* mold gained a new linker flag --separate-debug-info to bundle debug info
sections into a separate file instead of putting them into a main output file.
You can optionally specify a filename in the form of
--separate-debug-info=<filename>. By default, a debug info file is created in
the same directory as the main output file with the .dbg extension. mold embeds
the debug file's filename into the main output file so that gdb can
automatically follow the link to find debug info when debugging the main output
file.
* The main objective of this flag is to speed up the mold linker even more. By
default, mold creates a separate debug file in the background after creating a
main output file, so that you can start running the executable as soon as
possible while mold is still working on linking its debug info sections. For
example, linking clang with debug info normally takes ~1.70s on a Threadripper
7980X machine, while it takes only ~0.52s with --separate-debug-info. Shaving
off a full second in quick edit-rebuild-run cycles should improve programmers'
productivity. If you do not want mold to work in the background, pass the
--no-detach option. (596ffa9)
* mold now supports the --no-allow-shlib-undefined flag. If the option is given,
mold checks if all undefined symbols are resolved not only for input object
files but also for shared libraries passed to the linker. To use the feature,
you need to pass all shared libraries, including transitively dependent ones, to
the linker so that the linker can resolve all symbols that are available at
runtime. (3001f02)
* mold gained the --dynamic-list-data flag for the sake of compatibility with GNU
ld. If the flag is given, all data symbols are exported as dynamic symbols.

* [x86-64] -z x86-64-v2, -z x86-64-v3, -z x86-64-v4 flags are supported. (5606087)
* [x86-64] Recent x86-64 processors support Intel CET to protect control flow
integrity. When the feature is enabled, the instruction that is executed

%description
|
|
mold is a faster drop-in replacement for existing Unix linkers.
|
|
It is several times faster than LLVM lld linker, the second-fastest
|
|
open-source linker.
|
|
mold is created for increasing developer productivity by reducing
|
|
build time especially in rapid debug-edit-rebuild cycles.
