llvm dev - Nov 2008 - [LLVMdev] getModuleIdentifier() returns <stdin>

Hi all,

I'm writing my own pass and use "opt" to launch it. In my pass,
I'd like to
see the name of the module I'm working on, so I use getModuleIdentifier(),
trying to get the name such as "test.bc." But the result is always
<stdin>.

Could anyone please help me on this?

Thank you very much.

Jack

Is opt reading the input bitcode from standard input (as opposed to 
being given a filename)?  If so, that is probably why the module is 
named stdin.

Hi John,

I run my pass this way:

opt -mypass <input.bc >output.bc

So I think "input.bc" is what I should expect, right?

Thanks,
Jack
