2015-03-11Implement remote_bfd_iovec_statGary Benson1-8/+9
This commit adds a new packet "vFile:fstat:" to the remote protocol that can be used by to retrieve information about files that have been previously opened using vFile:open. vFile:fstat: support is added to GDB, and remote_bfd_iovec_stat is implemented using it. If vFile:fstat: is not supported by the remote GDB creates a dummy result by zeroing the supplied stat structure and setting its st_size field to INT_MAX. This mimics GDB's previous behaviour, with the exception that GDB did not previously zero the structure so all other fields would have been returned unchanged, which is to say very likely populated with random values from the stack. gdb/ChangeLog: * remote-fileio.h (remote_fileio_to_host_stat): New declaration. * remote-fileio.c (remote_fileio_to_host_uint): New function.

2014-11-28Use lstat unconditionallyYao Qi1-2/+0
Since lstat gnulib module is imported, we can use it unconditionally. lstat usage was introduced by this patch https://sourceware.org/ml/gdb-patches/2012-01/msg00390.html during the review, it was suggested to import gnulib lstat module, but we didn't do that. gdb: 2014-11-28 Yao Qi <yao@codesourcery.com> * configure.ac (AC_CHECK_FUNCS): Remove lstat. * config.in, configure: Regenerate. * symfile.c (find_separate_debug_file_by_debuglink): Remove code checking HAVE_LSTAT is defined.
2014-11-20Split struct symtab into two: struct symtab and compunit_symtab.Doug Evans1-26/+65
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 *".

2014-06-16"$ gdb PROGRAM" vs "(gdb) file PROGRAM" difference; warn on failure to ↵Pedro Alves1-5/+5
remove breakpoint. Turns out there's a difference between loading the program with "gdb PROGRAM", vs loading it with "(gdb) file PROGRAM". The latter results in the objfile ending up with OBJF_USERLOADED set, while not with the former. (That difference seems bogus, but still that's not the point of this patch. We can revisit that afterwards.) The new code that suppresses breakpoint removal errors for add-symbol-file objects ends up being too greedy: /* In some cases, we might not be able to remove a breakpoint in a shared library that has already been removed, but we have not yet processed the shlib unload event. Similarly for an unloaded add-symbol-file object - the user might not yet have had the chance to remove-symbol-file it. shlib_disabled will be set if the library/object has already been removed, but the breakpoint hasn't been uninserted yet, e.g., after "nosharedlibrary" or "remove-symbol-file" with breakpoints always-inserted mode. */ if (val && (bl->loc_type == bp_loc_software_breakpoint && (bl->shlib_disabled || solib_name_from_address (bl->pspace, bl->address) || userloaded_objfile_contains_address_p (bl->pspace, bl->address)))) val = 0; as it turns out that OBJF_USERLOADED can be set for objfiles loaded by some other means not add-symbol-file. In this case, symbol-file (or "file", which is really just "exec-file"+"symbol-file"). Recall that add-symbol-file is documented as: (gdb) help add-symbol-file Load symbols from FILE, assuming FILE has been dynamically loaded. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ And it's the "dynamically loaded" aspect that the breakpoint.c code cares about. So make add-symbol-file set OBJF_SHARED on its objfiles too, and tweak the breakpoint.c code to look for OBJF_SHARED instead of OBJF_USERLOADED. This restores back the missing breakpoint removal warning when we let sss-bp-on-user-bp-2.exp run on native GNU/Linux (https://sourceware.org/ml/gdb-patches/2014-06/msg00335.html): (gdb) PASS: gdb.base/sss-bp-on-user-bp-2.exp: define stepi_del_break stepi_del_break warning: Error removing breakpoint 3 (gdb) FAIL: gdb.base/sss-bp-on-user-bp-2.exp: stepi_del_break I say "restores" because this was GDB's behavior in 7.7 and earlier. And, likewise, "file" with no arguments only started turning breakpoints set in the main executable to "<pending>" with the remote-symbol-file patch (63644780).

Target sections added by the add-symbol-file-from-memory command are not removed when the process exits. In fact, they are not removed, at all. This causes GDB to crash in gdb.base/break-interp.exp. Change the owner of those target sections to the object file generated in symbol_file_add_from_memory and generalize the free_objfile observer in symfile.c to remove target sections of any freed object file.

2014-02-26move minimal symbols to per-bfdTom Tromey1-6/+1
Now that minimal symbols are independent of the program space, we can move them to the per-BFD object. This lets us save memory in the multi-inferior case; and, once the symbol readers are updated, time. The other prerequisite for this move is that all the objects referred to by the minimal symbols have a lifetime at least as long as the per-BFD object. I think this is satisfied partially by this patch (moving the copied names there) and partially by earlier patches moving the demangled name hash. This patch contains a bit of logic to avoid creating new minimal symbols if they have already been read for a given BFD. This allows us to avoid trying to update all the symbol readers for this condition. At first glance this may seem like a hack, but some symbol readers mix psym and minsym reading, and would require logic just like this regardless -- and it is simpler and less error-prone to just do the work in a central spot. 2014-02-26 Tom Tromey <tromey@redhat.com> * minsyms.c (lookup_minimal_symbol, iterate_over_minimal_symbols) (lookup_minimal_symbol_text, lookup_minimal_symbol_by_pc_name) (lookup_minimal_symbol_solib_trampoline) (lookup_minimal_symbol_by_pc_section_1) (lookup_minimal_symbol_and_objfile): Update.

