2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-08-03Use gdb_bfd_ref_ptr in objfileTom Tromey1-1/+1
This changes struct objfile to use a gdb_bfd_ref_ptr. In addition to removing some manual memory management, this fixes a use-after-free that was introduced by the registry rewrite series. The issue there was that, in some cases, registry shutdown could refer to memory that had already been freed. This help fix the bug by delaying the destruction of the BFD reference (and thus the per-bfd object) until after the registry has been shut down.
2022-03-29Unify gdb printf functionsTom Tromey1-9/+9
Now that filtered and unfiltered output can be treated identically, we can unify the printf family of functions. This is done under the name "gdb_printf". Most of this patch was written by script.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-12-29Use gdb_stdlog for separate debug file loggingTom Tromey1-8/+10
This changes the separate debug file logging code (spread across two files) to use gdb_stdlog for its output. This is part of PR gdb/7233. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=7233
2021-10-19Fix PR gdb/17917 Lookup build-id in remote binariesDaniel Black1-9/+12
GDB doesn't support loading debug files using build-id from remote target filesystems. This is the case when gdbserver attached to a process and a gdb target remote occurs over tcp. With this change we make build-id lookups possible: (gdb) show debug-file-directory The directory where separate debug symbols are searched for is "/usr/local/lib/debug". (gdb) set debug-file-directory /usr/lib/debug (gdb) show sysroot The current system root is "target:".

2021-10-03gdb: make string-like set show commands use std::string variableSimon Marchi1-2/+2
String-like settings (var_string, var_filename, var_optional_filename, var_string_noescape) currently take a pointer to a `char *` storage variable (typically global) that holds the setting's value. I'd like to "mordernize" this by changing them to use an std::string for storage. An obvious reason is that string operations on std::string are often easier to write than with C strings. And they avoid having to do any manual memory management. Another interesting reason is that, with `char *`, nullptr and an empty string often both have the same meaning of "no value". String settings are initially nullptr (unless initialized otherwise). But when doing "set foo" (where `foo` is a string setting), the setting now points to an empty string. For example, solib_search_path is nullptr at startup, but points to an empty string after doing "set solib-search-path". This leads to some code that needs to check for both to check for "no value". Or some code that converts back and forth between NULL and "" when getting or setting the value. I find this very error-prone, because it is very easy to forget one or the other. With std::string, we at least know that the variable is not "NULL". There is only one way of representing an empty string setting, that is with an empty string. I was wondering whether the distinction between NULL and "" would be important for some setting, but it doesn't seem so. If that ever happens, it would be more C++-y and self-descriptive to use optional<string> anyway. Actually, there's one spot where this distinction mattered, it's in init_history, for the test gdb.base/gdbinit-history.exp. init_history sets the history filename to the default ".gdb_history" if it sees that the setting was never set - if history_filename is nullptr. If history_filename is an empty string, it means the setting was explicitly cleared, so it leaves it as-is. With the change to std::string, this distinction doesn't exist anymore. This can be fixed by moving the code that chooses a good default value for history_filename to _initialize_top. This is ran before -ex commands are processed, so an -ex command can then clear that value if needed (what gdb.base/gdbinit-history.exp tests). Another small improvement, in my opinion is that we can now easily give string parameters initial values, by simply initializing the global variables, instead of xstrdup-ing it in the _initialize function. In Python and Guile, when registering a string-like parameter, we allocate (with new) an std::string that is owned by the param_smob (in Guile) and the parmpy_object (in Python) objects. This patch started by changing all relevant add_setshow_* commands to take an `std::string *` instead of a `char **` and fixing everything that failed to build. That includes of course all string setting variable and their uses. string_option_def now uses an std::string also, because there's a connection between options and settings (see add_setshow_cmds_for_options). The add_path function in source.c is really complex and twisted, I'd rather not try to change it to work on an std::string right now. Instead, I added an overload that copies the std:string to a `char *` and back. This means more copying, but this is not used in a hot path at all, so I think it is acceptable.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-7/+7
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

