* Prevent LiveRangeEdit from deleting bundled instructions.Andrew Trick2013-06-22
| | | | | | | | | We have no targets on trunk that bundle before regalloc. However, we have been advertising regalloc as bundle safe for use with out-of-tree targets. We need to at least contain the parts of the code that are still unsafe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184620 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Don't lose unreferenced non-trivial by-value parametersDavid Blaikie2013-06-21
| | | | | | | | | | | | A FastISel optimization was causing us to emit no information for such parameters & when they go missing we end up emitting a different function type. By avoiding that shortcut we not only get types correct (very important) but also location information (handy) - even if it's only live at the start of a function & may be clobbered later.

* Improve the time it takes to generating dwarf for assembly source filesKevin Enderby2013-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that have been run through the 'C' pre-processor. The implementation of SrcMgr.FindLineNumber() is slow but OK if it uses its cache when called multiple times with an SMLoc that is forward of the previous call. In the case of generating dwarf for assembly source files that have been run through the 'C' pre-processor we need to calculate the logical line number based on the last parsed cpp hash file line comment. And the current code calls SrcMgr.FindLineNumber() twice to do this causing its cache not to work and results in very slow compile times: % time /Volumes/SandBox/build-llvm/Debug+Asserts/bin/llvm-mc -triple thumbv7-apple-ios -filetype=obj -o /tmp/x.o mscorlib.dll.E -g 672.542u 0.299s 11:13.15 99.9% 0+0k 0+2io 2106pf+0w So we save the info from the last parsed cpp hash file line comment to avoid making the second call to SrcMgr.FindLineNumber() most times and end up with compile times like: % time /Volumes/SandBox/build-llvm/Debug+Asserts/bin/llvm-mc -triple thumbv7-apple-ios -filetype=obj -o /tmp/x.o mscorlib.dll.E -g 3.404u 0.104s 0:03.80 92.1% 0+0k 0+3io 2105pf+0w rdar://14156934 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184592 91177308-0d34-0410-b5e6-96231b3b80d8

* [PowerPC] Support R_PPC_REL16 family of relocationsUlrich Weigand2013-06-21
| | | | | | | | | | | | | The GNU assembler supports (as extension to the ABI) use of PC-relative relocations in half16 fields, which allows writing code like: li 1, base-.

* [yaml2obj][ELF] Don't explicitly set `Binding` with STB_*Sean Silva2013-06-21
| | | | | | | | | | | | | | | Instead, just have 3 sub-lists, one for each of {STB_LOCAL,STB_GLOBAL,STB_WEAK}. This allows us to be a lot more explicit w.r.t. the symbol ordering in the object file, because if we allowed explicitly setting the STB_* `Binding` key for the symbol, then we might have ended up having to shuffle STB_LOCAL symbols to the front of the list, which is likely to cause confusion and potential for error. Also, this new approach is simpler ;) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184506 91177308-0d34-0410-b5e6-96231b3b80d8

* Update the X86 disassembler to use xacquire and xrelease when appropriate.Kevin Enderby2013-06-20
| | | | | | | | | | | | | | | | | | This is a bit tricky as the xacquire and xrelease hints use the same bytes, 0xf2 and 0xf3, as the repne and rep prefixes. Fortunately llvm has different llvm MCInst Opcode enums for rep/xrelease and repne/xacquire. So to make this work a boolean was added the InternalInstruction struct as part of the Prefix state which is set with the added logic in readPrefixes() when decoding an instruction to determine if these prefix bytes are to be disassembled as xacquire or xrelease. Then we let the matcher pick the normal prefix instructionID and we change the Opcode after that when it is set into the MCInst being created. rdar://11019859 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184490 91177308-0d34-0410-b5e6-96231b3b80d8
