Hello I was trying out the Vector API and was surprised by the amount of boolean[] allocations the code made. The code is here [1].
With JDK 23 on an AMD Ryzen 7 PRO 5750GE (preferred size 256 bit) allocations were: - about 1 million ByteVector.ByteMasks with a shallow size of 18 MB - about 2 million boolean[] with a shallow size of 100 MB, suggesting for every ByteMask two boolean[] are allocated - 125k ByteVector with a shallow size of 2 MB I wanted to ask whether in the past any considerations where given to replace the boolean[] with bitmasks, for example an int or long. Certain mask operations could then become simple integer operations, for example #eq(), #not(), #anyTrue(), #allTrue(), #toLong(), #and(), #or(), #xor() and so forth. I have no idea about the impact this would have on the rest of the system like the compiler and native code.