This patch uses new BFD support for detecting build-ids in core files. After this patch, it is possible to run gdb with only the core file, and gdb will automatically load the executable and debug info [example from tests]: $ gdb -nx -q (gdb) core-file corefile-buildid.core [New LWP 29471] Reading symbols from gdb.base/corefile-buildid/debugdir-exec/.build-id/36/fe5722c5a7ca3ac746a84e223c6a2a69193a24... Core was generated by `outputs/gdb.base/coref'. Program terminated with signal SIGABRT, Aborted. (gdb) This work is based on functionality available in Fedora originally written by Jan Kratochvil. Regression tested on buildbot. gdb/ChangeLog: 2019-12-07 Keith Seitz <keiths@redhat.com> * build-id.c (build_id_bfd_get): Permit bfd_core, too. (build_id_to_debug_bfd): Make static, rewriting to use build_id_to_bfd_suffix. (build_id_to_bfd_suffix): Copy of build_id_to_debug_bfd, adding `suffix' parameter. Append SUFFIX to file names when searching for matching files. (build_id_to_debug_bfd): Use build_id_to_bfd_suffix. (build_id_to_exec_bfd): Likewise. * build-id.h (build_id_to_debug_bfd): Clarify that function searches for BFD of debug info file. (build_id_to_exec_bfd): Declare. * corelow.c: Include build-id.h. (locate_exec_from_corefile_build_id): New function. (core_target_open): If no executable BFD is found, search for a core file BFD using build-id. gdb/testsuite/ChangeLog: 2019-12-07 Keith Seitz <keiths@redhat.com> * gdb.base/corefile-buildid-shlib-shr.c: New file. * gdb.base/corefile-buildid-shlib.c: New file. * gdb.base/corefile-buildid.c: New file. * gdb.base/corefile-buildid.exp: New file.

2019-07-09Rename common to gdbsupportTom Tromey1-1/+1
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. *

