2010-05-18Make EmitTBSSSymbol take a section argument so that we can find it later.Eric Christopher
Fix up callers and users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104057 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-17More data/parsing support for tls directives. Add a few more testcasesEric Christopher
and cleanup comments as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103985 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-17MC/Mach-O/x86: Optimal nop sequences should only be used for the .text ↵Daniel Dunbar
sections, not all sections in the text segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103981 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-17llvm-mc: Support reassignment of variables in one special case, when theDaniel Dunbar
variable has not yet been used in an expression. This allows us to support a few cases that show up in real code (mostly because gcc generates it for Objective-C on Darwin), without giving up a reasonable semantic model for assignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103950 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-17Assume that we'll handle mangling the symbols earlier and just put theEric Christopher
symbol to the file as we have it. Simplifies out tbss handling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103928 91177308-0d34-0410-b5e6-96231b3b80d8

Nothing uses this yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103757 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-13fix rdar://7965971 and a fixme: use ParseIdentifier inChris Lattner
ParseDirectiveDarwinZerofill instead of hard coding the check for identifier. This allows quoted symbol names to be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103682 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14implement mc asmparser support for '.', which gets theChris Lattner
current PC. rdar://7834775 We now produce an identical .o file compared to the cctools assembler for something like this: _f0: L0: jmp L1 .long . - L0 L1: jmp A .long . - L1 .zerofill __DATA,_bss,A,0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101227 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
2010-04-05Give AsmParser an option to control whether it finalizesChris Lattner
the stream.

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
2010-03-15MC: 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
2010-03-13llvm-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

2010-03-10eliminate MCContext::CreateSymbol and CreateTemporarySymbol.Chris Lattner
Add a new GetOrCreateTemporarySymbol method and a version that takes a twine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98118 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26pass in more section kinds, enough to get the .align 0x90Chris Lattner
stuff to emit optimal nops in the right places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97233 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25This is a patch to the assembler frontend to detect when aligning a textKevin Enderby
section with TextAlignFillValue and calls EmitCodeAlignment() instead of calling EmitValueToAlignment(). This allows x86 assembly code to be aligned with optimal nops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97158 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-24fix a parsing problem on instructions like:Chris Lattner
movw $8, (_cost_table_-L97$pb)+66(%eax) After the parens, we could still have a binop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94345 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22move some files out of the llvm-mc tool into the MCParser library soChris Lattner
other tools can link it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94131 91177308-0d34-0410-b5e6-96231b3b80d8
