Subject: Configure clang with LLVM_ENABLE_LLD=ON
X-Git-Tag: debian/2018.11-4~1
X-Git-Url: http://rtime.felk.cvut.cz/gitweb/hercules2020/hercules-compiler.git/commitdiff_plain/a59af5800802346ee0f30ab2f6f170406b9f797f

Configure clang with LLVM_ENABLE_LLD=ON

This enables the use of LLVM linker rather than using GNU linker.
With LLVM linker it is possible to use the compiler as a
cross-compiler e.g. by using --target=aarch64 switch.
