2014-02-19convert to_supports_btraceTom Tromey2-3/+3
This adds a "self" argument to to_supports_btrace. Due to how one implementation of this method is shared with gdbserver this required a small change to gdbserver as well. 2014-02-19 Tom Tromey <tromey@redhat.com> * common/linux-btrace.c (linux_supports_btrace): Add "ops" argument. * common/linux-btrace.h (linux_supports_btrace): Update. * remote.c (remote_supports_btrace): Add "self" argument. * target-delegates.c: Rebuild. * target.c (target_supports_btrace): Remove. * target.h (struct target_ops) <to_supports_btrace>: Add target_ops argument. (target_supports_btrace): New define. 2014-02-19 Tom Tromey <tromey@redhat.com> * target.h (struct target_ops) <supports_btrace>: Add target_ops argument. (target_supports_btrace): Update.
2014-02-12update rsp-low commentsTom Tromey2-1/+38
This updates all the comments in rsp-low.[ch], now that the unification has been completed. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.c: Update comments. * common/rsp-low.h: Update comments.
2014-02-12replace convert_ascii_to_int with hex2binTom Tromey2-14/+0
convert_ascii_to_int is identical to hex2bin. This removes the former. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.c (convert_ascii_to_int): Remove. * common/rsp-low.h (convert_ascii_to_int): Don't declare. 2014-02-12 Tom Tromey <tromey@redhat.com> * ax.c (gdb_parse_agent_expr): Use hex2bin, not convert_ascii_to_int. * regcache.c (registers_to_string): Likewise. * remote-utils.c (decode_M_packet): Likewise. * server.c (process_serial_event): Likewise.
2014-02-12replace unhexify with hex2binTom Tromey2-21/+0
unhexify and hex2bin are identical, so this removes unhexify. The particular choice of which to keep was made on the basis of parallelism with the earlier patch that removed hexify. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.h (unhexify): Don't declare. * common/rsp-low.c (unhexify): Remove. 2014-02-12 Tom Tromey <tromey@redhat.com> * server.c (handle_query, handle_v_run): Use hex2bin, not unhexify. * tracepoint.c (cmd_qtdpsrc, cmd_qtdv, cmd_qtnotes): Likewise.
2014-02-12replace convert_int_to_ascii with bin2hexTom Tromey2-18/+0
convert_int_to_ascii is identical to bin2hex. This removes the former. In this case I made the choice of which to keep on the basis that I consider the name bin2hex to be superior to convert_int_to_ascii. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.h (convert_int_to_ascii): Don't declare. * common/rsp-low.c (convert_int_to_ascii): Remove. 2014-02-12 Tom Tromey <tromey@redhat.com> * ax.c (gdb_unparse_agent_expr): Use bin2hex, not convert_int_to_ascii. * regcache.c (registers_to_string, collect_register_as_string): Likewise. * remote-utils.c (look_up_one_symbol, relocate_instruction): Likewise. * server.c (process_serial_event): Likewise. * tracepoint.c (cmd_qtstatus, response_source, response_tsv) (cmd_qtbuffer, cstr_to_hexstr): Likewise.
2014-02-12replace hexify with bin2hexTom Tromey2-16/+0
This removes hexify in favor of bin2hex. The choice of which to keep was arbitrary. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.h (hexify): Don't declare. * common/rsp-low.c (hexify): Remove. 2014-02-12 Tom Tromey <tromey@redhat.com> * remote-utils.c (look_up_one_symbol, monitor_output): Use bin2hex, not hexify. * tracepoint.c (cmd_qtstatus): Likewise.
2014-02-12don't let hexify call strlenTom Tromey1-4/+0
hexify had the same issue as bin2hex; and the fix is the same. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.c (hexify): Never take strlen of argument. 2014-02-12 Tom Tromey <tromey@redhat.com> * remote-utils.c (monitor_output): Pass explicit length to hexify.
2014-02-12don't let bin2hex call strlenTom Tromey1-4/+0
Currently bin2hex may call strlen if the length argument is zero. This prevents some function unification; and also it seems cleaner to me not to have a special meaning for a zero length. 2014-02-12 Tom Tromey <tromey@redhat.com> * common/rsp-low.c (bin2hex): Never take strlen of argument. * remote.c (extended_remote_run, remote_rcmd) (remote_download_trace_state_variable, remote_save_trace_data) (remote_set_trace_notes): Update. * tracepoint.c (encode_source_string, tfile_write_status) (tfile_write_uploaded_tsv): Update.
2014-02-12move some rsp bits into rsp-low.hTom Tromey2-0/+347
This moves various low-level remote serial protocol bits into common/rsp-low.[ch]. This is as close to a pure move as possible. There are some redundancies remaining but those will be dealt with in a subsequent patch. Note that the two variants of remote_escape_output disagreed on the treatment of "*". On the theory that quoting cannot hurt but the absence possibly can, I chose the gdbserver variant to be the canonical one. 2014-02-12 Tom Tromey <tromey@redhat.com> * tracepoint.c: Include rsp-low.h. * remote.h (hex2bin, bin2hex, unpack_varlen_hex): Don't declare. * remote.c: Include rsp-low.h.

