Hi all,
First, I am only looking at Linux. I don't have an Armv8 Mac so I can't check that.
The code is built, by default, for both Arm32 and Arm64.
The flag enable-fast-bitblt is set default to yes but can be turned off.
This flag only affects Arm32 and Arm64 builds and is ignored on other builds.
On Arm32 it works fully. On Arm64 there seems only to be a bug in fastPathBottomToTop.
This code is not built on x86-64 or other systems. Maybe it could be built, maybe not.
cheers
