(obj_dat.h and obj_mac.h are generated from the objects.txt change.) See upstream's 3c161d081e2d30549e787437d05ffa08122a5114. Also see upstream's 12048657a91b12e499d03ec9ff406b42aba67366 to give zlib a better comment.

OID information is generated via a series of perl scripts. In order, the full list of commands to run are: perl objects.pl objects.txt obj_mac.num ../../include/openssl/obj_mac.h perl obj_dat.pl ../../include/openssl/obj_mac.h obj_dat.h perl obj_xref.pl obj_mac.num obj_xref.txt > obj_xref.h objects.txt contains the list of all built-in OIDs. It is processed by objects.pl to output obj_mac.num and obj_mac.h. obj_mac.num is the list of NID values for each OID. This is an input/output parameter so NID values are stable across regenerations. obj_mac.h is the header which defines macros for all the built-in OIDs in C. obj_mac.h is read by obj_dat.pl to generate obj_dat.h. obj_dat.h contains the ASN1_OBJECTs corresponding to built-in OIDs themselves along with lookup tables for search by short name, OID, etc. obj_mac.num and obj_xref.txt are read by obj_xref.pl to generate obj_xref.h. obj_xref.txt links signature OIDs to corresponding public key algorithms and digests. obj_xref.h contains lookup tables for querying this information in both directions.
