- Update to version 2.4.0
* mold gained the --spare-program-headers=<number> option, which adds a specified
number of spare entries at the end of the program header. The option aims to
make post-processing tools to add program header entries very easily. Note that
sorting program header entries after adding new ones may be necessary to meet
the constraints of the ELF file format. For details, see the elf(5) man page.

* mold's -z rewrite-endbr option rewrites superflous endbr64 instructions with nop
as a countermeasure against control-flow highjacking attacks. Previously, this
worked exclusively with object files compiled with -ffunction-sections,
requiring each function to be compiled into a separate section. Starting from
this release, -z rewrite-endbr works on object files compiled without it. In
other words, mold is now capable of rewriting endbr64 instructions even if the
instruction is not at the beginning of a section. (3cb8a52)
* Previously, mold couldn't handle object files containing multiple .eh_frame
sections. The .eh_frame is a section containing data for exception handling.
Usually, an object file contains only one .eh_frame which describes how to
handle exceptions for all text sections in the same file. However, on rare
conditions, it seems ld -r creates an object file containing multiple .eh_frame
sections. mold is now able to handle such object files. (f4c5a8a)
* mold -run <command> is an easy way to run the given command with a virtual
environment in which the ld command is replaced with mold. The feature is
implemented using LD_PRELOAD to hook fork(2)-family functions. Before this
release, some invocations of ld were not intercepted correctly because we missed
the posix_spawnp(2) function. Now, the function is intercepted just like other
fork(2)-family functions. (3fd1cec)
* mold used to produce a non-working executable on a rare occasion when all
thread-local variables lacked an initial value and the read-only data required
alignment equal to or greater than the page size. This bug has been resolved.
