[PATCH] D146059: [SystemZ] Allow fp/int casting into inline assembly operands

[Ilya Leoshkevich via Phabricator via llvm-commits]

iii added inline comments.


================
Comment at: llvm/test/CodeGen/SystemZ/inline-asm-fp-int-casting.ll:43
+  %cc_dep1 = load i128, ptr %0, align 8
+  %1 = tail call i128 asm sideeffect "", "=f,0"(i128 %cc_dep1)
+  store i128 %1, ptr %agg.result, align 8
----------------
Did this work for you in GCC? I tried:

    __int128 foo(__int128 bar) {
        asm("" : "+f" (bar));
        return bar;
    }

and got:

    error: inconsistent operand constraints in an ‘asm’

I wanted to give it a try, because I would expect `ld`/`std` here, like for long double.
