2016-10-26PR 20569, segv in follow_execSandra Loosemore1-1/+2
The following testcases make GDB crash whenever an invalid sysroot is provided, when GDB is unable to find a valid path to the symbol file: gdb.base/catch-syscall.exp gdb.base/execl-update-breakpoints.exp gdb.base/foll-exec-mode.exp gdb.base/foll-exec.exp gdb.base/foll-vfork.exp gdb.base/pie-execl.exp gdb.multi/bkpt-multi-exec.exp gdb.python/py-finish-breakpoint.exp gdb.threads/execl.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp The immediate cause of the segv is that follow_exec is passing a NULL argument (the result of exec_file_find) to strlen. However, the problem is deeper than that: follow_exec simply isn't prepared for the case where sysroot translation fails to locate the new executable. Actually all callers of exec_file_find have bugs due to confusion between host and target pathnames. This commit attempts to fix all that. In terms of the testcases that were formerly segv'ing, GDB now prints a warning but continues execution of the new program, so that the tests now mostly FAIL instead. You could argue the FAILs are due to a legitimate problem with the test environment setting up the sysroot translation incorrectly. A new representative test is added which exercises the ne wwarning code path even with native testing. Tested on x86_64 Fedora 23, native and gdbserver. gdb/ChangeLog: 2016-10-25 Sandra Loosemore <sandra@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> Pedro Alves <palves@redhat.com> PR gdb/20569 * exceptions.c (exception_print_same): Moved here from exec.c. * exceptions.h (exception_print_same): Declare. * exec.h: Include "symfile-add-flags.h".

2016-10-26Make symfile_add_flags and objfile->flags strongly typedPedro Alves1-27/+9
This makes these flag types be "enum flag" types. The benefit is making use of C++'s stronger typing -- mixing the flags types by mistake errors at compile time. This caught one old bug in symbol_file_add_main_1 already, fixed by this patch as well: @@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags) what is frameless. */ reinit_frame_cache (); - if ((flags & SYMFILE_NO_READ) == 0) + if ((add_flags & SYMFILE_NO_READ) == 0) set_initial_language (); } Above, "flags" are objfile flags, not symfile_add_flags.

2015-02-27Fix struct, union, and enum nesting in C++Tom Tromey1-8/+10
In C, an enum or structure defined inside other structure has global scope just like it had been defined outside the struct in the first place. However, in C++, such a nested structure is given a name that is nested inside the structure. This patch moves such affected structures/enums out to global scope, so that code using them works the same in C++ as it works today in C. gdb/ChangeLog: 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> * dwarf2-frame.c (enum cfa_how_kind, struct dwarf2_frame_state_reg_info): Move out of struct dwarf2_frame_state. * dwarf2read.c (struct tu_stats): Move out of struct dwarf2_per_objfile.

2015-02-27C++ keyword cleanliness, mostly auto-generatedPedro Alves1-2/+2
This patch renames symbols that happen to have names which are reserved keywords in C++. Most of this was generated with Tromey's cxx-conversion.el script. Some places where later hand massaged a bit, to fix formatting, etc. And this was rebased several times meanwhile, along with re-running the script, so re-running the script from scratch probably does not result in the exact same output. I don't think that matters anyway. gdb/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. gdb/gdbserver/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout.

2014-11-20Split struct symtab into two: struct symtab and compunit_symtab.Doug Evans1-16/+20
Currently "symtabs" in gdb are stored as a single linked list of struct symtab that contains both symbol symtabs (the blockvectors) and file symtabs (the linetables). This has led to confusion, bugs, and performance issues. This patch is conceptually very simple: split struct symtab into two pieces: one part containing things common across the entire compilation unit, and one part containing things specific to each source file. Example. For the case of a program built out of these files: foo.c foo1.h foo2.h bar.c foo1.h bar.h Today we have a single list of struct symtabs: objfile -> foo.c -> foo1.h -> foo2.h -> bar.c -> foo1.h -> bar.h -> NULL where "->" means the "next" pointer in struct symtab. With this patch, that turns into: objfile -> foo.c(cu) -> bar.c(cu) -> NULL | | v v foo.c bar.c | | v v foo1.h foo1.h | | v v foo2.h bar.h | | v v NULL NULL where "foo.c(cu)" and "bar.c(cu)" are struct compunit_symtab objects, and the files foo.c, etc. are struct symtab objects. So now, for example, when we want to iterate over all blockvectors we can now just iterate over the compunit_symtab list. Plus a lot of the data that was either unused or replicated for each symtab in a compilation unit now lives in struct compunit_symtab. E.g., the objfile pointer, the producer string, etc. I thought of moving "language" out of struct symtab but there is logic to try to compute the language based on previously seen files, and I think that's best left as is for now. With my standard monster benchmark with -readnow (which I can't actually do, but based on my calculations), whereas today the list requires 77MB to store all the struct symtabs, it now only requires 37MB. A modest space savings given the gigabytes needed for all the debug info, etc. Still, it's nice. Plus, whereas today we create a copy of dirname for each source file symtab in a compilation unit, we now only create one for the compunit. So this patch is basically just a data structure reorg, I don't expect significant performance improvements from it. Notes: 1) A followup patch can do a similar split for struct partial_symtab. I have left that until after I get the changes I want in to better utilize .gdb_index (it may affect how we do partial syms). 2) Another followup patch *could* rename struct symtab. The term "symtab" is ambiguous and has been a source of confusion. In this patch I'm leaving it alone, calling it the "historical" name of "filetabs", which is what they are now: just the file-name + line-table. gdb/ChangeLog: Split struct symtab into two: struct symtab and compunit_symtab. * amd64-tdep.c (amd64_skip_xmm_prologue): Fetch producer from compunit. * block.c (blockvector_for_pc_sect): Change "struct symtab *" argument to "struct compunit_symtab *".

