------------------------------------------------------------------------------ (gdb) help save gdb-index Save a gdb-index file. Usage: save gdb-index [-dwarf-5] DIRECTORY No options create one file with .gdb-index extension for pre-DWARF-5 compatible .gdb_index section.

2017-12-08DWARF-5: .debug_names index producerJan Kratochvil1-6/+47
This adds a new "-dwarf-5" switch to "save gdb-index" that makes it generate index files with DWARF-5 .debug_names/.debug_str sections instead of GDB's own .gdb_index. We should probably add a command line option to contrib/gdb-add-index.sh (incl. cc-with-tweaks.sh) for the new -dwarf-5 GDB option, and a new target board to make it more convenient to exercise this.

2017-12-08cc-with-tweaks.sh: Use gdb-add-index.shJan Kratochvil1-17/+23
With DWARF-5 .debug_names, the commands to add the index to the symbol file are more complicated, as now also .debug_str needs to be modified. Currently, contrib/cc-with-tweaks.sh calls objcopy to handle the '-i' option instead of using contrib/gdb-add-index.sh which basically does the same. To help with .debug_names, this commit makes contrib/cc-with-tweaks.sh reuse contrib/gdb-add-index.sh instead. A problem this ran into is whether contrib/cc-with-tweaks.sh should fail or not when no index is produced. Currently, contrib/cc-with-tweaks.sh is more quiet (=successful) than contrib/gdb-add-index.sh and so with no further changes testsuite runs with an index would "regress". This commit tries to keep the behavior unchanged. Some cases still error with: Ada is not currently supported by the index But some cases (such as some trivial gdb.dwarf2/ testcases with no DWARF data to index) produce no index while the testcases still PASS now instead of: -PASS: gdb.arch/i386-bp_permanent.exp: stack pointer value matches +gdb compile failed, gdb-add-index.sh: No index was created for gdb/testsuite.unix.-m64/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent +gdb-add-index.sh: [Was there no debuginfo? Was there already an index?] +UNTESTED: gdb.arch/i386-bp_permanent.exp: failed to compile gdb/ChangeLog 2017-12-08 Jan Kratochvil <jan.kratochvil@redhat.com> Pedro Alves <palves@redhat.com> * contrib/cc-with-tweaks.sh: Change interpreter to bash, incl. initial comment.

2016-11-19ARI: Add detection of printf_vma and sprintf_vmaJoel Brobecker1-0/+16
We shouldn't be using these, since their output goes straight to stdout, which doesn't allow redirection. So this patch updates the ARI to detect any such use. gdb/ChangeLog: * contrib/ari/gdb_ari.sh: Add detection of printf_vma and sprintf_vma.

This patch moves safe_strerror from the gdb/{posix,mingw}-hdep.c files to the respective common/{posix,mingw}-strerror.c files. This is a preparation for the next patch, which shares a common code (to disable address space randomization when creating a new inferior).

This includes changes made in Fedora's gdb packaging[1], Doug's robustness patch[2] from before gdb-add-index was dropped, some corrections, and some more changes Doug accumulated in the meantime[3].

2013-05-30add the cleanup checkerTom Tromey2-1/+366
This patch adds the cleanup checker. This is a Python plugin for GCC that checks some rules for cleanup handling. In particular it tries to notice when cleanups are left dangling at the end of a function. It does this by applying a few simple rules. First, it understands that a function whose return type is "struct cleanup *" is a "cleanup constructor". Such functions are expected to return the first cleanup that they make. Then, it has the notion of a "master cleanup". The checker keeps a stack of all cleanups made in a basic block. The first element is pushed on the stack is the master cleanup -- the one that must later be passed to either do_cleanups or discard_cleanups. It is not perfect -- some constructs confuse it. So, part of this series rewrites some code in gdb so that it is analyzable. I'll note these spots and you can decide whether or not this is a good idea. This patch also changes gcc-with-excheck to give it options. Now you must use either -Xc (for the cleanup checker) or -Xx (for the exception checker). * contrib/cleanup_check.py: New file. * contrib/gcc-with-excheck: Add option parsing.
