Chad Rosier 30c0cb2f30 [ms-inline asm] Update for the MatchInstruction API change in r163101. 
llvm-svn: 163102
 2012-09-03 02:30:13 +00:00
Chad Rosier 6f0a9a2e2f Revert r162424 now that the scoping issue has been fixed in r162444.

Chad Rosier 7ae6360758 Tidy up. 
llvm-svn: 162786
 2012-08-28 20:35:06 +00:00
Chad Rosier 3dd7bf2c86 [ms-inline asm] Add constraints to MSAsmStmt. We don't currently compute 
the constraints, so in the interim we speculatively assume a 'r' constraint.
This is expected to work for most cases on x86.

Chad Rosier de70e0ef45 [ms-inline asm] As part of a larger refactoring, rename AsmStmt to GCCAsmStmt. 
No functional change intended.

llvm-svn: 162632
 2012-08-25 00:11:56 +00:00
Chad Rosier 175ea24e38 [ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a 
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.

Benjamin Kramer c5d00f61b6 Remove unnecessary calls to c_str. 
llvm-svn: 162590
 2012-08-24 20:43:21 +00:00
Chad Rosier 1e17cf9c22 [ms-inline asm] Generate the Input/Output expressions using 
Sema::ActOnIdExpression().

llvm-svn: 162564
 2012-08-24 16:38:58 +00:00
Chad Rosier ab24b6e24e Fix 80-column violation. 
llvm-svn: 162560
 2012-08-24 15:51:10 +00:00
Chad Rosier fe31e626ca [ms-inline asm] Add the basic APIs for Exprs to the MSAsmStmt AST. Next we need 
generate the Input/Output expressions using Sema::ActOnIdExpression().

llvm-svn: 162509
 2012-08-24 00:07:09 +00:00
Benjamin Kramer cc4c49dd63 Now that ASTMultiPtr is nothing more than a array reference, make it a MutableArrayRef. 
This required changing all get() calls to data() and using the simpler constructors.

Chad Rosier 8e0744312b [ms-inline asm] Rename a few induction variables to avoid confusion and silence 
a gcc warning.

llvm-svn: 162444
 2012-08-23 15:44:35 +00:00
Matt Beaumont-Gay 1e774bc835 Don't recycle loop variables (to keep GCC happy). 
llvm-svn: 162424
 2012-08-23 01:51:18 +00:00
Chad Rosier 0cf0615571 Fix 80-column violation. 
llvm-svn: 162416
 2012-08-23 00:12:51 +00:00
Chad Rosier f4958d1f10 [ms-inline asm] Compute the inputs and outputs. No test case (yet) as this 
requires codegen support.

llvm-svn: 162410
 2012-08-22 23:42:09 +00:00
Chad Rosier dc5311aab6 [ms-inline asm] Refactor code so that we can begin computing the Inputs/Outputs. 
No functional change intended.

Chad Rosier bb365caf80 [ms-inline asm] Add helper function. No functional change intended. 
llvm-svn: 162393

Chad Rosier 6b6a8a363b [ms-inline asm] Simplify logic. No functional change intended. 
llvm-svn: 162392
 2012-08-22 20:57:07 +00:00
Chad Rosier 060c0ea89a [ms-inline asm] Compute the token range for each instruction within the asm. 
Eventually, we'll need a way of mapping tokens (and their IdentifierInfo*) to
the operands computed by buildMSAsmPieces().

Chad Rosier a766697f4e [ms-inline asm] Simplify logic. No functional change intended.

 2012-08-22 19:50:28 +00:00
Chad Rosier d997bd1422 [ms-inline asm] Start sending non-simple inline asms to the AsmParser. 
The parser still can't handle all cases, so fall back to emitting a simple
MSAsmStmt if we get into trouble.

llvm-svn: 162382
 2012-08-22 19:18:30 +00:00
Chad Rosier bbdd467895 [ms-inline asm] Remove the patchMSAsmStrings function. After some discussion 
between Bob, Jim, Eric and I, we've decided to take a slightly different
approach.

llvm-svn: 162327
 2012-08-21 23:09:21 +00:00
Chad Rosier b958037958 [ms-inline asm] Have buildMSAsmString build a vector of unmodified AsmStrings. 
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
 2012-08-21 21:56:39 +00:00
Chad Rosier 5111f8650d [ms-inline asm] Do not report a Parser error when matching inline assembly. 
llvm-svn: 162307
 2012-08-21 19:37:55 +00:00
Chad Rosier 19160b6e39 [ms-inline asm] Expose the ErrorInfo from the MatchInstructionImpl. In general, 
this is the index of the operand that failed to match.

llvm-svn: 162296

Chad Rosier 5e80ced3f6 [ms-inline asm] Append identifier for better debugging.

Chad Rosier d4e55b8e35 [ms-inline asm] Remove old cruft now that MS-style asms their own code path. 
llvm-svn: 162210

Chad Rosier 571c5e91c4 [ms-inline asm] Update comment. 
llvm-svn: 162134
 2012-08-17 21:27:25 +00:00
Chad Rosier 0731affaca [ms-inline asm] Extract AsmStmt handling into a separate file, so as to not 
pollute SemaStmt with extraneous asm handling logic.
