2007-08-07Long double patch 7 of N, unless I lost count:). Dale Johannesen
Last x87 bits for full functionality (not thoroughly tested, and long doubles do not work in SSE modes at all - use -mcpu=i486 for now) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40886 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-02Use 'static const char' instead of 'static const int'.Devang Patel
Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36652 91177308-0d34-0410-b5e6-96231b3b80d8

2006-11-02For PR786:Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-21Rewrite FP stackifier support in the X86InstrInfo.td file, splitting patternsChris Lattner
that were overloaded to work before and after the stackifier runs. With the new clean world, it is possible to write patterns for these instructions: woo! This also adds a few simple patterns here and there, though there are a lot still missing. These should be easy to add though. :) See the comments under "Floating Point Stack Support" for more details on the new world order. This patch as absolutely no effect on the generated code, woo! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24899 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-23Allow the FP stackifier to completely ignore functions that do not use FP atChris Lattner
all. This should speed up the X86 backend fairly significantly on integer codes. Now if only we didn't have to compute livevar still... ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19796 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-25Made a fix so that you can print out MachineInstrs that belong to a ↵Tanya Lattner
MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14389 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-11Now that compare instructions aren't lumped in with the other twoargfp ↵Chris Lattner

twoarg cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14143 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-11Split compare instruction handling OUT of handleTwoArgFP into handleCompareFP.Chris Lattner
This makes the code much simpler, and the two cases really do belong apart. Once we do it, it's pretty obvious how flawed the logic was for A != A case, so I fixed it (fixing PR369). This also uses freeStackSlotAfter instead of inserting an fxchg then popStackAfter'ing in the case where there is a dead result (unlikely, but possible), producing better code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14139 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-14This is the real fix for Codegen/X86/2004-04-13-FPCMOV-Crash.llx which worksChris Lattner
even when the "optimization" I added before is turned off. It generates this extremely pointless code: test: fld QWORD PTR [%ESP + 4] mov %AL, 0 test %AL, %AL fcmove %ST(0), %ST(0) ret Good thing the optimizer will have removed this before code generation anyway. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12939 91177308-0d34-0410-b5e6-96231b3b80d8
