* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-08
| | | | | | | | | | | - Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow x87 FP registers to be alive globally in a function.Jakob Stoklund Olesen2010-07-16
| | | | | | | | | | | | | | | | FP_REG_KILL instructions are still inserted, but can be disabled by passing -live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly. CFG edges are partioned into bundles where the x87 stack must be allocated identically. Code is insertad at the end of each basic block that shuffles the live FP registers to match the outgoing bundles expectations. This fix is in preparation for some upcoming register allocator improvements that may extend the live range of registers beyond a basic block, similar to LICM. It also provides a nice runtime speedup if you are building with -mfpmath=387. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108529 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR6696 and PR6663Jim Grosbach2010-04-06
| | | | | | | | | | | | | | | | | | | When a frame pointer is not otherwise required, and dynamic stack alignment is necessary solely due to the spilling of a register with larger alignment requirements than the default stack alignment, the frame pointer can be both used as a general purpose register and a frame pointer. That goes poorly, for obvious reasons. This patch brings back a bit of old logic for identifying the use of such registers and conservatively reserves the frame pointer during register allocation in such cases. For now, implement for X86 only since it's 32-bit linux which is hitting this, and we want a targeted fix for 2.7. As a follow-on, this will be expanded to handle other targets, as theoretically the problem could arise elsewhere as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100559 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain ↵Jakob Stoklund Olesen2010-03-25
| | | | | | | | | | | | | | | | | | | | | | crossings. On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register in a different domain than where it was defined. Some instructions have equvivalents for different domains, like por/orps/orpd. The SSEDomainFix pass tries to minimize the number of domain crossings by changing between equvivalent opcodes where possible. This is a work in progress, in particular the pass doesn't do anything yet. SSE instructions are tagged with their execution domain in TableGen using the last two bits of TSFlags. Note that not all instructions are tagged correctly. Life just isn't that simple. The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline issue handled by NEONMoveFixPass. This pass may become target independent to handle both. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99524 91177308-0d34-0410-b5e6-96231b3b80d8
