From 46c1419c9342f68755636208307ee6bbd5c0cc24 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Mon, 3 Jul 2006 22:14:54 +0000 Subject: some minor simplifications (same as in r300 driver) since mesa's internally used swizzle and writemask flags are identical to the bits used on the hardware, use a macro to error out if these assumptions are no longer true. --- src/mesa/drivers/dri/r200/r200_vertprog.c | 40 +++++++++++++------------------ 1 file changed, 17 insertions(+), 23 deletions(-) (limited to 'src/mesa/drivers') diff --git a/src/mesa/drivers/dri/r200/r200_vertprog.c b/src/mesa/drivers/dri/r200/r200_vertprog.c index 9e651aa7d1..00c236e839 100644 --- a/src/mesa/drivers/dri/r200/r200_vertprog.c +++ b/src/mesa/drivers/dri/r200/r200_vertprog.c @@ -41,6 +41,19 @@ USE OR OTHER DEALINGS IN THE SOFTWARE. #include "program_instruction.h" #include "tnl/tnl.h" +#if SWIZZLE_X != VSF_IN_COMPONENT_X || \ + SWIZZLE_Y != VSF_IN_COMPONENT_Y || \ + SWIZZLE_Z != VSF_IN_COMPONENT_Z || \ + SWIZZLE_W != VSF_IN_COMPONENT_W || \ + SWIZZLE_ZERO != VSF_IN_COMPONENT_ZERO || \ + SWIZZLE_ONE != VSF_IN_COMPONENT_ONE || \ + WRITEMASK_X != VSF_FLAG_X || \ + WRITEMASK_Y != VSF_FLAG_Y || \ + WRITEMASK_Z != VSF_FLAG_Z || \ + WRITEMASK_W != VSF_FLAG_W +#error Cannot change these! +#endif + #define SCALAR_FLAG (1<<31) #define FLAG_MASK (1<<31) #define OP_MASK (0xf) /* we are unlikely to have more than 15 */ @@ -137,16 +150,10 @@ static GLboolean r200VertexProgUpdateParams(GLcontext *ctx, struct r200_vertex_p return GL_TRUE; } -static unsigned long t_dst_mask(GLuint mask) +static __inline unsigned long t_dst_mask(GLuint mask) { - unsigned long flags = 0; - - if(mask & WRITEMASK_X) flags |= VSF_FLAG_X; - if(mask & WRITEMASK_Y) flags |= VSF_FLAG_Y; - if(mask & WRITEMASK_Z) flags |= VSF_FLAG_Z; - if(mask & WRITEMASK_W) flags |= VSF_FLAG_W; - - return flags; + /* WRITEMASK_* is equivalent to VSF_FLAG_* */ + return mask & VSF_FLAG_ALL; } static unsigned long t_dst(struct prog_dst_register *dst) @@ -220,19 +227,6 @@ static unsigned long t_src_class(enum register_file file) static __inline unsigned long t_swizzle(GLubyte swizzle) { /* this is in fact a NOP as the Mesa SWIZZLE_* are all identical to VSF_IN_COMPONENT_* */ -/* - switch(swizzle){ - case SWIZZLE_X: return VSF_IN_COMPONENT_X; - case SWIZZLE_Y: return VSF_IN_COMPONENT_Y; - case SWIZZLE_Z: return VSF_IN_COMPONENT_Z; - case SWIZZLE_W: return VSF_IN_COMPONENT_W; - case SWIZZLE_ZERO: return VSF_IN_COMPONENT_ZERO; - case SWIZZLE_ONE: return VSF_IN_COMPONENT_ONE; - default: - fprintf(stderr, "problem in %s", __FUNCTION__); - exit(0); - } -*/ return swizzle; } @@ -713,7 +707,7 @@ static GLboolean r200_translate_vertex_program(struct r200_vertex_program *vp) o_inst->src1 = ZERO_SRC_0; o_inst->src2 = UNUSED_SRC_1; goto next; - + case OPCODE_MAD: hw_op=(src[0].File == PROGRAM_TEMPORARY && src[1].File == PROGRAM_TEMPORARY && -- cgit v1.2.3
