2017-09-04gdb.base/commands.exp: Test loop_break and loop_continue in nested loopsSimon Marchi2-23/+47
This patch improves the loop_break and loop_continue tests to verify that they work as expected when multiple loops are nested (they affect the inner loop). gdb/testsuite/ChangeLog: * gdb.base/commands.exp (loop_break_test, loop_continue_test): Test with nested loops.
2017-09-04Introduce gdb_disassembly_flagsPedro Alves11-56/+114
For some reason I ended up staring at some of the "int flags" in btrace-related code, and I got confused because I had no clue what the flags where supposed to indicate. Fix that by using enum_flags, so that: #1 - it's clear from the type what the flags are about, and #2 - the compiler can catch mismatching mistakes gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (print_disassembly, disassemble_current_function) (disassemble_command): Use gdb_disassembly_flags instead of bare int. * disasm.c (gdb_pretty_print_disassembler::pretty_print_insn) (dump_insns, do_mixed_source_and_assembly_deprecated) (do_mixed_source_and_assembly, do_assembly_only, gdb_disassembly): Use gdb_disassembly_flags instead of bare int. * disasm.h (DISASSEMBLY_SOURCE_DEPRECATED, DISASSEMBLY_RAW_INSN) (DISASSEMBLY_OMIT_FNAME, DISASSEMBLY_FILENAME) (DISASSEMBLY_OMIT_PC, DISASSEMBLY_SOURCE) (DISASSEMBLY_SPECULATIVE): No longer macros.

2017-09-04Add tests for loop_break and loop_continue commandsSimon Marchi2-0/+48
I grepped the testsuite for loop_break and loop_continue and didn't find anything, so I wrote some simple tests for those. gdb/testsuite/ChangeLog: * gdb.base/commands.exp: Call the new procedures. (loop_break_test, loop_continue_test): New procedures.
2017-09-04Error out immediatly when using if command without args in command listSimon Marchi4-1/+28
When using "if" (or while) without args directly on gdb's command line, you get this: (gdb) if if/while commands require arguments When doing the same when entering a command list, you only get an error when the command is executed, when parse_exp_in_context_1 fails to evaluate the expression. (gdb) define foo Type commands for definition of "foo". End with a line saying just "end". >if >end >end (gdb) foo Argument required (expression to compute). I think it would make more sense to error out when inputting the command list directly: (gdb) define foo Type commands for definition of "foo". End with a line saying just "end". >if if/while commands require arguments. The only required change is to check whether args is an empty string in build_command_line. gdb/ChangeLog: * cli/cli-script.c (build_command_line): For if/while commands, check whether args is empty. gdb/testsuite/ChangeLog: * gdb.base/commands.exp: Call new procedure. (define_if_without_arg_test): New procedure.
2017-09-04Move command lines types/declarations to cli-script.hSimon Marchi6-75/+100
I think it would make more sense if the types and function declarations related to command lines were in cli-script.h rather than defs.h, since the related function definitions are in cli-script.c. I had to add a few includes here and there. I also had to rename the "lines" parameter of command_lines_deleter::operator(), because ncurses has a "#define lines ..." that was interfering when cli-script.h is included by some TUI source files that also include ncurses header files. gdb/ChangeLog: * cli/cli-script.h (enum misc_command_type): Move from defs.h. (enum command_control_type): Likewise. (struct command_line): Likewise. (free_command_lines): Likewise. (struct command_lines_deleter): Likewise. (command_line_up): Likewise.

2017-09-04gdbserver Makefile: don't delete intermediary filesSimon Marchi2-0/+7
If you "make" from scratch in gdbserver/, you'll notice that make deletes the files it considers as intermediary at the end: $ make clean && make ... rm i386-mmx-linux-generated.c x32-avx-avx512-linux-generated.c ... Then, if you type make again, make will rebuild these files and rebuild gdbserver. To avoid this, we can add the .SECONDARY special target. If it has no pre-requisites, all intermediary files will be kept. gdb/gdbserver/ChangeLog: * Makefile.in (.SECONDARY): Define target.
2017-09-04Kill init_salPedro Alves26-206/+176
Instead, make symtab_and_line initialize its members itself. Many symtab_and_line declarations are moved to where the object is initialized at the same time both for clarity and to avoid double initialization. A few functions, like e.g., find_frame_sal are adjusted to return the sal using normal function return instead of an output parameter likewise to avoid having to default-construct a sal and then immediately have the object overwritten. gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * ada-lang.c (is_known_support_routine): Move sal declaration to where it is initialized. * breakpoint.c (create_internal_breakpoint, init_catchpoint) (parse_breakpoint_sals, decode_static_tracepoint_spec) (clear_command, update_static_tracepoint): Remove init_sal references.