2014-02-12share "cell" codeTom Tromey2-0/+404
The "cell"-based printing code, like phex, was duplicated in both gdb and gdbserver. This patch merges the two implementations into a new file in common/. 2014-02-12 Tom Tromey <tromey@redhat.com> * utils.h: Include print-utils.h.

2014-01-22Add ARI (ok) marker for __func__ reference in common-utils.hJoel Brobecker1-1/+1
The ARI script flagged the use of the __func__ variable, which is normally not allowed (not defined in C90). However, this particular use is OK, as the reference is only made when __STDC_VERSION__ >= 199901L. So, add an "ARI:" comment to explicitly OK this use. gdb/ChangeLog: * common/common-utils.h: Add "ARI:" comment beside __func__ reference.
2014-01-22Expand documentation of common-utils.h::FUNCTION_NAMEJoel Brobecker1-1/+6
While looking at this macro, I noticed that it wasn't always necessarily defined. That prompted me to search the current sources to make sure that all uses were adequately protected, which they were. But to help prevent future uses to be made unprotected, this patch expands the current macro documentation a bit. gdb/ChangeLog: * common/common-utils.h (FUNCTION_NAME): Expand the macro's documentation a bit.

2014-01-16btrace, gdbserver: read branch trace incrementallyMarkus Metzger3-38/+101
Read branch trace data incrementally and extend the current trace rather than discarding it and reading the entire trace buffer each time. If the branch trace buffer overflowed, we can't extend the current trace so we discard it and start anew by reading the entire branch trace buffer. 2014-01-16 Markus Metzger <markus.t.metzger@intel.com> * common/linux-btrace.c (perf_event_read_bts, linux_read_btrace): Support delta reads.

2013-11-26Fix PR16193 - gdbserver aborts.Walfred Tedeschi1-7/+8
The MPX patch has broken the I386_XSTATE_SIZE macro. For AVX machines, it ends up returning I386_XSTATE_SSE_SIZE. Where it first reads I386_XSTATE_AVX_SIZE, it should have read I386_XSTATE_AVX: #define I386_XSTATE_SIZE(XCR0) \ (((XCR0) & I386_XSTATE_BNDCFG) != 0 ? I386_XSTATE_BNDCFG_SIZE \ : (((XCR0) & I386_XSTATE_BNDREGS) != 0 ? I386_XSTATE_BNDCFG_SIZE \ - : (((XCR0) & I386_XSTATE_AVX_SIZE) != 0 ? I386_XSTATE_AVX_SIZE \ + : (((XCR0) & I386_XSTATE_AVX) != 0 ? I386_XSTATE_AVX_SIZE \ : I386_XSTATE_SSE_SIZE))) The patch goes a step further and improves readability of the macro, by adding a couple other auxiliary macros. 2013-11-26 Walfred Tedeschi <walfred.tedeschi@intel.com> * i386-xstate.h (I386_XSTATE_MPX): New Macro.

