Thanks for the info Dave. I downloaded the tar ball but facing issues
while building it:
prompt:>~/shared_scripts/bin/gcc-py-plugin/gcc-python-plugin-6f960cf 1020> make
python generate-config-h.py -o autogenerated-config.h --gcc=gcc
Traceback (most recent call last):
File "generate-config-h.py", line 21, in <module>
from configbuilder import ConfigBuilder

from subprocess import Popen, PIPE, check_output
ImportError: cannot import name check_output
make: *** [autogenerated-config.h] Error 1
hyper66:~/shared_scripts/bin/gcc-py-plugin/gcc-python-plugin-6f960cf 1021>
I am not that familiar with Python - can you please help me out?
Also please let me know some references on how to write a new PASS
within GCC codebase?
Regards,
Prakash
