/* TODO:
* Fragment Program Stuff:
* -----------------------------------------------------
- * - How does negating on SWZ work?? If any of the components have a -,
- * negate?
- * - how does thing like 'foo[N]' work in src registers?
*
* - things from Michal's email
* + overflow on atoi
* + not-overflowing floats (don't use parse_integer..)
- *
- * + fix multiple cases in switches, that might change
- * (these are things that are #defined to the same value, but occur
- * only on fp or vp's, which funkifies the switch statements)
- * - STATE_TEX_* STATE_CLIP_PLANE, etc and PRECISION_HINT_FASTEST/
- * PositionInvariant
- *
+ * + can remove range checking in arbparse.c
+ *
* - check all limits of number of various variables
* + parameters
- * + modelview matrix number
*
* - test! test! test!
*
* Vertex Program Stuff:
* -----------------------------------------------------
- * - Add in cases for vp attribs
- * + VERTEX_ATTRIB_MATRIXINDEX -- ??
- * + VERTEX_ATTRIB_GENERIC
- * * Test for input alias error --> bleh!
- *
- * - ARRAY_INDEX_RELATIVE
+ * - Optimize param array usage and count limits correctly, see spec,
+ * section 2.14.3.7
+ * + Record if an array is reference absolutly or relatively (or both)
+ * + For absolute arrays, store a bitmap of accesses
+ * + For single parameters, store an access flag
+ * + After parsing, make a parameter cleanup and merging pass, where
+ * relative arrays are layed out first, followed by abs arrays, and
+ * finally single state.
+ * + Remap offsets for param src and dst registers
+ * + Now we can properly count parameter usage
+ *
+ * - Multiple state binding errors in param arrays (see spec, just before
+ * section 2.14.3.3)
* - grep for XXX
*
* Mesa Stuff
* -----------------------------------------------------
+ * - User clipping planes vs. PositionInvariant
+ * - Is it sufficient to just multiply by the mvp to transform in the
+ * PositionInvariant case? Or do we need something more involved?
+ *
* - vp_src swizzle is GLubyte, fp_src swizzle is GLuint
* - fetch state listed in program_parameters list
* + WTF should this go???
*
* Cosmetic Stuff
* -----------------------------------------------------
- * - fix compiler warnings
* - remove any leftover unused grammer.c stuff (dict_ ?)
* - fix grammer.c error handling so its not static
* - #ifdef around stuff pertaining to extentions
*
* Outstanding Questions:
* -----------------------------------------------------
- * - palette matrix? do we support this extension? what is the extention?
+ * - ARB_matrix_palette / ARB_vertex_blend -- not supported
+ * what gets hacked off because of this:
+ * + VERTEX_ATTRIB_MATRIXINDEX
+ * + VERTEX_ATTRIB_WEIGHT
+ * + MATRIX_MODELVIEW
+ * + MATRIX_PALETTE
+ *
* - When can we fetch env/local params from their own register files, and
* when to we have to fetch them into the main state register file?
* (think arrays)
*
* Grammar Changes:
* -----------------------------------------------------
- * - changed optional_exponent rule from:
- * " exponent .or .true .emit '1' .emit 0x00;\n"
- * to
- * " exponent .or .true .emit '1' .emit 0x00 .emit $;\n"
- *
- * - XXX: need to recognize "1" as a valid float ?
