2013-10-11Document the -catch-assert and -catch-exception new GDB/MI commands.Joel Brobecker1-0/+99
This patch adds documentation for the new GDB/MI commands "-catch-assert" and "-catch-exception", meant to provide the same functionality as the "catch assert", "catch exception" and "catch exception unhandled" CLI commands. In the GDB Manual, there was already a section for catchpoint comments, so that seemed like a natural place to document the new commands. But commands related to a given concept seem to have traditionally been organized alphabetically, and I didn't want future commands to break down logical pairing of various commands. For instance, "-catch-load" and "-catch-unload" are quite "distant" from each other, and it is easy to imagine a new comment which would alphabetically fall in between, causing them to be separated. So I introduced subsections to prevent that from happening. gdb/ChangeLog: * NEWS: Add entry documenting the new "-catch-assert" and "-catch-exception" GDB/MI commands. gdb/doc/ChangeLog: * gdb.texinfo (Shared Library GDB/MI Catchpoint Commands): New subsection inside which the "-catch-load" and "-catch-unload" commands documentation is now placed. (Ada Exception GDB/MI Catchpoint Commands): New subsection documenting the "-catch-assert" and "-catch-exception" new GDB/MI commands.

2013-10-10Rename "set/show remotebaud" command into "set/show serial baud"Joel Brobecker2-4/+9
This patch renames the "set/show remotebaud" commands into "set/show serial baud", and moves its implementation into serial.c. It also moves the "baud_rate" global from top.c to serial.c, where the new code is being added (the alternative was to add an include of target.h). And to facilitate the transition to the new setting name, this patch also preserves the old commands, and marks them as deprecated to alert the users of the change. gdb/ChangeLog: * cli/cli-cmds.c (show_baud_rate): Moved to serial.c as serial_baud_show_cmd. (_initialize_cli_cmds): Delete the code creating the "set/show remotebaud" commands. * serial.c (baud_rate): Move here from top.c. (serial_baud_show_cmd): Move here from cli/cli-cmds.c.

2013-10-07This patch adds a new convenience variable called "$_exitsignal", whichSergio Durigan Junior2-2/+63
will hold the signal number when the inferior terminates due to the uncaught signal. I've made modifications on infrun.c:handle_inferior_event such that $_exitcode gets cleared when the inferior signalled, and vice-versa. This assumption was made because the variables are mutually exclusive, i.e., when the inferior terminates because of an uncaught signal it is not possible for it to return. I have also made modifications such that when a corefile is loaded, $_exitsignal gets set to the uncaught signal that "killed" the inferior, and $_exitcode is cleared. The patch also adds a NEWS entry, documentation bits, and a testcase. The documentation entry explains how to use $_exitsignal and $_exitcode in a GDB script, by making use of the new $_isvoid convenience function. gdb/ 2013-10-06 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS: Mention new convenience variable $_exitsignal. * corelow.c (core_open): Reset exit convenience variables.

2013-10-02Print registers not saved in the frame as "<not saved>" instead of ↵Pedro Alves2-4/+32
"<optimized out>". Currently, in some scenarios, GDB prints <optimized out> when printing outer frame registers. An <optimized out> register is a confusing concept. What this really means is that the register is call-clobbered, or IOW, not saved by the callee. This patch makes GDB say that instead. Before patch: (gdb) p/x $rax $1 = <optimized out> (gdb) info registers rax rax <optimized out> After patch: (gdb) p/x $rax $1 = <not saved> (gdb) info registers rax rax <not saved> However, if for some reason the debug info describes a variable as being in such a register (**), we still want to print <optimized out> when printing the variable. IOW, <not saved> is reserved for inspecting registers at the machine level. The patch uses lval_register+optimized_out to encode the not saved registers, and makes it so that optimized out variables always end up in !lval_register values. ** See <https://sourceware.org/ml/gdb-patches/2012-08/msg00787.html>. Current/recent enough GCC doesn't mark variables/arguments as being in call-clobbered registers in the ranges corresponding to function calls, while older GCCs did. Newer GCCs will just not say where the variable is, so GDB will end up realizing the variable is optimized out. frame_unwind_got_optimized creates not_lval optimized out registers, so by default, in most cases, we'll see <optimized out>. value_of_register is the function eval.c uses for evaluating OP_REGISTER (again, $pc, etc.), and related bits. It isn't used for anything else. This function makes sure to return lval_register values. The patch makes "info registers" and the MI equivalent use it too. I think it just makes a lot of sense, as this makes it so that when printing machine registers ($pc, etc.), we go through a central function. We're likely to need a different encoding at some point, if/when we support partially saved registers. Even then, I think value_of_register will still be the spot to tag the intention to print machine register values differently. value_from_register however may also return optimized out lval_register values, so at a couple places where we're computing a variable's location from a dwarf expression, we convert the resulting value away from lval_register to a regular optimized out value.

