faea860c27 Attempt to match the SSE2 version of the hash. 
Not tested, don't currently have an ARM device.  May or may not have a
performance hit.

3977f5a8ec Add a non-SSE implementation of the QuickTexHash. 
This way we can use it as a stable value for texture replacements.

2b16b5b79b Use XXH64 on 64-bit systems. 
I'm not able to reproduce any real performance difference, but I know
there are some games which do more hashing and it may help there.

b800762ceb Add a NEON-optimized version of XXH32. 
This takes at least 40% less time to hash on NEON/ARM devices.

a26e6ce4b6 Minor improvements to QuickTexHashNEON(). 
Cuts a VFP switch, oops.

970dd4f2f8 Use vldmia not vld1 for QuickTexHashNEON(). 
It turns out this is ~20% slower usually, so aligned is not worth the
pipeline hit.

b44d10a91e Move texture unswizzling to decoder, use NEON. 2014-03-22 21:35:16 -07:00

2623f6bfe2 Disable the optimized hash on iOS, seems to crash. 
Except not for me, not sure why.

53800bd413 Disable the hand-coded NEON texture hash again. It's slow, for unknown reasons. 2013-11-11 14:39:29 +01:00

fa79d7f13c Handcode the non-NEON texcache hash as well on ARM. 
Well, it could be a better algorithm, but at least this uses LDMIA.

2dfa2379f4 Rewrite QuickTexHashNEON directly in asm. 
Seems like gcc couldn't optimize it to this.

64e977db08 Improve the non-NEON tex hash path on ARM. 
This generates better looking disassembly, though a small change.

4d47ccd5df Add a NEON version of the tex hash. 
Should be used only for NEON devices.  Currently only compiled on Android.
