* default construct MCInst's ctor to 0, which is "PHI" which is invalid for ↵Chris Lattner2009-09-11

* MC: Give target specific parsers access to the MCStreamer.Daniel Dunbar2009-09-10
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81416 91177308-0d34-0410-b5e6-96231b3b80d8
* remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner2009-09-09
| | | | | | | | | | | | | | | the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8
* Added an abstract superclass, MCDisassembler, forSean Callanan2009-09-09
| | | | | | | | | | | | | | all disassemblers. Modified the MemoryObject to support 64-bit address spaces, regardless of the LLVM process's address width. Modified the Target class to allow extraction of a MCDisassembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81392 91177308-0d34-0410-b5e6-96231b3b80d8

* Added AsmToken enum constants to MCAsmLexer.h for '[', ']', '{', and '}' inKevin Enderby2009-09-04
| | | | | | | | preparation of supporting other targets. Then changed the lexer to parse these as tokens. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81050 91177308-0d34-0410-b5e6-96231b3b80d8
* Added the AsmToken::Hash enum constant to MCAsmLexer.h in preparation ofKevin Enderby2009-09-04
| | | | | | | | | supporting other targets. Changed the code to pass MCAsmInfo to the parser and the lexer. Then changed the lexer to use CommentString from MCAsmInfo instead of a literal '#' character. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81046 91177308-0d34-0410-b5e6-96231b3b80d8
* Removed the non-target independent AsmToken::Register enum constantKevin Enderby2009-09-03
| | | | | | | | | | | from MCAsmLexer.h in preparation of supporting other targets. Changed the X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking for AsmToken::Percent when parsing in places that used AsmToken::Register. Then changed X86ATTAsmParser::ParseRegister to parse out registers as an AsmToken::Percent followed by an AsmToken::Identifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80929 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Support .zerofill emission.Daniel Dunbar2009-08-28
| | | | | | - I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80347 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc/Mach-O: Add MCCodeEmitter support, for encoding instructions.Daniel Dunbar2009-08-27
| | | | | | | - No relocations yet, of course. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80235 91177308-0d34-0410-b5e6-96231b3b80d8

* Sketch TargetRegistry support for MCCodeEmitter abstract interface.Daniel Dunbar2009-08-27
| | | | | | | - Of course, nothing actually can provide this interface yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80188 91177308-0d34-0410-b5e6-96231b3b80d8
* Try to make MSVC just a little happier.Daniel Dunbar2009-08-27
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80187 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.Daniel Dunbar2009-08-26
| | | | | | | | | - I moved section creation back into AsmParser. I think policy decisions like this should be pushed higher, not lower, when possible (in addition the assembler has flags which change this behavior, for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80162 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Set .subsections_via_symbols flag properly.Daniel Dunbar2009-08-26
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80144 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Add support for relocations.Daniel Dunbar2009-08-26
| | | | | | | | | | - I haven't really tried to find the "right" way to store the fixups or apply them, yet. This works, but isn't particularly elegant or fast. - Still no evaluation support, so we don't actually ever not turn a fixup into a relocation entry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80089 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc/Mach-O: Add section padding where needed (to align the next section).Daniel Dunbar2009-08-26
| | | | | | | Also, simplify some of Mach-O writer code which can now use section addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80067 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert last patch. We need to put this into TargetLowering. There will be a lotBill Wendling2009-08-25
| | | | | | | of EH stuff going into there, so we can wait to add them all then. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80036 91177308-0d34-0410-b5e6-96231b3b80d8
* Comment formatting. Removing of unused #include and type forwarding.Bill Wendling2009-08-25
| | | | | | | OCD is fun! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80030 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a target asm info hook to specify that particular bits of data in the FDEBill Wendling2009-08-25
| | | | | | | | | | | should be forced to 32-bits (.long) even on 64-bit architectures. Darwin wants these bits to be 64-bits (.quad). However, other platforms may disagree. This is just the info right now and is part of a work-in-progress which needs this. We'll add the actual *use* of this soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80024 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Preliminary support for indirect symbols.Daniel Dunbar2009-08-24
| | | | | | | | | - The indirect table itself isn't being filled in yet. - This isn't factored properly and is rather FIXMEd, but at the moment I'm more focused on figuring out what it needs to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79910 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Support symbol attributes.Daniel Dunbar2009-08-24
| | | | | | | | - This is mostly complete, the main thing missing is .indirect_symbol support (which would be straight-forward, except that the way it is implemented in 'as' makes getting an exact .o match interesting). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79899 91177308-0d34-0410-b5e6-96231b3b80d8
