From 099e8ec54d4f7b9cd9ae3a481d6a6ae60f4590be Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 22 Jan 2010 15:41:08 -0700 Subject: mesa: re-implement _mesa_ProgramEnvParameter4fvARB() with memcpy() This is faster and ensures that NaN floats get stored properly. Before, NaN values (which might be used with UP2H, UP2US, UP4B and UP4UB) weren't getting stored properly with gcc -O3. This is the second part of the fix for the piglit fp-unpack-01 failure (bug 25973). --- src/mesa/shader/arbprogram.c | 33 ++++++++++++++++++++++++++++++--- 1 file changed, 30 insertions(+), 3 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/shader/arbprogram.c b/src/mesa/shader/arbprogram.c index eb537cd1b9..3cb2610950 100644 --- a/src/mesa/shader/arbprogram.c +++ b/src/mesa/shader/arbprogram.c @@ -561,6 +561,8 @@ _mesa_ProgramEnvParameter4fARB(GLenum target, GLuint index, } } + + /** * Set a program env parameter register. * \note Called from the GL API dispatcher. @@ -569,10 +571,35 @@ _mesa_ProgramEnvParameter4fARB(GLenum target, GLuint index, */ void GLAPIENTRY _mesa_ProgramEnvParameter4fvARB(GLenum target, GLuint index, - const GLfloat *params) + const GLfloat *params) { - _mesa_ProgramEnvParameter4fARB(target, index, params[0], params[1], - params[2], params[3]); + GET_CURRENT_CONTEXT(ctx); + ASSERT_OUTSIDE_BEGIN_END(ctx); + + FLUSH_VERTICES(ctx, _NEW_PROGRAM_CONSTANTS); + + if (target == GL_FRAGMENT_PROGRAM_ARB + && ctx->Extensions.ARB_fragment_program) { + if (index >= ctx->Const.FragmentProgram.MaxEnvParams) { + _mesa_error(ctx, GL_INVALID_VALUE, "glProgramEnvParameter4fv(index)"); + return; + } + memcpy(ctx->FragmentProgram.Parameters[index], params, + 4 * sizeof(GLfloat)); + } + else if (target == GL_VERTEX_PROGRAM_ARB /* == GL_VERTEX_PROGRAM_NV */ + && (ctx->Extensions.ARB_vertex_program || ctx->Extensions.NV_vertex_program)) { + if (index >= ctx->Const.VertexProgram.MaxEnvParams) { + _mesa_error(ctx, GL_INVALID_VALUE, "glProgramEnvParameter4fv(index)"); + return; + } + memcpy(ctx->VertexProgram.Parameters[index], params, + 4 * sizeof(GLfloat)); + } + else { + _mesa_error(ctx, GL_INVALID_ENUM, "glProgramEnvParameter4fv(target)"); + return; + } } -- cgit v1.2.3
