2013-01-14Move CheckForValidSection to the MCAsmParser interface.Eli Bendersky
Now that it behaves itself in terms of streamer independence (r172450), this method can be moved to MCAsmParser to be available to all extensions, overriding, etc. -- -This line, and those below, will be ignored-- M lib/MC/MCParser/AsmParser.cpp M include/llvm/MC/MCParser/MCAsmParser.h git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172451 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Expose an InitToTextSection through MCStreamer.Eli Bendersky
The aim of this patch is to fix the following piece of code in the platform-independent AsmParser: void AsmParser::CheckForValidSection() { if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) { TokError("expected section directive before assembly directive"); Out.SwitchSection(Ctx.getMachOSection( "__TEXT", "__text", MCSectionMachO::S_ATTR_PURE_INSTRUCTIONS, 0, SectionKind::getText())); } } This was added for the "-n" option of llvm-mc. The proposed fix adds another virtual method to MCStreamer, called InitToTextSection. Conceptually, it's similar to the existing InitSections which initializes all common sections and switches to text. The new method is implemented by each platform streamer in a way that it sees fit. So AsmParser can now do this: void AsmParser::CheckForValidSection() { if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) { TokError("expected section directive before assembly directive"); Out.InitToTextSection(); } } Which is much more reasonable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172450 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Move ParseMacroArgument to the MCAsmParser interfance.Eli Bendersky
Since it's used by extensions. One further step to fully decoupling GenericAsmParser from an intimate knowledge of the internals of AsmParser, pointing it to the MCASmParser interface instead (like all other parser extensions do). Since this change moves the MacroArgument type to the interface header, it's renamed to be a bit more descriptive in a general context. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172449 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Encapsulate the MacroEnabled flag in AsmParser behind accessor methods.Eli Bendersky
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172440 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-12Fixed bug in ObjCARC where we were changing a call from objc_autoreleaseRV ↵Michael Gottesman

2013-01-12Fixed a bug where we were tail calling objc_autorelease causing an object to ↵Michael Gottesman
not be placed into an autorelease pool. The reason that this occurs is that tail calling objc_autorelease eventually tail calls -[NSObject autorelease] which supports fast autorelease. This can cause us to violate the semantic gaurantees of __autoreleasing variables that assignment to an __autoreleasing variables always yields an object that is placed into the innermost autorelease pool. The fix included in this patch works by: 1. In the peephole optimization function OptimizeIndividualFunctions, always remove tail call from objc_autorelease. 2. Whenever we convert to/from an objc_autorelease, set/unset the tail call keyword as appropriate. *NOTE* I also handled the case where objc_autorelease is converted in OptimizeReturns to an autoreleaseRV which still violates the ARC semantics. I will be removing that in a later patch and I wanted to make sure that the tree is in a consistent state vis-a-vis ARC always. Additionally some test cases are provided and all tests that have tail call marked objc_autorelease keywords have been modified so that tail call has been removed. *NOTE* One test fails due to a separate bug that I am going to commit soon. Thus I marked the check line TMP: instead of CHECK: so make check does not fail. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172287 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-12This patch tackles the problem of parsing Mips Jack Carter
register names in the standalone assembler llvm-mc. Registers such as $A1 can represent either a 32 or 64 bit register based on the instruction using it. In addition, based on the abi, $T0 can represent different 32 bit registers. The problem is resolved by the Mips specific AsmParser td definitions changing to work together. Many cases of RegisterClass parameters are now RegisterOperand. Contributer: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172284 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-12Make ParseIdentifier a public method instead of private.Eli Bendersky
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172276 91177308-0d34-0410-b5e6-96231b3b80d8
