We currently have two flushing commands 'flushregs' and 'maint flush-symbol-cache'. I'm planning to add at least one more so I thought it might be nice if we bundled these together into one place. And so I created the 'maint flush ' command prefix. Currently there are two commands: (gdb) maint flush symbol-cache (gdb) maint flush register-cache Unfortunately, even though both of the existing flush commands are maintenance commands, I don't know how keen we about deleting existing commands for fear of breaking things in the wild. So, both of the existing flush commands 'maint flush-symbol-cache' and 'flushregs' are still around as deprecated aliases to the new commands. I've updated the testsuite to use the new command syntax, and updated the documentation too. gdb/ChangeLog: * NEWS: Mention new commands, and that the old commands are now deprecated. * cli/cli-cmds.c (maintenanceflushlist): Define. * cli/cli-cmds.h (maintenanceflushlist): Declare. * maint.c (_initialize_maint_cmds): Initialise maintenanceflushlist. * regcache.c: Add 'cli/cli-cmds.h' include. (reg_flush_command): Add header comment. (_initialize_regcache): Create new 'maint flush register-cache' command, make 'flushregs' an alias. * symtab.c: Add 'cli/cli-cmds.h' include. (_initialize_symtab): Create new 'maint flush symbol-cache' command, make old command an alias. gdb/doc/ChangeLog: * gdb.texinfo (Symbols): Document 'maint flush symbol-cache'. (Maintenance Commands): Document 'maint flush register-cache'. gdb/testsuite/ChangeLog: * gdb.base/c-linkage-name.exp: Update to use new 'maint flush ...' commands. * gdb.base/killed-outside.exp: Likewise. * gdb.opt/inline-bt.exp: Likewise. * gdb.perf/gmonster-null-lookup.py: Likewise. * gdb.perf/gmonster-print-cerr.py: Likewise. * gdb.perf/gmonster-ptype-string.py: Likewise. * gdb.python/py-unwind.exp: Likewise.
