To disable that one function and use the default C implementation instead,
I think this would work:
Modify Mesa/src/X86/x86.c in the gl_init_x86_asm_transforms() function:
void gl_init_x86_asm_transforms( void )
{
#ifdef USE_X86_ASM
void *save = gl_transform_tab[0][3][MATRIX_3D_NO_ROT]; /* save C function */
DECLARE_XFORM_GROUP( x86, 2, raw )
DECLARE_XFORM_GROUP( x86, 3, raw )
DECLARE_XFORM_GROUP( x86, 4, raw )
DECLARE_XFORM_GROUP( x86, 2, masked )
DECLARE_XFORM_GROUP( x86, 3, masked )
DECLARE_XFORM_GROUP( x86, 4, masked )
extern GLvector4f * _ASMAPI gl_x86_cliptest_points4( GLvector4f *clip_vec,
GLvector4f *proj_vec,
GLubyte clipMask[],
GLubyte *orMask,
GLubyte *andMask );
ASSIGN_XFORM_GROUP( x86, 0, 2, raw )
ASSIGN_XFORM_GROUP( x86, 0, 3, raw )
ASSIGN_XFORM_GROUP( x86, 0, 4, raw )
ASSIGN_XFORM_GROUP( x86, CULL_MASK_ACTIVE, 2, masked )
ASSIGN_XFORM_GROUP( x86, CULL_MASK_ACTIVE, 3, masked )
ASSIGN_XFORM_GROUP( x86, CULL_MASK_ACTIVE, 4, masked )
gl_transform_tab[0][3][MATRIX_3D_NO_ROT] = save; /* restore C function */
...
...
It'll generate a warning, but it should work.
Have you tried building Mesa without any X86 code?
