Hi, I am a compiler engineer base on GCC in China. Recently, I develop a new
pattern for vector widen multiply-accumulator(I call it widen fma) because the
ISA in my project has the instruction (vwmacc). I develop a lot of code
especiallly frontend (gimple&&generic) int GCC. This is useful for m

Hi All,
We are looking to implement saturation support in the compiler. The aim is to
recognize both Scalar and Vector variant of typical saturating expressions.
As an example:
1. Saturating addition:
char sat (char a, char b)
{
int tmp = a + b;
return tmp > 127 ? 127 : ((tmp
