2008-11-11CELL: two-sided stencil fixesRobert Ellison
With these changes, the tests/stencil_twoside test now works. - Eliminate blending from the stencil_twoside test, as it produces an unneeded dependency on having blending working - The spe_splat() function will now work if the register being splatted and the destination register are the same - Separate fragment code generated for front-facing and back-facing fragments. Often these are the same; if two-sided stenciling is on, they can be different. This is easier and faster than generating code that does both tests and merges the results. - Fixed a cut/paste bug where if the back Z-pass stencil operation were different from all the other operations, the back Z-fail results were incorrect.

2008-11-09util: Fix util_fast_pow/exp2/log2.Brian
- Use a lookup table for log2. - Compute (float) (1 << ipart) by tweaking with the exponent directly to avoid integer overflow and float conversion. - Also table negative exponents to avoid float division and branching. - Implement util_fast_exp as function of util_fast_exp2. -------- Cherry-picked from gallium-0.2: 8415d06d90a197e16554dab98d160334fd9f9f93 This fixes some pow() glitches seen in fslight.c, spectex.c, etc. Conflicts: src/gallium/auxiliary/util/u_math.h
2008-11-09gallium: _debug_vprintf() should be silent if DEBUG is not definedBrian
2008-11-09gallium: use PIPE_ARCH_SSE to protect use of SSE instrinsics onlyBrian
This allows us to use SSE codegen with debug builds again. When PIPE_ARCH_SSE is set (w/ gcc -msse -msse2) we will also use the gcc SSE intrinsic functions.

2008-11-05gallium: check execution mask in indirect register loadsBrian
Zero-out the index for disabled execution channels to avoid using potential garbage values (thus avoiding bad array indexing).

Fixes progs/vp/arl.txt test.

2008-11-05gallium: call tgsi_set_exec_mask() and use exec mask in SSE ARL codeBrian Paul
This prevents vertex shaders from referencing invalid memory locations when the shader is operating on less than four vertices or fragments.

2008-10-29gallium: fix alignment parameter passed to u_mmAllocMem()Brian Paul
Was 32, now 5. The param is expressed as a power of two exponent. The net effect is that the alignment was a no-op on X86 but on PPC we always got the same memory address everytime rtasm_exec_malloc() was called.