2017-09-04struct symtabs_and_lines -> std::vector<symtab_and_line>Pedro Alves19-630/+517
This replaces "struct symtabs_and_lines" with std::vector<symtab_and_line> in most cases. This removes a number of cleanups. In some cases, the sals objects do not own the sals they point at. Instead they point at some sal that lives on the stack. Typically something like this: struct symtab_and_line sal; struct symtabs_and_lines sals; // fill in sal sals.nelts = 1; sals.sals = &sal; // use sals Instead of switching those cases to std::vector too, such usages are replaced by gdb::array_view<symtab_and_line> instead. This avoids introducing heap allocations. gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * ax-gdb.c (agent_command_1): Use range-for. * break-catch-throw.c (re_set_exception_catchpoint): Update. * breakpoint.c: Include "common/array-view.h".

2017-09-04Introduce gdb::array_viewPedro Alves4-0/+683
An array_view is an abstraction that provides a non-owning view over a sequence of contiguous objects. A way to put it is that array_view is to std::vector (and std::array and built-in arrays with rank==1) like std::string_view is to std::string. The main intent of array_view is to use it as function input parameter type, making it possible to pass in any sequence of contiguous objects, irrespective of whether the objects live on the stack or heap and what actual container owns them. Implicit construction from the element type is supported too, making it easy to call functions that expect an array of elements when you only have one element (usually on the stack). For example: struct A { .... }; void function (gdb::array_view<A> as); std::vector<A> std_vec = ...; std::array<A, N> std_array = ...; A array[] = {...}; A elem; function (std_vec); function (std_array); function (array); function (elem); Views can be either mutable or const. A const view is simply created by specifying a const T as array_view template parameter, in which case operator[] of non-const array_view objects ends up returning const references. (Making the array_view itself const is analogous to making a pointer itself be const. I.e., disables re-seating the view/pointer.) Normally functions will pass around array_views by value. Uses of gdb::array_view (other than the ones in the unit tests) will be added in a follow up patch. gdb/ChangeLog 2017-09-04 Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/array-view-selftests.c.

2017-09-04Clarify "list" output when specified lines are ambiguousPedro Alves7-8/+203
Currently, with "list LINESPEC1,LINESPEC2", if one of the linespecs is ambiguous, i.e., if it expands to multiple locations, you get this seemingly odd output: (gdb) list foo,bar file: "file0.c", line number: 26 file: "file1.c", line number: 29 Since "foo" above expands to multiple locations, the specified range is indeterminate, and GDB is trying to be helpful by showing you what was ambiguous. It looks confusing to me, though. I think it'd be much more user friendly if GDB actually told you that, like this: (gdb) list foo,bar Specified first line 'foo' is ambiguous: file: "file0.c", line number: 26 file: "file1.c", line number: 29 (gdb) list bar,foo Specified last line 'foo' is ambiguous: file: "file0.c", line number: 26 file: "file1.c", line number: 29 Note, I'm using "first" and "last" in the output because that's what the manual uses: ~~~ list first,last Print lines from first to last. [...] ~~~ Tested on x86-64 GNU/Linux. gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (edit_command): Pass message to ambiguous_line_spec. (list_command): Pass message to ambiguous_line_spec. Say "first"/"last" instead of "start" and "end" to be consistent with the manual. (ambiguous_line_spec): Add 'format' and vararg parameters. Use them to print formatted message. gdb/testsuite/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * gdb.base/list-ambiguous.exp: New file. * gdb.base/list-ambiguous0.c: New file. * gdb.base/list-ambiguous1.c: New file. * gdb.base/list.exp (test_list_range): Adjust expected output.

2017-09-04Let i386_target_description return tdesc_i386_mmxYao Qi4-4/+15
This patch remove the usage of tdesc_i386_mmx in i386-go32-tdep.c, and use i386_target_description to get it instead. gdb: 2017-09-04 Yao Qi <yao.qi@linaro.org> * i386-go32-tdep.c: Include x86-xstate.h.

i386fbsd_core_read_xcr0 reads the value of xcr0 from the corefile. If it fails, returns 0. This makes its caller {i386,amd64}_target_description has to handle this special value.

