Hmm, the comment in c-typeck.c:
/* Build an asm-expr, whose components are a STRING, some OUTPUTS,
   some INPUTS, and some CLOBBERS.  The latter three may be NULL.
   SIMPLE indicates whether there was anything at all after the
   string in the asm expression -- asm("blah") and asm("blah" : )
   are subtly different.  We use a ASM_EXPR node to represent this.  */

so maybe this is invalid after all.
