--- Comment #2 from Andrew Fish <afish at apple.com> ---
For gas we implemented .subsections_via_symbols as a CPP macro and defined it
per toolchain. Our goal is to share the same edk2 nasm file for VC++, GCC,
clang, and macOS Xcode builds. We run the C pre-processor and a trim tool on
the .nasm file prior to invoking nasm, so anything we can put in a CPP macro
will work. I'd like it to error out on unsupported versions and platforms. We
can configure the feature via CPP macro. 

We don't require .no_dead_strip as you can just follow the naming rules for
.subsections_via_symbols and it is not required. I can track down how it works
if you would like to add it?
