Подскажите на каких компилерах -g опускает оптимизацию до нуля?

Description 
This option tells the compiler to generate symbolic debugging information in the  object file for use by debuggers.  
The compiler does not support the  generation of debugging information in  assemblable files. If you specify this opt
ion, the resulting obj ect file will contain  debugging information, but the  assemblable file will not.

This option turns off O2 and makes O0 (Linux and Mac OS X)
or Od (Windows) the default

unless O2 (or another O option) is explicitly specified in the same command line. 

$ gcc -Q --help=optimizers > gcc
$ gcc -Q -g --help=optimizers > gcc-g
$ gcc -Q -O2 --help=optimizers > gcc-O2
$ gcc -Q -O2 -g --help=optimizers > gcc-O2-g
