[llvm-dev] Help adding entries to .symtab

[Robinson, Paul via llvm-dev]

The .symtab has symbols; you could define a label for the instruction, and store something in the symbol table entry for the label.  This kind of thing would be done in the MC layer.
This would be one way to provide annotations that aren't needed for execution.  If you need to change the instruction itself, for example to have the instruction refer to memory somewhere, then you need to modify the instruction itself.

Subject: [llvm-dev] Help adding entries to .symtab

Hi everyone,

I am fairly new to LLVM, I'm working on a new backend.
I am trying to add information to a specific instruction using the .symtab in the ELF format.
I've been searching through the LLVM source code trying to find a way to do such a thing.
Can anyone help me with some directions or point me to some documents in the matter.

Thanks, Liad.
