971
972 GDB targets (*-tdep.c) can register an interest in a specific
973 architecture. Other GDB components can register a need to maintain
974 per-architecture data.
975
976 The mechanisms below ensures that there is only a loose connection
977 between the set-architecture command and the various GDB

979 to maintain architecture specific data with gdbarch.
980
981 Pragmatics:
982
983 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
984 didn't scale.
985
986 The more traditional mega-struct containing architecture specific
987 data for all the various GDB components was also considered. Since
0fa6923a 988 GDB is built from a variable number of (fairly independent)
104c1213

989 components it was determined that the global aproach was not

1001 The INIT function takes two parameters: INFO which contains the

1010 The ARCHES parameter is a linked list (sorted most recently used)
1011 of all the previously created architures for this architecture
1012 family. The (possibly NULL) ARCHES->gdbarch can used to access
1013 values from the previously selected architecture for this
