2016-01-13Per-inferior/Inferior-qualified thread IDsPedro Alves1-3/+4
This commit changes GDB to track thread numbers per-inferior. Then, if you're debugging multiple inferiors, GDB displays "inferior-num.thread-num" instead of just "thread-num" whenever it needs to display a thread: (gdb) info inferiors Num Description Executable 1 process 6022 /home/pedro/gdb/tests/threads * 2 process 6037 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame 1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running) 1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running) 1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running) 2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running) 2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running) * 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running) (gdb) ... (gdb) thread 1.1 [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] (gdb) ... etc. You can still use "thread NUM", in which case GDB infers you're referring to thread NUM of the current inferior. The $_thread convenience var and Python's InferiorThread.num attribute are remapped to the new per-inferior thread number. It's a backward compatibility break, but since it only matters when debugging multiple inferiors, I think it's worth doing. Because MI thread IDs need to be a single integer, we keep giving threads a global identifier, _in addition_ to the per-inferior number, and make MI always refer to the global thread IDs. IOW, nothing changes from a MI frontend's perspective. Similarly, since Python's Breakpoint.thread and Guile's breakpoint-thread/set-breakpoint-thread breakpoint methods need to work with integers, those are adjusted to work with global thread IDs too. Follow up patches will provide convenient means to access threads' global IDs. To avoid potencially confusing users (which also avoids updating much of the testsuite), if there's only one inferior and its ID is "1", IOW, the user hasn't done anything multi-process/inferior related, then the "INF." part of thread IDs is not shown. E.g,.: (gdb) info inferiors Num Description Executable * 1 process 15275 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) add-inferior Added inferior 2 (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * NEWS: Mention that thread IDs are now per inferior and global thread IDs. * Makefile.in (SFILES): Add tid-parse.c.

2015-12-18Support software single step on ARM in GDBServerAntoine Tremblay1-3/+13
This patch teaches GDBServer how to software single step on ARM linux by sharing code with GDB. The arm_get_next_pcs function in GDB is now shared with GDBServer. So that GDBServer can use the function to return the possible addresses of the next PC. A proper shared context was also needed so that we could share the code, this context is described in the arm_get_next_pcs structure. Testing : No regressions, tested on ubuntu 14.04 ARMv7 and x86.

2015-10-21Implement breakpoint_kind_from_pc and sw_breakpoint_from_kind for ARM in ↵Antoine Tremblay1-1/+12
GDBServer. ARM can have multiple breakpoint types based on the instruction set it's currently in: arm, thumb or thumb2. GDBServer needs to know what breakpoint is to be inserted at location when inserting a breakpoint. This is handled by the breakpoint_kind_from_pc and sw_breakpoint_from_kind target ops introduced in a previous patch, this patch adds the arm_breakpoint_kind_from_pc and arm_sw_breakpoint_from_kind implementation so that the proper breakpoint type is returned based on the pc. Also in order to share some code with GDB a new file called arm.c have been introduced in arch/. While this file does not contain much yet future patches will add more to it thus the inclusion at this stage. No regressions on Ubuntu 14.04 on ARMv7 and x86.

2015-09-21Move instruction decoding into new arch/ directoryPierre Langlois1-2/+11
This patch moves the following functions into the arch/ common directory, in new files arch/aarch64-insn.{h,c}. They are prefixed with 'aarch64_': - aarch64_decode_adrp - aarch64_decode_b - aarch64_decode_cb - aarch64_decode_tb We will need them to implement fast tracepoints in GDBserver. For consistency, this patch also adds the 'aarch64_' prefix to static decoding functions that do not need to be shared right now.

2015-09-09Replace "struct continuation" mechanism by something more extensiblePedro Alves1-1/+1
This adds an object oriented replacement for the "struct continuation" mechanism, and converts the stepping commands (step, next, stepi, nexti) and the "finish" commands to use it. It adds a new thread "class" (struct thread_fsm) that contains the necessary info and callbacks to manage the state machine of a thread's execution command. This allows getting rid of some hacks. E.g., in fetch_inferior_event and normal_stop we no longer need to know whether a thread is doing a multi-step (e.g., step N). This effectively makes the intermediate_continuations unused -- they'll be garbage collected in a separate patch. (They were never a proper abstraction, IMO. See how fetch_inferior_event needs to check step_multi before knowing whether to call INF_EXEC_CONTINUE or INF_EXEC_COMPLETE.) The target async vs !async uiout hacks in mi_on_normal_stop go away too. print_stop_event is no longer called from normal_stop. Instead it is now called from within each interpreter's normal_stop observer. This clears the path to make each interpreter print a stop event the way it sees fit. Currently we have some hacks in common code to differenciate CLI vs TUI vs MI around this area. The "finish" command's FSM class stores the return value plus that value's position in the value history, so that those can be printed to both MI and CLI's streams. This fixes the CLI "finish" command when run from MI -- it now also includes the function's return value in the CLI stream: (gdb) ~"callee3 (strarg=0x400730 \"A string argument.\") at src/gdb/testsuite/gdb.mi/basics.c:35\n" ~"35\t}\n" +~"Value returned is $1 = 0\n" *stopped,reason="function-finished",frame=...,gdb-result-var="$1",return-value="0",thread-id="1",stopped-threads="all",core="0" -FAIL: gdb.mi/mi-cli.exp: CLI finish: check CLI output +PASS: gdb.mi/mi-cli.exp: CLI finish: check CLI output gdb/ChangeLog: 2015-09-09 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_OBS): Add thread-fsm.o. * breakpoint.c (handle_jit_event): Print debug output.

