From a77e813de32643ae2dfffd7ad12abed596172cab Mon Sep 17 00:00:00 2001 From: Henri Verbeet Date: Mon, 7 Feb 2011 15:22:07 +0100 Subject: r600g: Split r600_bc_alu_src. The r600_bc_alu_src structure is used in two different ways, as a vector and for the individual channels of that same vector. This is somewhat fragile, and probably confusing. --- src/gallium/drivers/r600/r600_shader.c | 295 ++++++++++++++++----------------- 1 file changed, 143 insertions(+), 152 deletions(-) (limited to 'src/gallium/drivers/r600/r600_shader.c') diff --git a/src/gallium/drivers/r600/r600_shader.c b/src/gallium/drivers/r600/r600_shader.c index 2194c17961..abb9ee0e8c 100644 --- a/src/gallium/drivers/r600/r600_shader.c +++ b/src/gallium/drivers/r600/r600_shader.c @@ -280,6 +280,15 @@ void r600_pipe_shader_destroy(struct pipe_context *ctx, struct r600_pipe_shader */ struct r600_shader_tgsi_instruction;
