I'm trying to put together a Micro Conference for Linux Plumbers
conference focused on "make LLVM slightly less shitty."  Do you all
plan on attending the conference? Would it be worthwhile to hold a
session focused on discussing this (LTO and memory models) be
worthwhile?
I'd love to have a session about compilers and memory ordering with both
GCC and CLANG in attendance.

We need a solution for dependent-loads and control-dependencies for both
toolchains.
What Peter said!  ;-)
