* CELL: two-sided stencil fixesRobert Ellison2008-11-1111-206/+115
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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

* | gallium: use PIPE_ARCH_SSE to protect use of SSE instrinsics onlyBrian2008-11-093-11/+35
| | | | | | | | | | | | 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.

* | CELL: fix several stencil problemsRobert Ellison2008-11-073-88/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This small set of changes repairs several different stenciling problems; now redbook/stencil also runs correctly (and maybe others - I haven't checked everything yet). - The number of instructions that had been allocated for fragment ops used to be 64 (in cell/common.h). With complicated stencil use, we managed to get up to 93, which caused a segfault before we noticed we'd overran our memory buffer. It's now been bumped to 128, which should be enough for even complicated stencil and fragment op usage. - The status of cell surfaces never changed beyond the initial PIPE_SURFACE_STATUS_UNDEFINED. When a user called glClear() to clear just the Z buffer (but not the stencil buffer), this caused the check_clear_depth_with_quad() function to return false (because the surface status was believed to be undefined), and so the device was instructed to clear the whole buffer (including the stencil buffer), instead of correctly using a quad to clear just the depth, leaving the stencil alone. This has been fixed similarly to the way the i915 driver handles the surface status: during cell_clear_surface(), the status is set to PIPE_SURFACE_STATUS_DEFINED. Then a partial buffer clear is handled with a quad, as expected. Note that we are *not* using PIPE_SURFACE_STATUS_CLEAR (also similar to the i915); technically, we should be setting the surface status to CLEAR on a clear, and to DEFINED when we actually draw something (say on cell_vbuf_draw()), but it's difficult to figure out exactly which surfaces are affected by a cell_vbuf_draw(), so for now we're doing the easy thing. - The fragment ops handling was very clever about only pulling out the parts of the Z/stencil buffer that it needed for calculations; but this failed when only part of the buffer was written, because the part that was never pulled out was inadvertently cleared. Now all the data from the combined Z/stencil buffer is pulled out, just so the proper values can be recombined later and written back to the buffer correctly. As a bonus, the fragment op code generation is simplified.
