            Bug ID: 59522
           Summary: "cc1plus: error: unrecognized command line option
                    ‘-fmy-loop-block’ " is generated when g++ is run but
                    not with cc1plus
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: abhilash_bhandari at yahoo dot co.in

Hi All,

I want to add a new command line option '-fmy-loop-block'. I have followed the
gcc manual and added the option in common.opt . 

fmy-loop-block
Common Report Var(flag_my_loop_block) Optimization
Enable My Loop Blocking transformation

The option gets recognized by cc1plus but not by g++. 

Is there any other place where I need to register this option so that it works
with g++? Any help will be greatly appreciated.

Thanks and Regards,
Abhilash Bhandari

[Bug c++/59522] "cc1plus: error: unrecognized command line option ‘-fmy-loop-block’ " is generated when g++ is run but not with cc1plus

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The one thing is your new g++ is it executing your newly build cc1plus?  That
is the main reason why it would fail.  Try add -B . to the command line if you
are still in the build directory.

Even gcc-help might not be the correct place to ask this question.  gcc@ might
be better since this is a question about modifying gcc rather than using gcc.
