2014-01-15Fix go32-nat.c build fallout from to_detach constification.Pedro Alves2-25/+11
The recent constification of to_detach missed updating the forward declaration of go32_detach, breaking the build: ../../src/gdb/go32-nat.c:387:1: error: conflicting types for 'go32_detach' ../../src/gdb/go32-nat.c:240:13: note: previous declaration of 'go32_detach' was here go32_detach is actually defined before it's ever used, making the forward declaration is unnecessary. So we can just remove it instead of updating it. While at it, remove all others in the same situation. Tested by building a djgpp gdb. gdb/ 2014-01-15 Pedro Alves <palves@redhat.com> * go32-nat.c (go32_open, go32_close, go32_attach, go32_detach) (go32_resume, go32_fetch_registers, store_register) (go32_store_registers, go32_prepare_to_store) (go32_xfer_memory, go32_files_info, go32_kill_inferior) (go32_create_inferior, go32_can_run, go32_terminal_init) (go32_terminal_inferior, go32_terminal_ours): Delete forward declarations.
2014-01-15introduce async_callback_ftypeTom Tromey2-1/+11
This introduces async_callback_ftype. This is needed for make-target-delegates to work properly, as it doesn't implement a real parser.

2014-01-14psymtab cleanup patch 3/3Doug Evans6-40/+62
This last patch removes "partial" from the names of expand_partial_symbol_names and map_partial_symbol_filenames. It also renames expand_partial_symbol_names to match the struct quick_symbol_functions "method" that it wraps: expand_symtabs_matching. This patch also adds two parameters to expand_symtabs_matching so that it can fully wrap the underlying quick_symbol_functions method. This makes it usable in more places. I thought of having a cover function that still had the same signature as the old expand_partial_symbol_names function, but I couldn't think of a good name, and it wasn't clear it was worth it anyway. * symfile.h (expand_symtabs_matching): Renamed from expand_partial_symbol_names. Update prototype. (map_symbol_filenames): Renamed from map_partial_symbol_filenames. * symfile.c (expand_symtabs_matching): Renamed from expand_partial_symbol_names. New args file_matcher, kind.

2014-01-14psymtab cleanup patch 2/3Doug Evans5-15/+45
This patch adds two typedefs: expand_symtabs_file_matcher_ftype expand_symtabs_symbol_matcher_ftype It also renames the NAME_MATCHER argument in expand_symtabs_matching. The function is named expand_symtabs_matching and it takes a name_matcher argument. Name of what? The symtab? A symbol? I made it SYMBOL_MATCHER to make it clearer. * symfile.h (expand_symtabs_file_matcher_ftype): New typedef. (expand_symtabs_symbol_matcher_ftype): New typedef.

2014-01-14psymtab cleanup patch 1/3Doug Evans6-35/+54
This is the first of a set of three patches to cleanup psymtab.c a bit. Basically, these two functions do not belong in psymtab.c: expand_partial_symbol_names, map_partial_symbol_filenames, and "partial" does not belong in the function name. This first patch moves them to a better location. The second patch adds some typedefs for function parameters to quick_symbol_functions.expand_symtabs_matching. The third patch removes "partial" from the function names and uses them in more places. * psymtab.c (expand_partial_symbol_names): Delete, moved to symfile.c. (map_partial_symbol_filenames): Ditto. * psymtab.h (expand_partial_symbol_names): Delete, moved to symfile.h. (map_partial_symbol_filenames): Ditto. * symfile.c (expand_partial_symbol_names): Moved here from psymtab.c.

