Here's a prototype for i386 only, which stands up to light testing.
I'd rather post this tonight rather than wait until tomorrow when I
can write more proper dejagnu tests.
I've tested the intermedate patches via config-list.mk, so despite
mucking around with vec.h vs target.h, all targets still compile.
That said, quite a bit of cleanup in expand_asm_stmt was required
in order to make the target hook not be completely unintelligable,
so depsite full regression testing on x86_64 and ppc64, I could
well have broken something.
r~
void bar(void);
#define DO1(C) \
int s##C(void) { int r; asm("" : "=@cc"#C(r)); return r; } \
int j##C(void) { int r; asm("" : "=@cc"#C(r)); if (!r) bar(); }
#define DO2(C) DO1(C) DO1(n##C)
DO2(a)
DO2(b)
DO2(c)
DO2(e)
DO2(g)
DO2(l)
DO2(o)
DO2(p)
DO2(s)
DO2(z)
DO2(ae)
DO2(be)
DO2(ge)
DO2(le)
