*
* 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 ?
- * - 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
