Overview

A GNU inline-assembly statement in its only accepted (degenerate) form (DESIGN R7): __asm__ with optional volatile qualifiers and an empty template, e.g. __asm__ volatile("" ::: "memory");. The parser has already verified the template is empty and no real operand appears, so nothing is carried but the keyword token; it lowers to no code at all — rubycc never reorders, so a memory-clobber barrier is a natural no-op.
