2012-09-21[ms-inline asm] Use mnemonicIsValid() in a helpful assert.Chad Rosier
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164421 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163758 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-13[ms-inline asm] Handle the enumeration of input and output expressions in aChad Rosier
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163756 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-12[ms-inline asm] If we have a single asm operand that maps to multipleChad Rosier
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163728 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-06[ms-inline asm] The IR representation of inline assembly enumerates the inputChad Rosier
and output expressions much like that in GNU-style inline assembly. Output expressions are first. Do this for MS-style inline asms. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163342 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-04[ms-inline asm] The MCInstrDesc only tracks register definitions. For now,Chad Rosier
assume that if the 1st operands is an expression and the instruction mayStore, then it is a memory definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163144 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-28[ms-inline asm] Add constraints to MSAsmStmt. We don't currently computeChad Rosier
the constraints, so in the interim we speculatively assume a 'r' constraint. This is expected to work for most cases on x86. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162784 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-24[ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a Chad Rosier
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> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162602 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22[ms-inline asm] Compute the token range for each instruction within the asm.Chad Rosier
Eventually, we'll need a way of mapping tokens (and their IdentifierInfo*) to the operands computed by buildMSAsmPieces(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162388 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22[ms-inline asm] Start sending non-simple inline asms to the AsmParser.Chad Rosier
The parser still can't handle all cases, so fall back to emitting a simple MSAsmStmt if we get into trouble. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162382 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21[ms-inline asm] Remove the patchMSAsmStrings function. After some discussionChad Rosier
between Bob, Jim, Eric and I, we've decided to take a slightly different approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162327 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21[ms-inline asm] Have buildMSAsmString build a vector of unmodified AsmStrings.Chad Rosier
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162321 91177308-0d34-0410-b5e6-96231b3b80d8
