| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* add a new EmitInlineAsm function to asmprinter to handle inline asm.Chris Lattner2010-04-031-0/+9
| | | | | | | If we have an MCAsmStreamer, we continue to emit asm textually, otherwise we (currently) emit an error to errs and ignore it. llvm-svn: 100289
* add a EmitSymbolValue convenience method to MCStreamer.Chris Lattner2010-03-091-0/+5

* Make AsmStreamer maintain a notion of the current section, pushing it up ↵Chris Lattner2009-08-181-1/+1
| | | | | | | | | | | | from the MCAsmStreamer. Based on this, eliminate the current section from AsmPrinter. While I'm at it, clean up the last of the horrible "switch to null section" stuff and add an assert. This change is in preparation for completely eliminating asmprinter::switchtosection. llvm-svn: 79324
