modify gcc stack

modify gcc stack

[Lisa Alano]

Hi,

Can anybody give me a clue as to how to approach the problem of modifying
the stack layout for gcc? I am not a compiler expert, but am trying to
experiment with a new chip architecture that uses a special instruction
that adds an extra 4 bytes after a buffer declaration or after the return
address. (I guess it would be similar to adding a canary like propolice or
stackguard) Can anybody help or point me in the right direction?

Thanks.
