GettingDumps

ICC

To dump IR in ICC use the following command line:

icc <your src-file> -mP2OPT_il0_print=<num>

where num is a phase number.
Stderr is used as the output stream.

If num = -1 then the dump will be printed after each phase.
Phase numbering isn't successive, the numbers of phases seem to be chosen at random.

Numbers of the most useful phases:

• 6 - after building CFG
  
• 2510 - after some optimizations.
  
  

  GCC

  To dump IR in GCC use the following command line:
  

  gcc <your src-file> -df
  
  

  The output will be in src-file.cfg
