2011-07-14Fix typo in DEBUG message.Devang Patel

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135110 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-09Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng
CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08Eliminate asm parser's dependency on TargetMachine:Evan Cheng
- 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

2011-06-14Partial revert of 132882.Rafael Espindola
Dan noted that this would work on the case shown on the commit message. I think the case that was failing was a bb ending with a redundant conditional jump: ... jne foo foo: ... I was unable to find any such case in the tests or in a debug build of clang, so I will revert this part of the patch and watch the bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133004 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-10Ensure that EmitGlobalVariable is correctly differentiating between declarationsChad Rosier
and definitions when emitting global variables. This was causing global declarations to be emitted as if they were definitions. Fixes <rdar://problem/9429892>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132825 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-30Emit the handler's data area. For GCC-style exceptions under Win64, theCharles Davis
handler's data area starts with a 4-byte reference to the personality function, followed by the DWARF LSDA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132302 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-29When generating against the Win64 EH scheme, set the handler to the GCC-specificCharles Davis
handler. At this moment, only GCC-style exceptions are supported. Other kinds of exceptions, including "traditional" SEH and Microsoft Visual C++ exceptions, need more work--and an compiler exception model that isn't specific to GCC-style exceptions! In particular, I imagine that it would be possible to mix "traditional" SEH with GCC-style EH or Microsoft C++ EH. Currently LLVM has no way (beyond some target-specific defaults and whole-module compiler switches) of knowing which scheme to use when. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132283 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-28Fix the root cause of the bootstrap failure:Rafael Espindola
There was no way to check if a given register/mode pair was valid. We now return an error code (-2) instead of asserting. If anyone thinks that an assert at this point is really needed, we can autogen a hasValidDwarfRegNum instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132236 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Stub out support for Win64-style exceptions. Note that this is merely usingCharles Davis
the Win64 EH mechanism to implement GCC-style exceptions. LLVM supports hardly anything else at this point! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132234 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Fix a regression I recently introduced by removing DwarfRegNum ofRafael Espindola
subregisters: When a value is in a subregister, at least report the location as being the superregister. We should extend the .td files to encode the bit range so that we can produce a DW_OP_bit_piece. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132224 91177308-0d34-0410-b5e6-96231b3b80d8
