Log Message:
mold: update to 1.10.0.
New features:
- 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.
- [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.
- [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.
Bug fixes and compatibility improvements:
- 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.
- 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.
- mold 1.9.0 might crash with SIGSEGV if --emit-relocs is used with object
files containing debug info. That bug has been fixed.