2015-08-24Prepare for gnulib updatePedro Alves1-1/+1
After the last gnulib import (Dec 2012), gnulib upstream started replacing mingw's 'struct timeval' with a version with 64-bit time_t, for POSIX compliance: commit f8e84098084b3b53bc6943a5542af1f607ffd477 Author: Bruno Haible <bruno@clisp.org> Date: Sat Jan 28 18:12:10 2012 +0100 sys_time: Override 'struct timeval' on some native Windows platforms. See: https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00372.html However, that results in conflicts with native Winsock2's 'select': select()'s argument http://sourceforge.net/p/mingw-w64/mailman/message/29610438/ ... and libiberty's timeval-utils.h timeval_add/timeval_sub, at the least. We don't really need the POSIX compliance, so this patch prepares us to simply not use gnulib's 'struct timeval' replacement once a more recent gnulib is imported, thus preserving the current behavior, by adding a sys/time.h wrapper header that undefs gnulib's replacements, and including that everywhere instead. The SIZE -> OSIZE change is necessary because newer gnulib's sys/time.h also includes windows.h/winsock2.h, which defines a conflicting SIZE symbol. Cross build-tested mingw-w64 32-bit and 64-bit. Regtested on x86_64 Fedora 20. gdb/ChangeLog: 2015-08-24 Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add common/gdb_sys_time.h. * common/gdb_sys_time.h: New file. * event-loop.c: Include gdb_sys_time.h instead of sys/time.h. * gdb_select.h: Likewise. * gdb_usleep.c: Likewise. * maint.c: Likewise. * mi/mi-main.c: Likewise. * mi/mi-parse.h: Likewise. * remote-fileio.c: Likewise. * remote-m32r-sdi.c: Likewise. * remote.c: Likewise. * ser-base.c: Likewise. * ser-pipe.c: Likewise. * ser-tcp.c: Likewise. * ser-unix.c: Likewise. * symfile.c: Likewise. * symfile.c: Likewise.

2015-08-13[D] Support looking up symbols in the current and imported modules.Iain Buclaw1-2/+2
In D, there is the notion of modules, and importing from one to the other, whether it is a basic, selective or renamed import declaration. module A; import X; void foo() { import Y : bar; } If the compiler emits DW_TAG_imported_declaration at the appropriate locations, then we can make use of what gdb stores in using_direct when performing nonlocal symbol lookups. gdb/ChangeLog * Makefile.in (SFILES): Add d-namespace.c. (COMMON_OBS): Add d-namespace.o. * d-lang.c (d_language_defn): Use d_lookup_symbol_nonlocal as the la_lookup_symbol_nonlocal callback function pointer. * d-lang.h (d_lookup_symbol_nonlocal): New declaration. (d_lookup_nested_symbol): New declaration. * d-namespace.c: New file.
2015-08-13[Ada] Add support for subprogram renamingsPierre-Marie de Rodat1-1/+2
Consider the following declaration: function Foo (I : Integer) return Integer renames Pack.Bar; As Foo is not materialized as a routine whose name is derived from Foo, GDB currently cannot use it: (gdb) print foo(0) No definition of "foo" in current context. However, compilers can emit DW_TAG_imported_declaration in order to materialize the fact that Foo is actually another name for Pack.Bar. This commit enhances the DWARF reader to record global renamings (it used to put global ones in a static block) and enhances the Ada engine to leverage this information during symbol lookup. gdb/ChangeLog: * ada-lang.c: Include namespace.h (aux_add_nonlocal_symbols): Fix a function name in comment.

