Sam Clegg 37f422f4ac [WebAssembly] Use GeneralDynamic TLS for exception handling builtins.
These global TLS symbols are shared across all shared libraries and
therefor should not be assumed to be local to the current module.

Also add new error in the linker when TLS relocations are used against
undefined symbols.  TLS relocations are offsets into the current modules
tls data segment, and don't make sense for undefined symbols which are
modeled as global imports.

LLVM Linker (lld)

This directory and its subdirectories contain source code for the LLVM Linker, a modular cross platform linker which is built as part of the LLVM compiler infrastructure project.

lld is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt.

Benchmarking

In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.

It is hosted at https://s3-us-west-2.amazonaws.com/linker-tests/lld-speed-test.tar.xz
