2010-11-15Fix PR8565.Rafael Espindola
This moves most of the isUsed logic to the MCSymbol itself. With this we get a bit more relaxed about allowing definitions after uses: uses that don't evaluate their argument immediately (jmp foo) are accepted. ddunbar, this was the smallest compromise I could think of that lets us accept gcc (and clang!) assembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119144 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
2010-10-04Add hook in MCSection to decide when to use "optimized nops", for eachJan Wen Voung
section kind. Previously, optimized nops were only used for MachO. Also added tests for ELF and COFF. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115523 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30This is the last major patch to implement support for the .loc directiveKevin Enderby
and output the dwarf line number tables. This contains the code to emit and encode the dwarf line tables from the previously gathered information in the MCLineSection objects. This contains all the details to encode the line and address deltas into the dwarf line table. To do this an MCDwarfLineAddrFragment has been added. Also this moves the interface code out of Mach-O streamer into MCDwarf so it should be useable by other object file formats. There is now one call to be made from an MCObjectStreamer EmitInstruction() method: MCLineEntry::Make(this, getCurrentSection()); to create a line entry after each instruction is assembled. And one call call to be made from an MCObjectStreamer Finish() method: MCDwarfFileTable::Emit(this, DwarfLineSection); when getContext().hasDwarfFiles() is true and is passed a object file specific MCSection where to emit the dwarf file and the line tables. This appears to now be correct for 32-bit targets, at least x86. But the relocation entries for 64-bit Darwin needs some further work which is next up to work on. So for now the 64-bit Mach-O target does not output the dwarf file and line tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115157 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-29change the protocol TargetAsmPArser::MatchInstruction method to take anChris Lattner
MCStreamer to emit into instead of an MCInst to fill in. This allows the matcher extra flexibility and is more convenient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115014 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-24MC/AsmParser: Support .single and .double for embedding floating point literals.Daniel Dunbar
- I believe more modern 'gas' supports a more enhanced set of arithmetic on them, but for now the only thing we can do is emit them as data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114719 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-17MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing theDaniel Dunbar
expression to include the modifier. - Gross, but this a corner case we don't expect to see often in practice, but it is worth accepting. - Also improves diagnostics on invalid modifiers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114154 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-15Add a InitSections method to the streamer interface.Rafael Espindola
The ELF implementation now creates text, data and bss to match the gnu as behavior. The text streamer still has the old MachO specific behavior since the testsuite checks that it will error when a directive is given before a setting the current section for example. A nice benefit is that -n is not required anymore when producing ELF files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114027 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-11fix the asmparser so that the target is responsible for skipping toChris Lattner
the end of the line on a parser error, allowing skipping to happen for syntactic errors but not for semantic errors. Before we would miss emitting a diagnostic about the second line, because we skipped it due to the semantic error on the first line: foo %eax bar %al This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113688 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09llvm-mc: Don't crash when using -n and we see a directive before the initial ↵Daniel Dunbar
section. - This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113552 91177308-0d34-0410-b5e6-96231b3b80d8
