From: Roland Scheidegger Date: Wed, 30 Aug 2006 13:44:31 +0000 (+0000) Subject: Minor r200 vertex program cleanups. Remove disabled leftovers from r300 vertex progra... X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a974aaaa3e77a04375e5a9ddd413507596bd743e;p=mesa.git Minor r200 vertex program cleanups. Remove disabled leftovers from r300 vertex program code. Fix authors. Correct slightly wrong check to determine if ran out of temps. Simplify check to determine if ran out of max instructions. Correctly report used native temps. Always kick off program translation when ProgramStringNotify is called (otherwise the reported native resources used queried might be wrong). --- diff --git a/src/mesa/drivers/dri/r200/r200_context.h b/src/mesa/drivers/dri/r200/r200_context.h index 0f646bf30b9..b7ee33aa6c9 100644 --- a/src/mesa/drivers/dri/r200/r200_context.h +++ b/src/mesa/drivers/dri/r200/r200_context.h @@ -102,7 +102,7 @@ typedef void (*r200_point_func)( r200ContextPtr, struct r200_vertex_program { struct gl_vertex_program mesa_program; /* Must be first */ int translated; - VERTEX_SHADER_INSTRUCTION instr[R200_VSF_MAX_INST + 2]; + VERTEX_SHADER_INSTRUCTION instr[R200_VSF_MAX_INST + 3]; int pos_end; int inputs[VERT_ATTRIB_MAX]; int native; diff --git a/src/mesa/drivers/dri/r200/r200_vertprog.c b/src/mesa/drivers/dri/r200/r200_vertprog.c index 4d87d2ecf0b..8714cc7aa28 100644 --- a/src/mesa/drivers/dri/r200/r200_vertprog.c +++ b/src/mesa/drivers/dri/r200/r200_vertprog.c @@ -28,6 +28,7 @@ USE OR OTHER DEALINGS IN THE SOFTWARE. /* * Authors: * Aapo Tahkola + * Roland Scheidegger */ #include "glheader.h" #include "macros.h" @@ -432,41 +433,6 @@ static GLboolean r200_translate_vertex_program(struct r200_vertex_program *vp) int u_temp_i = R200_VSF_MAX_TEMPS - 1; struct prog_src_register src[3]; -#if 0 - if (getenv("R300_VP_SAFETY")) { - WARN_ONCE("R300_VP_SAFETY enabled.\n"); - - vpi = malloc((mesa_vp->Base.NumInstructions + VSF_MAX_FRAGMENT_TEMPS) * sizeof(struct prog_instruction)); - memset(vpi, 0, VSF_MAX_FRAGMENT_TEMPS * sizeof(struct prog_instruction)); - - for (i=0; i < VSF_MAX_FRAGMENT_TEMPS; i++) { - vpi[i].Opcode = OPCODE_MOV; - vpi[i].StringPos = 0; - vpi[i].Data = 0; - - vpi[i].DstReg.File = PROGRAM_TEMPORARY; - vpi[i].DstReg.Index = i; - vpi[i].DstReg.WriteMask = WRITEMASK_XYZW; - vpi[i].DstReg.CondMask = COND_TR; - - vpi[i].SrcReg[0].File = PROGRAM_STATE_VAR; - vpi[i].SrcReg[0].Index = 0; - vpi[i].SrcReg[0].Swizzle = MAKE_SWIZZLE4(SWIZZLE_ONE, SWIZZLE_ONE, SWIZZLE_ONE, SWIZZLE_ONE); - } - - memcpy(&vpi[i], mesa_vp->Base.Instructions, mesa_vp->Base.NumInstructions * sizeof(struct prog_instruction)); - - free(mesa_vp->Base.Instructions); - - mesa_vp->Base.Instructions = vpi; - - mesa_vp->Base.NumInstructions += VSF_MAX_FRAGMENT_TEMPS; - vpi = &mesa_vp->Base.Instructions[mesa_vp->Base.NumInstructions-1]; - - assert(vpi->Opcode == OPCODE_END); - } -#endif - /* FIXME: is changing the prog safe to do here?
