* [ms-inline asm] Add a size argument to the LookupInlineAsmIdentifier() callback,Chad Rosier2012-10-181-3/+8

| | | | | | | *NamedDecl. In turn, build the expressions after we're finished parsing the asm. This avoids a crasher if the lookup fails. llvm-svn: 166213
* [ms-inline asm] Move most of the AsmParsing logic in clang back into the MCChad Rosier2012-10-181-180/+81
| | | | | | | layer. Use the new ParseMSInlineAsm() API and add an implementation of the MCAsmParserSemaCallback interface. llvm-svn: 166184
* [ms-inline asm] Move some logic around to simplify the interface between theChad Rosier2012-10-161-18/+32
| | | | | | front-end and the AsmParser. No functional change intended. llvm-svn: 166063
* [ms-inline asm] Rework the front-end to use the API introduced in r165946.Chad Rosier2012-10-151-217/+179
| | | | | | | | | | | | | | | | | | | -The front-end now builds a single assembly string and feeds it to the AsmParser. The front-end iterates on a per statement basis by calling the ParseStatement() function. Please note, the calling of ParseStatement() and and any notion of MCAsmParsedOperands will be sunk into the MC layer in the near future. I plan to expose more basic APIs such as getClobbers, etc. -The enumeration of the AsmString expressions have been reworked to use SMLocs rather than assembly Pieces, which were being parsed in the front-end. -The test case, t8(), was modified due to r129223. I'll have to find a way to work around things such as these. Sorry for the large commit, but breaking this in multiple smaller commits proved too irritating. llvm-svn: 165957

* [ms-inline asm] Lookup the IdentifierInfo using the Idents table and remove theChad Rosier2012-10-111-17/+1
| | | | | | | | | now unused static helper function. The test case needs to be remove temporarily until I can better filter memory operands that aren't actual variable reference. llvm-svn: 165751
* Revert 165058, per Jim request. This requires further discussion.Chad Rosier2012-10-021-38/+2

* [ms-inline asm] Rewrite the symbol references as wildcard MCParsedAsmOperands.Chad Rosier2012-10-021-2/+38
| | | | | | | A Sema lookup is used to determine the size of the variable, which is in turn used during wildcard matching. llvm-svn: 165058

* [ms-inline asm] Use the convertToMapAndConstraints() function in the front-end.Chad Rosier2012-10-011-62/+72
| | | | | | Rework the logic to account for the fact that we no longer create a MCInst. llvm-svn: 164980
* Examine the last, not the first, instruction from the MC matcher.Bob Wilson2012-09-251-1/+1
| | | | | | | | If an MS-style inline asm is matched to multiple instructions, e.g., with a a WAIT-prefix, then we need to examine the operands of the last instruction instruction, not the prefix instruction. llvm-svn: 164608
* Update for r164567.Chad Rosier2012-09-241-2/+2
| | | | llvm-svn: 164568

* [ms-inline asm] Handle the enumeration of input and output expressions in aChad Rosier2012-09-131-35/+105
| | | | | | | | | | | | more robust way to address a few FIXMEs. The initial implementation, r163342, built the IR asm string and then tried to patch things on the fly without enough context. Specifically, it didn't skip mnemonics nor did it track with assembly instruction an expression was related to. The new implementation patches the operands and then builds the final IR string. llvm-svn: 163756
* [ms-inline asm] If we have a single asm operand that maps to multipleChad Rosier2012-09-121-55/+53
| | | | | | | | | | | MCOperands then iterate over all of then when computing clobbers, inputs and outputs. On x86 the 1-to-many mapping is a memory operand that includes a BaseReg(reg), MemScale(imm), MemIndexReg(reg), an Expr(MCExpr or imm) and a MemSegReg(reg). Invalid register (Op.getReg() == 0) are not considered when computing clobber. llvm-svn: 163728

* [ms-inline asm] Output empty asm statements for the directives we don'tChad Rosier2012-09-061-10/+7

* [ms-inline asm] The IR representation of inline assembly enumerates the inputChad Rosier2012-09-061-0/+25
| | | | | | | and output expressions much like that in GNU-style inline assembly. Output expressions are first. Do this for MS-style inline asms. llvm-svn: 163342

* [ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a Chad Rosier2012-08-241-2/+0
| | | | | | | | | CodeGen option to a LangOpt option. In turn, hoist the guard into the parser so that we avoid the new (and fairly unstable) Sema/AST/CodeGen logic. This should restore the behavior of clang to that prior to r158325. <rdar://problem/12163681> llvm-svn: 162602
