[cfe-dev] Clang rejects inline assembly that has tied operands with different types

[Akira Hatanaka]

I changed this function recently (yesterday), but I think this error message is unrelated to the change I made. The piece of code that emits this error was committed originally in r70142.

I’m not sure whether this restriction should be relaxed to allow operands with different size or it’s the source program that has to be fixed. I couldn’t find anything in gcc’s documentation that says whether or not this is legal.
