If we try to build a display list with just a glPrimitiveRestartNV() call, we'd crash because of a null GLvertexformat::PrimitiveRestartNV pointer. This change fixes that case.
The previous patch fixed the case of calling glPrimitiveRestartNV() inside a glBegin/End pair. --- src/mesa/main/dlist.c | 27 ++++++++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) diff --git a/src/mesa/main/dlist.c b/src/mesa/main/dlist.c index 9e817be..6e334fd 100644 --- a/src/mesa/main/dlist.c +++ b/src/mesa/main/dlist.c @@ -325,7 +325,8 @@ typedef enum OPCODE_STENCIL_FUNC_SEPARATE, OPCODE_STENCIL_OP_SEPARATE, OPCODE_STENCIL_MASK_SEPARATE, - + /* GL_NV_primitive_restart */ + OPCODE_PRIMITIVE_RESTART_NV, /* GL_ARB_shader_objects */ OPCODE_USE_PROGRAM, OPCODE_UNIFORM_1F, @@ -6095,6 +6096,24 @@ save_VertexAttrib4fvARB(GLuint index, const GLfloat * v) } static void GLAPIENTRY +save_PrimitiveRestartNV(void) +{ + /* Note: this is used when outside a glBegin/End pair in a display list */ + GET_CURRENT_CONTEXT(ctx); + Node *n; + ASSERT_OUTSIDE_SAVE_BEGIN_END_AND_FLUSH(ctx); + n = alloc_instruction(ctx, OPCODE_PRIMITIVE_RESTART_NV, 0); + if (n) { + /* nothing */ + } + if (ctx->ExecuteFlag) { + CALL_PrimitiveRestartNV(ctx->Exec, ()); + } + +} + + +static void GLAPIENTRY save_BlitFramebufferEXT(GLint srcX0, GLint srcY0, GLint srcX1, GLint srcY1, GLint dstX0, GLint dstY0, GLint dstX1, GLint dstY1, GLbitfield mask, GLenum filter) @@ -8670,6 +8689,10 @@ execute_list(struct gl_context *ctx, GLuint list) n[5].i, n[6].i, n[7].i, n[8].i, n[9].i, n[10].e)); break; + case OPCODE_PRIMITIVE_RESTART_NV: + CALL_PrimitiveRestartNV(ctx->Exec, ()); + break; + case OPCODE_USE_PROGRAM: CALL_UseProgram(ctx->Exec, (n[1].ui)); break; @@ -10460,6 +10483,8 @@ save_vtxfmt_init(GLvertexformat * vfmt) vfmt->VertexAttrib3fvARB = save_VertexAttrib3fvARB; vfmt->VertexAttrib4fARB = save_VertexAttrib4fARB; vfmt->VertexAttrib4fvARB = save_VertexAttrib4fvARB; + + vfmt->PrimitiveRestartNV = save_PrimitiveRestartNV; } -- 1.9.1 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
