llvm dev - Feb 2009 - [LLVMdev] Debug Info Question

Hi,

 

I want to emit the debug information in assembly through assembler
directives. Also I don't want to emit debug information in sections
(like Dwarf). Instead the debug information will be interspersed with
the assembly. However in LLVM, debug info (e.g. stoppoint) is read and
made part of the DAG only when DwarfWriter is registered. 

 

How can I emit the debug information in assembly with out using
DwarfWriter?

 

Regards

Sachin

We are moving in the direction where DwafWriter won't be required  
while building DAG. The work is in progress to annotate machine  
instructions (DebugLoc etc..) with debugging information which can be  
directly interpreted by an asm printer. DwarfWriter will become dumb  
asm printer which will work directly based on incoming machine  
instruction stream.

Is there anything we can we help with?