2019-04-06Revert the header-sorting patchTom Tromey1-5/+3
Andreas Schwab and John Baldwin pointed out some bugs in the header sorting patch; and I noticed that the output was not correct when limited to a subset of files (a bug in my script). So, I'm reverting the patch. I may try again after fixing the issues pointed out. gdb/ChangeLog 2019-04-05 Tom Tromey <tom@tromey.com> Revert the header-sorting patch. * ft32-tdep.c: Revert. * frv-tdep.c: Revert. * frv-linux-tdep.c: Revert. * frame.c: Revert. * frame-unwind.c: Revert. * frame-base.c: Revert. * fork-child.c: Revert. * findvar.c: Revert. * findcmd.c: Revert. * filesystem.c: Revert. * filename-seen-cache.h: Revert. * filename-seen-cache.c: Revert. * fbsd-tdep.c: Revert. * fbsd-nat.h: Revert. * fbsd-nat.c: Revert. * f-valprint.c: Revert. * f-typeprint.c: Revert. * f-lang.c: Revert. * extension.h: Revert. * extension.c: Revert. * extension-priv.h: Revert. * expprint.c: Revert. * exec.h: Revert. * exec.c: Revert. * exceptions.c: Revert. * event-top.c: Revert. * event-loop.c: Revert. * eval.c: Revert. * elfread.c: Revert. * dwarf2read.h: Revert. * dwarf2read.c: Revert. * dwarf2loc.c: Revert. * dwarf2expr.h: Revert. * dwarf2expr.c: Revert. * dwarf2-frame.c: Revert. * dwarf2-frame-tailcall.c: Revert. * dwarf-index-write.h: Revert. * dwarf-index-write.c: Revert. * dwarf-index-common.c: Revert. * dwarf-index-cache.h: Revert. * dwarf-index-cache.c: Revert. * dummy-frame.c: Revert. * dtrace-probe.c: Revert. * disasm.h: Revert. * disasm.c: Revert. * disasm-selftests.c: Revert. * dictionary.c: Revert. * dicos-tdep.c: Revert. * demangle.c: Revert. * dcache.h: Revert. * dcache.c: Revert. * darwin-nat.h: Revert. * darwin-nat.c: Revert. * darwin-nat-info.c: Revert. * d-valprint.c: Revert. * d-namespace.c: Revert. * d-lang.c: Revert. * ctf.c: Revert. * csky-tdep.c: Revert. * csky-linux-tdep.c: Revert. * cris-tdep.c: Revert. * cris-linux-tdep.c: Revert. * cp-valprint.c: Revert. * cp-support.c: Revert. * cp-namespace.c: Revert. * cp-abi.c: Revert. * corelow.c: Revert. * corefile.c: Revert. * continuations.c: Revert. * completer.h: Revert. * completer.c: Revert. * complaints.c: Revert. * coffread.c: Revert. * coff-pe-read.c: Revert. * cli-out.h: Revert. * cli-out.c: Revert. * charset.c: Revert. * c-varobj.c: Revert. * c-valprint.c: Revert. * c-typeprint.c: Revert. * c-lang.c: Revert. * buildsym.c: Revert. * buildsym-legacy.c: Revert. * build-id.h: Revert. * build-id.c: Revert. * btrace.c: Revert. * bsd-uthread.c: Revert. * breakpoint.h: Revert. * breakpoint.c: Revert. * break-catch-throw.c: Revert. * break-catch-syscall.c: Revert. * break-catch-sig.c: Revert. * blockframe.c: Revert. * block.c: Revert. * bfin-tdep.c: Revert. * bfin-linux-tdep.c: Revert. * bfd-target.c: Revert. * bcache.c: Revert. * ax-general.c: Revert. * ax-gdb.h: Revert. * ax-gdb.c: Revert. * avr-tdep.c: Revert. * auxv.c: Revert. * auto-load.c: Revert. * arm-wince-tdep.c: Revert. * arm-tdep.c: Revert. * arm-symbian-tdep.c: Revert. * arm-pikeos-tdep.c: Revert. * arm-obsd-tdep.c: Revert. * arm-nbsd-tdep.c: Revert. * arm-nbsd-nat.c: Revert. * arm-linux-tdep.c: Revert. * arm-linux-nat.c: Revert. * arm-fbsd-tdep.c: Revert. * arm-fbsd-nat.c: Revert. * arm-bsd-tdep.c: Revert. * arch-utils.c: Revert. * arc-tdep.c: Revert. * arc-newlib-tdep.c: Revert. * annotate.h: Revert. * annotate.c: Revert. * amd64-windows-tdep.c: Revert. * amd64-windows-nat.c: Revert. * amd64-tdep.c: Revert. * amd64-sol2-tdep.c: Revert. * amd64-obsd-tdep.c: Revert. * amd64-obsd-nat.c: Revert. * amd64-nbsd-tdep.c: Revert. * amd64-nbsd-nat.c: Revert. * amd64-nat.c: Revert. * amd64-linux-tdep.c: Revert. * amd64-linux-nat.c: Revert. * amd64-fbsd-tdep.c: Revert. * amd64-fbsd-nat.c: Revert. * amd64-dicos-tdep.c: Revert. * amd64-darwin-tdep.c: Revert. * amd64-bsd-nat.c: Revert. * alpha-tdep.c: Revert. * alpha-obsd-tdep.c: Revert. * alpha-nbsd-tdep.c: Revert. * alpha-mdebug-tdep.c: Revert. * alpha-linux-tdep.c: Revert. * alpha-linux-nat.c: Revert. * alpha-bsd-tdep.c: Revert. * alpha-bsd-nat.c: Revert. * aix-thread.c: Revert. * agent.c: Revert. * addrmap.c: Revert. * ada-varobj.c: Revert. * ada-valprint.c: Revert. * ada-typeprint.c: Revert. * ada-tasks.c: Revert. * ada-lang.c: Revert. * aarch64-tdep.c: Revert. * aarch64-ravenscar-thread.c: Revert. * aarch64-newlib-tdep.c: Revert. * aarch64-linux-tdep.c: Revert. * aarch64-linux-nat.c: Revert. * aarch64-fbsd-tdep.c: Revert. * aarch64-fbsd-nat.c: Revert. * aarch32-linux-nat.c: Revert.

2019-02-22Look for build-id-based separate debug files under the sysrootSimon Marchi1-43/+72
When looking for a separate debug file that matches a given build-id, GDB only looks in the host's debug dir (typically /usr/lib/debug). This patch makes it look in the sysroot as well. This is to match the behavior of GDB when using debuglink-based separate debug files, introduced in : 402d2bfec42 ("Look for separate debug files in debug directories under a sysroot.") In the following example, my sysroot is "/tmp/sysroot" and I am trying to load symbols for /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so. This is the current behavior: (gdb) file /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so Reading symbols from /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so... Looking for separate debug info (build-id) for /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so Trying /usr/lib/debug/.build-id/f3/d6594d2600e985812cd4ba2ad083ac2aceae22.debug... no, unable to compute real path <snip> (No debugging symbols found in /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so) With this patch: (gdb) file /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so Reading symbols from /tmp/sysroot/usr/lib/arm-linux-gnueabihf/gconv/EBCDIC-AT-DE.so...

