Proposal for function vectorization and loop vectorization with function calls
...A new vector function generation pass is introduced to generate vector
variants of the original scalar function based on VectorABI (see [2, 3]).
For example, one vector variant is generated for "_ZGVbN4ul_" attribute
as follows (pseudo code):
define __stdcall <4 x f32> @_ZGVbN4ul_dowork(f32* %a, i32 %k) #0
{
#pragma clang loop vectorize(enable)
for (int %t = k; %t < %k + 4; %t++) {
%a[t] = sinf(%a[t]) + 9.8f;
}
vec_load xmm0, %a[k:VL]
return xmm0;
}
The body of the function is wrapped inside a loop having VL iterations,
which corresp...
