2009-05-21cell: unroll inner loop of spu_render.c:cmd_render()Jonathan Adamczewski
It was taking approximately 50 cycles to extract the vertex indices, calculate the vertex_header pointers and call tri_draw() for each three vertices - . Unrolled, it takes less than 100 cycles to extract, unpack, calculate pointers and call tri_draw() eight times. It does have a nasty jump-tabled switch. I'm sure that there's a better way... Code size of spu_render.o gets larger due to the extra constants and work in the inner loop, there are extra stack saves and loads because there are more registers in use, and an assert. spu_tri.o gets a little smaller.

2008-10-03CELL: changes to generate SPU code for stencilingRobert Ellison
This set of code changes are for stencil code generation support. Both one-sided and two-sided stenciling are supported. In addition to the raw code generation changes, these changes had to be made elsewhere in the system: - Added new "register set" feature to the SPE assembly generation. A "register set" is a way to allocate multiple registers and free them all at the same time, delegating register allocation management to the spe_function unit. It's quite useful in complex register allocation schemes (like stenciling). - Added and improved SPE macro calculations. These are operations between registers and unsigned integer immediates. In many cases, the calculation can be performed with a single instruction; the macros will generate the single instruction if possible, or generate a register load and register-to-register operation if not. These macro functions are: spe_load_uint() (which has new ways to load a value in a single instruction), spe_and_uint(), spe_xor_uint(), spe_compare_equal_uint(), and spe_compare_greater_uint(). - Added facing to fragment generation. While rendering, the rasterizer needs to be able to determine front- and back-facing fragments, in order to correctly apply two-sided stencil. That requires these changes: - Added front_winding field to the cell_command_render block, so that the state tracker could communicate to the rasterizer what it considered to be the front-facing direction. - Added fragment facing as an input to the fragment function. - Calculated facing is passed during emit_quad().
