riscv-lld

This repository contains the RISC-V port of lld (the LLVM linker).

Status

• Can link static ELF executables
• Can link dynamic ELF executables (PIE) and shared libraries
• Thread-local storage (TLS) support
• Can link RISC-V's Linux kernel
• Pass most of GCC testsuite modulo error message differences
• Unit tests

Patches are submitted for review on LLVM phabricator.

This repository will be regularly rebased onto lld master.

How to build

$ git clone https://github.com/llvm-mirror/llvm && cd llvm
$ git checkout 1435ef31d8556e5ab90a6ba8c4947da858625d79
$ git clone https://github.com/riscv/riscv-lld tools/lld
$ mkdir build && cd build
$ cmake -DCMAKE_BUILD_TYPE=Release \
        -DLLVM_ENABLE_PROJECTS=lld \
        -DTARGETS_TO_BUILD= \
        -DEXPERIMENTAL_TARGETS_TO_BUILD=RISCV \
        ..
$ make lld

Usage

You may invoke ld.lld directly or replace ld in the toolchain path with ld.lld:

$ cp bin/ld.lld ${path_to_toolchain}/bin/ld.lld
$ ln -sf ${path_to_toolchain}/bin/{ld.lld,ld}
