[cfe-users] How do I make CMake use LLD
Hi, Keeping the system linker as GNU ld, how do I make CMake use LLD at configure time? alias ld='lld' does not seem to work. ___ cfe-users mailing list cfe-users@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
Re: [cfe-users] How do I make CMake use LLD
I was just setting the flag for the C++ compiler wrapper, but doing the same for the C compiler seems to work (on ppc64le linking with LLD fails though).
