Hi David,

Whose decision will this be? Is this going to be a community based decision
or will gcc decide to do this unlaterally with or without the community's
support?
What voice should the currently shipping distributions have in this?
I saw no discussion on gcc-bugs about this issue (and was not privy to your
and Geoff's previuous discussion with Andy about this issue).
That is why I responded to Andy in the first place.
What process, if any exists for this decision to be made?
I assume you wanted a community based decision since you asked Andy to cc
this to the linuxppc dev list.
Also, on a more technical note, how many <= 8 byte structures are there in
actual use anyway? I would guess that most uninos are less than or eqaul to
8 bytes and so returning unions would change. So according to the abi, would
we would passing a union in to a function via a pointer but returning one in
registers?
