* PPC64LE and SPARC64 are now supported as new targets. They haven't yet been as
well tested as other targets, but they are already able to link mold itself on
these platforms. (Note that PPC64LE is very unlikely to work on the most recent
POWER10 machines as we didn't have a chance to test it due to a limited
availability (POWER10 was released in 2021). If you can support us on this
matter, please contact us. We also accept donations, so please consider
supporting our project!)
* RV32BE and RV64BE (32-bit and 64-bit big-endian RISC-V) are now supported as
experimental targets. RISC-V is usually little-endian, but there exists a
big-endian RISC-V as an extension. You can make gcc to emit code for big-endian
RISC-V by passing -mbig-endian. mold can now link object files generated with
that option.
* --compress-debug-sections=zstd is now supported. This is an option to compress
debug info embedded to an output file with Zstandard compression algorithm.
Compared to the existing --compress-debug-sections=zlib, zstd is faster and
gives a higher compression ratio. You probably can't start using zstd
compression today though, because other tools such as gdb may not be able to
read zstd-compressed debug info yet. But adding this option early makes mold
future-proof. (ede7a5a)
* mold no longer aligns loadable segments to page boundaries to reduce output file
size. Previously, we allocated holes between loadable segments. The saving by
this change is most visible for small programs. For example, a "hello world"
program used to be ~18 KiB on x86-64. It's now 7.2 KiB. (2941d75)
* Bug fixes and compatibility improvements
* [RISCV] We optimized code so that the link speed for RISC-V is now comparable to
the other targets. As an example, linking mold itself (~150 MiB in size) for
RV64 used to take ~45 seconds on a simulated 16-core machine. It now takes only
~0.25 seconds. (3ab5489)
* mold used to create more than one .rodata section under a certain condition.

%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.
