[Dri-devel] Glide hacking

[Jacek <jp...@in...>]

In file: xc/lib/GL/mesa/src/drv/tdfx/tdfx_tris.c

there are calls: fxMesa->Glide.grDrawTriangle( a, b, c );

grDrawTriangle is probably defined in:

glide3x/h3/glide3/src/gdraw.c

and used code is:

GR_BEGIN_NOFIFOCHECK("grDrawTriangle",92);
TRISETUP(a, b, c);
GR_END();

GR_BEGIN_NOFIFOCHECK is:

GR_DCL_GC			- set gc value (few asm lines)
GR_DCL_HW			- set hw value 
GR_DEBUG_DCL(name, level)	- empty
FXUNUSED(hw)			- no idea (can't find definition yet)

TRISETUP is: (gc->triSetupProc)(gc, a, b, c)

GR_END is: {GR_CHECK_SIZE(); GR_TRACE_EXIT(myName);}  - asserts


Reading Glide source is crazy, but let's say I will complete grDrawTriangle
function as few simple lines of code (still with Glide calls). Could I put
these lines in tdfx_tris.c? Will it work, if all other functions will use
fxMesa->Glide stuff?
