git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72903 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Specify that this works for Darwin.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72899 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04The DWARF unwind info was incorrect. While compiling withBill Wendling
`-fomit-frame-pointer', we would lack the DW_CFA_advance_loc information for a lot of function, and then they would be `0'. The linker (at least on Darwin) needs to encode the stack size. In some cases, the stack size is too large to directly encode. So the linker checks to see if there is a "subl $xxx,%esp" instruction at the point where the `DW_CFA_def_cfa_offset' says the pc was. If so, the compact encoding records the offset in the function to where the stack size is embedded. But because the `DW_CFA_advance_loc' instructions are missing, it looks before the function and dies. So, instead of emitting the EH debug label before the stack adjustment operations, emit it afterwards, right before the frame move stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72898 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Add new function attribute - noredzone. Devang Patel
Update code generator to use this attribute and remove DisableRedZone target option. Update llc to set this attribute when -disable-red-zone command line option is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72894 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Fix FP_TO_UINT->i32 on ppc32 -mcpu=g5. This wasDale Johannesen
using Promote which won't work because i64 isn't a legal type. It's easy enough to use Custom, but then we have the problem that when the type legalizer is promoting FP_TO_UINT->i16, it has no way of telling it should prefer FP_TO_SINT->i32 to FP_TO_UINT->i32. I have uncomfortably hacked this by making the type legalizer choose FP_TO_SINT when both are Custom. This fixes several regressions in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72891 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-04Don't do the X * 0.0 -> 0.0 transformation in instcombine, becauseDan Gohman
instcombine doesn't know when it's safe. To partially compensate for this, introduce new code to do this transformation in dagcombine, which can use UnsafeFPMath. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72872 91177308-0d34-0410-b5e6-96231b3b80d8

assembler Add lto_codegen_set_assembler_path() API which allows the linker to specify the path to the assembler tool to run. When assembler is used (instead of compiler) different command line options are used. Add LTO_API_VERSION #define so clients (linkers) can conditionalize use of new APIs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72823 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-03Change LTO to run the global opt pass twice.Daniel Dunbar
- This matches llvm-ld. It took a bit of archeology to figure out what the right thing to do was (whether this was intentionally added or intentionally removed). My final conclusion is that Chris added this intentionally here: http://llvm.org/viewvc/llvm-project?view=rev&revision=16913 but the changes weren't propogated to llvm-ld until here: http://llvm.org/viewvc/llvm-project?view=rev&revision=34058 which was after lto.cpp had been cloned off (of llvm-ld), here: http://llvm.org/viewvc/llvm-project?view=rev&revision=29494 From the commit message, it looks like the motivation for running global opt again is because we ran it prior to inlining. Based on that I updated the comment and also only run the pass if we actually ran the inliner. Chris, please review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72811 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-03For Darwin / x86_64, override -relocation-model=static to pic if the output ↵Evan Cheng
is assembly since Darwin assembler does not really support -static codeine. I view this as a temporary workaround until the assembler / linker changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72806 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Add createStandardLTOPasses to StandardPasses.h, and move lto and llvm-ld over.Daniel Dunbar
- I know it sounds crazy, but I think all the pass lists are now coalesced into StandardPasses.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72805 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Convert Alpha and Mips to use a MachineFunctionInfo subclass toDan Gohman
carry GlobalBaseReg, and GlobalRetAddr too in Alpha's case. This eliminates the need for them to search through the MachineRegisterInfo livein list in order to identify these virtual registers. EmitLiveInCopies is now the only user of the virtual register portion of MachineRegisterInfo's livein data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72802 91177308-0d34-0410-b5e6-96231b3b80d8
