2020-05-08Speed up psymbol reading by removing a copyTom Tromey1-10/+7
I noticed that cp_canonicalize_string and friends copy a unique_xmalloc_ptr to a std::string. However, this copy isn't genuinely needed anywhere, and it serves to slow down DWARF psymbol reading. This patch removes the copy and updates the callers to adapt. This speeds up the reader from 1.906 seconds (mean of 10 runs, of gdb on a copy of itself) to 1.888 seconds (mean of 10 runs, on the same copy as the first trial). gdb/ChangeLog 2020-05-08 Tom Tromey <tom@tromey.com> * symtab.h (class demangle_result_storage) <set_malloc_ptr>: New overload. <swap_string, m_string>: Remove. * symtab.c (demangle_for_lookup, completion_list_add_symbol): Update. * stabsread.c (define_symbol, read_type): Update. * linespec.c (find_linespec_symbols): Update. * gnu-v3-abi.c (gnuv3_get_typeid): Update. * dwarf2/read.c (dwarf2_canonicalize_name): Update. * dbxread.c (read_dbx_symtab): Update. * cp-support.h (cp_canonicalize_string_full) (cp_canonicalize_string, cp_canonicalize_string_no_typedefs): Return unique_xmalloc_ptr. * cp-support.c (inspect_type): Update.

2020-04-24Remove symbol_get_demangled_nameTom Tromey1-3/+0
Now that symbol_get_demangled_name is only used by general_symbol_info methods, and because these methods already check the symbol's language to decide what to return, symbol_get_demangled_name is no longer needed.

2020-04-01Avoid copying in lookup_name_infoTom Tromey1-13/+42
lookup_name_info always copies the name that is passed in. However, normally a copy is not needed. This patch changes this class to avoid copying. This required changing the "name" method to return something else; I chose a gdb::string_view, to avoid excessive calls to strlen in the code using the lookup_name_info. However, as this class does not allow an arbitrary string_view, I've also added a c_str method that guarantees a \0-terminated result -- a pedantic difference but one that respects the string_view contract, IMO. gdb/ChangeLog 2020-04-01 Tom Tromey <tromey@adacore.com> * symtab.h (class lookup_name_info) <lookup_name_info>: Change "name" parameter to rvalue reference.

2020-03-25[gdb] Print user/includes fields for maint commandsTom de Vries1-0/+7
The type struct compunit_symtab contains two fields (disregarding field next) that express relations with other compunit_symtabs: user and includes. These fields are currently not printed with "maint info symtabs" and "maint print symbols". Fix this such that for "maint info symtabs" we print: ... { ((struct compunit_symtab *) 0x23e8450) debugformat DWARF 2 producer (null) dirname (null) blockvector ((struct blockvector *) 0x23e8590) + user ((struct compunit_symtab *) 0x2336280) + ( includes + ((struct compunit_symtab *) 0x23e85e0) + ((struct compunit_symtab *) 0x23e8960) + ) { symtab <unknown> ((struct symtab *) 0x23e85b0) fullname (null) linetable ((struct linetable *) 0x0) } } ... And for "maint print symbols" we print: ... -Symtab for file <unknown> +Symtab for file <unknown> at 0x23e85b0 Read from object file /data/gdb_versions/devel/a.out (0x233ccf0) Language: c Blockvector: block #000, object at 0x23e8530, 0 syms/buckets in 0x0..0x0 block #001, object at 0x23e84d0 under 0x23e8530, 0 syms/buckets in 0x0..0x0 +Compunit user: 0x2336300 +Compunit include: 0x23e8900 +Compunit include: 0x23dd970 ... Note: for user and includes we don't list the actual compunit_symtab address, but instead the corresponding symtab address, which allows us to find that symtab elsewhere in the output (given that we also now print the address of symtabs). gdb/ChangeLog: 2020-03-25 Tom de Vries <tdevries@suse.de> * symtab.h (is_main_symtab_of_compunit_symtab): New function. * symmisc.c (dump_symtab_1): Print user and includes fields.

