Mold 2.35 Released With Big Endian ARM64 Support
Rui Ueyama announced the release today of Mold 2.35 as the latest iteration of this high speed linker alternative to the linkers available from the GCC and LLVM toolchain projects.
Somewhat related to Rui Ueyama where he recently outlined some Linux kernel performance bottlenecks holding up the Mold linker and one of them being that it's slower writing to a fresh file than an existing file, in Mold 2.35 he's had to workaround some buggy behavior in this area with Linux 6.11. 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. So, if mold detects that it is running on Linux 6.11, it no longer tries to reuse an existing output file."