2013-09-16Based on the discussion at:Sergio Durigan Junior2-0/+68
<https://sourceware.org/ml/gdb-patches/2013-09/msg00301.html> <https://sourceware.org/ml/gdb-patches/2013-09/msg00383.html> This patch adds a new convenience function called $_isvoid, whose only purpose is to check whether an expression is void or not. This became necessary because the new convenience variable $_exitsignal (not yet approved) has a mutual exclusive behavior with $_exitcode, i.e., when one is "defined" (i.e., non-void), the other is cleared (i.e., becomes void). Doug wanted a way to identify which variable to use, and checking for voidness is the obvious solution. It is worth mentioning that my first attempt, after a conversation with Doug, was to actually implement a new $_isdefined() convenience function. I would do that (for convenience variables) by calling lookup_only_internalvar. However, I found a few problems: - Whenever I called $_isdefined ($variable), $variable became defined (with a void value), and $_isdefined always returned true. - Then, I tried to implement $_isdefined ("variable"), and do the "$" + "variable" inside GDB, thus making it impossible for GDB to create the convenience variable. However, it was hard to extract the string without having to mess with values and their idiossincrasies. Therefore, I decided to abandon this attempt (specially because I didn't want to spend too much time struggling with it). Anyway, after talking to Doug again we decided that it would be easier to implement $_isvoid, and this will probably help in cases like <http://stackoverflow.com/questions/3744554/testing-if-a-gdb-convenience-variable-is-defined>. I wrote a NEWS entry for it, and some new lines on the documentation. gdb/ 2013-09-16 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS: Mention new convenience function $_isvoid. * value.c (isvoid_internal_fn): New function.

2013-08-13introduce parallel modeTom Tromey2-6/+42
This introduces parallel mode for the test suite. It doesn't fully work yet in the sense that if you do a fully parallel run, you will encounter some file-name clashes, but this has to start somewhere, and it seemed best to add some infrastructure now, so that you can follow along and test subsequent patches if you care to. This patch has two parts. First, it checks for the GDB_PARALLEL variable. If this is set (say, on the runtest command line), then the test suite assumes "parallel mode". In this mode, files are put into a subdirectory named after the test. That is, for DIR/TEST.exp, the outputs are put into ./outputs/DIR/TEST/. This first part has various follow-on changes coming in subsequent patches. This is why the code in this patch also makes "temp" and "cache" directories. Second, this adds an "inotify" mode. If you have the inotifywait command (part of inotify-tools), you can set the GDB_INOTIFY variable. This will tell the test suite to watch for changes outside of the allowed output directories. This mode is useful for debugging the test suite, as it issues a report whenever a possibly parallel-unsafe file open is done. 2013-08-13 Tom Tromey <tromey@redhat.com> Yao Qi <yao@codesourcery.com> * lib/cache.exp (gdb_do_cache): Handle GDB_PARALLEL. * lib/gdb.exp: Handle GDB_PARALLEL.

