...rnal developers, I would like to propose a small IR extension. Specifically, I would like to add a function attribute to inline asm calls that indicates the syntax in which the asm is written. E.g., call void asm sideeffect "nop\n\t", "~{dirflag},~{fpsr},~{flags}"() nounwind iasyntaxatt Notice the addition of the iasyntaxatt keyword. This is used by the AsmPrinter to determine the correct asm variant. I've implemented this change and would be happy to send it to the commits list for review. However, the backend doesn't currently use this information so I don't thin...

I'm not familiar with how IR metadata works, but instead of having specific syntax attributes (iasyntaxatt), it would be cleaner to have a generic asmsyntax attribute that could take att/intel values. I don't think metadata would be the right approach as it would be rather heavy handed considering were only storing a bit or two of information. An attribute is the right way to go, so this is really...
