* Uses xxHash hashing algorithm. A 8% ~ 14% speedup.
* Set endianity of multifile using -e, --multifile-endian.
* Set pointer size of multifile using -p, --multifile-pointer-size
* Process files in parallel using -j N --jobs N. The default is
processors / 2. Disabled when multifile is used.
* Prints abbrev or DIE offset for Unknown DWARF error messages.
* All testcases have been updated to work against the binutils 2.39.

%description
|
|
dwz optimizes DWARF debugging information contained in ELF shared
|
|
libraries and executables for size, by replacing DWARF information
|
|
representation with equivalent smaller representation where possible,
|
|
and by reducing the amount of duplication using techniques from the
|
|
DWARF standard appendix E - creating DW_TAG_partial_unit compilation
|
|
units (CUs) for duplicated information and using DW_TAG_imported_unit
|
|
to import it into each CU that needs it.
|
|
|
|
The tool handles DWARF 32-bit format debugging sections of versions
|
|
2, 3 and 4 and GNU extensions on top of those, though using DWARF 4
|
|
or worst case DWARF 3 is strongly recommended.
|
|
|
|
When not using the -m option (multifile mode), GDB CVS snapshot (soon to be
|
|
7.5) is sufficient, when using -m option, GDB from a git branch
|
|
http://sources.redhat.com/git/?p=archer.git;a=shortlog;h=refs/heads/archer-tromey-dwz-multifile
|
|
is needed.