2014-01-14Fix "is a record target open" checks.Pedro Alves7-12/+66
RECORD_IS_USED and record_full_open look at current_target.to_stratum to determine whether a record target is in use. This is wrong because arch_stratum is greater than record_stratum, so if an arch_stratum target is pushed, RECORD_IS_USED and record_full_open will miss it. To fix this, we can use the existing find_record_target instead, which looks up for a record stratum target across the target stack. Since that means exporting find_record_target in record.h, RECORD_IS_USED ends up redundant, so the patch eliminates it. That exercise then reveals other issues: - adjust_pc_after_break is gating record_full_... calls based on RECORD_IS_USED. But, record_full_ calls shouldn't be made when recording with the record-btrace target. So this adds a new record_full_is_used predicate to be used in that spot. - record_full_open says "Process record target already running", even if the recording target is record-btrace ("process record" is the original complete name of the record-full target). record_btrace_open only says "The process is already being recorded." and does not suggest "record stop", like record-full does. The patch factors out and merges that error to a new record_preopen function that all record targets call in their open routine. Tested on x86_64 Fedora 17. gdb/ 2014-01-14 Pedro Alves <palves@redhat.com> Tom Tromey <tromey@redhat.com> * infrun.c (use_displaced_stepping): Use find_record_target instead of RECORD_IS_USED.

2014-01-13Have regdat.sh always rewrite the output register filePatrick Palka2-13/+5
The rules for generating the output register files look like: amd64.c : $(srcdir)/../regformats/i386/amd64.dat $(regdat_sh) $(SHELL) $(regdat_sh) $(srcdir)/../regformats/i386/amd64.dat amd64.c According to this rule, if regdat.sh is newer than amd64.c, then regdat.sh shall be invoked on amd64.dat. According to regdat.sh, if the script determines that the output file amd64.c has not changed, then it will not overwrite the existing output file. This means that a subsequent invocation of make will trigger the above rule again as regdat.sh will be perpetually newer than amd64.c. This then shows up in the make output like so: /bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-linux.dat amd64-linux.c amd64-linux.c unchanged. /bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-avx-linux.dat amd64-avx-linux.c amd64-avx-linux.c unchanged. ... To fix this pathological behavior, it suffices to have regdat.sh unconditionally rewrite the output register file. On my machine, which has a regdat.sh file that is newer than some of the input register files, this change speeds up every invocation of make under gdb/ by about 5 seconds.

2014-01-12Split i386_stap_parse_special_token into smaller functionsSergio Durigan Junior2-244/+279
This patch reorganizes code on gdb/i386-tdep.c's SystemTap SDT probe support functions. Before it, the code to parse special operands on x86 lived in a single, big function. This patch creates 2 new functions that makes the code more organized and removes a few indentation levels (which is always good IMO). I haven't modified anything logical in the functions, i.e., there's still one latent bug on i386_stap_parse_special_token_triplet now. I will soon post a patch to fix this, and to also improve the readability of the two new functions. 2014-01-12 Sergio Durigan Junior <sergiodj@redhat.com> * i386-tdep.c (i386_stap_parse_special_token_triplet): New function, with code from i386_stap_parse_special_token.

2014-01-10Since upstream gcc has recently increased the function alignment onAndreas Arnez3-5/+12
S390, the dw2-dir-file-name test case fails in the first gdb_continue_to_breakpoint. Indeed, the breakpoint is now placed into the alignment gap *before* the actual function. This happens because the test case declares the respective "*_start" symbol as a "loose" label before the function definition, and the compiler inserts the alignment between that label and the function itself. The "*_start" symbols were only necessary because FUNC made the function static. The fix makes the functions extern instead, thus making the "*_start" labels unnecessary. testsuite/ 2014-01-10 Andreas Arnez <arnez@linux.vnet.ibm.com> Pedro Alves <palves@redhat.com> * gdb.dwarf2/dw2-dir-file-name.c (FUNC): Remove "*_start" symbol.

