2017-01-13Don't print too much if remote_debug is onYao Qi2-4/+39
If we turn "remote debug" on and GDB does some vFile operations, a lot of things will be printed in the screen, which makes "remote debug" useless. This patch changes the code that we only print 512 chars in max in debugging messages, like this, Sending packet: $qXfer:features:read:target.xml:0,fff#7d...Packet received: l<?xml version="1.0"?>\n<!-- Copyright (C) 2010-2016 Free Software Foundation, Inc.\n\n Copying and distribution of this file, with or without modification,\n are permitted in any medium without royalty provided the copyright\n notice and this notice are preserved. -->\n\n<!-- AMD64 with AVX - Includes Linux-only special "register". -->\n\n<!DOCTYPE target SYSTEM "gdb-target.dtd">\n<target>\n <architecture>i386:x86-64</architecture>\n <osabi>GNU/Linux</osabi>\n <xi:include href="64bit-core.xml"/>\n <xi:[14 bytes omitted] Sending packet: $qXfer:auxv:read::0,1000#6b...Packet received: l!\000\000\000\000\000\000\000\000d\000\000\000\000\000\000\000\003\000\000\000\000\000\000\000@\000@\000\000\000\000\000\004\000\000\000\000\000\000\0008\000\000\000\000\000\000\000\005\000\000\000\000\000\000\000\t\000\000\000\000\000\000\000\a\000\000\000\000\000\000\000\177\000\000\b\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\t\000\000\000\000\000\000\000\000\004@\000\000\000\000\000\013\000\000\000\000\000\000\003\000\000\000\000\000\000\f\000\000\000\000\000\000\003\000\000\000\000\000\000\r\000\000\000\000\000\000\003\000\000\000\000\000\000\016\000\000\000\000\000\000\003\000\000\000\000\000\000\027\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\031\000\000\000\000\000\000\177\000\000\037\000\000\000\000\000\000\000\000\017\000\000\000\000\000\000\00\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000[582 bytes omitted] gdb: 2017-01-13 Yao Qi <yao.qi@linaro.org> * remote.c (REMOTE_DEBUG_MAX_CHAR): New macro.

2017-01-13Return -1 on memory error in print_insn_m68kYao Qi2-7/+19

2017-01-13Remove magic numbers in m68k-dis.c:print_insn_argYao Qi2-41/+72
When I inspect the return values of disassmblers, I happen to see various -1/-2/-3 magic numbers are used in m68k-dis.c. This patch is to replace them with enum. -1 and -2 is "clearly documented" in print_ins_arg's comments, but -3 isn't. In fact, -3 is returned when FETCH_DATA returns false, which means memory error (because fetch_data return 0 on memory error). So I name enum PRINT_INSN_ARG_MEMORY_ERROR for -3. This patch is a refactor patch, doesn't affect any functionality. opcodes: 2017-01-13 Yao Qi <yao.qi@linaro.org> * m68k-dis.c (enum print_insn_arg_error): New.

2017-01-12Remove dead serial_interface_lookup callsSimon Marchi2-5/+5
By inspecting the serial_add_interface calls, I found that the serial interface names that we have today are: - hardwire - terminal - pipe - tcp - event The calls to serial_interface_lookup with any other names are most likely leftovers which can be removed since these serial interfaces don't exist anymore. The commits that removed the "pc" and "parallel" interfaces are respectively: cb2a4ac5dae478fcd9d6e772530c3aba0576fc7a and e386d4d2fb55042f77d0557a0849ed2464aee7b3 gdb/ChangeLog: * serial.c (serial_open): Forget about "pc" and "lpt" serial interface.

2017-01-12Return -1 on memory error in print_insn_msp430Yao Qi2-14/+99

2017-01-10Use scoped_value_mark in dwarf2_evaluate_loc_desc_fullTom Tromey3-15/+32
This changes dwarf2_evaluate_loc_desc_full to use scoped_value_mark. Note that this function previously called do_cleanup using the same cleanup multiple times. I had thought this was buggy, but re-reading make_my_cleanup2 indicates that it is not. Nevertheless it is surprising, and at least one of the calls (the one that is completely removed in this patch) seems to have been done under the assumption that it would still have some effect. 2017-01-10 Tom Tromey <tom@tromey.com> * value.h (scoped_value_mark::~scoped_value_mark): Call free_to_mark.

2017-01-10Add scoped_value_markTom Tromey5-54/+55
This adds a scoped_value_mark class, that records the value mark in the constructor and then calls value_free_to_mark in the destructor. It then updates various spots in gdb to use this class, rather than a cleanup. It would be better overall to replace "struct value *" with a shared_ptr, maybe eliminating the need for this class (watchpoints would perhaps need some new mechanism as well). However, that's difficult to do. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-value.c (valpy_dereference, valpy_referenced_value) (valpy_reference_value, valpy_const_value, valpy_get_address) (valpy_get_dynamic_type, valpy_lazy_string, valpy_do_cast) (valpy_getitem, valpy_call, valpy_binop_throw, valpy_negative) (valpy_absolute, valpy_richcompare_throw): Use scoped_value_mark. * dwarf2loc.c (dwarf2_loc_desc_get_symbol_read_needs): Use scoped_value_mark. * dwarf2-frame.c (execute_stack_op): Use scoped_value_mark. * value.h (scoped_value_mark): New class.

