fe6d2d4017 Avoid unaligned accesses when hashing vertex data on ARM. Fixes #9114, may help #9128 and #9129. 2016-12-01 15:56:05 +01:00

8c3552de74 cmake: Detect features at compile time 
Instead of relying on manually passed down flags from CMake,
we now have ppsspp_config.h file to create the platform defines for us.
This improves support for multiplatform builds (such as iOS).

9224eb375f Correct bezier handling for 0 division. 
This should still be drawn and treated as 1.

b1f0d4869c Advance pointers after drawing splines. 
Tests show this is just like beziers.

868bbb8ebe Advance vertex/index pointers on bezier submit. 
Just like other primitives.

808c807448 Allow tessellation with less than a 4 factor. 
Per tests on real hardware, this is allowed.  It works fine without the
clamping and matches the result on hardware.

277b76e2ae Treat GE_PATCHPRIM_UNKNOWN as points. 
Confirmed by tests on hardware - although it's doubtful any games use
this type.

1e0051a792 Add support for 32-bit indices. 
Not clear how often these are used by games.  Let's find out.

c0660c5ee7 Simplify some repeated code patterns a bit. 
Doesn't save many lines of actual code, though...

555c76d439 Use bernstein for texcoord interpolation too. 
This also closely matches hardware.

2bafba3909 Interpolate bezier patch colors using bernstein. 
This closely matches hardware (some color values seem to be off by one.)

See #7525.

7bfe100b0f Fix some unused variable warnings. 
The CheckAlpha one looks like it will matter.

033798c796 Expand spline data into a separate buffer. Prevent overflowing it by reducing the size of spline draws if necessary (but shouldn't really happen).
