2014-01-28New Ada maintenance command to ignore descriptive types (DWARF).Joel Brobecker5-0/+108
Currently, Ada debugging requires the use of certain GNAT-specific encodings, which are generated by the compiler. These encodings were created a long time ago to work around the fairly limited capabilities of the stabs debugging format. With DWARF, the vast majority of the encodings could be abandoned in favor of a pure DWARF approach. In order to make it easier to evaluate the quality of the DWARF debugging information generated by the compiler, and how the debugger handles it, we are introducing a small Ada-specific maintenance setting which changes the debugger's behavior to ignore descriptive types. Descriptive types are artificial types generated by the compiler purely to give the debugger hints as to how to properly decode certain properties of a type. For instance, for array types, it generates a parallel type whose name is the name of the array suffixed with ___XA, whose contents tells us what the array's index type is, and possibly its bounds. See GCC's gcc/ada/exp_dbug.ads for the full description of all encodings. This is only a first step, as this setting does not deactivate all encodings; More settings dedicated to each type of encoding will likely be implemented in the future, as we make progress. gdb/ChangeLog: * ada-lang.c (maint_set_ada_cmdlist, maint_show_ada_cmdlist): New static globals. (maint_set_ada_cmd, maint_show_ada_cmd): New functions. (ada_ignore_descriptive_types_p): New static global.

(_initialize_ada_language): Register new commands "maintenance set ada", "maintenance show ada", "maintenance set ada ignore-descriptive-types" and "maintenance show ada ignore-descriptive-types". * NEWS: Add entry for new "maint ada set/show ignore-descriptive-types" commands. gdb/doc/ChangeLog: * gdb.texinfo (Ada Glitches): Document the new "maint ada set/show ignore-descriptive-types". commands.

2014-01-27btrace: initiate teardown when closing record btrace targetMarkus Metzger2-1/+11
The to_teardown_btrace target method is used to free btrace resources during shutdown when target record has already been unpushed and we can't reliably talk to a remote target to disable branch tracing. Tracing resources are freed for each thread when the thread is removed; both on the GDB side and on the gdbserver side. In the remote case, the remote target that provides to_teardown_btrace to free the GDB side resources has already been unpushed when threads are destroyed. This results in a complaint "You can't do this ..." and in a few bytes of memory leaked for each thread. Initiate btrace teardown in record_btrace_close, so the remote target is still in place. 2014-01-27 Markus Metzger <markus.t.metzger@intel.com> * record-btrace.c (record_btrace_close): Call btrace_teardown for all threads.
2014-01-27ada-lang.c: Really include "ui-out.h".Joel Brobecker2-2/+5
Currently, ada-lang.c pretends to include "ui-out.h" as follow: #ifdef UI_OUT #include "ui-out.h" #endif However, UI_OUT is never defined as far as I can tell. This is confirmed by rebuilding with a #error pragma inside the #ifdef UI_OUT block, which never triggers. Since this unit makes references to declarations from ui-out.h, this patch simply removes the #ifdef/#endif condition. This has not been an error so far because "ui-out.h" indirectly gets included, via one of the other .h files being included. gdb/ChangeLog: * ada-lang.c: Remove "#ifdef UI_OUT" condition for including "ui-out.h".
2014-01-27Try printing array range using the name of its index typeJoel Brobecker7-9/+172
type Char_Table is array (Character range Character'First .. Character'Last) of Natural; Trying to print the type description of this type currently yields: (gdb) ptype char_table type = array ('["00"]' ..

