Note I wonder why the operand scanner doesn't ICE here ... Indeed we have ;; Function erfcx_r4 (__error_function_MOD_erfcx_r4, funcdef_no=0, decl_uid=4215, cgraph_uid=1, symbol_order=0) __attribute__((fn spec (". r "))) real(kind=4) erfcx_r4 (real(kind=4) & restrict x) { real(kind=4) __result_erfcx_r4(address-taken); static integer(kind=4) jint(address-taken) = 2; real(kind=4) (*<T66a>) (real(kind=4) & restrict) erfcx_r4.0_1; real(kind=4) _6; <bb 2> : erfcx_r4.0_1 = erfcx_r4; *erfcx_r4.0_1 ={v} {CLOBBER}; calerf_r4 (x_4(D), &__result_erfcx_r4(address-taken), &jint(address-taken)); _6 = __result_erfcx_r4(address-taken); and .original already has __attribute__((fn spec (". r "))) real(kind=4) erfcx_r4 (real(kind=4) & restrict x) { static integer(kind=4) jint(address-taken) = 2; real(kind=4) __result_erfcx_r4(address-taken); erfcx_r4 = {CLOBBER}; calerf_r4 ((real(kind=4) *) x, &__result_erfcx_r4(address-taken), &jint(address-taken)); return __result_erfcx_r4(address-taken); }