2014-03-03change probes to be program-space-independentTom Tromey1-5/+0
This changes the probes to be independent of the program space. After this, when a probe's address is needed, it is determined by applying offsets at the point of use. This introduces a bound_probe object, similar to bound minimal symbols. Objects of this type are used when it's necessary to pass a probe and its corresponding objfile. This removes the backlink from probe to objfile, which was primarily used to fetch the architecture to use. This adds a get_probe_address function which calls a probe method to compute the probe's relocated address. Similarly, it adds an objfile parameter to the semaphore methods so they can do the relocation properly as well. 2014-03-03 Tom Tromey <tromey@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use bound probes. * breakpoint.c (create_longjmp_master_breakpoint): Use get_probe_address.

2014-02-26start change to progspace independenceTom Tromey1-1/+1
This patch starts changing minimal symbols to be independent of the program space. Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS and changes all the code to use it. This is needed so we can change gdb to apply the section offset when a minsym's address is computed, as opposed to baking the offsets into the symbol itself. A few spots still need the unrelocated address. For these, we introduce MSYMBOL_VALUE_RAW_ADDRESS. As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS, which computes the address of a bound minimal symbol. This just does the obvious thing with the fields. Note that this change does not actually enable program space independence. That requires more changes to gdb. However, to ensure that these changes compile properly, this patch does add the needed section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has no effect at runtime by multiplying the offset by 0. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_main_name): Update.

2014-01-14psymtab cleanup patch 3/3Doug Evans1-4/+5
This last patch removes "partial" from the names of expand_partial_symbol_names and map_partial_symbol_filenames. It also renames expand_partial_symbol_names to match the struct quick_symbol_functions "method" that it wraps: expand_symtabs_matching. This patch also adds two parameters to expand_symtabs_matching so that it can fully wrap the underlying quick_symbol_functions method. This makes it usable in more places. I thought of having a cover function that still had the same signature as the old expand_partial_symbol_names function, but I couldn't think of a good name, and it wasn't clear it was worth it anyway. * symfile.h (expand_symtabs_matching): Renamed from expand_partial_symbol_names.

2014-01-14psymtab cleanup patch 1/3Doug Evans1-0/+6
This is the first of a set of three patches to cleanup psymtab.c a bit. Basically, these two functions do not belong in psymtab.c: expand_partial_symbol_names, map_partial_symbol_filenames, and "partial" does not belong in the function name. This first patch moves them to a better location. The second patch adds some typedefs for function parameters to quick_symbol_functions.expand_symtabs_matching. The third patch removes "partial" from the function names and uses them in more places. * psymtab.c (expand_partial_symbol_names): Delete, moved to symfile.c.

2013-12-06remove some sym_probe_fns methodsTom Tromey1-34/+0
While looking into the probe API, it seemed to me that there were a number of methods in sym_probe_fns that were not needed. This patch removes them. Specifically, it seems to me that sym_probe_fns ought to be concerned with the API for constructing the probes. Any method relating to some aspect of an individual probe can be handled via the probe's own vtable. That is, the double indirection here doesn't seem useful -- it certainly isn't in fact used, but also I couldn't think of a potential use. 2013-12-06 Tom Tromey <tromey@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use get_probe_argument_count and evaluate_probe_argument. * elfread.c (elf_get_probe_argument_count) (elf_can_evaluate_probe_arguments, elf_evaluate_probe_argument) (elf_compile_to_ax): Remove.