2015-07-27Remove REMOTE_EXAMPLES from gdb/Makefile.inYao Qi1-2/+0
I happen to see REMOTE_EXAMPLES isn't used anywhere, so this patch removes it. REMOTE_EXAMPLES was added in the following commit in 1991, commit 86bbb439c8fa01fd55d6cbce102483a471ffd0c4 Author: John Gilmore <gnu@cygnus> Date: Fri May 3 19:57:13 1991 +0000 There should be a Makefile in the cvs main directory, configured for "./config.gdb none", so that things like "make tags" and "make tar" will work. and it was used like: TARFILES = ${TAGFILES_MAINDIR} ${OTHERS} ${REMOTE_EXAMPLES} However TARFILES was removed by the change latter in 1994, Tue Aug 16 15:24:03 1994 Jim Kingdon (kingdon@lioth.cygnus.com) * symtab.c (decode_line_1): If funfirstline and we get a non-LOC_BLOCK symbol (e.g. variable or type), then error(). * Makefile.in (TARFILES, NONSRC, SFILES_STAND, SFILES_KGDB): Remove; unused.

2015-07-17Move common aarch64 HW breakpoint/watchpoint code to nat/Yao Qi1-1/+5
When I look at test fails related to watchpoint on aarch64-linux, I find there are some code duplicates between GDB and GDBserver. This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}. The only change I do is about the dr_changed_t typedef, which was ULONGEST in GDB and 'unsigned long long' in GDBserver. Each bit of dr_changed_t represents a status of each HW breakpoint or watchpoint register, and the max number of HW breakpoint or watchpoint registers is 16, so the width of 'unsigned long long' is sufficient. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * Makefile.in (HFILES_NO_SRCDIR): Add nat/aarch64-linux-hw-point.h.

2015-03-13Remove HPUXJan Kratochvil1-12/+10
IIUC it is a pre-requisite for IPv6 support, some UNICes do not support getaddrinfo required for IPv6. But coincidentally such UNICes are no longer really supported by GDB. Therefore it was concluded we can remove all such UNICes and then we can implement IPv6 easily with getaddrinfo. In mail Re: getaddrinfo available on all GDB hosts?

This commits cleans up the gdb/breakpoint.c file and moves everything that is related to the 'catch syscall' command to the new file gdb/break-catch-syscall.c.

2015-02-27Add --enable-build-with-cxx configure switchPedro Alves1-7/+10
This new option, disabled by default for now, allows specifying whether to build GDB, GDBserver, and friends with a C++ (98/03) compiler. The name of the switch should be familiar to those who followed GCC's own C++ conversion process. . Adding -fpermissive to COMPILER in C++ mode (see the new build-with-cxx.m4 file) makes errors like these be warnings instead: gdb/infrun.c:6597:1: error: initializing argument 1 of ‘void sig_print_info(gdb_signal)’ [-fpermissive] sig_print_info (enum gdb_signal oursig) ^ gdb/infrun.c: In function ‘void do_restore_infcall_suspend_state_cleanup(void*)’: gdb/infrun.c:7164:39: error: invalid conversion from ‘void*’ to ‘infcall_suspend_state*’ [-fpermissive] restore_infcall_suspend_state (state); ^ so that the compiler carries on compiling the file. -Werror still catches the warnings, so nothing is lost, only our lifes are made easier by concentrating on getting other more important things out of the way first. There's no way to quiet those warnings. Until they're all fixed, when building in C++ mode, -Werror is disabled by default. . Adding -Wno-narrowing suppresses thousands of instances of this warning: gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1l’ from ‘LONGEST {aka long int}’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] gdb/arm-linux-tdep.c:450:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] We can defer handling those until we target C++11. . Adding -Wno-sign-compare suppresses thousands of instances of this warning: gdb/linux-record.c:1763:32: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] if (tmpulongest == tdep->fcntl_F_GETLK64) ^ . Adding -Wno-write-strings suppresses thousands of instances of this warning: gdb/mi/mi-cmd-var.c: In function ‘void mi_cmd_var_show_attributes(char*, char**, int)’: gdb/mi/mi-cmd-var.c:514:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] attstr = "editable"; ^ gdb/mi/mi-cmd-var.c:516:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] attstr = "noneditable"; ^ For now, it's best to hide these warnings from view until we're '-fpermissive'-clean, and can thus start building with -Werror.

2015-02-09record btrace: add configuration structMarkus Metzger1-1/+1
Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands.

2015-01-15Move code to disable ASR to nat/Sergio Durigan Junior1-1/+5
This patch moves the shared code present on gdb/linux-nat.c:linux_nat_create_inferior and gdb/gdbserver/linux-low.c:linux_create_inferior to nat/linux-personality.c. This code is responsible for disabling address space randomization based on user setting, and using <sys/personality.h> to do that. I decided to put the prototype of the maybe_disable_address_space_randomization on nat/linux-osdata.h because it seemed the best place to put it.

