Debug Info Question

Project Infrastructure LLVM Dev List Archives

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.

Is there anything we can we help with?
