If such a mechanism existed, asm programs would able to be structured to
honor their declaration as such; thereby enable implementations of set/longjump
to exclude them from being otherwise improperly save/restored, for example, etc.

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-06-19 22:57 -------
I don't understand what you want here, a preprocessed define when -ffixed-reg-* is supplied.  Well that 
is hard really and not very useful as usually asm is not preprocessed.

I am closing this as "will not fix".  You should make a policy for your projects to use a define with the 
additional of -ffixed-reg-*.