2013-06-27Move comment on the 'stepping over resolver' mechanism to the internals manual.Pedro Alves2-0/+51
This whole comment is now a bit out of place. I looked into moving it to handle_inferior_event, close to where in_solib_dynsym_resolve_code is used, but then there are 3 such places. I then looked at fragmenting it, pushing bits closer to the definitions of in_solib_dynsym_resolve_code and gdbarch_skip_solib_resolver, but then we'd lose the main advantage which is the overview. In the end, I realized this can fit nicely as internals manual material. This could possibly be a subsection of a new "run control", or "source stepping" or "stepping" or some such a bit more general section, but we can do that when we have more related content... Even the "single stepping" section is presently empty... gdb/doc/ 2013-06-27 Pedro Alves <palves@redhat.com> * gdbint.texinfo (Algorithms) <Stepping over runtime loader dynamic symbol resolution code>: New section, based on infrun.c comment. gdb/ 2013-06-27 Pedro Alves <palves@redhat.com> * infrun.c: Remove comment describing the 'stepping over runtime loader dynamic symbol resolution code' mechanism; moved to gdbint.texinfo.

2013-06-24don't keep a gdb-specific dateTom Tromey2-5/+17
Right now there are two nightly commits to update a file in the tree with the current date. One commit is for BFD, one is for gdb. It seems unnecessary to me to do this twice. We can make do with a single such commit. This patch changes gdb in a minimal way to reuse the BFD date -- it extracts it from bfd/version.h and changes version.in to use the placeholder string "DATE" for those times when a date is wanted. I propose removing the cron job that updates the version on trunk, and then check in this patch. For release branches, we can keep the cron job, but just tell it to rewrite bfd/version.h. I believe this is a simple change in the crontab -- the script will work just fine on this file. This also moves version.in and version.h into common/, to reflect their shared status; and updates gdbserver to use version.h besides. * common/create-version.sh: New file. * Makefile.in (version.c): Use bfd/version.h, common/version.in, create-version.sh.

2013-05-23range stepping: gdbPedro Alves2-0/+56
This patch teaches GDB to take advantage of target-assisted range stepping. It adds a new 'r ADDR1,ADDR2' action to vCont (vCont;r), meaning, "step once, and keep stepping as long as the thread is in the [ADDR1,ADDR2) range". Rationale: When user issues the "step" command on the following line of source, a = b + c + d * e - a; GDB single-steps every single instruction until the program reaches a new different line. E.g., on x86_64, that line compiles to: 0x08048434 <+65>: mov 0x1c(%esp),%eax 0x08048438 <+69>: mov 0x30(%esp),%edx 0x0804843c <+73>: add %eax,%edx 0x0804843e <+75>: mov 0x18(%esp),%eax 0x08048442 <+79>: imul 0x2c(%esp),%eax 0x08048447 <+84>: add %edx,%eax 0x08048449 <+86>: sub 0x34(%esp),%eax 0x0804844d <+90>: mov %eax,0x34(%esp) 0x08048451 <+94>: mov 0x1c(%esp),%eax and the following is the RSP traffic between GDB and GDBserver: --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3c840408;thread:p2e13.2e13;core:1; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3e840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:42840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:47840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:49840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:4d840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2e13.2e13;core:0; IOW, a lot of roundtrips between GDB and GDBserver. If we add a new command to the RSP, meaning "keep stepping and don't report a stop until the program goes out of the [0x08048434, 0x08048451) address range", then the RSP traffic can be reduced down to: --> vCont;r8048434,8048451:p2db0.2db0;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2db0.2db0;core:1; As number of packets is reduced dramatically, the performance of stepping source lines is much improved. In case something is wrong with range stepping on the stub side, the debug info or even gdb, this adds a "set/show range-stepping" command to be able to turn range stepping off. gdb/ 2013-05-23 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_control_state) <may_range_step>: New field. * infcmd.c (step_once, until_next_command): Enable range stepping. * infrun.c (displaced_step_prepare): Disable range stepping.
