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/>`_.
+lld is a high-performance linker that supports ELF (Unix), COFF (Windows),
+Mach-O (macOS), MinGW and WebAssembly. lld is command-line-compatible with
+GNU linkers and Microsoft link.exe and is significantly faster than the
+system default linkers.
+
+nlld 8.0.0 has lots of feature improvements and bug fixes.

+* lld now attempts to place a ``.note`` segment in the first page of a
+ generated file, so that you can find some important information

+ file is truncated by ulimit.

* lld/Hexagon can now link Linux kernel and musl libc for Qualcomm
Hexagon ISA.
* Initial MSP430 ISA support has landed.
-* The following flags have been added: ``-z interpose``, ``-z global``
-
* lld now uses the ``sigrie`` instruction as a trap instruction for
MIPS targets.
+* lld now creates a TLS segment for AArch64 with a slightly larger
+ alignment requirement, so that the loader makes a few bytes room
+ before each TLS segment at runtime. The aim of this change is to
+ make room to accomodate nonstandard Android TLS slots while keeping
+ the compatibility with the standard AArch64 ABI.