2020-03-10gdb: Add support for tracking the DWARF line table is-stmt fieldAndrew Burgess1-0/+10
This commit brings support for the DWARF line table is_stmt field to GDB. The is_stmt field is used by the compiler when a single source line is split into multiple assembler instructions, especially if the assembler instructions are interleaved with instruction from other source lines. The compiler will set the is_stmt flag false from some instructions from the source lines, these instructions are not a good place to insert a breakpoint in order to stop at the source line. Instructions which are marked with the is_stmt flag true are a good place to insert a breakpoint for that source line. Currently GDB ignores all instructions for which is_stmt is false. This is fine in a lot of cases, however, there are some cases where this means the debug experience is not as good as it could be. Consider stopping at a random instruction, currently this instruction will be attributed to the last line table entry before this point for which is_stmt was true - as these are the only line table entries that GDB tracks. This can easily be incorrect in code with even a low level of optimisation. With is_stmt tracking in place, when stopping at a random instruction we now attribute the instruction back to the real source line, even when is_stmt is false for that instruction in the line table. When inserting breakpoints we still select line table entries for which is_stmt is true, so the breakpoint placing behaviour should not change. When stepping though code (at the line level, not the instruction level) we will still stop at instruction where is_stmt is true, I think this is more likely to be the desired behaviour. Instruction stepping is, of course, unchanged, stepping one instruction at a time, but we should now report more accurate line table information with each instruction step. The original motivation for this work was a patch posted by Bernd here: https://sourceware.org/ml/gdb-patches/2019-11/msg00792.html As part of that thread it was suggested that many issues would be resolved if GDB supported line table views, this isn't something I've attempted in this patch, though reading the spec, it seems like this would be a useful feature to support in GDB in the future. The spec is here: http://dwarfstd.org/ShowIssue.php?issue=170427.1 And Bernd gives a brief description of the benefits here: https://sourceware.org/ml/gdb-patches/2020-01/msg00147.html With that all said, I think that there is benefit to having proper is_stmt support regardless of whether we have views support, so I think we should consider getting this in first, and then building view support on top of this. The gdb.cp/step-and-next-inline.exp test is based off a test proposed by Bernd Edlinger in this message: https://sourceware.org/ml/gdb-patches/2019-12/msg00842.html gdb/ChangeLog: * buildsym-legacy.c (record_line): Pass extra parameter to record_line. * buildsym.c (buildsym_compunit::record_line): Take an extra parameter, reduce duplication in the line table, and record the is_stmt flag in the line table. * buildsym.h (buildsym_compunit::record_line): Add extra parameter. * disasm.c (do_mixed_source_and_assembly_deprecated): Ignore non-statement lines. * dwarf2/read.c (dwarf_record_line_1): Add extra parameter, pass this to the symtab builder.

2020-01-08Change section_offsets to a std::vectorTom Tromey1-22/+3
This changes section_offsets to be specialization of a std::vector and updates all the users. It also removes the ANOFFSET and SIZEOF_N_SECTION_OFFSETS macros. Most of this is just a generic sort of cleanup, that reduces the number of lines of code. However, a couple spots were doing weird things. objfile_relocate did: - std::vector<struct section_offsets> - new_debug_offsets (SIZEOF_N_SECTION_OFFSETS (debug_objfile->num_sections)); ... which seems to greatly over-estimate the number of elements needed. This appeared in set_objfile_default_section_offset: - std::vector<struct section_offsets> offsets (objf->num_sections, - { { offset } }); ... which makes sense due to type safety, but is also actively confusing given that section_offsets was previously also a kind of vector type.

Also renames the member variable to m_language to make code easier to read when more functions become member functions.

2019-12-04gdb/mi: Add -max-results parameter to some -symbol-info-* commandsAndrew Burgess1-7/+26
Adds a new parameter -max-results to -symbol-info-functions, -symbol-info-variables, -symbol-info-types, and -symbol-info-modules. This parameter limits the number of results returned. This change still leaves -symbol-info-module-functions and -symbol-info-module-variables always returning all results, fixing these commands is slightly harder. There's currently no mechanism for the user of these commands to know if the result list has been truncated if you get back the maximum number of results, so if there are exactly 10 functions and you call '-symbol-info-functions --max-results 10' the reply would appear no different than if you had 20 functions and called with a max of 10. Right now, if you get back the maximum then you should assume that there might be more results available. One other thing to note is that the global_symbol_searcher::search by default returns SIZE_MAX results, there's no longer a mechanism to return an unlimited number of results, though hopefully this will not be a huge issue. gdb/ChangeLog: * mi/mi-symbol-cmds.c (mi_symbol_info): Take extra parameter, and add it into the search spec.

