is there any reason why

asm volatile ("movl $32,%%ebp"
		::: "%ebp" );

is completely ignored by gcc? by that i mean that i've told it ebp has been
clobbered and on the next line it generates in the .S file it promptly tries
to load something using ebp and hence crashes miserably :)
i thought the whole idea of having a clobber list was so that it knew not
to use that value and to reload it, or push/pull it whatever.

also, when using floating point and a few registers on the stack i get
'more than 10 operands in asm' errors. any particular reason why? and how
should i avoid this? i'm using "m" when i pass the values i want, and trying
to pass too many gives this error. is there a way to reference the stack
directly? ie st(0) st(1) st(n) and would that solve the problem maybe?

regards,
nik