2013-11-08introduce common.m4Tom Tromey1-0/+38
It has bothered me for a while that files in common/ use macros defined via autoconf checks, but rely on each configure.ac doing the proper checks independently. This patch introduces common/common.m4 which consolidates the checks assumed by code in common. The rule I propose is that if something is needed or used by common, it should be checked for by common.m4. However, if the check is also needed by gdb or gdbserver, then it should be duplicated there. Built and regtested on x86-64 Fedora 18 (though this is hardly the most strenuous case) and using the Fedora 18 mingw cross compilers. I also examined the config.in diffs to ensure that symbols did not go missing. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4. * common/common.m4: New file. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4, codeset.m4. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON.
2013-10-25infrun debug output: print enum gdb_signal symbol names instead of POSIX ↵Pedro Alves2-1/+14
signal names. The other day while debugging something related to random signals, I got confused with "set debug infrun 1" output, for it said: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 On GNU/Linux, 20 is SIGTSTP. For some reason, it took me a few minutes to realize that 20 is actually a GDB signal number, not a target signal number (duh!). In any case, I propose making GDB's output clearer here: One way would be to use gdb_signal_to_name, like already used elsewhere: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal SIGCHLD (20) but I think that might confuse someone too ("20? Why does GDB believe SIGCHLD is 20?"). So I thought of printing the enum string instead: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal GDB_SIGNAL_CHLD (20) Looking at a more complete infrun debug log, we had actually printed the (POSIX) signal name name a bit before: infrun: target_wait (-1, status) = infrun: 9300 [Thread 0x7ffff7fcb740 (LWP 9300)], infrun: status->kind = stopped, signal = SIGCHLD ... infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 So I'm now thinking that it'd be even better to make infrun output consistently use the enum symbol string, like so: infrun: clear_proceed_status_thread (Thread 0x7ffff7fca700 (LWP 25663)) infrun: clear_proceed_status_thread (Thread 0x7ffff7fcb740 (LWP 25659)) - infrun: proceed (addr=0xffffffffffffffff, signal=144, step=1) + infrun: proceed (addr=0xffffffffffffffff, signal=GDB_SIGNAL_DEFAULT, step=1) - infrun: resume (step=1, signal=0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGCHLD + infrun: status->kind = stopped, signal = GDB_SIGNAL_CHLD infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400700 - infrun: random signal 20 + infrun: random signal (GDB_SIGNAL_CHLD) infrun: random signal, keep going - infrun: resume (step=1, signal=20), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_CHLD), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGTRAP + infrun: status->kind = stopped, signal = GDB_SIGNAL_TRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400704 infrun: stepi/nexti infrun: stop_stepping GDB's signal numbers are public and hardcoded (see include/gdb/signals.h), so there's really no need to clutter the output with numeric values in some places while others not. Replacing the magic "144" with GDB_SIGNAL_DEFAULT in "proceed"'s debug output (see above) I think is quite nice. I posit that all this makes it clearer to newcomers that GDB has its own signal numbering (and that there must be some mapping going on).

2013-10-25Fix off-by-one errors in *scanf format strings.Gary Benson1-25/+41
In the first hunk, the format string was off-by-one for cmd, and cmd itself was larger than the maximum size required. cmd was reduced in size and the format string adjusted. In the second hunk, the format string was off-by-one for local_address, remote_address and extra, although the buffers for the two addresses were large enough for this not to matter. The specifiers for the two addresses was corrected, and a number of unused variables including extra were suppressed from parsing. In the third hunk, the format string was off-by-one for name, dependencies and status. This code was rewritten using strtok since dependencies can be arbitrarily long. gdb/ 2013-10-23 Gary Benson <gbenson@redhat.com> PR 16013 * common/linux-osdata.c (command_from_pid): Reduced size of cmd from 32 to 18.

2013-10-25Fix up a couple oddities in GDB's signal names and strings.Pedro Alves1-12/+12
- The Mach exception/signals escaped the TARGET_ -> GDB_ prefix change done a while ago, but there's no real reason for that. I grepped for TARGET_EXC and fixed all found, which unsurprisingly, means darwin-nat.c needed fixing. I think the change there is as obvious and trivial as it can get, so I'd be quite surprised if this broke anything there somehow. - GDB_SIGNAL_LAST's description string was unnecessarily inconsistent with the enum name.

