llvm dev - Jun 2011 - [LLVMdev] dump a module from inside GDB to a file

Ankit,
>From within GDB you can run the following command:
"call m->dump()"
This will print the module in the bitcode in a textual format.

Subject: [LLVMdev] dump a module from inside GDB to a file

Hi All,

I changed the CFG of a big function using a pass that runs on a function, I am
having trouble debugging it. Is there someway to dump a module to a file from
inside gdb? I have access to the Module pointer. Let me know if anything else is
needed.

Hi Nadev,


The module is really big and i would like the dump to happen in a file
instead of stdout. Is that possible?

Maybe you can tell gdb to direct stderr to a file, do the dump, then redirect
stderr to the usual place?

Ciao, Duncan.
