2014-12-05Unify lookup_symbol_in_objfile_symtabsJan Kratochvil1-17/+10
That's right, block_lookup_symbol_primary()'s additional requirement over block_lookup_symbol() is: Function is useful if one iterates all global/static blocks of an objfile. Which is satisfied both in lookup_symbol_in_objfile_symtabs() and in lookup_global_symbol_from_objfile() thanks to their's ALL_OBJFILE_COMPUNITS. In fact after reverting that ba715d7fe49c8a59660fbd571b935b29eb7cfbdb above the lines of code were exactly the same. So instead of accelerating both lookup_symbol_in_objfile_symtabs() and lookup_global_symbol_from_objfile() I just accelerated lookup_symbol_in_objfile_symtabs() and I am proposing to reuse lookup_symbol_in_objfile_symtabs() in lookup_global_symbol_from_objfile() instead. In fact such unification would already save some lines of code even before the checked-in acceleration patch above. gdb/ChangeLog 2014-12-05 Jan Kratochvil <jan.kratochvil@redhat.com> * symtab.c (lookup_symbol_in_objfile_symtabs): New declaration. (lookup_global_symbol_from_objfile): Call it.
2014-12-05Remove const from many struct objfile *Jan Kratochvil1-5/+4
I am just not sure if we should go the route of struct objfile * -> const struct objfile * or the other way of: const struct objfile * -> struct objfile * Normally const adding is better but here I do not see much useful to have any struct objfile * const and then it just causes pointer compatibility problems.

2014-12-04Accelerate lookup_symbol_aux_objfile 85xJan Kratochvil1-1/+3
During debugging I get 10-30 seconds for a response to simple commands like: (gdb) print vectorvar.size() With this patch the performance gets to 1-2 seconds which is somehow acceptable. The problem is that dwarf2_gdb_index_functions.lookup_symbol (quick_symbol_functions::lookup_symbol) may return (and returns) NULL even for symbols which are present in .gdb_index but which can be found in already expanded symtab. But searching in the already expanded symtabs is just too slow when there are 400000+ expanded symtabs. There would be needed some single global hash table for each objfile so that one does not have to iterate all symtabs. Which .gdb_index could perfectly serve for, just its lookup_symbol() would need to return authoritative yes/no answers. Even after such fix these two simple patches are useful for example for non-.gdb_index files. One can reproduce the slugging interactive GDB performance with: #include <string> using namespace std; string var; class C { public: void m() {} }; int main() { C c; c.m(); return 0; } g++ -o slow slow.C -Wall -g $(pkg-config --libs gtkmm-3.0) gdb ./slow -ex 'b C::m' -ex 'maintenance set per-command space' -ex 'maintenance set per-command symtab' -ex 'maintenance set per-command time' -ex r [...] (gdb) p <tab><tab> Display all 183904 possibilities?

But not always, I have found there typedef symbols, there can IMO be optimized-out static variables etc. Neither of the patches should cause any visible behavior change. gdb/ChangeLog 2014-12-04 Jan Kratochvil <jan.kratochvil@redhat.com> * block.c (block_lookup_symbol_primary): New function. * block.h (block_lookup_symbol_primary): New declaration. * symtab.c (lookup_symbol_in_objfile_symtabs): Assert BLOCK_INDEX.

For my standard benchmark this patch gets back 44MB of memory when gdb starts. [There's still ~440MB of memory used by the demangled ELF symbols of this benchmark, but that's another topic.] When the improved templated support is added, I wonder if this can be moved to struct symbol. Hmmm, we already have a special version of struct symbol for templates (struct template_symbol). gdb/ChangeLog: * symtab.c (symbol_init_cplus_specific): Delete.

2014-11-20Split struct symtab into two: struct symtab and compunit_symtab.Doug Evans1-143/+160
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 *".

Basically the problem is that "symtab" is ambiguous. Is it the primary symtab (where we canonically think of blockvectors as being stored) or is it for a specific file (where each file's line table is stored) ? gdb_disassembly wants the symtab that contains the line table but is instead getting the primary symtab. gdb/ChangeLog: PR symtab/17559 * symtab.c (find_pc_line_symtab): New function. * symtab.h (find_pc_line_symtab): Declare. * disasm.c (gdb_disassembly): Call find_pc_line_symtab instead of find_pc_symtab. * tui/tui-disasm.c (tui_set_disassem_content): Ditto. * tui/tui-hooks.c (tui_selected_frame_level_changed_hook): Ditto. * tui/tui-source.c (tui_vertical_source_scroll): Ditto. * tui/tui-win.c (make_visible_with_new_height): Ditto. * tui/tui-winsource.c (tui_horizontal_source_scroll): Ditto.

2014-11-15expand_symtab_containing_pc: Renamed from find_pc_sect_symtab_via_partial.Doug Evans1-10/+10
This patch just renames one function. Its only caller is in stack.c where we're printing a backtrace with non-zero info_verbose and we want to make sure all the needed symtabs are expanded before printing the backtrace so that debug symbol reading messages don't pollute the backtrace. I think the new name of the function makes clearer to the reader what is going on. gdb/ChangeLog: * symtab.c (expand_symtab_containing_pc): Renamed from find_pc_sect_symtab_via_partial. All callers updated.
2014-11-10PR 17564: Fix objfile search order for static symbols.Doug Evans1-54/+43
When searching static symbols, gdb would search over all expanded symtabs of all objfiles, and if that fails only then would it search all partial/gdb_index tables of all objfiles. This means that the user could get a random instance of the symbol depending on what symtabs have been previously expanded. Now the search is consistent, searching each objfile completely before proceeding to the next one. gdb/ChangeLog: PR symtab/17564 * symtab.c (lookup_symbol_in_all_objfiles): Delete.

