From 4b2820534e3635a8ecd047f1e0139834e0a67d02 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 21 Jul 2010 15:39:23 +1000 Subject: r600g: add r600 compile mode to compiler. some of the ALU instructions are different on r6xx vs r7xx, separate the alu translation to separate files, and use family to pick which compile stage to use. --- src/gallium/drivers/r600/r600_compiler_r600.c | 65 +++++++++++++++++++++++++++ src/gallium/drivers/r600/r600_compiler_r700.c | 43 +++++++++++++----- src/gallium/drivers/r600/r600_shader.c | 6 ++- src/gallium/drivers/r600/r600_shader.h | 5 +++ 4 files changed, 106 insertions(+), 13 deletions(-) diff --git a/src/gallium/drivers/r600/r600_compiler_r600.c b/src/gallium/drivers/r600/r600_compiler_r600.c index f7234e7646..27ad8f1a18 100644 --- a/src/gallium/drivers/r600/r600_compiler_r600.c +++ b/src/gallium/drivers/r600/r600_compiler_r600.c @@ -905,3 +905,68 @@ struct r600_alu_instruction r600_alu_instruction[C_OPCODE_LAST] = { {C_OPCODE_ENTRY, INST_NOP}, {C_OPCODE_ARL, INST_NOP}, };