2017-01-10Introduce and use gdb::unlinkerTom Tromey5-74/+110
This introduces a new class, gdb::unlinker, that unlinks a file in the destructor. The user of this class has the option to preserve the file instead, by calling the "keep" method. This patch then changes the spots in gdb that use unlink in a cleanup to use this class instead. In one spot I went ahead and removed all the cleanups from the function. This fixes one latent bug -- do_bfd_delete_cleanup could refer to freed memory, by decref'ing the BFD before using its filename. 2017-01-10 Tom Tromey <tom@tromey.com> * record-full.c (record_full_save_cleanups): Remove. (record_full_save): Use gdb::unlinker. * gcore.c (do_bfd_delete_cleanup): Remove. (gcore_command): Use gdb::unlinker, unique_xmalloc_ptr. Remove cleanups. * dwarf2read.c (unlink_if_set): Remove. (write_psymtabs_to_index): Use gdb::unlinker. * common/gdb_unlinker.h: New file.
2017-01-10Use class to manage BFD reference countsTom Tromey37-547/+491
This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

2017-01-10Add gdb_ref_ptr.hTom Tromey3-126/+230
This adds a new gdb_ref_ptr.h, that implements a reference-counting smart pointer class, where the user of the class supplies a reference-counting policy object. This class will be used in the next patch, which changes most explicit BFD reference counts to use this new type. Meanwhile, this patch changes gdbpy_ref to be a specialization of this new class. This change required adding new nullptr_t overloads some operators in gdb_ref_ptr.h. I suspect this was needed because some Python header redefines NULL, but I'm not certain. 2017-01-10 Tom Tromey <tom@tromey.com> * common/gdb_ref_ptr.h: New file. * python/py-ref.h (struct gdbpy_ref_policy): New. (gdbpy_ref): Now a typedef.
2017-01-10Remove make_cleanup_htab_deleteTom Tromey9-190/+148
This removes make_cleanup_htab_delete in favor of destructors, building on an earlier patch that added the htab_up typedef. Testing revealed that more cleanup-removal work was needed in dwarf2loc.c, so this version of the patch changes code there to use unordered_set and vector, removing some more cleanups. 2017-01-10 Tom Tromey <tom@tromey.com> * utils.h (make_cleanup_htab_delete): Don't declare. * utils.c (do_htab_delete_cleanup, make_cleanup_htab_delete): Remove. * linespec.c (decode_compound_collector): Add constructor, destructor. (lookup_prefix_sym): Remove cleanup. (symtab_collector): Add constructor, destructor. (collect_symtabs_from_filename): Remove cleanup. * disasm.c (do_mixed_source_and_assembly): Use htab_up. * compile/compile-c-symbols.c (generate_c_for_variable_locations): Use htab_up. * gnu-v3-abi.c (gnuv3_print_vtable): Use htab_up. * dwarf2read.c (dw2_expand_symtabs_matching) (dw2_map_symbol_filenames, dwarf_decode_macros) (write_psymtabs_to_index): Use htab_up. * dwarf2loc.c (func_verify_no_selftailcall) (call_site_find_chain_1, func_verify_no_selftailcall) (chain_candidate, call_site_find_chain_1): Use std::unordered_set, std::vector, gdb::unique_xmalloc_ptr. (call_sitep): Remove typedef. (dwarf2_locexpr_baton_eval): Remove unused variable.
2017-01-10Remove make_cleanup_py_decref and make_cleanup_py_xdecrefTom Tromey3-45/+7
make_cleanup_py_decref and make_cleanup_py_xdecref are now unused, so this patch removes themm. Future Python changes should use gdbpy_ref instead. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python-internal.h (make_cleanup_py_decref) (make_cleanup_py_xdecref): Don't declare. * python/py-utils.c (py_decref, make_cleanup_py_decref) (py_xdecref, make_cleanup_py_xdecref): Remove.
2017-01-10Use gdbpy_ref rather than make_cleanup_py_decrefTom Tromey2-31/+33
This changes some spots in py-framefilter.c to use gdbpy_ref rather than make_cleanup_py_decref or make_cleanup_py_xdecref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-framefilter.c (py_mi_print_variables): Use gdbpy_ref. (py_print_locals, enumerate_locals, py_print_args): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in enumerate_argsTom Tromey2-35/+25
This changes enumerate_args to use gdbpy_ref, and gets rid of many gotos. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-framefilter.c (enumerate_args): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py-utils.cTom Tromey2-34/+23

2017-01-10Use gdbpy_ref in pyuw_object_attribute_to_pointerTom Tromey2-3/+7
This changes pyuw_object_attribute_to_pointer to use gdbpy_ref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-unwind.c (pyuw_object_attribute_to_pointer): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in python.cTom Tromey2-67/+59
This changes more places in python.c to use gdbpy_ref. Additionally, previously gdbpy_apply_type_printers would return EXT_LANG_RC_ERROR if a type printer returned None. However, that doesn't seem correct to me; this patch changes it to return EXT_LANG_RC_NOP in this case. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python.c (eval_python_command, gdbpy_decode_line) (gdbpy_run_events, gdbpy_start_type_printers) (gdbpy_apply_type_printers): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py-param.cTom Tromey2-10/+13
This changes py-param.c to use gdbpy_ref in a couple more spots. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-param.c (get_doc_string, compute_enum_values): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py-inferior.cTom Tromey2-17/+11
