| These are in-progress notes for the upcoming LLVM 8.0.0 release. |

| |
| Introduction |
| ============ |
| |
| This document contains the release notes for the lld linker, release 8.0.0. |
| Here we describe the status of lld, including major improvements |
| from the previous release. All lld releases may be downloaded |
| from the `LLVM releases web site <https://llvm.org/releases/>`_. |
| |
| Non-comprehensive list of changes in this release |
| ================================================= |
| |
| ELF Improvements |
| ---------------- |
| |
| * lld now supports RISC-V. (`r339364 |
| <https://reviews.llvm.org/rL339364>`_) |
| |
| * Default image base address has changed from 65536 to 2 MiB for i386 |
| and 4 MiB for AArch64 to make lld-generated executables work better |
| with automatic superpage promotion. FreeBSD can promote contiguous |
| non-superpages to a superpage if they are aligned to the superpage |
| size. (`r342746 <https://reviews.llvm.org/rL342746>`_) |
| |
| * lld/Hexagon can now link Linux kernel and musl libc for Qualcomm |
| Hexagon ISA. |
| |
| * The following flags have been added: ``-z interpose``, ``-z global`` |
| |
| COFF Improvements |
| ----------------- |
| |
| * PDB GUID is set to hash of PDB contents instead to a random byte |
| sequence for build reproducibility. |
| |
| * The following flags have been added: ``/force:multiple`` |
| |
| * lld now can link against import libraries produced by GNU tools. |
| |
| * lld can create thunks for ARM, to allow linking images over 16 MB. |
| |
| MinGW Improvements |
| ------------------ |
| |
| * lld can now automatically import data variables from DLLs without the |
| use of the dllimport attribute. |
| |
| * lld can now use existing normal MinGW sysroots with import libraries and |
| CRT startup object files for GNU binutils. lld can handle most object |
| files produced by GCC, and thus works as a drop-in replacement for |
| ld.bfd in such environments. |
| |
| MachO Improvements |
| ------------------ |
| |
| * Item 1. |
