--set-spec-const-default-value "<spec id>:<default value> ..."
Set the default values of the specialization constants with
<spec id>-<default value> pairs specified in a double-quoted
string. <spec id>-<default value> pairs must be separated by
<spec id>:<default value> pairs specified in a double-quoted
string. <spec id>:<default value> pairs must be separated by
blank spaces, and in each pair, spec id and default value must
be separated with colon ':' without any blank spaces in between.
e.g.: --set-spec-const-default-value "1:100 2:400"
