* Fix PR8565.Rafael Espindola2010-11-151-6/+25
| | | | | | | | | | | 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. llvm-svn: 119144

* Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel!Kevin Enderby2010-10-041-1/+1
| | | | | | | | | | | | | | | | 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. llvm-svn: 115551
* Add hook in MCSection to decide when to use "optimized nops", for eachJan Wen Voung2010-10-041-6/+1
| | | | | | | section kind. Previously, optimized nops were only used for MachO. Also added tests for ELF and COFF. llvm-svn: 115523
* This is the last major patch to implement support for the .loc directiveKevin Enderby2010-09-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 115157
