Default compiler flags in specs file

Default compiler flags in specs file

[Asfand Yar Qazi]

Hi,

Does anybody know if its possible to change the default compiler flags 
gcc sends to the cc1 and cc1plus commands in the specs file?  Or are 
they hardcoded into the gcc frontend?

I'm talking about flags like -mtune, etc. which seem to appear when 
gcc is called as 'gcc -v'.

Thanks,
	Asfand Yar

You can change them there --- although as it makes your makefiles have
different effects on your system than on others', you might not like to
do that.

You'd better add them in a new specs line called from *cpp:, *cc1:, and
*cc1plus:, since it should be defined before the *cpp_cpu line is
reached.

Myself, I'd prefer to use a site-config file and/or a makefile fragment.
