_Does_ basic asm as currently implemented have a memory clobber? If not,
it seems we can just remove basic asm completely and everything would
still work the same!
You'd have to dig into the various optimizers -- I know that it has a
memory use

Hi,
The x86-64 psABI has been updated to revision 248. Main changes are
1. Support Intel MPX.
2. Add a chapter for linker optimization.
3. Add 2 new relocations, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX.
MPX supported has been checked into GCC 5 and ld in binutils 2.25.
Linker optimization
For libmpx the reason is that MPX ISA doesn't support x32. I.e. MPX
instructions can't use 32bit bounds in 64bit mode.
