This is normally set up in the 45 @file{config/@var{target}.mt} file of your choice. If the name is not 46 defined, then all the architectures supported are included. 47 48 When BFD starts up, all the architectures are called with an 49 initialize method. It is up to the architecture back end to 50 insert as many items into the list of architectures as it wants to; 51 generally this would be one for each machine and one for the 52 default case (an item with a machine field of 0). 53 54 BFD's idea of an architecture is implemented in @file{archures.c}. 55 */ 56 57 /* 58 59 SUBSECTION 60 bfd_architecture 61 62 DESCRIPTION 63 This enum gives the object file's CPU architecture, in a 64 global sense---i.e., what processor family does it belong to? 65 Another field indicates which processor within 66 the family is in use.
