Announced on https://lists.llvm.org/pipermail/llvm-dev/2020-May/141416.html For many options, we have to support either one or two dash to be compatible with GNU ld. For newer and lld specific options, we can enforce strict double dashes. Affected options: * --thinlto-* * --lto-* * --shuffle-sections= This patch does not change `-plugin-opt=*` because clang driver passes `-plugin-opt=*` and I don't intend to cause churn. In 2000, GNU ld tried something similar with --omagic https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e4897a3288f37d5f69e8acd256a6e83e607fe8d8 Reviewed By: tejohnson, psmith Differential Revision: https://reviews.llvm.org/D79371
