Bug fixes
Inconsistency in ABI generated for map
In CDT releases prior to 3.0.0, the ABI generated for std::map<K,V> was a list of structs in which the ABI for the inner struct included fields first and second, which is the same ABI that would be generated for std::pair<K,V>.
In CDT 3.0.0, the behavior of ABI generation for std::map<K,V> unintentionally changed such that the inner struct would sometimes use the fields key and value instead (depending on whether a std::map<K,V> or std::pair<K,V> was encountered first in the code scanned by the ABI generator). Additionally, if the ABI generation chose the version of the struct with fields key and value for the inner struct generated from a std::map<K,V>, then all other types involving std::pair<K,V> for different fields in the ABI would also use that version of the struct with fields key and value as opposed to version containing first and second that was intended.
This release fixes the bug introduced in CDT 3.0.0 to ensure that the inner struct generated in the ABI for std::map<K,V> is always the version that is compatible with the intended ABI of std::pair<K,V>: the version that contains first and second fields.
Enhancements
Make varints compile-time constructible
The varints unsigned_int and signed_int have been updated to be compile-time constructable to be available for compile time constant expressions.