2014-02-26start change to progspace independenceTom Tromey1-5/+4
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 Tromey1-7/+8
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. The bulk of this patch is mechanical. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_update_initial_language): Update.

2014-02-26change minsym representationTom Tromey1-3/+3
In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.

2014-01-14psymtab cleanup patch 3/3Doug Evans1-6/+9
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.

2014-01-07Remove duplicated #include's from GDBHonggyu Kim1-1/+0
This patch simply removes duplicated #include statements in the gdb/ directory. If there are two duplicated #include statements, this patch keeps the first #include and removes the second. Those duplicates have been found by using the checkincludes.pl tool from the Linux kernel and double checked manually once again if the #include statements are affected by #ifdef macros. 2014-01-06 Honggyu Kim <hong.gyu.kim@lge.com> * ada-lang.c: Remove duplicated include statements. * alphabsd-nat.c: Ditto. * amd64-darwin-tdep.c: Ditto. * amd64fbsd-nat.c: Ditto. * auto-load.c: Ditto. * ax-gdb.c: Ditto. * breakpoint.c: Ditto. * dbxread.c: Ditto. * fork-child.c: Ditto. * gdb_usleep.c: Ditto. * i386-darwin-tdep.c: Ditto. * i386fbsd-nat.c: Ditto. * infcmd.c: Ditto. * inferior.c: Ditto. * jv-lang.c: Ditto. * linux-nat.c: Ditto. * linux-tdep.c: Ditto. * m68kbsd-nat.c: Ditto. * m68klinux-nat.c: Ditto. * microblaze-tdep.c: Ditto. * mips-linux-tdep.c: Ditto. * mn10300-tdep.c: Ditto. * nto-tdep.c: Ditto. * opencl-lang.c: Ditto. * osdata.c: Ditto. * printcmd.c: Ditto. * regcache.c: Ditto. * remote-m32r-sdi.c: Ditto. * remote.c: Ditto. * symfile.c: Ditto. * symtab.c: Ditto. * tilegx-linux-nat.c: Ditto. * tilegx-tdep.c: Ditto. * tracepoint.c: Ditto. * valops.c: Ditto. * vaxbsd-nat.c: Ditto. * windows-nat.c: Ditto. * xtensa-tdep.c: Ditto.

2013-11-13crash while re-reading symbols from objfile on ppc-aix.Joel Brobecker1-2/+6
This patch aims at fixing the following problem, where the user: . debugs its program . makes a modification and rebuilds it *without exiting the debugger* . returns to its debugging session and restarts the inferior In that situation, the debugger notices that the underlying executable has changed and that re-reading its symbols is needed. Shortly after displaying a message informing the user of the situation, GDB crashes: (gdb) run [...] `/[...]/dest' has changed; re-reading symbols. zsh: 13434922 segmentation fault (core dumped) The crash occurs while trying to allocate some memory on the bfd_bfd obstack. But, at some point in time, the whole obstack data gets corrupted, nullified. So the memory allocation fails trying to call a function at a NULL address. (side note: when debugging GDB in GDB, top-gdb reports a SIGILL, while the shell makes it look like it was a SIGSEGV - the discrepancy is not critical to the investigation and therefore was not explored) The corruption occurred because the region where the per_bfd data got free'ed nearly after it got allocated! This is what happens, in chronological order (see reread_symbols): 1. GDB notices that the executable has changed, decides to re-read its symbols. 2. Opens a new bfd, unrefs the old one 3. Calls set_objfile_per_bfd (objfile); 4. Re-initializes the objfile's obstack: obstack_init (&objfile->objfile_obstack); I think that the normal behavior for set_objfile_per_bfd would be to search for already-allocated shared per_bfd data, and allocate new one if not found. The critical difference between a platform such as x86_64-linuxe where it works, and ppc-aix, where it doesn't lies in the fact that bfd-data sharing is not activated on ppc-aix, and as a result, the per-bfd data gets allocated on the objfile's obstack instead of in the bfd objalloc: /* If the object requires gdb to do relocations, we simply fall back to not sharing data across users. These cases are rare enough that this seems reasonable. */ if (abfd != NULL && !gdb_bfd_requires_relocations (abfd)) { storage = bfd_zalloc (abfd, sizeof (struct objfile_per_bfd_storage)); set_bfd_data (abfd, objfiles_bfd_data, storage); } else storage = OBSTACK_ZALLOC (&objfile->objfile_obstack, struct objfile_per_bfd_storage); Allocating that per_bfd storage is of course nearly useless since we end up free-ing right after in step (4) above. Eventually, the memory region ends up being re-used, hence the corruption leading to the crash. This fix was simply to move the call to set_objfile_per_bfd after the objfile's obstack re-initialization. gdb/ChangeLog: * symfile.c (reread_symbols): Move call to set_objfile_per_bfd after re-initialization of OBJFILE's obstack.

This moves the demangled_names_hash from the objfile into the per-BFD object. This is part of the objfile splitting project. The demangled names hash is independent of the program space.

2013-08-20move gdbarch object from objfile to per-BFDTom Tromey1-2/+2
This moves the "gdbarch" field from the objfile into the BFD. This field's value is derived from the BFD and is immutable over the lifetime of the BFD. This makes it a reasonable candidate for pushing into the per-BFD object. This is part of the long-term objfile splitting project. In the long run I think this patch will make it simpler to moves types from the objfile to the per-BFD object; but the patch makes sense as a minor cleanup by itself.