Reading symbols from /tmp/sysroot/usr/lib/debug/.build-id/f3/d6594d2600e985812cd4ba2ad083ac2aceae22.debug... In the original code, there is a suspicious "abfd.release ()" in build_id_to_debug_bfd, that I don't understand. If a file with the right name exists but its build-id note doesn't match, we release (leak) our reference, meaning the file will stay open? I removed it in the new code, so that the reference is dropped if we end up not using that file. I tested briefly by corrupting a separate debug file to trigger this code, nothing exploded. gdb/ChangeLog: * build-id.c (build_id_to_debug_bfd_1): New function. (build_id_to_debug_bfd): Look for separate debug file in sysroot.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-12-26Improve "set debug separate-debug-file"Simon Marchi1-4/+27
"set debug separate-debug-file" shows which candidates are considered, when trying to find separate debug info. But it's not clear if GDB used a certain candidate, and if not, why not. This patch adds some precision: Before: Looking for separate debug info (debug link) for /lib/x86_64-linux-gnu/libc.so.6 Trying /lib/x86_64-linux-gnu/libc-2.23.so Trying /lib/x86_64-linux-gnu/.debug/libc-2.23.so Trying /usr/lib/debug//lib/x86_64-linux-gnu/libc-2.23.so After: Looking for separate debug info (debug link) for /lib/x86_64-linux-gnu/libc.so.6 Trying /lib/x86_64-linux-gnu/libc-2.23.so... no, same file as the objfile.

2018-03-02Make delim_string_to_char_ptr_vec return an std::vectorSimon Marchi1-8/+5
This patch makes delim_string_to_char_ptr_vec and all related functions use std::vector of gdb::unique_xmalloc_ptr. This allows getting rid of make_cleanup_free_char_ptr_vec. Returning a vector of unique_xmalloc_ptr instead of std::string allows to minimize the impacts on the calling code. We can evaluate later whether we could/should return a vector of std::strings instead. gdb/ChangeLog: * common/gdb_vecs.h (make_cleanup_free_char_ptr_vec): Remove.

2017-06-11Introduce "set debug separate-debug-file"Simon Marchi1-0/+7
I helped someone figure out why their separate debug info (debug link-based) was not found by gdb. It turns out that the debug file was not named properly. It made me realize that it is quite difficult to diagnose this kind of problems. This patch adds some debug output to show where GDB looks for those files, so that it should be (more) obvious to find what's wrong. Here's an example of the result, first with an example of unsuccessful lookup, and then a successful one. (gdb) set debug separate-debug-file on (gdb) file /usr/bin/gnome-calculator Reading symbols from /usr/bin/gnome-calculator...

2017-01-10Use class to manage BFD reference countsTom Tromey1-20/+10
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.

