Set default values for spec const decorated by SpecId The pass instance is constructed with a map from spec id (uint32_t) to default values in string format. The default value strings will be parsed to numbers according to the target spec constant type. If the Spec Id decoration is found to be applied on multiple different target ids, that decoration instruction (OpDecorate or OpGroupDecorate) will be skipped. But other decoration instrucitons may still be processed.

Set default values for spec const decorated by SpecId The pass instance is constructed with a map from spec id (uint32_t) to default values in string format. The default value strings will be parsed to numbers according to the target spec constant type. If the Spec Id decoration is found to be applied on multiple different target ids, that decoration instruction (OpDecorate or OpGroupDecorate) will be skipped. But other decoration instrucitons may still be processed.
