...the target is using .loc/.file, the assembler will be emitting the // .debug_line table automatically. if (MAI->hasDotLocAndDotFile()) return; Previously .loc directives are printed by selecting ISD::DEBUG_LOC nodes to pseudo instructions which print as the directive. For example: def DWARF_LOC : Pseudo<(outs), (ins i32imm:$line, i32imm:$col, i32imm:$file), ".loc $file, $line, $col", [(dwarf_loc (i32 imm:$line), (i32 imm:$col), (i32 imm:$file))]>; ISD::DEBUG_LOC nodes are produced when debug stoppoints are expanded. However debug stoppoints are no...

It seems to me that emitting DWARF line number information using .loc directives is currently broken. CellSPU is currently the only in tree target that sets HasDotLocAndDotFile in its MCAsmInfo and I can't get it to produce any line number information. Is this a known issue? I understand that there are lots of changes going on in this area. Any idea what it would take to fix? -- Richard

OK, here's a new patch that adds the infrastructure and the implementation for X86, ARM and PPC of GetInstSize and GetFunctionSize. Both functions are virtual functions defined in TargetInstrInfo.h. For X86, I moved some commodity functions from X86CodeEmitter to X86InstrInfo. What do you think? Nicolas Evan Cheng wrote: > > I think both of these belong to TargetInstrInfo. And
