This is normally set up in the 43 @file{config/@var{target}.mt} file of your choice. If the name is not 44 defined, then all the architectures supported are included. 45 46 When BFD starts up, all the architectures are called with an 47 initialize method. It is up to the architecture back end to 48 insert as many items into the list of architectures as it wants to; 49 generally this would be one for each machine and one for the 50 default case (an item with a machine field of 0). 51 52 BFD's idea of an architecture is implemented in @file{archures.c}. 53 */ 54 55 /* 56 57 SUBSECTION 58 bfd_architecture 59 60 DESCRIPTION 61 This enum gives the object file's CPU architecture, in a 62 global sense---i.e., what processor family does it belong to? 63 Another field indicates which processor within 64 the family is in use.