2015-01-14Detect 64-bit-ness in PowerPC Book III-EYao Qi1-0/+4
This patch is to teach both GDB and GDBServer to detect 64-bit inferior correctly. We find a problem that GDBServer is unable to detect on a e5500 core processor. Current GDBServer assumes that MSR is a 64-bit register, but MSR is a 32-bit register in Book III-E. This patch is to fix this problem by checking the right bit in MSR, in order to handle both Book III-S and Book III-E. In order to detect Book III-S and Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by getauxval on glibc >= 2.16. If getauxval doesn't exist, we implement the fallback by parsing /proc/self/auxv), because it should an invariant on the same machine cross different processes. In order to share code, I add nat/ppc-linux.c for both GDB and GDBserver side. gdb: 2015-01-14 Yao Qi <yao@codesourcery.com> * Makefile.in (ppc-linux.o): New rule. * config/powerpc/ppc64-linux.mh (NATDEPFILES): Add ppc-linux.o. * configure.ac: AC_CHECK_FUNCS(getauxval). * config.in: Re-generated. * configure: Re-generated. * nat/ppc-linux.h [__powerpc64__] (ppc64_64bit_inferior_p): Declare. * nat/ppc-linux.c: New file. * ppc-linux-nat.c (ppc_linux_target_wordsize) [__powerpc64__]: Call ppc64_64bit_inferior_p. gdb/gdbserver: 2015-01-14 Yao Qi <yao@codesourcery.com> * Makefile.in (SFILES): Add nat/ppc-linux.c.

When I use PPC_FEATURE_BOOKE in GDBserver, I find it is defined in GDB but not in GDBserver.

2015-01-09Don't munge yacc's #line directivesPatrick Palka1-1/+0
The #line directives within GDB's autogenerated yacc files (e.g. c-exp.c) are being incorrectly munged, causing these directives to refer to nonexistent source files, e.g. #line 36 "/home/patrick/binutils-gdb/gdb//home/patrick/binutils-gdb/gdb/c-exp.y" as opposed to #line 36 "/home/patrick/binutils-gdb/gdb/c-exp.y" The munging happens due to a sed expression added by commit 954d8cae whose intended purpose[1] was to work around the fact that ylwrap emitted #line directives without any directory information, e.g. #line 36 "c-exp.y" So the sed expression was meant to munge such directives to refer to absolute paths instead. But the behavior of ylwrap was changed some years ago[2] to emit absolute paths within #line directives. And when our local copy of ylwrap was synced by commit e30465112, the sed expression in question became unnecessary, and indeed harmful. This patch removes the now-obsolete sed expression. The emitted #line directives are now correct without it. gdb/ChangeLog: * Makefile.in (.y.c): Don't munge yacc's #line directives.

2014-12-12the "compile" commandTom Tromey1-4/+57
This final patch adds the new "compile" command and subcommands, and all the machinery needed to make it work. A shared library supplied by gcc is used for all communications with gcc. Types and most aspects of symbols are provided directly by gdb to the compiler using this library. gdb provides some information about the user's code using plain text. Macros are emitted this way, and DWARF location expressions (and bounds for VLA) are compiled to C code. This hybrid approach was taken because, on the one hand, it is better to provide global declarations and such on demand; but on the other hand, for local variables, translating DWARF location expressions to C was much simpler than exporting a full compiler API to gdb -- the same result, only easier to implement, understand, and debug. In the ordinary mode, the user's expression is wrapped in a dummy function. After compilation, gdb inserts the resulting object code into the inferior, then calls this function. Access to local variables is provided by noting which registers are used by location expressions, and passing a structure of register values into the function. Writes to registers are supported by copying out these values after the function returns. This approach was taken so that we could eventually implement other more interesting features based on this same infrastructure; for example, we're planning to investigate inferior-side breakpoint conditions. gdb/ChangeLog 2014-12-12 Phil Muldoon <pmuldoon@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Tom Tromey <tromey@redhat.com> * NEWS: Update. * symtab.h (struct symbol_computed_ops) <generate_c_location>: New field. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.h (struct language_defn) <la_get_compile_instance, la_compute_program>: New fields. * language.c (unknown_language_defn, auto_language_defn) (local_language_defn): Update. * jv-lang.c (java_language_defn): Update. * go-lang.c (go_language_defn): Update. * f-lang.c (f_language_defn): Update. * dwarf2loc.h (dwarf2_compile_property_to_c): Declare. * dwarf2loc.c (dwarf2_compile_property_to_c) (locexpr_generate_c_location, loclist_generate_c_location): New functions.