2017-08-31Implement the ability to set/unset environment variables to GDBserver when ↵Sergio Durigan Junior15-65/+984
starting the inferior This patch implements the ability to set/unset environment variables on the remote target, mimicking what GDB already offers to the user. There are two features present here: user-set and user-unset environment variables. User-set environment variables are only the variables that are explicitly set by the user, using the 'set environment' command. This means that variables that were already present in the environment when starting GDB/GDBserver are not transmitted/considered by this feature. User-unset environment variables are variables that are explicitly unset by the user, using the 'unset environment' command. The idea behind this patch is to store user-set and user-unset environment variables in two separate sets, both part of gdb_environ. Then, when extended_remote_create_inferior is preparing to start the inferior, it will iterate over the two sets and set/unset variables accordingly. Three new packets are introduced: - QEnvironmentHexEncoded, which is used to set environment variables, and contains an hex-encoded string in the format "VAR=VALUE" (VALUE can be empty if the user set a variable with a null value, by doing 'set environment VAR='). - QEnvironmentUnset, which is used to unset environment variables, and contains an hex-encoded string in the format "VAR". - QEnvironmentReset, which is always the first packet to be transmitted, and is used to reset the environment, i.e., discard any changes made by the user on previous runs. The QEnvironmentHexEncoded packet is inspired on LLDB's extensions to the RSP. Details about it can be seen here: <https://raw.githubusercontent.com/llvm-mirror/lldb/master/docs/lldb-gdb-remote.txt> I decided not to implement the QEnvironment packet because it is considered deprecated by LLDB. This packet, on LLDB, serves the same purpose of QEnvironmentHexEncoded, but sends the information using a plain text, non-hex-encoded string. The other two packets are new. This patch also includes updates to the documentation, testsuite, and unit tests, without introducing regressions. gdb/ChangeLog: 2017-08-31 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS (Changes since GDB 8.0): Add entry mentioning new support for setting/unsetting environment variables on the remote target.

2017-08-31Unbreak gdb build on 32-bit host with ADI supportWeimin Pan2-11/+33
The problem of failing to build with arm-linux-gnueabihf-g++-4.8 was that type CORE_ADDR is of "unsigned long" on a 64-bit machine so it's OK to use %lx but is of type "unsigned long long" on a 32 bit system. Fixed the problem in three places - (1) use a temp variable of type CORE_ADDR as argument 3 when calling target_auxv_search() then assign its value to "blksize" and "nbits" in 2 calls; (2) redo adi_normalize_address() using masks and xor operators to calculate normalized address; (3) call paddress() to print CORE_ADDR in either printf_filtered() or error().

2017-08-29Look for FIR in the last FreeBSD/mips floating-point register.John Baldwin3-14/+39
FreeBSD/mips kernels were recently changed to include the floating point implementation revision register in the floating point register set exported in process cores and via ptrace() (r318067). This change will first ship in FreeBSD 12.0 when it is eventually released. The space used to hold FIR was previously reserved in 'struct fpreg' as a zero-filled dummy for padding, so 'struct fpreg' has not changed in size. Since FIR should be non-zero on all MIPS processors supported by FreeBSD, ignore a value of 0 from 'struct fpreg' and only report non-zero values as a valid FIR register. gdb/ChangeLog: * mips-fbsd-nat.c (getfpregs_supplies): Return true for FIR. * mips-fbsd-tdep.c (mips_fbsd_supply_fpregs): Split supply of FSR out of loop and add supply of FIR.

2017-08-28define_command: Don't convert command name to lower caseSimon Marchi4-6/+40
Commit Command names: make them case sensitive 3d7b173c29900879c9a5958dd6029fd36666e57c made command name lookup case sensitive. However, define_command, used when creating a user-defined command, converts the command name to lowercase, assuming that the command name lookup works in a case insensitive way. This causes user-defined commands with capital letters in their name to only be callable with a lowercase version: (gdb) define Foo Type commands for definition of "Foo". End with a line saying just "end". >print 1 >end (gdb) Foo Undefined command: "Foo". Try "help". (gdb) foo $1 = 1 This patch removes that conversion to lowercase, so that the user can call the command with the same name they provided. gdb/ChangeLog: * cli/cli-script.c (define_command): Don't convert command name to lower case. gdb/testsuite/ChangeLog: * gdb.base/commands.exp (user_defined_command_case_sensitivity): New proc, call it from toplevel.