2013-10-04Clean up ptid.h/ptid.c.Pedro Alves2-49/+37
The ptid_t contructors, accessors and predicates are documented in _three_ places, and each place uses a different wording. E.g, the descriptions in the .c file of the new ptid_lwp_p, ptid_tid_p weren't updated in the final revision like the descriptions in the .h file were. Clearly, switching to a style that has a single central description avoids such issues. Worse, some of the existing descriptions are plain wrong, such as: /* Attempt to find and return an existing ptid with the given PID, LWP, and TID components. If none exists, create a new one and return that. */ ptid_t ptid_build (int pid, long lwp, long tid); The function does nothing that complicated. It's just a simple constructor. So this gets rid of all the unnecessary descriptions, leaving only the ones near the function declarations in the header file, and fixes/clarifies those that remain. gdb/ 2013-10-04 Pedro Alves <palves@redhat.com> * common/ptid.c (null_ptid, minus_one_ptid, ptid_build) (pid_to_ptid, ptid_get_pid, ptid_get_lwp, ptid_get_tid) (ptid_equal, ptid_is_pid, ptid_lwp_p, ptid_tid_p): Replace describing comments with references to ptid.h. * common/ptid.h: Remove intro description of constructors, accessors and predicates.

2013-10-03Always run the PTRACE_O_TRACESYSGOOD tests even if PTRACE_O_TRACEFORK is not ↵Pedro Alves1-37/+46
supported. If enabling PTRACE_O_TRACEFORK fails, we never test for PTRACE_O_TRACESYSGOOD support. Before PTRACE_O_TRACESYSGOOD is checked, we have: /* First, set the PTRACE_O_TRACEFORK option. If this fails, we know for sure that it is not supported. */ ret = ptrace (PTRACE_SETOPTIONS, child_pid, (PTRACE_TYPE_ARG3) 0, (PTRACE_TYPE_ARG4) PTRACE_O_TRACEFORK); if (ret != 0) { ret = ptrace (PTRACE_KILL, child_pid, (PTRACE_TYPE_ARG3) 0, (PTRACE_TYPE_ARG4) 0); if (ret != 0) { warning (_("linux_check_ptrace_features: failed to kill child")); return; } ret = my_waitpid (child_pid, &status, 0); if (ret != child_pid) warning (_("linux_check_ptrace_features: failed " "to wait for killed child")); else if (!WIFSIGNALED (status)) warning (_("linux_check_ptrace_features: unexpected " "wait status 0x%x from killed child"), status); return; <<<<<<<<<<<<<<<<< } Note that early return. If PTRACE_O_TRACEFORK isn't supported, we're not checking PTRACE_O_TRACESYSGOOD. This didn't use to be a problem before the unification of this whole detection business in linux-ptrace.c. Before, the sysgood detection was completely separate: static void linux_test_for_tracesysgood (int original_pid) { int ret; sigset_t prev_mask; /* We don't want those ptrace calls to be interrupted. */ block_child_signals (&prev_mask); linux_supports_tracesysgood_flag = 0; ret = ptrace (PTRACE_SETOPTIONS, original_pid, 0, PTRACE_O_TRACESYSGOOD); if (ret != 0) goto out; linux_supports_tracesysgood_flag = 1; out: restore_child_signals_mask (&prev_mask); } So we need to get back the decoupling somehow. I think it's cleaner to split the seperate feature detections to separate functions. This patch does that. The new functions are named for their counterparts that existed before this code was moved to linux-ptrace.c. Note I've used forward declarations for the new functions to make the patch clearer, as otherwise the patch would look like I'd be adding a bunch of new code. A reorder can be done in a follow up patch. Tested on x86_64 Fedora 17. gdb/ 2013-10-03 Pedro Alves <palves@redhat.com> * common/linux-ptrace.c (linux_check_ptrace_features): Factor out the PTRACE_O_TRACESYSGOOD and PTRACE_O_TRACEFORK to separate functions.

2013-09-29gdb: btrace: fix build errors on older glibc buildsMike Frysinger1-2/+5
It is possible to have a build of glibc where SYS_perf_event_open is not defined (because when the glibc was compiled, the syscall did not exist), but have newer kernel headers installed so that linux/perf_event.h is available. In this setup, you get a build failure: ./common/linux-btrace.c: In function 'kernel_supports_btrace': ./common/linux-btrace.c:316:23: error: 'SYS_perf_event_open' undeclared (first use in this function) Update the ifdef check to also see if the syscall is available.
