Additionally it attempts to minimize the need - * for execute-time fixup of these vertex lists, allowing them to be - * cached on hardware. - * - * There are still some circumstances where this can be thwarted, for - * example by building a list that consists of one very long primitive - * (eg Begin(Triangles), 1000 vertices, End), and calling that list - * from inside a different begin/end object (Begin(Lines), CallList, - * End). - * - * In that case the code will have to replay the list as individual - * commands through the Exec dispatch table, or fix up the copied - * vertices at execute-time. - * - * The other case where fixup is required is when a vertex attribute - * is introduced in the middle of a primitive. Eg: - * Begin(Lines) - * TexCoord1f() Vertex2f() - * TexCoord1f() Color3f() Vertex2f() - * End() - * - * If the current value of Color isn't known at compile-time, this - * primitive will require fixup. - * - * - * The list compiler currently doesn't attempt to compile lists - * containing EvalCoord or EvalPoint commands. On encountering one of - * these, compilation falls back to opcodes. - * - * This could be improved to fallback only when a mix of EvalCoord and - * Vertex commands are issued within a single primitive. - */ - - -#include "glheader.h" -#include "context.h" -#include "dlist.h" -#include "enums.h" -#include "macros.h" -#include "api_validate.h" -#include "api_arrayelt.h" -#include "vtxfmt.h" -#include "t_save_api.h" -#include "dispatch.h" - -/* - * NOTE: Old 'parity' issue is gone, but copying can still be - * wrong-footed on replay. - */ -static GLuint _save_copy_vertices( GLcontext *ctx, - const struct tnl_vertex_list *node ) -{ - TNLcontext *tnl = TNL_CONTEXT( ctx );
