we have a LR8/CTR8 register which the PPC64 callsChris Lattner2006-11-141-31/+51
| | | | | | | | clobber. This allows LR8 to be save/restored correctly as a 64-bit quantity, instead of handling it as a 32-bit quantity. This unbreaks ppc64 codegen when the code is actually located above the 4G boundary. llvm-svn: 31734
* Matches MachineInstr changes.Evan Cheng2006-11-131-10/+11
| | | | llvm-svn: 31712
* Make sure stack link is set in 64-bit.Jim Laskey2006-11-111-3/+9
| | | | llvm-svn: 31690
* implement proper PPC64 prolog/epilog codegen.Chris Lattner2006-11-111-30/+76
| | | | llvm-svn: 31684
* Running with frame pointers prevented debugging, external probes andJim Laskey2006-11-111-2/+5
| | | | | | | | potentially some system calls/exception handling from working. TOS must always link to previous frame. This is a short term workaround until alloca scheme is reworked. llvm-svn: 31677
* For PR786:Reid Spencer2006-11-021-1/+0
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380
* Completely eliminate def&use operands. Now a register operand is EITHER aChris Lattner2006-09-051-3/+3
| | | | | | def operand or a use operand. llvm-svn: 30109
* Handle callee saved registers in dwarf frame info (lead up to exceptionJim Laskey2006-08-291-6/+13
| | | | | | handling.) llvm-svn: 29954
* Fix some comments.Jim Laskey2006-08-251-1/+4
| | | | llvm-svn: 29880
* The PPC64 JIT needs register numbers to encode instructions.Chris Lattner2006-07-111-35/+36
| | | | llvm-svn: 29114
* In 64-bit mode, 64-bit GPRs are callee saved, not 32-bit ones.Chris Lattner2006-07-111-59/+94
| | | | llvm-svn: 29096
* Fix rewriting frame offsets with ixaddr instructions, which implicitly shiftChris Lattner2006-06-271-8/+21
| | | | | | the offset two bits to the left. llvm-svn: 28933
* Rename OR4 -> OR. Move some PPC64-specific stuff to the 64-bit fileChris Lattner2006-06-201-3/+3
| | | | llvm-svn: 28889
* Gaar! Don't use r11 for CR save/restore, use R0. R11 can be registerChris Lattner2006-06-121-9/+11
| | | | | | | | | | | | | | | | | | | allocated, thus live across the save/reload.
