Age	Commit message (Collapse)	Author
2007-10-03	fix f/u mix-up in micro_trunc()	Brian

2007-10-03	move TEX code into exec_tex()	Brian

2007-10-02	clean-ups	Brian

2007-10-02	Implement/use fragment kill results	Brian

2007-10-02	Implement TGSI_OPCODE_SNE with micro_ne()	Brian

2007-10-02	Separate TGSI_OPCODE_KIL and TGSI_OPCODE_KILP (predicated).	Brian
	These correspond to the NV and ARB-style fragment program KIL instructions. The former is really supposed to examine the NV condition codes but Mesa's GLSL compiler always emits unconditional KIL instructions.
2007-10-02	Push mask stacks upon CAL, pop upon RET.	Brian
	Still need to handle conditional RET statements...
2007-10-02	added license and interpreter comments	Brian

2007-10-02	Implement CONT statement.	Brian

2007-10-02	added micro_trunc(), re-order some code	Brian

2007-10-02	Minor optimization: no-op CAL when ExecMask==0x0.	Brian

2007-10-02	Added TGSI_FILE_OUTPUT case in fetch_src_file_channel().	Brian
	GLSL output variables (such as vertex varyings) can be read (they're not write-only).
2007-10-02	Implement CAL/RET and a call stack for subroutines.	Brian
	The glsl/brick.c shader demo runs now.
2007-10-02	Added TGSI_OPCODE_END	Brian
	Halt program execution when we get to END instruction. The GLSL compiler puts subroutines after the end instruction so we have to stop before then.
2007-10-02	Fold expand_program() into tgsi_exec_prepare()	Brian

2007-10-02	no more need for tgsi_exec_machine_run2(), remove dead code	Brian

2007-10-02	Move tgsi machine state init/allocations so they're done less frequently.	Brian
	This, plus expanding all instructions ahead of time, seems to have improved the performance of program execution by 8x or so.
2007-10-02	checkpoint: unpack all instructions before interpretation. Actual looping ↵	Brian
	works.
2007-09-29	Initial conditional execution support for loops and BRK instruction.	Brian
	Also, instead of passing cond mask to each micro op, just apply it in the store_dest() function.
2007-09-28	Initial implementation of IF/ELSE/ENDIF using conditional masking.	Brian
	mach->CondMask controls writing to each of the 4 components in a quad. mach->CondMaskStack handles nested conditionals. Only a few of the micro ops (add/sub/mul/store) have been updated to obey CondMask at this time.
2007-09-18	Fix some issues with perspective-corrected interpolation.	Brian
	In mesa_to_tgsi.c, use TGSI_INTERPOLATE_PERSPECTIVE by default (to match post-transform vertex info convention). More to be done there... In sp_quad_fs.c, interpolate W in addition to Z. This fixes the divide by zero happening in perspective_interpolation() tgsi_exec.c As it was, we were only getting perspective correction of texture coords used by the TGSI_TEX instruction since it does a homogeneous divide. Other coords/varyings were incorrect.
2007-08-24	Hook-up SSE2 to VS.	michal

2007-08-24	Rename tgsi "core" directory	Keith Whitwell
