Re-enable HAVE_NEON_INTRINSICS

[1bsyl]

It seems to me ARM_NEON is working and could be re-activated: https://github.com/libsdl-org/SDL_ttf/blob/main/SDL_ttf.c#L122

Does it build / work on windows versions too?

[1bsyl]

I haven't re-tried that, I think it did (window for window arm platform). never try compiling on windows for android. I probably can double-check (later..)

What testing have you done to verify it?

[1bsyl]

I haven't done more testing recently. (I'll try the window compilation more later). I don't know why this is back-out. I've using these neon intrinsic routines for years now on android without special crash about it

[1bsyl]

I have some trouble to try the ARM compilation of SDL_ttf on window. I have no device, my Visual Studio is old (2017) and not configured for ARM. Would be nice if someone with a setup ready could try it.

Is this planned for 2.20 ?

Is this planned for 2.20 ?

No, nobody has a setup to test it, so it'll have to go in post-release.
