Structure members in asm using one register only

[Maurizio Monge]

Hi, i am trying to make gcc access the members of a class
using only one register (for the class address).
If i do:
[member1] "m" (this->member1),
[member2] "m" (this->member2),
etc.
gcc will put the address of this->member1 in one register,
address of this->member2 in another one, etc...

i know that i can do
[thiz]  "r" (this)
and access the members as xyz([this]) with the right xyz,
but is there a more intelligent way than looking for all the structure
offsets and putting them directly in the as code?

Thanks
