2013-01-16Now that GenericAsmParser was folded into AsmParser, some methods and types canEli Bendersky

2013-01-16We want the dwarf AT_producer for assembly source files to match clang'sKevin Enderby
AT_producer. Which includes clang's version information so we can tell which version of the compiler was used. This is the first of two steps to allow us to do that. This is the llvm-mc change to provide a method to set the AT_producer string. The second step, coming soon to a clang near you, will have the clang driver pass the value of getClangFullVersion() via an flag when invoking the integrated assembler on assembly source files. rdar://12955296 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172630 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-15Split address information for DWARF5 split dwarf proposal. This involvesEric Christopher
using the DW_FORM_GNU_addr_index and a separate .debug_addr section which stays in the executable and is fully linked. Sneak in two other small changes: a) Print out the debug_str_offsets.dwo section. b) Change form we're expecting the entries in the debug_str_offsets.dwo section to take from ULEB128 to U32. Add tests for all of this in the fission-cu.ll test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172578 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Optimize the memory usage of MC bundling, by creating a new type of fragmentEli Bendersky
into which we can emit single instructions without fixups (which is most instructions). This is an optimization required because MCDataFragment is prety large (240 bytes on x64), with no change in functionality. For large programs, this reduces memory usage overhead required for bundling by 40%. To make the code as palatable as possible, the MCEncodedFragment interface was further fragmented (no pun intended) and MCEncodedFragmentWithFixups is used as the interface to work against when the user expects fixups. MCDataFragment and MCRelaxableFragment implement this interface, while the new MCCompactEncodedInstFragment implements MCEncodeFragment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172572 91177308-0d34-0410-b5e6-96231b3b80d8

Specifically, clang/test/CodeGen/ms-inline-asm.c t15(), t16(), and t24(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172569 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Refactor generic Asm directive parsing.Eli Bendersky
After discussing the refactoring with Jim and Daniel, the following changes were made: * All generic directive parsing is now done by AsmParser itself. The previous division between it and GenericAsmParser did not have clear boundaries and just produced unnatural code of GenericAsmParser juggling the internals of AsmParser through an interface. The division of responsibilities is now clear: target-specific directives, other extensions (used by platform-specific parseres), and generic directives. * Priority for directive parsing was reshuffled to ask extensions first and check the generic directives later. No change in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172568 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Now GenericAsmParser and AsmParser are no longer friends, GenericAsmParser canEli Bendersky
simply use the getParser method from MCAsmParserExtension, working through the MCAsmParser interface. There's no longer a need to overload that method to cast it to the concrete AsmParser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172491 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Properly encapsulate additional methods and data from AsmParser.Eli Bendersky
This finally allows AsmParser to no longer list GenericAsmParser as a friend. All member vars directly accessed by GenericAsmParser have been properly encapsulated and exposed through the MCAsmParser interface. This reduces the coupling between AsmParser and GenericAsmParser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172490 91177308-0d34-0410-b5e6-96231b3b80d8
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

2013-01-12Make 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
2013-01-11Proof of concept moving of generic directive parsing from AsmParser to theEli Bendersky

This patch adjust the r171506 to make all DWARF enconding pc-relative for PPC64.
