* Cosmetic Stuff
* -----------------------------------------------------
- * - fix compiler warnings
+ * - 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
* " exponent .or .true .emit '1' .emit 0x00 .emit $;\n"
*
* - XXX: need to recognize "1" as a valid float ?
+ * - XXX: this fails:
+ * "MUL result.color.xyz, R0, program.local[35] ;"
+ * but this works:
+ * "MUL result.color.primary.xyz, R0, program.local[35] ;"
+ * -> see progs/tests/arbvptorus.c
+ *
+ * - changed "progLocalParam\n" changed from:
+ * " \"local\" .emit PROGRAM_PARAM_LOCAL .and lbracket .and progLocalParamNum
+ * .and rbracket;\n"
+ * to:
+ * " \"local\" .emit PROGRAM_PARAM_LOCAL .and lbracket .and progLocalParamNum
+ * .and rbracket .emit 0x00;\n"
+ * so we can distinguish between the progLocalParam and progLocalParams rules
+ *
+ * - made the same change as above to the progEnvParam rule