2019-11-27gdb: Split print_symbol_info into two partsAndrew Burgess1-0/+8
Split the function print_symbol_info into two parts, the new worker core returns a string, which print_symbol_info then prints. This will be useful in a later commit when some new MI commands will be added which will use the worker core to fill some MI output fields. There should be no user visible changes after this commit. gdb/ChangeLog: * symtab.c (symbol_to_info_string): New function, most content moved from print_symbol_info, but updated to return a std::string. (print_symbol_info): Update to use symbol_to_info_string and print returned string. * symtab.h (symbol_to_info_string): Declare new function. Change-Id: I6454ce43cacb61d32fbadb9e3655e70823085777
2019-11-27gdb: Introduce global_symbol_searcherAndrew Burgess1-11/+65
Introduce a new class to wrap up the parameters needed for the function search_symbols, which has now become a member function of this new class. The motivation is that search_symbols already takes a lot of parameters, and a future commit is going to add even more. This commit hopefully makes collecting the state required for a search easier. As part of this conversion the list of filenames in which to search has been converted to a std::vector. There should be no user visible changes after this commit. gdb/ChangeLog: * python/python.c (gdbpy_rbreak): Convert to using global_symbol_searcher. * symtab.c (file_matches): Convert return type to bool, change file list to std::vector, update header comment. (search_symbols): Rename to... (global_symbol_searcher::search): ...this and update now its a member function of global_symbol_searcher. Take account of the changes to file_matches. (symtab_symbol_info): Convert to using global_symbol_searcher. (rbreak_command): Likewise. (search_module_symbols): Likewise. * symtab.h (enum symbol_search): Update comment. (search_symbols): Remove declaration. (class global_symbol_searcher): New class. Change-Id: I488ab292a892d9e9e84775c632c5f198b6ad3710
2019-11-26Demangle minsyms in parallelTom Tromey1-0/+10
This patch introduces a simple parallel for_each and changes the minimal symbol reader to use it when computing the demangled name for a minimal symbol. This yields a speedup when reading minimal symbols. 2019-11-26 Christian Biesinger <cbiesinger@google.com> Tom Tromey <tom@tromey.com> * minsyms.c (minimal_symbol_reader::install): Use parallel_for_each. * gdbsupport/parallel-for.h: New file. * Makefile.in (HFILES_NO_SRCDIR): Add gdbsupport/parallel-for.h.

2019-11-26Defer minimal symbol name-settingTom Tromey1-0/+4
Currently the demangled name of a minimal symbol is set when creating the symbol. However, there is no intrinsic need to do this. This patch instead arranges for the demangling to be done just before the minsym hash tables are filled. This will be useful in a later patch. gdb/ChangeLog 2019-11-26 Tom Tromey <tom@tromey.com> * symtab.h (struct minimal_symbol) <name_set>: New member. * minsyms.c (minimal_symbol_reader::record_full): Copy name.

commit 3573abe1d added static asserts to ensure that symbol sizes don't vary.

