| | | | | | | | | | | and output the dwarf line number tables. This takes the current loc info after an instruction is assembled and saves the needed info into an object that has vector and for each section. These objects will be used for the final patch to build and emit the encoded dwarf line number tables. Again for now this is only in the Mach-O streamer but at some point will move to a more generic place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112668 91177308-0d34-0410-b5e6-96231b3b80d8

* MC/Mach-O: Reverse order of SymbolData scanning when emitting instructions.Daniel Dunbar2010-05-171-1/+1
| | | | | | | - This fixes a string table mismatch with 'as' when two new symbols are defined in a single instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103979 91177308-0d34-0410-b5e6-96231b3b80d8
* MC/Mach-O: Fix some differences in symbol flag handling.Daniel Dunbar2010-05-171-2/+15
| | | | | | | | | | | | | - Don't clear weak reference flag, 'as' was only "trying" to do this, it wasn't actually succeeding. - Clear the "lazy bound" bit when we mark something external. This corresponds roughly to the lazy clearing of the bit that 'as' implements in symbol_table_lookup. - The exact meaning of these flags appears pretty loose, since 'as' isn't very consistent. For now we just try to match 'as', we will clean this up one day hopefully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103964 91177308-0d34-0410-b5e6-96231b3b80d8

Once the compiler change is made and everything looks good the next patch with the table of optimal X86 nops will be added to WriteNopData() changing the output.
