This is normally set up in the 44 @file{config/@var{target}.mt} file of your choice. If the name is not 45 defined, then all the architectures supported are included. 46 47 When BFD starts up, all the architectures are called with an 48 initialize method. It is up to the architecture back end to 49 insert as many items into the list of architectures as it wants to; 50 generally this would be one for each machine and one for the 51 default case (an item with a machine field of 0). 52 53 BFD's idea of an architecture is implemented in @file{archures.c}. 54 */ 55 56 /* 57 58 SUBSECTION 59 bfd_architecture 60 61 DESCRIPTION 62 This enum gives the object file's CPU architecture, in a 63 global sense---i.e., what processor family does it belong to? 64 Another field indicates which processor within 65 the family is in use.