2019-10-31gdb: Add new commands to list module variables and functionsAndrew Burgess1-0/+16
This patch adds two new commands "info module functions" and "info module variables". These commands list all of the functions and variables grouped by module and then by file. For example: (gdb) info module functions All functions in all modules: Module "mod1": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 35: void mod1::__copy_mod1_M1t1(Type m1t1, Type m1t1); 25: void mod1::sub_m1_a(integer(kind=4)); 31: integer(kind=4) mod1::sub_m1_b(void); Module "mod2": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 41: void mod2::sub_m2_a(integer(kind=4), logical(kind=4)); 49: logical(kind=4) mod2::sub_m2_b(real(kind=4)); The new commands take set of flags that allow the output to be filtered, the user can filter by variable/function name, type, or containing module. As GDB doesn't currently track the relationship between a module and the variables or functions within it in the symbol table, so I filter based on the module prefix in order to find the functions or variables in each module. What this makes clear is that a user could get this same information using "info variables" and simply provide the prefix themselves, for example: (gdb) info module functions -m mod1 _a All functions matching regular expression "_a", in all modules matching regular expression "mod1": Module "mod1": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 25: void mod1::sub_m1_a(integer(kind=4)); Is similar to: (gdb) info functions mod1::.*_a.* All functions matching regular expression "mod1::.*_a": File /some/path/gdb/testsuite/gdb.fortran/info-types.f90: 25: void mod1::sub_m1_a(integer(kind=4)); The benefits I see for a separate command are that the user doesn't have to think (or know) about the module prefix format, nor worry about building a proper regexp. The user can also easily scan across modules without having to build complex regexps. The new function search_module_symbols is extern in this patch despite only being used within symtab.c, this is because a later patch in this series will also be using this function from outside symtab.c. This patch is a new implementation of an idea originally worked on by Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM. gdb/ChangeLog: * symtab.c (info_module_cmdlist): New variable.

Add a new command 'info modules' that lists all of the modules GDB knows about from the debug information. A module is a debugging entity in the DWARF defined with DW_TAG_module, currently Fortran is known to use this tag for its modules. I'm not aware of any other language that currently makes use of DW_TAG_module. The output style is similar to the 'info type' output: (gdb) info modules All defined modules: File info-types.f90: 16: mod1 24: mod2 (gdb) Where the user is told the file the module is defined in and, on the left hand side, the line number at which the module is defined along with the name of the module. This patch is a new implementation of an idea originally worked on by Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM. gdb/ChangeLog: * dwarf2read.c (dw2_symtab_iter_next): Handle MODULE_DOMAIN.

2019-10-29Change some arguments to gdb::string_view instead of name+lenChristian Biesinger1-3/+4
Just some code cleanup. This change has a few benefits: - Shorter argument list in the functions - If the caller needs to calculate the string, they no longer need to explicitly call strlen - It is easy to pass std::string to this (done in one place currently) This also updates a couple of places that were passing 0/1 to a bool parameter. gdb/ChangeLog: 2019-10-29 Christian Biesinger <cbiesinger@google.com> * coffread.c (record_minimal_symbol): Update.

2019-10-29Only make a nullterminated string if we need toChristian Biesinger1-1/+2
As of 7bb43059820c5febb4509b15202a93efde442bc6, we no longer need a nullterminated linkage_name to look up the entry in the hash table. So this patch makes it so we only make the copy if the entry was not found. By auditing all callers of symbol_set_names, I found out that all cases where the string may not be nullterminated already pass true for COPY_NAME. So here, I am documenting that as a requirement and am removing the code that relies on undefined behavior in symbol_set_names (it accessed the string past the provided length to check for nulltermination). Note that the Ada case at the beginning of symbol_set_names was already relying on this. gdb/ChangeLog: 2019-10-29 Christian Biesinger <cbiesinger@google.com> * symtab.h (symbol_set_names): Document that copy_name must be set to true for non-nullterminated strings. * symtab.c (symbol_set_names): Only make a nullterminated copy of linkage_name if the entry was not found and we need to demangle.

2019-10-02Handle copy relocationsTom Tromey1-3/+39
In ELF, if a data symbol is defined in a shared library and used by the main program, it will be subject to a "copy relocation". In this scenario, the main program has a copy of the symbol in question, and a relocation that tells ld.so to copy the data from the shared library. Then the symbol in the main program is used to satisfy all references. This patch changes gdb to handle this scenario. Data symbols coming from ELF shared libraries get a special flag that indicates that the symbol's address may be subject to copy relocation. I looked briefly into handling copy relocations by looking at the actual relocations in the main program, but this seemed difficult to do with BFD. Note that no caching is done here. Perhaps this could be changed if need be; I wanted to avoid possible problems with either objfile lifetimes and changes, or conflicts with the long-term (vapor-ware) objfile splitting project. gdb/ChangeLog 2019-10-02 Tom Tromey <tromey@adacore.com> * symmisc.c (dump_msymbols): Don't use MSYMBOL_VALUE_ADDRESS. * ada-lang.c (lesseq_defined_than): Handle LOC_STATIC. * dwarf2read.c (dwarf2_per_objfile): Add can_copy parameter.

