[LLVMdev] understanding the opt tool

[Duncan Sands]

Hi Kalyan,

> opt -strip-dead-prototypes -f <filename.bc> filename2.bc

you have to specify the list of passes to run.  -strip-dead-prototypes
only removes unused declarations.  If there are none, it will do nothing.
Try:
   opt -std-compile-opts -f <filename.bc> filename2.bc

Ciao,

Duncan.
