subroutine kernel error
-----------
kernel void helper(float a, float b, out float c)
{
c=a+b;
}
kernel void sum(float a<>, float b<>, out float c<>
{
helper(a,b,c);
}
----------------------------
error msg : Not support kernel local\parameter data structure type:non-reduce output parameter must be stream type.
how to use sub-soutine?
<topic 2>
I tested sha1 function as subroutine.
when I compile IL to ISA, sha1 subroutine is compiled as inline function.
------------------------------------------
mov r301, r1011
mov r302, r1012
call 38 ; sha1 function
mov r1013, r303
mov r1014, r304
....
mov r301, r1011
mov r302, r1012
call 38 ; sha1 function
mov r1013, r303
mov r1014, r304..
....repeat
--------------------------------------------
inlined sha1 code asm (Not calling)
inlined sha1 code asm (Not calling)
--------------------------------------------
IL code use call sha1, but asm code is assembled as inline code.
but i think that large code is slower than short code.
i want that sha1 subroutine is not inline function.
Can i control? is there a option for compile?
or another trick?

There is no way to control this. In GPGPU programming, subroutines are allways inlined as hardware has limited stack or no stack.
