2006-11-16Initial implementation work for CAL, RET, and BRA instructions for fragmentBrian Paul
programs.
2006-10-29Change _mesa_init_instruction() to initialize an array of instructions.Brian Paul
2006-05-30Define new NEGATE_* tokens for setting the src register's NegateBase field.Brian Paul
Before, we were using GL_TRUE/GL_FALSE in a few places. Note: only the SWZ instruction can negate individual components.
2005-11-20Make Saturate a 2-bit field again, renamed to SaturateMode with threeBrian Paul
possible values: SATURATE_OFF, SATURATE_ZERO_ONE and SATURATE_PLUS_MINUS_ONE.
2005-11-19Saturate is a 1-bit boolean fieldBrian Paul

2005-11-08This patch adds the missing NV_vertex_program2 and NV_vertex_program3Ian Romanick
instructions to the various internal tables. It does not add support for them to the parser nor does it add support for them to the program interpreter. It also corrects some errors in the comments in program_instruction.h. This patch breaks the instruction union in t_vb_arbprogram.h. The opcode field in that union was only 6 bits. When there were only 59+3 instructions that worked fine. However, this patch increases the base instruction count to 69. This requires 7 bits. The problem is that increasing the opcode width to 7 bits increases the size of instruction::rsw to 33 bits. I've increased the size of the union to 64-bit, but this is just a temporary hack (and probably breaks the build on some systems).
2005-11-05consolidate vertex/fragment program printing into _mesa_print_program()Brian Paul
2005-11-05added _mesa_program_file_string()Brian Paul
2005-11-05added _mesa_num_inst_src_regs() and _mesa_opcode_string()Brian Paul
2005-11-05Unify vertex/fragment program instuctions.Brian Paul
Based on patch by Ian (#4967) but also unify instruction opcodes.
