Hello,
For the targets that support vectors, we can write the following code:
typedef short V4H __attribute__ ((vector_size (8)));
V4H tst(V4H a, V4H b){
return a + b;
}
Other operators such as -, *, |, &, ^ etc are also supported. However, vector
shift
is not supported by frontend, including both scalar and vector second operands.
V4H tst(V4H a, V4H b){
return a << 3;
}
V4H tst(V4H a, V4H b){
return a << b;
}
Currently, we have to use intrinsics to support such shift. Isn't syntax of
vector
shift intuitive enough to be supported natively? Someone may argue it breaks the
C language. But vector is a GCC extension anyway. Support for vector add/sub/etc
already break C syntax. Any thought? Sorry if this issue had been raised in
past.
