* mold now officially supports the --print-dependencies option to print out
dependency information between input files. Here is a truncated example output
when linking mold itself with the option. There are many use cases of the
option; for example, if you want to eliminate the dependency to some library
from your program, you can use this option to find out all the functions that
use the library's function to fix them. (6fd47db)
* [x86-64][s390x] mold now optimizes thread-local variable accesses in shared
libraries if the library is linked with -z nodlopen. If your shared library is
not intended to be used via dlopen(2) and your library frequently accesses
thread-local variables, you might want to pass that option when linking your
library. (25d02bb, f32ce33)
* [arm64] mold is now able to optimize GOT load by rewriting an ADDR+LDR
instruction pair with an ADDR+ADD if the loaded GOT value is known at link-time.
(f2311b1)
* mold 1.9.0 was up to 10% slower than 1.8.0 on some multicore machines. We fixed
the performance regression and made it even faster than 1.8.0. (7132822)
* Previously, mold failed to report an undefined symbol error if there's a weak
undefined symbol of the same name. That bug resulted in producing a non-working
executable instead of reporting a link failure. Now, mold correctly reports such
link errors. (8936194)
* mold 1.9.0 might crash with SIGSEGV if --emit-relocs is used with object files
containing debug info. That bug has been fixed. (e17d7da)

%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.
