2012-10-23Make branch heavy code for generating marked up disassembly simplerKevin Enderby
and easier to read by adding a couple helper functions. Suggestion by Chandler Carruth and seconded by Meador Inge! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166515 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-22Add support for annotated disassembly output for X86 and arm.Kevin Enderby
Per the October 12, 2012 Proposal for annotated disassembly output sent out by Jim Grosbach this set of changes implements this for X86 and arm. The llvm-mc tool now has a -mdis option to produced the marked up disassembly and a couple of small example test cases have been added. rdar://11764962 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166445 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-22[ms-inline asm] Don't rewrite out parts of an inline-asm skipped by .if 0 ↵Eli Friedman
and friends. It's unnecessary and makes the generated assembly less faithful to the original source. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166440 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-19[ms-inline asm] Have the TargetParser callback to Sema to determine the size ofChad Rosier
a memory operand. Retain this information and then add the sizing directives to the IR. This allows the backend to do proper instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166316 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-18[ms-inline asm] Add a size argument to the LookupInlineAsmIdentifier() callback,Chad Rosier
which will be used by the asm matcher in the near future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166222 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-18[ms-inline asm] Have the LookupInlineAsmIdentifier() callback function return aChad Rosier
*NamedDecl. In turn, build the expressions after we're finished parsing the asm. This avoids a crasher if the lookup fails. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166212 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-18[ms-inline asm] Move most of the AsmParsing logic in clang back into the MCChad Rosier
layer. Add the ParseMSInlineAsm() function, which is the new interface to clang. Also expose the new MCAsmParserSemaCallback interface, which is used by the back-end to do name lookup in Sema. Finally, remove the now defunct APIs introduced in r165946. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166183 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-15[ms-inline asm] Add a few new APIs to the AsmParser class in support of MS-StyleChad Rosier
inline assembly. For the time being, these will be called directly by clang. However, in the near future I expect these to be sunk back into the MC layer and more basic APIs (e.g., getClobbers(), getConstraints(), etc.) will be called by clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165946 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-15PowerPC: add EmitTCEntry class for TOC creationAdhemerval Zanella
This patch replaces the EmitRawText by a EmitTCEntry class (specialized for each Streamer) in PowerPC64 TOC entry creation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165940 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-13[ms-inline asm] Remove the MatchInstruction() function. Previously, this wasChad Rosier
the interface between the front-end and the MC layer when parsing inline assembly. Unfortunately, this is too deep into the parsing stack. Specifically, we're unable to handle target-independent assembly (i.e., assembly directives, labels, etc.). Note the MatchAndEmitInstruction() isn't the correct abstraction either. I'll be exposing target-independent hooks shortly, so this is really just a cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165858 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-02Support for generating ELF objects on Windows.Andrew Kaylor