2014-01-09Handle the case of a remote target supporting target side commands, but not ↵Pedro Alves5-30/+111
on software breakpoints. Although we can tell upfront whether a remote target supports target side commands, we can only tell whether the target supports that in combination with a given breakpoint kind (software, hardware, watchpoints, etc.) when we go and try to insert such a breakpoint kind the first time. It's not desirable to make remote_insert_breakpoint simply return -1 in this case, because if the breakpoint was set in a shared library, insert_bp_location will assume that the breakpoint insertion failed because the library wasn't mapped in. insert_bp_location already handles errors/exceptions thrown from the target_insert_xxx methods, exactly so the backend can tell the user the detailed reason the insertion of hw breakpoints failed. But, in the case of software breakpoints, it discards the detailed error message. So the patch makes insert_bp_location use the error's message for SW breakpoints too, and, introduces a NOT_SUPPORTED_ERROR error code so that insert_bp_location doesn't confuse the error for failure due to a shared library disappearing. The result is: (gdb) c Warning: Cannot insert breakpoint 2: Target doesn't support breakpoints that have target side commands. 2014-01-09 Pedro Alves <palves@redhat.com> Hui Zhu <hui@codesourcery.com> PR gdb/16101 * breakpoint.c (insert_bp_location): Rename hw_bp_err_string to bp_err_string.

2014-01-08GDBserver: Discard previous queued events when GDB disconnects.Pedro Alves2-3/+12

2014-01-08[remote/gdbserver] Don't lose signals when reconnecting.Pedro Alves8-58/+429
Currently, when GDB connects in all-stop mode, GDBserver always responds to the status packet with a GDB_SIGNAL_TRAP, even if the program is actually stopped for some other signal. (gdb) tar rem ... ... (gdb) c Program received signal SIGUSR1, User defined signal 1. (gdb) disconnect (gdb) tar rem ... (gdb) c (Or a GDB crash instead of an explicit disconnect.) This results in the program losing that signal on that last continue, because gdb will tell the target to resume with no signal (to suppress the GDB_SIGNAL_TRAP, due to 'handle SISGTRAP nopass'), and that will actually suppress the real signal the program had stopped for (SIGUSR1). To fix that, I think we should make GDBserver report the real signal the thread had stopped for in response to the status packet: @item ? @cindex @samp{?} packet Indicate the reason the target halted. The reply is the same as for step and continue. But, that raises the question -- which thread are we reporting the status for? Due to how the RSP in all-stop works, we can only report one status. The status packet's response is a stop reply packet, so it includes the thread identifier, so it's not a problem packet-wise. However, GDBserver is currently always reporting the status for first thread in the thread list, even though that may well not be the thread that got the signal that caused the program to stop. So the next logical step would be to report the status for the last_ptid/last_status thread (the last event reported to gdb), if it's still around; and if not, fallback to some other thread. There's an issue on the GDB side with that, though... GDB currently always adds the thread reported in response to the status query as the first thread in its list. That means that if we start with e.g., (gdb) info threads 3 Thread 1003 ... * 2 Thread 1002 ... 1 Thread 1001 ... And reconnect: (gdb) disconnect (gdb) tar rem ... We end up with: (gdb) info threads 3 Thread 1003 ... 2 Thread 1001 ... * 1 Thread 1002 ... Not a real big issue, but it's reasonably fixable, by having GDB fetch/sync the thread list before fetching the status/'?', and then using the status to select the right thread as current on the GDB side. Holes in the thread numbers are squashed before/after reconnection (e.g., 2,3,5 becomes 1,2,3), but the order is preserved, which I think is both good, and good enough. However (yes, there's more...), the previous GDB that was connected might have had gdbserver running in non-stop mode, or could have left gdbserver doing disconnected tracing (which also forces non-stop), and if the new gdb/connection is in all-stop mode, we can end up with more than one thread with a signal to report back to gdb. As we can only report one thread/status (in the all-stop RSP variant; the non-stop variant doesn't have this issue), we get to do what we do at every other place we have this situation -- leave events we can't report right now as pending, so that the next resume picks them up. Note all this ammounts to a QoI change, within the existing framework. There's really no RSP change here. The only user visible change (other than that the signal is program is stopped at isn't lost / is passed to the program), is in "info program", that now can show the signal the program stopped for. Of course, the next resume will respect the pass/nopass setting for the signal in question. It'd be reasonable to have the initial connection tell the user the program was stopped with a signal, similar to when we load a core to debug, but I'm leaving that out for a future change. I think we'll need to either change how handle_inferior_event & co handle stop_soon, or maybe bypass them completely (like fork-child.c:startup_inferior) for that.