2014-01-27[Ada] Array bound incorrectly printed for array indexed by enum subrangeJoel Brobecker2-1/+6
Consider the following declarations: type Range_Type is (One, Two, Three); type Array_Type is array (Range_Type range One .. Two) of Integer; A : Array_Type := (1, 2); Trying to print A can yield: (gdb) print a $1 = (one => 1, 2) The bound of the first element should not have been printed, since "one" is the first enumerate of type Range_Type. Similarly, with the following declarations: type Array2_Type is array (Range_Type range Two .. Three) of Integer; A2 : Array2_Type := (2, 3); GDB is failing to print the bound of the first element of "A2": (gdb) print a2 $2 = (2, 3) This is because the index type for both types Array_Type and Array2_Type are subranges (by DWARF definition for arrays), of an anonymous subrange type. When deciding whether to print the bound of the first element, we handle subranges, but only up to one level. This patch enhanced the code to handle any number of subrange levels. gdb/ChangeLog: * ada-valprint.c (print_optional_low_bound): Get index_type's target type for as long as it is a TYPE_CODE_RANGE. No testcase with this patch, but this will be tested via the testcase of another patch, which uses the DWARF assembler to generate debugging info for an array indexed by an enum.
2014-01-27Remove assert in procfs.c::procfs_make_note_section (x86-solaris)Joel Brobecker2-3/+5
On x86-solaris, the gcore command sometimes triggers the following internal error: (gdb) gcore /[...]/procfs.c:5523: internal-error: procfs_make_note_section: Assertion `thread_args.note_data != note_data' failed. The problem is extremely elusive, for reasons that will become clearer as I explain what is going on. The program used to produce this issue was really simple: | void break_me (void) { } | | int | main (void) | { | break_me (); | return 0; | } The procfs_make_note_section builds a buffer incrementally with the contents of the core's notes section. The interesting bits are: char *note_data = NULL; [...] note_data = (char *) elfcore_write_prpsinfo (obfd, note_data, note_size, fname, psargs); This is the first call to bfd's elfcore which initializes note_data. After that, we have a few more calls, which keep updating notes_data and note_size, but our interest lies in the following part of the function: thread_args.note_data = note_data; [...] proc_iterate_over_threads (pi, procfs_corefile_thread_callback, &thread_args); /* There should be always at least one thread. */ gdb_assert (thread_args.note_data != note_data); The comment implies that the assert is to verify that our loop iterated over at least one thread. The check is relying on the fact that the notes_data returned by the elfcore module changes at each iteration, via (in procfs_corefile_thread_callback): args->note_data = procfs_do_thread_registers (args->obfd, ptid, args->note_data, args->note_size, args->stop_signal); (which calls elfcore_write_lwpstatus). But, while it happens most of the time, thanks to a call to realloc in elfcore_write_note (the function that actually appends the data at the end of the notes buffer),... buf = (char *) realloc (buf, *bufsiz + newspace); ... this is by no means guarantied. In fact, under the right circumstances, the buffer was grown twice without changing addresses. Unfortunately, the circumstances are very sensitive, thus making this bug very elusive. This patch fixes the problem by simply removing the assert. This means we're losing the assertion that there is at least one thread, but I think that's OK. If we still want to keep the assertion, we have the option of either checking the buffer size, or else adding a boolean flag in the context structure that we'd set to true as soon as we have a thread. gdb/ChangeLog: * procfs.c (procfs_make_note_section): Remove assertion and associated comment.

2014-01-24Change len's type to ULONGEST: remote_write_bytes_auxYao Qi2-3/+9
Hi, This patch changes the type of 'len' from ssize_t to ULONGEST. At the beginning Siddhesh Poyarekar proposed this patch [PATCH] Memory reads and writes should have size_t length https://sourceware.org/ml/gdb-patches/2012-05/msg01073.html to change type of 'len' to size_t. However, after Jan's review, we decide to change it to ssize_t, because callers of these functions may pass signed type to them. AFAICS, the target layer is a boundary. In one side, we pass size_t or ssize_t to target related APIs, and in the other side, the implementation side, we used LONGEST (ULONGEST in latest code) because of to_xfer_partial. Since remote_write_bytes_aux and remote_write_bytes belong to the implementation of remote target, we should use ULONGEST for len, IMO. Regression tested on x86_64-linux. Is it OK? gdb: 2014-01-24 Yao Qi <yao@codesourcery.com> * remote.c (remote_write_bytes_aux): Change type of 'len' to ULONGEST. Don't check 'len' is negative.

