* mold supports a feature called Identical Code Folding, or ICF. As the name
suggests, ICF finds identical functions and merges them to reduce the size of an
output file. This is especially effective for template-heavy C++ programs since
templates tend to be instantiated to the same machine code for different types.
For example, std::vector<int> is likely to be instantiated to the same code as
std::vector<unsigned>. We've made an improvement to our ICF algorithm so that
the --icf feature is ~50% faster than the previous version. (fa8e95a)
* The -z rodynamic option is now supported for compatibility with LLVM lld. With
the option, mold places the .dynamic section into a read-only segment. (9a233df)
* Previously, mold behaved differently compared to other linkers if both -z defs
and --undefined=ignore-in-object-files were given (#1270). Now, they override
each other so that the mold's behavior is compatible with others. (8cd85aa)
* Previously, --dependency-file mistakenly recorded response files as dependencies
(#1258). This bug has been fixed. (4281f45)
* There was a bug that mold corrupted debug info section contents when the
--relocatable option was given (#1265). This issue has been fixed. (08b0a16)
* [PPC64] The R_PPC64_TPREL16_LO_DS relocation type is supported. (a8cd2e8)
* [ARM64, PPC64, LoongArch] mold 2.31.0 or earlier may have failed with an
assertion failure when creating a large output file (#1224). This issue has been
resolved. (c7c8583)

%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.
