Merge pull request #1812 from PatrickvL/trampoline_optimization 
Trampoline optimization

cb4d27728c This moves construction of lookup strings outside call-locations towards a central LookupTrampolines() function, reducing the overhead of calling a trampoline down to a minimum. 2019-12-31 12:04:06 +01:00

36569f0d2e This prevents "error X5765: Dest register for LRP cannot be the same as first or third source register" in WWE RAW2. 
A little background information :

When compiling pixel shaders, to facilitate later optimizations, FixOverusedRegisters() inserts MOV opcodes reading from constant, vertex color or texture registers, and writing to a free R register slot.

In this case, this transformed :

````
lrp r0, c0,r2,c1
````

into

````
mov r0, c0
lrp r0, r0,r2,c1
````

Not only introduces this a completely useless additional MOV (to R0, which is overwritten by the next LRP opcode), but it also results in LRP reading from R0, which is the same register it's writing to, which seems to be forbidden.

This fix prevents that from happening, by not-inserting a MOV when this situation would arise.

It's possible there exist more such scenario's, but let's tackle them when they are reported.

As for the other change in this commit : Instead of repeating a nearly identical while-loop three times, this loop is now wrapped in a for-loop, that handles all three versions (for PARAM_C, PARAM_V and PARAM_T type registers).

f97a642bc9 Fixed XDK Fog sample over-saturation by literally saturating all COLOR-semantic outputs (oD0, oD1, oB0 and oB1)!

d28b4836fd Halve the selection of input attrbibute or constant, using lerp. 
For this, made sure that the crossover value (as set in SetOverrideFlags) is either 0 or 1.

Also replaced the v0..v15 defines by actual variables. Instead, manually unrolled the initialization code via a concatenating define.
