mold 1.2.1 is a new release of the high-speed linker. This release contains the following bug fixes.

Bug fixes and compatibility improvements

• Various bugs in --gdb-index have been fixed.
• mold now recognizes --thinlto-cache-dir and --thinlto-cache-policy for the sake of compatibility with LLVM lld. (7ebd071273691a5cc095203f6542b2b13ec6642c)
• mold can now handle TLS common symbols. It looks like GCC sometimes creates such symbol for a thread-local variable. (cf850f8993210185e57c329ce14a361b7e51cbe0)
• In some edge cases, mold created a non-versioned symbol and a versioned one for the same symbol, even though if one symbol is versioned, all symbols of the same name must be versioned. This bug has been fixed. (8298c0ad16a4ab9cf95efe4ada43bbba9f33941d)
• mold used to write a PLT address of a symbol instead of its address to .symtab. This bug has been fixed. (e088db72e006e8f1bcbc7c9561a3e22777cd33ff)
• mold can now handle an input file with more than 2¹⁹ symbols. (f1f2d40469a3a501c573b1181e0e4362c030a9bf)
• /usr/local/libexec/mold/ld is now installed as a relative symlink instead of an absolute symlink. (5803c3c200f301adc3abdb66df16d3d669712d70)
