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.
