Author: dim Date: Thu Aug 6 19:24:17 2020 New Revision: 363981 URL: https://svnweb.freebsd.org/changeset/base/363981 Log: Reapply r362235 (by kp): llvm: Default to -mno-relax on RISC-V Compiling on a RISC-V system fails with 'relocation R_RISCV_ALIGN requires unimplemented linker relaxation; recompile with -mno-relax'. Our default linker (ld.lld) doesn't support relaxation, so default to no-relax so we don't generate object files the linker can't handle.