2015-09-25Add casts to memory allocation related callsSimon Marchi1-2/+5
Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Valgrind reports memory leaking from build_id_to_debug_bfd: ==7261== 88 bytes in 2 blocks are definitely lost in loss record 31,319 of 35,132 ==7261== at 0x4A06BCF: malloc (vg_replace_malloc.c:296) ==7261== by 0x32CA88A9B9: strdup (strdup.c:42) ==7261== by 0xFE62AB: lrealpath (lrealpath.c:88) ==7261== by 0x7F7AD6: build_id_to_debug_bfd (build-id.c:116) ==7261== by 0x7F7BB5: find_separate_debug_file_by_buildid (build-id.c:149) ==7261== by 0x6D9382: elf_symfile_read (elfread.c:1348) ==7261== by 0x777F02: read_symbols (symfile.c:875) ==7261== by 0x778505: syms_from_objfile_1 (symfile.c:1078) ==7261== by 0x778548: syms_from_objfile (symfile.c:1094) ==7261== by 0x778746: symbol_file_add_with_addrs (symfile.c:1191) ==7261== by 0x77893B: symbol_file_add_from_bfd (symfile.c:1280) ==7261== by 0x8E51E3: solib_read_symbols (solib.c:706) ==7261== by 0x8E58AF: solib_add (solib.c:1029) This occurs because commit 1be5090b in bfd, addressing PR 11983, started taking a copy of the input filename instead of directly caching it. It appears that this code was never updated to reflect that API change. This simple patch creates a cleanup to free the return value for lrealpath. gdb/ChangeLog * build-id.c (build_id_to_debug_bfd): Add cleanup to free return value from lrealpath.
2015-06-15Allow gdb to find debug symbols file by build-id for PE file format alsoJon Turney1-12/+9
This promotes BFD's struct elf_build_id to the generic struct bfd_build_id, populated when an ELF or PE BFD is read. gdb is updated to use that, and to use the build-id to find symbols for PE files also. There is currently no generic way to extract the build-id from an object file, perhaps an option to objdump to do this might make sense? On x86_64-pc-cygwin, gdb's sepdebug.exp changes: -# of unsupported tests 1 +# of expected passes 90 I don't seem to get consistent testsuite runs on i686-linux-gnu, but there don't appear to be any regressions. bfd/ChangeLog: 2015-06-10 Jon Turney <jon.turney@dronecode.org.uk> * elf-bfd.h : Remove struct elf_build_id. * bfd.c : Add struct bfd_build_id. * bfd-in2.h: Regenerate. * elf.c (elfobj_grok_gnu_build_id): Update to use bfd_build_id. * libpei.h: Add protoype and macros for bfd_XXi_slurp_codeview_record. * peXXigen.c (_bfd_XXi_slurp_codeview_record): Make public * peicode.h (pe_bfd_read_buildid): Add.

2013-10-08fix PR symtab/15597Tom Tromey1-0/+168
This patch fixes gdb PR symtab/15597. The bug is that the .gnu_debugaltlink section includes the build-id of the alt file, but gdb does not use it. This patch fixes the problem by changing gdb to do what it ought to always have done: verify the build id of the file found using the filename in .gnu_debugaltlink; and if that does not match, try to find the correct debug file using the build-id and debug-file-directory. This patch touches BFD. Previously, gdb had its own code for parsing .gnu_debugaltlink; I changed it to use the BFD functions after those were introduced. However, the BFD functions are incorrect -- they assume that .gnu_debugaltlink is formatted like .gnu_debuglink. However, it it is not. Instead, it consists of a file name followed by the build-id -- no alignment, and the build-id is not a CRC. Fixing this properly is a bit of a pain. But, because separate_alt_debug_file_exists just has a FIXME for the build-id case, I did not fix it properly. Instead I introduced a hack. This leaves BFD working just as well as it did before my patch. I'm willing to do something better here but I could use some guidance as to what. It seems that the build-id code in BFD is largely punted on. FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of BFD itself. I moved the build-id logic out of elfread.c and into a new file. This seemed cleanest to me. Writing a test case was a bit of a pain. I added a couple new features to the DWARF assembler to handle this. Built and regtested on x86-64 Fedora 18. * bfd-in2.h: Rebuild. * opncls.c (bfd_get_alt_debug_link_info): Add buildid_len parameter. Change type of buildid_out. Update. (get_alt_debug_link_info_shim): New function. (bfd_follow_gnu_debuglink): Use it. * Makefile.in (SFILES): Add build-id.c. (HFILES_NO_SRCDIR): Add build-id.h. * build-id.c: New file, largely from elfread.c. Modified most functions. * build-id.h: New file. * dwarf2read.c (dwarf2_get_dwz_file): Update for change to bfd_get_alt_debug_link_info. Verify dwz file's build-id. Search for dwz file using build-id. * elfread.c (build_id_bfd_get, build_id_verify) (build_id_to_debug_filename, find_separate_debug_file): Remove. * gdb.dwarf2/dwzbuildid.exp: New file. * lib/dwarf.exp (Dwarf::_section): Add "flags" and "type" parameters. (Dwarf::_defer_output): Change "section" parameter to "section_spec"; update. (Dwarf::gnu_debugaltlink, Dwarf::_note, Dwarf::build_id): New procs.
