* Big-endian ARM64 is now supported. ARM64 is a bi-endian processor, meaning that
the processor can run in either little- or big-endian mode. Even though
little-endian is the de facto standard, the ARM64 processor-specific ABI defines
its big-endian variant, and the ARM toolchain supports it. Now we support it
too. (882e7eb)
* Big-endian SH4 is now supported. SH4 has become a minor CPU nowadays, and its
big-endian variant is even more so, but some SHARP scientific calculators still
use SH4 processors in big-endian mode. (0cb9fc6)
* mold attempts to overwrite an existing file if a specified output file already
exists because reusing an existing file is much faster than creating a fresh
file and writing to it on Linux. If an existing file is currently running,
open(2) for that file fails with ETXTBSY. When that happens, mold falls back to
creating a new file. The problem here is that Linux kernel version 6.11 changed
that well-known behavior of open(2), and it now allows user programs to
overwrite a running executable. That caused a very mysterious issue for programs
that rebuild themselves during the build, such as gcc or ninja (#1361). Even
though the kernel's change has been reverted (torvalds/linux@3b83203), we need
to make adjustments to mold for that particular version of the Linux kernel. So,
if mold detects that it is running on Linux 6.11, it no longer tries to reuse an
existing output file. (8e4f7b5)
* On rare occasions, mold could fail with a "ConcurrentMap is full" error. Now the
issue has been resolved. (e56b649)
* Even if a user choose not to use mimalloc memory allocator (i.e. built mold with
-DMOLD_USE_MIMALLOC=0), mold was still being built with mimalloc. This issue has
been resolved. (ffd10dd)
* [s390x] s390x uses nonstandard 8-byte entries for the .hash section. Previously,
mold created 4-byte entries for .hash, which caused mold-generated executables
to crash on startup if they were built with -Wl,--hash-style=sysv. Now, mold
generates a psABI-compliant .hash section. (e2e1146)

%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.
