# The bundled build system for tbb tries to strip all Werror from the
# CFLAGS/CXXFLAGS when not building in strict mode (mold doesn't use strict
# mode). We don't want that because it causes the "Werror=format-security"
# option to become "=format-security" and break the build. (similar to a patch
# in the Fedora tbb package)
Patch0:		tbb-strip-werror.patch

# Pass the system's CXXFLAGS and CFLAGS to the bundled libraries to ensure they
# are built with all the Fedora hardening flags and with PIE (otherwise the
# linker errors linking non-PIE code with PIE code).
Patch1:		bundled_lib_system_flags.patch

# Fix for failed assertion on aarch64
Patch2:		0001-Fix-out-of-bounds-error-on-aarch64-with-_GLIBCXX_ASS.patch

# mold can currently produce native binaries for these architectures only

%description
mold is a multi-threaded, high-performance linker that is several times faster
than the industry-standard ones, namely, GNU ld, GNU gold or LLVM lld. It is
developed as a drop-in replacement for these linkers and command-line compatible
with them with a few exceptions.
