gcc caller save register

[Johnny]

Hi,
On StrongArm architecture, some registers are caller save and some
are callee save. I want to make all my functions have the same register
values upon entry and exit. Is there a gcc flag to reserve and restore
all registers in a function (except the return value register)?

Thanks,
Aung

Off topic here.
I'd suggest giving the question a try in gnu.gcc.help.
