Re: [Pocl-devel] async_work_group_copy

[Pekka J. <pek...@tu...>]

Erik,

The function protototype for the async copy includes a "gentype"
in a position not supported by the current "generator macros" of
yours.

event_t async_work_group_copy (
     __local gentype *dst,
     const __global gentype *src,
     size_t num_gentypes,
     event_t event);

What do you think is best way to generate the declarations and
definitions for such functions?

Something like:

#define __FUNC_PROTO(gentype)  \
         __attribute__ ((overloadable))  \
	event_t async_work_group_copy ( \
	    __local gentype *dst, \
	    const __global gentype *src, \
	    size_t num_gentypes, \
	    event_t event) \

#include "gentype_func_decl.inc"

Then that .inc would have the macro instantiated
with all the different value types for gentype. E.g.:

__FUNC_PROTO(float);
__FUNC_PROTO(float2);
__FUNC_PROTO(float4);
...

Similarly for the definitions. Here I think we
can assume both of the gentypes in the function
are always the same so we do not have to generate
all combinations.

What do you think?
