This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Nowadays, GDB calls target_can_download_tracepoint at the entry of
download_tracepoint_locations, which is called by.
update_global_location_list. Sometimes, it is not needed to call
target_can_download_tracepoint at all because there is no tracepoint
created. In remote target, target_can_download_tracepoint send
qTStatus to the remote in order to know whether tracepoint can be
downloaded or not. This means some redundant qTStatus packets are
sent.
This patch is to teach GDB to call target_can_download_tracepoint
lazily, only on the moment there are tracepoint to download.
gdb.perf/single-step.exp (with a local patch to measure RSP packets)
shows the number of RSP packets is reduced because there is no
tracepoint at all, so GDB doesn't send qTStatus any more.
# of RSP packets
original patched
single-step rsp 1000 7000 6000
single-step rsp 2000 14000 12000
single-step rsp 3000 21000 18000
single-step rsp 4000 28000 24000

* breakpoint.c (download_tracepoint_locations): New local
can_download_tracepoint. Check the result of
target_can_download_tracepoint and save it in
can_download_tracepoint if there are tracepoints to download.
* linux-nat.h (enum tribool): Move it to ...
* common/common-types.h: ... here.
This introduces common-types.h. This file defines various standard
types used by gdb and gdbserver.
Currently these types are conditionally defined based on GDBSERVER.
The long term goal is to remove all such tests; however, this is
difficult as currently gdb uses definitions from BFD. In the meantime
this is still a step in the right direction.
gdb/ChangeLog:
* common/common-types.h: New file.
* Makefile.in (HFILES_NO_SRCDIR): Add common/common-types.h.
* common/common-defs.h: Include common-types.h.
* defs.h (gdb_byte, CORE_ADDR, CORE_ADDR_MAX, LONGEST)
(ULONGEST): Remove.
gdb/gdbserver/ChangeLog:
* server.h: Add static assertion.
(gdb_byte, CORE_ADDR, LONGEST, ULONGEST): Remove.
