From 279492386ffe741c2f5b91919b37068562b6a282 Mon Sep 17 00:00:00 2001 From: Michal Krol Date: Thu, 16 Sep 2010 16:51:03 +0000 Subject: [PATCH] svga: Integer constant register file has a separate namespace. Count int and float constants independently. Since there are only few i# constants available and hundreds of c# constants, it would be too easy to end up with an i# declaration out of its range. --- src/gallium/drivers/svga/svga_tgsi.c | 2 +- src/gallium/drivers/svga/svga_tgsi_emit.h | 3 ++- src/gallium/drivers/svga/svga_tgsi_insn.c | 12 ++++++------ 3 files changed, 9 insertions(+), 8 deletions(-) diff --git a/src/gallium/drivers/svga/svga_tgsi.c b/src/gallium/drivers/svga/svga_tgsi.c index 0cd620189b7..781fe6334a5 100644 --- a/src/gallium/drivers/svga/svga_tgsi.c +++ b/src/gallium/drivers/svga/svga_tgsi.c @@ -203,7 +203,7 @@ svga_tgsi_translate( const struct svga_shader *shader, emit.imm_start += key.vkey.num_zero_stride_vertex_elements; } - emit.nr_hw_const = (emit.imm_start + emit.info.file_max[TGSI_FILE_IMMEDIATE] + 1); + emit.nr_hw_float_const = (emit.imm_start + emit.info.file_max[TGSI_FILE_IMMEDIATE] + 1); emit.nr_hw_temp = emit.info.file_max[TGSI_FILE_TEMPORARY] + 1; emit.in_main_func = TRUE; diff --git a/src/gallium/drivers/svga/svga_tgsi_emit.h b/src/gallium/drivers/svga/svga_tgsi_emit.h index b4e90a957d0..63ef7f867a6 100644 --- a/src/gallium/drivers/svga/svga_tgsi_emit.h +++ b/src/gallium/drivers/svga/svga_tgsi_emit.h @@ -62,7 +62,8 @@ struct svga_shader_emitter int imm_start; - int nr_hw_const; + int nr_hw_float_const; + int nr_hw_int_const; int nr_hw_temp; int insn_offset; diff --git a/src/gallium/drivers/svga/svga_tgsi_insn.c b/src/gallium/drivers/svga/svga_tgsi_insn.c index ad7d27acbb0..f2591c5721a 100644 --- a/src/gallium/drivers/svga/svga_tgsi_insn.c +++ b/src/gallium/drivers/svga/svga_tgsi_insn.c @@ -553,7 +553,7 @@ static boolean emit_def_const( struct svga_shader_emitter *emit, static INLINE boolean create_zero_immediate( struct svga_shader_emitter *emit ) { - unsigned idx = emit->nr_hw_const++; + unsigned idx = emit->nr_hw_float_const++; if (!emit_def_const( emit, SVGA3D_CONST_TYPE_FLOAT, idx, 0, 0, 0, 1 )) @@ -568,7 +568,7 @@ create_zero_immediate( struct svga_shader_emitter *emit ) static INLINE boolean create_loop_const( struct svga_shader_emitter *emit ) { - unsigned idx = emit->nr_hw_const++; + unsigned idx = emit->nr_hw_int_const++; if (!emit_def_const( emit, SVGA3D_CONST_TYPE_INT, idx, 255, /* iteration count */ @@ -586,7 +586,7 @@ create_loop_const( struct svga_shader_emitter *emit ) static INLINE boolean create_sincos_consts( struct svga_shader_emitter *emit ) { - unsigned idx = emit->nr_hw_const++; + unsigned idx = emit->nr_hw_float_const++; if (!emit_def_const( emit, SVGA3D_CONST_TYPE_FLOAT, idx, -1.5500992e-006f, @@ -596,7 +596,7 @@ create_sincos_consts( struct svga_shader_emitter *emit ) return FALSE; emit->sincos_consts_idx = idx; - idx = emit->nr_hw_const++; + idx = emit->nr_hw_float_const++; if (!emit_def_const( emit, SVGA3D_CONST_TYPE_FLOAT, idx, -0.020833334f, @@ -617,7 +617,7 @@ create_arl_consts( struct svga_shader_emitter *emit ) for (i = 0; i < emit->num_arl_consts; i += 4) { int j; - unsigned idx = emit->nr_hw_const++; + unsigned idx = emit->nr_hw_float_const++; float vals[4]; for (j = 0; j < 4 && (j + i) < emit->num_arl_consts; ++j) { vals[j] = emit->arl_consts[i + j].number; @@ -2407,7 +2407,7 @@ static boolean make_immediate( struct svga_shader_emitter *emit, float d, struct src_register *out ) { - unsigned idx = emit->nr_hw_const++; + unsigned idx = emit->nr_hw_float_const++; if (!emit_def_const( emit, SVGA3D_CONST_TYPE_FLOAT, idx, a, b, c, d )) -- 2.30.2
