* Encapsulate the MacroEnabled flag in AsmParser behind accessor methods.Eli Bendersky2013-01-141-4/+7
| | | | | | | | The methods are also exposed via the MCAsmParser interface, which allows more than one client to control them. Previously, GenericAsmParser was playing with a member var in AsmParser directly (by virtue of being its friend). llvm-svn: 172440
* Stop hiding the interface-exposed EatToEndOfStatement (see r172276).Eli Bendersky2013-01-121-2/+1

* Make ParseIdentifier a public method instead of private.Eli Bendersky2013-01-121-4/+4
| | | | | | | | | | | | | | | | | The MCAsmParser interface defines ParseIdentifier is public. There's no reason whatsoever for AsmParser (which implements the MCAsmParser interface) to hide this method. This is all part of a bigger scheme. Several asm parsing "extensions" use the main parser properly through the MCAsmParser interface. However, GenericAsmParser has much more exclusive access and uses implementation details from the concrete implementation - AsmParser, in which it is also declared as a friend. This makes for overly coupled code, and even makes it hard to split GenericAsmParser into a separate file. There's no reason why GenericAsmParser shouldn't be able to access AsmParser through an abstract interface, as long as it's actually registered as an extension. llvm-svn: 172276
* Proof of concept moving of generic directive parsing from AsmParser to theEli Bendersky2013-01-111-41/+38
| | | | | | | | GenericAsmParser extension, where a lot of directives are already being parsed. The end goal is having just a single place (and a single lookup table) for all directive parsing. llvm-svn: 172268

* Change SMRange to be half-open (exclusive end) instead of closed (inclusive)Jordan Rose2013-01-071-10/+11
| | | | | | | | | | This is necessary not only for representing empty ranges, but for handling multibyte characters in the input. (If the end pointer in a range refers to a multibyte character, should it point to the beginning or the end of the character in a char array?) Some of the code in the asm parsers was already assuming this anyway. llvm-svn: 171765
* Aligned bundling support. Following the discussion here:Eli Bendersky2012-12-201-0/+67
| | | | | | | | | | | http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056754.html The proposal and implementation are fully documented here: https://sites.google.com/a/chromium.org/dev/nativeclient/pnacl/aligned-bundling-support-in-llvm Tests will follow shortly. llvm-svn: 170718

* [ms-inline asm] Make sure we fail gracefully on parse errors. Parse errorsChad Rosier2012-12-121-2/+9
| | | | | | | | should only occur on invalid input. Instruction matching errors aren't unexpected, so we can't rely on the AsmParsers HadError variable directly. rdar://12840278 llvm-svn: 170037
* MC/AsmParser: Avoid unnecessary use of SourceMgr::FindBufferForLoc()Daniel Dunbar2012-12-011-7/+21
| | | | | | | | - Each macro instantiation introduces a new buffer, and FindBufferForLoc() is linear, so previously macro instantiation could be N^2 for some pathological inputs. llvm-svn: 169073

* [ms-inline asm] Create a register operand, rather than a memory operand when weChad Rosier2012-10-241-2/+2
| | | | | | | | | | see the offsetof operator. Previously, we were matching something like MOVrm in the front-end and later matching MOVrr in the back-end. This change makes things more consistent. It also fixes cases where we can't match against a memory operand as the source (test cases coming). Part of rdar://12470317 llvm-svn: 166592

* [ms-inline asm] Move most of the AsmParsing logic in clang back into the MCChad Rosier2012-10-181-18/+201
| | | | | | | | | 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. llvm-svn: 166183

* [ms-inline asm] Add a few new APIs to the AsmParser class in support of MS-StyleChad Rosier2012-10-151-13/+34
| | | | | | | | | 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. llvm-svn: 165946
* [ms-inline asm] Remove the MatchInstruction() function. Previously, this wasChad Rosier2012-10-131-5/+15
| | | | | | | | | | | 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. llvm-svn: 165858
