Normalize includes to use common/
This changes all includes to use the form "common/filename.h" rather than just "filename.h".

Update copyright year range in all GDB files.
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. |

Move mkdir_recursive to common/filestuff.c
This moves mkdir_recursive from dwarf-index-cache.c to common/filestuff.c, and also changes it to return a boolean that says whether or not it worked. gdb/ChangeLog 2018-10-27 Tom Tromey <tom@tromey.com> * unittests/mkdir-recursive-selftests.c: New file. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/mkdir-recursive-selftests.c. * dwarf-index-cache.c (mkdir_recursive): Move to common/filestuff.c. (index_cache::store): Check return value of mkdir_recursive. (create_dir_and_check, test_mkdir_recursive): Move to new file. (_initialize_index_cache): Don't register test. * common/filestuff.h (mkdir_recursive): Declare. * common/filestuff.c (mkdir_recursive): Move from dwarf-index-cache.c. Return bool. |

Fix some gettext ARI warnings
ARI produces this warning for the lines touched in this patch: warning: gettext: All messages should be marked up with _. However, in these cases, the message is not translatable (they are syscall names). Adding an extra set of parentheses silences the warning. gdb/ChangeLog: * common/scoped_mmap.c (mmap_file): Silence ARI warning. * dwarf-index-cache.c (create_dir_and_check): Likewise. (test_mkdir_recursive): Likewise. * dwarf-index-write.c (write_psymtabs_to_index): Likewise. |

Add DWARF index cache
New in v3: - Remove things related to the dwarf-5 format. - Fix compilation on mingw (scoped_mmap.c). GDB can generate indexes for DWARF debug information, which, when integrated in the original binary, can speed up loading object files. This can be done using the gdb-add-index script or directly by the linker itself. However, not many people know about this. And even among those who do, because it requires additional steps, I don't know a lot of people who actually go through that trouble. To help make using the DWARF index more transparent, this patch introduces a DWARF index cache. When enabled, loading an index-less binary in GDB will automatically save an index file in ~/.cache/gdb. When loading that same object file again, the index file will be looked up and used to load the DWARF index. You therefore get the benefit of the DWARF index without having to do additional manual steps or modifying your build system. When an index section is already present in the file, GDB will prefer that one over looking up the cache. When doing my edit-compile-debug cycle, I often debug multiple times the same build, so the cache helps reducing the load time of the debug sessions after the first one. - The saved index file is exactly the same as the output of the "save gdb-index" command. It is therefore the exact same content that would be found in the .gdb_index or .debug_names section. We just leave it as a standalone file instead of merging it in the binary. - The cache is just a directory with files named after the object file's build-id. It is not possible to save/load the index for an object file without build-id in the cache. - The cache uses the gdb index format. The problem with the dwarf-5 format is that we can generate an addendum to the .debug_str section that you're supposed to integrate to the original binary. This complicates a little bit loading the data from the cached index files, so I would leave this for later. - The size taken up by ~/.cache/gdb is not limited. I was thinking we could add configurable limit (like ccache does), but that would come after. Also, maybe a command to flush the cache. - The cache is disabled by default. I think once it's been out there and tested for a while, it could be turned on by default, so that everybody can enjoy it. - The code was made to follow the XDG specification: if the XDG_CACHE_HOME environment variable, it is used, otherwise it falls back to ~/.cache/gdb. It is possible to change it using "set index-cache directory". On other OSes than GNU/Linux, ~/.cache may not be the best place to put such data. On macOS it should probably default to ~/Library/Caches/... On Windows, %LocalAppData%/... I don't intend to do this part, but further patches are welcome. - I think that we need to be careful that multiple instances of GDB don't interfere with each other (not far fetched at all if you run GDB in some automated script) and the cache is always coherent (either the file is not found, or it is found and entirely valid). Writing the file directly to its final location seems like a recipe for failure. One GDB could read a file in the index while it is being written by another GDB. To mitigate this, I made write_psymtabs_to_index write to temporary files and rename them once it's done. Two GDB instances writing the index for the same file should not step on each other's toes (the last file to be renamed will stay). A GDB looking up a file will only see a complete file or no file. Also, if GDB crashes while generating the index file, it will leave a work-in-progress file, but it won't be picked up by other instances looking up in the cache. gdb/ChangeLog: * common/pathstuff.h (get_standard_cache_dir): New. * common/pathstuff.c (get_standard_cache_dir): New. * build-id.h (build_id_to_string): New. * dwarf-index-common.h (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move to here. * dwarf-index-write.c (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move from there.

(save_gdb_index_command): Adjust call to write_psymtabs_to_index. * dwarf2read.h (dwarf2_per_objfile) <index_cache_res>: New field. * dwarf2read.c (dwz_file) <index_cache_res>: New field.
