[Bug c++/35889] New: spu_check_builtin_parm function fails on templates.

[rbertran at ac dot upc dot edu]

Hello,

I'm using gcc4.3.0 for compiling cell binaries on a x86 platform.
I've some benchmarks that use c++ templates like:

template < typename T> inline
T rot_veci( T v, int n )
{
return (T) si_rotqbyi( (vector signed char)v, n );
}

When compiling, I get the following error:

error: si_rotqbyi expects an integer literal in the range [-64, 127].

So, I suppose that gcc is not able to know the value of the 'n' parameter.
Then, the builtins intrinsics checks for the literal range and raise the
error.

I've been googling and I found references [1][2] about this problem (or
similar problem). I guess that the problem comes from the
spu_check_builtin_parm function in gcc/config/spu/spu.c . I have reported
the problem to IBM cell forums, too.

Thanks in advance,
Salut!
