* [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
| | | | llvm-svn: 165070
* [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] Enhance the isSimpleMSAsm() function to handle operands with ↵Chad Rosier2012-10-021-24/+26
| | | | | | | | pointer size directives (e.g., dword ptr [eax]). llvm-svn: 165031
* No need to call the InitializeAll* functions.Chad Rosier2012-10-021-5/+0
| | | | llvm-svn: 165025
* [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] Add $$ before numeric constants in the IR.Chad Rosier2012-09-111-8/+13

* [ms-inline asm] Output empty asm statements for the directives we don'tChad Rosier2012-09-061-10/+7
| | | | | | | handle. Otherwise, the AsmParser will explode if we try to generate an object files. llvm-svn: 163345
* [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
* Update for r163187.Chad Rosier2012-09-051-1/+1
| | | | llvm-svn: 163188
* [ms-inline asm] The MCInstrDesc only tracks register definitions. For now,Chad Rosier2012-09-041-1/+2
| | | | | | | assume that if the 1st operands is an expression and the instruction mayStore, then it is a memory definition. llvm-svn: 163144

* [ms-inline asm] Add constraints to MSAsmStmt. We don't currently computeChad Rosier2012-08-281-8/+23
| | | | | | | the constraints, so in the interim we speculatively assume a 'r' constraint. This is expected to work for most cases on x86. llvm-svn: 162784
* [ms-inline asm] As part of a larger refactoring, rename AsmStmt to GCCAsmStmt.Chad Rosier2012-08-251-13/+13
| | | | | | No functional change intended. llvm-svn: 162632
* [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

* [ms-inline asm] Compute the inputs and outputs. No test case (yet) as thisChad Rosier2012-08-221-1/+28
| | | | | | requires codegen support. llvm-svn: 162410
* [ms-inline asm] Refactor code so that we can begin computing the Inputs/Outputs.Chad Rosier2012-08-221-11/+19

* [ms-inline asm] Compute the token range for each instruction within the asm.Chad Rosier2012-08-221-4/+9
| | | | | | | Eventually, we'll need a way of mapping tokens (and their IdentifierInfo*) to the operands computed by buildMSAsmPieces(). llvm-svn: 162388
* [ms-inline asm] Simplify logic. No functional change intended.Chad Rosier2012-08-221-5/+11

* [ms-inline asm] Start sending non-simple inline asms to the AsmParser.Chad Rosier2012-08-221-15/+27
| | | | | | | The parser still can't handle all cases, so fall back to emitting a simple MSAsmStmt if we get into trouble. llvm-svn: 162382
* [ms-inline asm] Remove the patchMSAsmStrings function. After some discussionChad Rosier2012-08-211-134/+17
| | | | | | | between Bob, Jim, Eric and I, we've decided to take a slightly different approach. llvm-svn: 162327
* [ms-inline asm] Have buildMSAsmString build a vector of unmodified AsmStrings.Chad Rosier2012-08-211-7/+35
| | | | | | | | | | Add a new static function, buildMSAsmPieces, that will break these strings down into mnemonic and operands. Upon a match failure, the idea is to use the ErrorInfo from MatchInstructionImpl to inspect the mnemonic/operand and decide a course of action. Unfortunately, there's no easy way to test this at the moment. llvm-svn: 162321
