Alan Modra	5446cbdf82	ppc476 icache bug workaround This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page. The patch also fixes a number of bugs in the existing support for long branch trampolines. bfd/ * elf32-ppc.c (struct ppc_elf_link_hash_table): Add params. Delete emit_stub_syms, no_tls_get_addr_opt.

Joel Brobecker	c6044dd124	New Ada maintenance command to ignore descriptive types (DWARF). 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.

Markus Metzger	568e808b7d	btrace: initiate teardown when closing record btrace target 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.	13 years ago
Joel Brobecker	467d141bf5	ada-lang.c: Really include "ui-out.h". 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".	13 years ago

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.	13 years ago
Joel Brobecker	25790f6fc1	Remove assert in procfs.c::procfs_make_note_section (x86-solaris) 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.	13 years ago

Yao Qi	6b6aa82881	Change len's type to ULONGEST: remote_read_bytes and get_core_siginfo Functions remote_read_bytes and get_core_siginfo are the callees of target to_xfer_partial interface, so argument 'len' should be changed to type ULONGEST. gdb: 2014-01-24 Yao Qi <yao@codesourcery.com> * remote.c (remote_read_bytes): Change type of len to ULONGEST. * corelow.c (get_core_siginfo): Likewise.	13 years ago
Yao Qi	5d6df42390	Change len's type to ULONGEST: remote_write_bytes_aux 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. (remote_write_bytes): Change type of 'len' to ULONGEST.	13 years ago
