2010-03-19MCAssembler: Move ApplyFixup to the TargetAsmBackend, this is a target ↵Daniel Dunbar
specific not object writer specific task. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98947 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O: Lift the fixup evaluation and application up (to the same place), ↵Daniel Dunbar
and eliminate MCAsmFixup::FixedValue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98944 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O: Factor out ExecutePostLayoutBinding, to separate the post-layout ↵Daniel Dunbar
changes the object writer may need to make to the assembler from the actual .o writing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98943 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O: Lift relocation emission logic a bit higher to separate ↵Daniel Dunbar
evaluation / relocation handling from the actual .o writing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98942 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19fix an MCInstPrinter leak that jyasskin pointed out:Chris Lattner
createAsmStreamer now takes ownership of the instprinter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98939 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O: Add isScatteredFixupFullyResolved, which implements the correct ↵Daniel Dunbar
algorithm (used on x86_64) for determining whether an evaluated fixup is fully resolved (doesn't need relocation). - Test cases will follow, once we have x86_64 relocation support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98926 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O/x86_64: Add getAtom[ForAddress].Daniel Dunbar
- These find the defining symbol which identifies the containing atom for a symbol or address. They are currently very slow, but will be eliminated eventually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98925 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O: Factor out isScatteredFixupFullyResolvedSimple predicate, and fix ↵Daniel Dunbar
some corner cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98924 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19MC/Mach-O: Factor out isSymbolLinkerVisible method; "linker visible" is a ↵Daniel Dunbar
made up term to refer to non-temporary labels + temporary labels in sections-which-require symbols. For Darwin, it corresponds to symbols which effectively define an atom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98923 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-18MCValue: Change to holding MCSymbolRefExprs instead of MCSymbols, we will ↵Daniel Dunbar
need this for accessing to symbol modifiers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98791 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-18MC/Darwin: Add a new target hook for whether the target uses "reliable" ↵Daniel Dunbar
symbol differences, basically whether the assembler should attempt to understand atoms when using scattered symbols. Also, avoid some virtual call overhead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98789 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
2010-03-15MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.Daniel Dunbar
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue. - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98592 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15MC/Mach-O/x86_64: Temporary labels in cstring sections require symbols (and ↵Daniel Dunbar
external relocations, but we don't have x86_64 relocations yet). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98583 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98582 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
2010-03-14add a new CreateTempSymbol method, the use case forChris Lattner
CreateTempSymbol vs GetOrCreateTemporarySymbol are completely different. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98486 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-13MC/Mach-O: PCrel relocations weren't using the right base address, they areDaniel Dunbar
relative to the fragment address, not its offset. This was masked by the text section normally being at address 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98420 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13llvm-mc: Support -n, useful for comparing -integrated-as output since theDaniel Dunbar
compiler may not lead with the text section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98418 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-12MC/Mach-O: Implement initial support for relaxation.Daniel Dunbar
- The implementation is currently very brain dead and inefficient, but I have a clear plan on how to fix it. - The good news is, it works and correctly assembles 403.gcc (when built with Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g', the resulting binary is exactly equivalent to that when built with the system assembler. So it probably works! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98396 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-11MC/Mach-O: Start passing in the basic MCAsmLayout object.Daniel Dunbar

2010-03-11MC: Sketch initial MCAsmLayout class, which encapsulates the current layout ↵Daniel Dunbar
of an assembly file. The MCAsmLayout is also available for use by MCExpr::EvaluateAs{Absolute,Relocatable}, to allow target specific hooks and "absolutizing" of symbols. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98227 91177308-0d34-0410-b5e6-96231b3b80d8
