[LLVMdev] using large structures in registers/returns
...ormation about using structures directly as
parameters, returns, and in registers. Is this fully supported on all
platforms? Does it always convert to creating a hidden parameter when
too large?
For example (assume very.large is too big to fit in the target machine
registers):
define %very.large @get_struct() {
%m1 = insertvalue %very.large undef, i32 10, 0
...
%m10 = insertvalue %very.large %m9, i32 25, 9
ret %very.large %m10
}
define void @use_struct( %very.large %m ) { ... }
define i32 @main() {
%m = call %very.large @get_struct()
call void @use_struct( %very.large %m )
}
Will this work on...
