Subject: [PATCH] Improve BlockPosition inlining
|
|
|
|
Normally the JVM can inline virtual getters by having two sets of code, one is the 'optimized' code and the other is the 'deoptimized' code.
|
|
If a single type is used 99% of the time, then its worth it to inline, and to revert to 'deoptimized' the 1% of the time we encounter other types.
|
|
But if two types are encountered commonly, then the JVM can't inline them both, and the call overhead remains.
|
|
|
|
This scenario also occurs with BlockPos and MutableBlockPos.
|
|
The variables in BlockPos are final, so MutableBlockPos can't modify them.
|
|
MutableBlockPos fixes this by adding custom mutable variables, and overriding the getters to access them.
|
|
|
|
This approach with utility methods that operate on MutableBlockPos and BlockPos.
|
|
Specific examples are BlockPosition.up(), and World.isValidLocation().
|
|
It makes these simple methods much slower than they need to be.
|
|
|
|
This should result in an across the board speedup in anything that accesses blocks or does logic with positions.
|
|
|
|
This is based upon conclusions drawn from inspecting the assenmbly generated bythe JIT compiler on my microbenchmarks.
|
|
They had 'callq' (invoke) instead of 'mov' (get from memory) instructions.
