Subject: [PATCH] Make sure inlined getChunkAt has inlined logic for loaded
|
|
chunks
|
|
|
|
Tux did some profiling some time ago and showed that the
|
|
previous getChunkAt method which had inlined logic for loaded
|
|
chunks did get inlined, but the standard CPS.getChunkAt
|
|
method was not inlined.
|
|
|
|
Paper recently reverted this optimisation, so it's been reintroduced
|
|
here.
