If you're only building chrome, not the unit_tests target, you can
instead define gcc_version to 44.  This is picked up in v8.gyp to
enable the appropriate flags, but leaves strict aliasing on for the
rest of chrome.

 {
   'variables': {
 'gcc_version': 44,
   }
 }

I figure this is a better option as regressions will be caught as they
are introduced.

Hi all,

2009/11/2 Hironori Bono (坊野 博典) hb...@chromium.org


 1. Creating a file ~/.gyp/inclulde.gypi'.
 2. Adding a following lines to the file.

  {
'variables': {
  'no_strict_aliasing': 1
}
  }


IIRC specifying 'gcc_version': '44' does the same thing as above. This might
be better than specifying 'no_strict_aliasing' directly.

3. Run gclient runhooks --force to re-build scons or make files.
 4. Run hammer or make to re-build Chromium.


Thanks,
Yuta

Ah, you bet me to it.  You're right; gcc_version is used to only
enable -fno-strict-aliasing when building v8.