This commit adds a '-n' flag to all of the commands listed above that excludes the non-debug symbols from the results, leaving just the debug symbol based results. gdb/ChangeLog: * cli/cli-utils.c (info_print_options_defs): Delete.

2019-08-06Add file offsets to the source cacheTom Tromey1-10/+0
Currently, gdb stores the number of lines and an array of file offsets for the start of each line in struct symtab. This patch moves this information to the source cache. This has two benefits. First, it allows gdb to read a source file less frequently. Currently, a source file may be read multiple times: once when computing the file offsets, once when highlighting, and then pieces may be read again while printing source lines. With this change, the file is read once for its source text and file offsets; and then perhaps read again if it is evicted from the cache. Second, if multiple symtabs cover the same source file, then this will share the file offsets between them. I'm not sure whether this happens in practice. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * annotate.c (annotate_source_line): Use g_source_cache. * source-cache.c (source_cache::get_plain_source_lines): Change parameters.

2019-07-09Rename common to gdbsupportTom Tromey1-5/+5
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-03-15Change minimal_symbol inheritanceTom Tromey1-31/+18
This changes struct minimal_symbol to inherit from general_symbol_info and updates various macros to cope. Because MSYMBOL_SET_LANGUAGE and MSYMBOL_SET_NAMES were only used from a single spot, this patch removes them in favor of simply inlining their definitions. I consider this to be somewhat cleaner, not least because the "phony polymorphism" provided by such macros is not useful in practice. gdb/ChangeLog 2019-03-15 Tom Tromey <tom@tromey.com> * symtab.h (struct minimal_symbol): Derive from general_symbol_info.

2019-01-10Change symbol_set_names to take an objfile_per_bfd_storageTom Tromey1-3/+5
This changes symbol_set_names to take an objfile_per_bfd_storage argument, and updates the users. It also changes PSYMBOL_SET_NAMES to take this argument directly; I feel this clarifies the storage location of objects created in psymtab.c. gdb/ChangeLog 2019-01-10 Tom Tromey <tom@tromey.com> * symtab.h (SYMBOL_SET_NAMES): Update. (symbol_set_names): Update. (MSYMBOL_SET_NAMES): Update. * symtab.c (symbol_set_names): Change argument to be an objfile_per_bfd_storage. * psymtab.c (add_psymbol_to_bcache): Update. * psympriv.h (PSYMBOL_SET_NAMES): Take per_bfd argument.
2019-01-09Remove ALL_COMPUNIT_FILETABSTom Tromey1-3/+10
This removes ALL_COMPUNIT_FILETABS, replacing its uses with ranged for loops. Because this is still used in the ALL_OBJFILE_FILETABS macro, in some places a declaration had to be removed or renamed to avoid shadowing. gdb/ChangeLog 2019-01-09 Tom Tromey <tom@tromey.com> * symtab.h (ALL_COMPUNIT_FILETABS): Remove. (compunit_filetabs): New. * symtab.c (iterate_over_some_symtabs, find_pc_sect_line): Use compunit_filetabs. (info_sources_command, make_source_files_completion_list): Remove declaration. * symmisc.c (print_objfile_statistics, dump_objfile) (maintenance_print_symbols): Remove declaration. (maintenance_info_symtabs): Use compunit_filetabs. (maintenance_info_line_tables): Likewise. * source.c (select_source_symtab): Change local variable name. (forget_cached_source_info_for_objfile): Remove declaration. * objfiles.h (ALL_OBJFILE_FILETABS): Use compunit_filetabs. * objfiles.c (objfile_relocate1): Remove declaration. * mi/mi-cmd-file.c (mi_cmd_file_list_exec_source_files): Remove declaration. * maint.c (count_symtabs_and_blocks): Use compunit_filetabs. * coffread.c (coff_symtab_read): Remove declaration. * buildsym.c (buildsym_compunit::end_symtab_with_blockvector): Use compunit_filetabs.
