How to view variable content in IR?

[adriaanjacobs]

Hi!

Thanks for the useful utility, I've been using it for a while now.
Is it possible that I can't seem to be able to dump variable contents, though?

For unnamed variables, I get it. But even for named variables, GDB always responds with

No symbol "variable_name" in current context.

Any idea what's going wrong there?

Using the hello.ll example in test-files/ directory, if I use debugir ./hello.ll -instnamer to get hello.dbg.ll, and then run gdb as gdb --args lli -jit-kind=mcjit hello.dbg.ll, and set a breakpoint at hello.ll:16 and then run it, I can print %i in hello.ll as print i, and it just works.

Ah I see, using lli, thanks! Should have read the README better :)

Is there any reason why, under native debugging (without lli), this is not possible?

it should work theoretically, especially if line-by-line execution works (which you say it does, but i haven't tried). I don't know though. I'll try it sometime and check.
