llvm dev - Jul 2009 - [LLVMdev] Pass Scheduling Information without using opt

Hello everybody,

is it somehow possible to get information about what passes were run in 
what order  or timing analysis of passes *without* using opt?
I am implementing a ModulePass that at some point creates a 
FunctionPassManager which runs several passes, but I cannot figure a way 
to output the same information as when running a command line tool as 
described in "Writing an LLVM Pass".

Regards,
Ralf

Hi Ralf,

I believe all you need to do is call llvm::llvm_shutdown().

Hey Daniel,

thanks for the response.

I am not sure that this is what I need. When and how should I call 
llvm_shutdown()?
After the FunctionPassManager is done, the calling ModulePass still 
performs quite a few actions on the transformed code and also calls the 
FunctionPassManager on different functions. However, I need to display 
statistics about the transformation of each function separately.
If I call llvm_shutdown() after the FunctionPassManager is finished, I 
do not get any output. Instead, the bitcode seems to get corrupted (at 
least the verifier reports a lot of "Intrinsic has wrong parameter 
attributes" warnings, the code still runs fine).

Cheers,
Ralf
