示例1:
static void
gen_shrink_wrap_conditions (gimple bi_call, vec<gimple> conds,
unsigned int *nconds)
{
gimple call;
tree fn;
enum built_in_function fnc;
gcc_assert (nconds && conds.exists ());
gcc_assert (conds.length () == 0);
gcc_assert (is_gimple_call (bi_call));
call = bi_call;
fn = gimple_call_fndecl (call);
gcc_assert (fn && DECL_BUILT_IN (fn));
fnc = DECL_FUNCTION_CODE (fn);
*nconds = 0;
if (fnc == BUILT_IN_POW)
gen_conditions_for_pow (call, conds, nconds);
else
{
tree arg;
inp_domain domain = get_no_error_domain (fnc);
*nconds = 0;
arg = gimple_call_arg (bi_call, 0);
gen_conditions_for_domain (arg, domain, conds, nconds);
}
return;
