2011-07-20Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng
There is still a bit more refactoring left to do in Targets. But we are now very close to fixing all the layering issues in MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135611 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-20Add MCObjectFileInfo and sink the MCSections initialization code fromEvan Cheng
TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's *almost* gone! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135569 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo downEvan Cheng
to MCRegisterInfo. Also initialize the mapping at construction time. This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step towards fixing the layering violation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135424 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-18Make the StringMaps attached to MCContext use the MCContext's allocator; Eli Friedman
reduces the number of calls to malloc(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129687 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-09Initial support for the cfi directives. This is just enough to getRafael Espindola
f: .cfi_startproc nop .cfi_endproc assembled (on ELF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121434 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-01Rename temporary symbols if they conflict with artificial symbols createdRafael Espindola
by the assembler. This was blocking parsing any large .s produced by clang for example. Fixes PR8596. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120603 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Add .loc methods to the streamer.Rafael Espindola
Next: Add support for the !HasDotLocAndDotFile case to the MCAsmStreamer and then switch codegen to use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119384 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-13Parse and remember discriminators in .loc line. I try to output them withRafael Espindola
another patch. This lets us parse a bit more of the gcc 4.5 output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118975 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118699 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Fixed version of 118639 with an extra assert to catch similar problemsRafael Espindola
earlier. Implicit bool -> int conversions are evil! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118651 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-04Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel!Kevin Enderby
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better named. Since it is just a predicate and isn't actually changing any state. 2) Added a missing return in the comments for setCurrentDwarfLoc() in include/llvm/MC/MCContext.h for fix formatting. 3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change state. 4) Simplified the last test in isValidDwarfFileNumber() to just a one line boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115551 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Move logic of determining ELF entsize from the .s printer to initializationJan Wen Voung
time. That way, the EntrySize field is initialized for other code paths, namely, the .ll -> .o code path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115141 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-31This is the second of three patches to implement support for the .loc directiveKevin Enderby
and output the dwarf line number tables. This takes the current loc info after an instruction is assembled and saves the needed info into an object that has vector and for each section. These objects will be used for the final patch to build and emit the encoded dwarf line number tables. Again for now this is only in the Mach-O streamer but at some point will move to a more generic place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112668 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24First bit of support for the dwarf .loc directive. This patch updates theKevin Enderby
needed parsing for the .loc directive and saves the current info from that into the context. The next patch will take the current loc info after an instruction is assembled and save that info into a vector for each section for use to build the line number tables. The patch after that will encode the info from those vectors into the output file as the dwarf line tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111956 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-09Next bit of support for the dwarf .file directive. This patch takes theKevin Enderby
previously collected info from the .file directives and outputs the encoded bytes for it. For now this is only in the Mach-O streamer but at some point will move to a more generic place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110617 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-28Added first bit of support for the dwarf .file directive. This patch collectsKevin Enderby
the info from the .file directive and makes file and directory tables that will eventually be put out as part of the dwarf info in the output file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109651 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-08move macho section uniquing from MCParser and TLOF to MCContext whereChris Lattner
the compiler and asmparser now unique to the same sections. This fixes rdar://7835021. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100807 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Rip out the 'is temporary' nonsense from the MCContext interface toChris Lattner
create symbols. It is extremely error prone and a source of a lot of the remaining integrated assembler bugs on x86-64. This fixes rdar://7807601. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99902 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-17fix GetOrCreateTemporarySymbol to require a name, clientsChris Lattner
should use CreateTempSymbol() if they don't care about the name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98712 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15fix a memory leak yjasskin pointed out: MCSymbol is bump pointerChris Lattner
allocated and thus not freed. This is cool except that it contains and std::string so the string data didn't get freed. In any case there is no reason to redundantly store the string data in the MCSymbol anyway, just make the MCSymbol ref the string data in the MCContext StringMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98536 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.Daniel Dunbar
- 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
