environment register / ABI

[Martin Uecker]

Hi all,

does anybody know if all architectures support passing
an environment pointer in their function call ABI? 

Are the some where this does not exist?

Is there are table somewhere which lists the
register (or stack slot) used for this for
all architectures?

Somehow I could not find this information easily.
One could assemble this going through all the
ports, but maybe it exists somewhere already.

Best
Martin
