Dave,
Please define a new enum tgsi_info.h for this as UTIL_FORMAT_XXX is not suited
(there is no value for doubles), for example
enum tgsi_opcode_type {
TGSI_TYPE_UNDETERMINED = -1, // e.g. TGSI_OPCODE_MOV
TGSI_TYPE_VOID = 0
TGSI_TYPE_FLOAT,
TGSI_TYPE_INT,
TGSI_TYPE_UINT,
TGSI_TYPE_DOUBLE,
};
Jose
