Martin Liška 96860f114e - 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.

%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.