2014-11-07Revert old nexti prologue check and eliminate in_prologuePedro Alves1-73/+0
The in_prologue check in the nexti code is obsolete; this commit removes that, and then removes the in_prologue function as nothing else uses it. Looking at the code in GDB that makes use in_prologue, all we find is this one caller: if ((ecs->event_thread->control.step_over_calls == STEP_OVER_NONE) || ((ecs->event_thread->control.step_range_end == 1) && in_prologue (gdbarch, ecs->event_thread->prev_pc, ecs->stop_func_start))) { /* I presume that step_over_calls is only 0 when we're supposed to be stepping at the assembly language level ("stepi"). Just stop. */ /* Also, maybe we just did a "nexti" inside a prolog, so we thought it was a subroutine call but it was not. Stop as well. FENN */ /* And this works the same backward as frontward. MVS */ end_stepping_range (ecs); return; } This was added by: commit 100a02e1deec2f037a15cdf232f026dc79763bf8 ... From Fernando Nasser: * infrun.c (handle_inferior_event): Handle "nexti" inside function prologues. The mailing list thread is here: https://sourceware.org/ml/gdb-patches/2001-01/msg00047.html Not much discussion there, and no test, but looking at the code around what was patched in that revision, we see that the checks that detect whether the program has just stepped into a subroutine didn't rely on the unwinders at all back then. From 'git show 100a02e1:gdb/infrun.c': if (stop_pc == ecs->stop_func_start /* Quick test */ || (in_prologue (stop_pc, ecs->stop_func_start) && ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ !IN_SOLIB_RETURN_TRAMPOLINE (stop_pc, ecs->stop_func_name)) || IN_SOLIB_CALL_TRAMPOLINE (stop_pc, ecs->stop_func_name) || ecs->stop_func_name == 0) { /* It's a subroutine call. */ if ((step_over_calls == STEP_OVER_NONE) || ((step_range_end == 1) && in_prologue (prev_pc, ecs->stop_func_start))) { /* I presume that step_over_calls is only 0 when we're supposed to be stepping at the assembly language level ("stepi"). Just stop. */ /* Also, maybe we just did a "nexti" inside a prolog, so we thought it was a subroutine call but it was not. Stop as well. FENN */ stop_step = 1; print_stop_reason (END_STEPPING_RANGE, 0); stop_stepping (ecs); return; } Stripping the IN_SOLIB_RETURN_TRAMPOLINE checks for simplicity, we had: if (stop_pc == ecs->stop_func_start /* Quick test */ || in_prologue (stop_pc, ecs->stop_func_start) || ecs->stop_func_name == 0) { /* It's a subroutine call. */ That is, detecting a subroutine call was based on prologue detection back then. So the in_prologue check in the current tree only made sense back then as it was undoing a bad decision the in_prologue check that used to exist above did. Today, the check for a subroutine call relies on frame ids instead, which are stable throughout the function. So we can just remove the in_prologue check for nexti, and the whole in_prologue function along with it. Tested on x86_64 Fedora 20, and also by nexti-ing manually a prologue. gdb/ 2014-11-07 Pedro Alves <palves@redhat.com> * infrun.c (process_event_stop_test) <subroutine check>: Don't check if we did a "nexti" inside a prologue. * symtab.c (in_prologue): Delete function. * symtab.h (in_prologue): Delete declaration.

There is another function, lookup_symbol_aux_block, and the names lookup_block_symbol and lookup_symbol_aux_block don't convey any real difference between them.

2014-04-14Remove symbol_matches_domain. This fixesKeith Seitz1-29/+31
PR c++/16253. symbol_matches_domain was permitting searches for a VAR_DOMAIN symbol to also match STRUCT_DOMAIN symbols for languages like C++ where STRUCT_DOMAIN symbols also define a typedef of the same name, e.g., "struct foo {}" introduces a typedef of the name "foo". Problems occur if there exists both a VAR_DOMAIN and STRUCT_DOMAIN symbol of the same name. Then it is essentially a race between which symbol is found first. The other symbol is obscurred. [This is a relatively common idiom: enum e { ... } e;] This patchset moves this "language defines a typedef" logic to lookup_symbol[_in_language], looking first for a symbol in the given domain and falling back to searching STRUCT_DOMAIN when/if appropriate. 2014-04-14 Keith Seitz <keiths@redhat.com> PR c++/16253 * ada-lang.c (ada_symbol_matches_domain): Moved here and renamed from symbol_matches_domain in symtab.c.

2014-03-03change probes to be program-space-independentTom Tromey1-9/+1
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 Tromey1-28/+30
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.

2014-02-26use bound_minsym as result for lookup_minimal_symbol et alTom Tromey1-1/+1
This patch changes a few minimal symbol lookup functions to return a bound_minimal_symbol rather than a pointer to the minsym. This change helps prepare gdb for computing a minimal symbol's address at the point of use. Note that this changes even those functions that ostensibly search a single objfile. That was necessary because, in fact, those functions can search an objfile and its separate debug objfiles; and it is important for the caller to know in which objfile the minimal symbol was actually found.