2017-08-23Fix PR remote/21852: Remote run without specifying a local binary crashes GDBSergio Durigan Junior5-9/+108
There is an assertion that is triggering when we start GDB and instruct it to debug a remote inferior, but don't provide a local binary, like: ./gdb -nx -q --data-directory=data-directory -ex "tar ext :1234" \ -ex "set remote exec-file /bin/ls" -ex r In this case, when calling exec_file_locate_attach to locate the inferior, GDB is incorrectly resetting the breakpoints without a thread/inferior even running, which causes an assertion to be triggered: binutils-gdb/gdb/thread.c:1609: internal-error: scoped_restore_current_thread::scoped_restore_current_thread(): Assertion `tp != NULL' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) This happens because add_current_inferior_and_thread (on remote.c) is breaking an invariant: making inferior_ptid point to a non-existing thread and then calling common code, which in this case is breakpoint_re_set.

2017-08-23gdb: SPARC ADI supportWeimin Pan10-0/+903
The M7 processor supports an Application Data Integrity (ADI) feature that detects invalid data accesses. When software allocates data, it chooses a 4-bit version number, sets the version in the upper 4 bits of the 64-bit pointer to that data, and stores the 4-bit version in every cacheline of the object. Hardware saves the latter in spare bits in the cache and memory hierarchy. On each load and store, the processor compares the upper 4 VA (virtual address) bits to the cacheline's version. If there is a mismatch, the processor generates a version mismatch trap which can be either precise or disrupting. The trap is an error condition which the kernel delivers to the process as a SIGSEGV signal. The upper 4 bits of the VA represent a version and are not part of the true address. The processor clears these bits and sign extends bit 59 to generate the true address. Note that 32-bit applications cannot use ADI. This patch adds ADI support in gdb which allows the user to examine current version tags and assign new version tags in the program. It also catches and reports precise or disrupting memory corruption traps. gdb/ChangeLog: 2017-08-07 Weimin Pan <weimin.pan@oracle.com> * sparc64-tdep.h: (adi_normalize_address): New export. * sparc-nat.h: (open_adi_tag_fd): New export. * sparc64-linux-nat.c: (open_adi_tag_fd): New function. * sparc64-linux-tdep.c: (SEGV_ACCADI, SEGV_ADIDERR, SEGV_ADIPERR) New defines.

2017-08-22Fix erroneous cleanup use in add_solib_catchpointTom Tromey2-7/+7
I happened to notice that add_solib_catchpoint allocated the new catchpoint with "new" but installed a cleanup using "xfree". This patch fixes the bug by changing the function to use std::unique_ptr instead. ChangeLog 2017-08-22 Tom Tromey <tom@tromey.com> * breakpoint.c (add_solib_catchpoint): Use std::unique_ptr.
2017-08-22Change psymtab_search_name to return a unique_xmalloc_ptrTom Tromey2-20/+17
This changes psymtab_search_name to return a unique_xmalloc_ptr and fixes up its one caller. This allows the removal of some cleanups. ChangeLog 2017-08-22 Tom Tromey <tom@tromey.com> * psymtab.c (psymtab_search_name): Return a unique_xmalloc_ptr. (lookup_partial_symbol): Update.
2017-08-22Change rewrite_source_path to return a unique_xmalloc_ptrTom Tromey4-41/+33
This changes rewrite_source_path to return a unique_xmalloc_ptr and fixes up the callers. This allows removing some cleanups. ChangeLog 2017-08-22 Tom Tromey <tom@tromey.com> * source.h (rewrite_source_path): Return a unique_xmalloc_ptr. * source.c (rewrite_source_path): Return a unique_xmalloc_ptr. (find_and_open_source, symtab_to_fullname): Update. * psymtab.c (psymtab_to_fullname): Update.
2017-08-22Change gdb_realpath to return a unique_xmalloc_ptrTom Tromey15-145/+130
This changes gdb_realpath to return a unique_xmalloc_ptr and fixes up the callers. This allows removing some cleanups. This change by itself caused xfullpath.exp to fail; and attempting to fix that ran into various problems (like .get() being optimized out); so this patch also rewrites xfullpath.exp to be a C++ selftest instead. ChangeLog 2017-08-22 Tom Tromey <tom@tromey.com> * exec.c (exec_file_attach): Update. * linux-thread-db.c (try_thread_db_load): Update. * guile/scm-safe-call.c (gdbscm_safe_source_script): Update. * utils.c (gdb_realpath): Change return type.
