8291118: [vectorapi] Optimize the implementation of lanewise FIRST_NONZERO

11

Vector API binary op "`FIRST_NONZERO`" represents the vector operation of "`a != 0 ? a : b`", which can be implemented with existing APIs like "`compare + blend`". The current...

8291600: [vectorapi] vector cast op check is not always needed for vector mask cast

7

Recently we found the performance of "`FIRST_NONZERO`" for double type is largely worse than the other types on x86 when `UseAVX=2`. The main reason is the "`VectorCastL2X`" op is not...

8293409: [vectorapi] Intrinsify VectorSupport.indexVector

8

"`VectorSupport.indexVector()`" is used to compute a vector that contains the index values based on a given vector and a scale value (`i.e. index = vec + iota * scale`). This...