2014-01-24TLS orphan section placementAlan Modra2-52/+89
Ensures TLS orphans are placed adjacent to existing TLS sections, and fixes places where the output_section_statement flags (which might not be set) were tested when bfd_section flags were available. * ldlang.c (lang_output_section_find_by_flags): Be careful to test look->bfd_section->flags if available rather than look->flags. Separate SEC_THREAD_LOCAL handling from SEC_READONLY loop, and rewrite.
2014-01-24Fixes powerpc64le ld segfaults when --emit-relocs is used.Alan Modra2-5/+11
ELFv2 needs fewer relocs to annotate plt call stubs. I correctly allocated a smaller buffer and wrote the proper relocs, but stupidly bumped the reloc count as for ELFv1. * elf64-ppc.c (ppc_build_one_stub): Correct reloc count passed to get_relocs for ELFv2.

2014-01-23Remove the display of known MCU names from the MSP430 port of GAS.Nick Clifton2-36/+23
New MSP430 MCU parts are being created by TI all the time and the list is basically always out of date. Instead any name will be accepted by the -mmcu= command line option. ISA selection is now based upon the -mcpu= command line option, just as is done for GCC. gas/ChangeLog * config/tc-msp430.c (show_mcu_list): Delete. (md_parse_option): Accept any MCU name. Accept several more variants for the -mcpu option. (md_show_usage): Do not call show_mcu_list.
2014-01-23Issue a linker error if TLS sections are not adjacentH.J. Lu2-3/+29
Bad linker script may lead to TLS sections separated by non-TLS sections in output. This patch changes linker assert to a linker error to provide better linker diagnosis. PR ld/16498 * elf.c (_bfd_elf_map_sections_to_segments): Issue a linker error if TLS sections are not adjacent.
2014-01-23avoid python exception in FrameDecorator.pyTom Tromey2-2/+17
This fixes a bug in FrameDecorator.py. FrameVars seems to assume that Frame.block can return None if there is no block. However, it actually throws an exception. I saw this bug while developing a frame filter, but unfortunately I don't know how to reproduce it. It seems to me that the SAL tests in _is_limited_frame should exclude the bad cases; and in my attempts to write a test they do. Nevertheless I think the fix is reasonably obvious and ought to go in. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16485: * python/lib/gdb/FrameDecorator.py: (FrameVars.fetch_frame_args): Handle exception from frame.block. (FrameVars.fetch_frame_locals): Likewise.
2014-01-23fix erroneous error-handling in frame filter codeTom Tromey5-3/+47
This fixes PR python/16487. The bug here is that the function-name-handling code in py_print_frame had a small logic error (really a misplaced closing brace). This error could lead to a Py_DECREF(NULL), which crashes. This patch fixes the bug in the obvious way. Built and regtested on x86-64 Fedora 18. New test case included. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16487: * python/py-framefilter.c (py_print_frame): Don't call Py_DECREF on a NULL pointer. Move "goto error" to correct place. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16487: * gdb.python/py-framefilter.exp: Add test using "Error" filter. * gdb.python/py-framefilter.py (ErrorInName, ErrorFilter): New classes.
2014-01-23fix crash in frame filtersTom Tromey5-7/+23
apply_frame_filter calls ensure_python_env before computing the gdbarch to use. This means that python_gdbarch can be NULL while in Python code, and if a frame filter depends on this somehow (easy to do), gdb will crash. The fix is to compute the gdbarch first. Built and regtested on x86-64 Fedora 18. New test case included. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16491: * python/py-framefilter.c (apply_frame_filter): Call ensure_python_env after computing gdbarch. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16491: * gdb.python/py-framefilter.py (Reverse_Function.function): Read a string from an inferior frame. * gdb.python/py-framefilter-mi.exp: Update.
