[llvm-commits] [PATCH] Inline assembly dialect attribute for IR

[Chad Rosier]

All,
Following up on my previous post about MS-style inline assembly [1], the attached patches add support for a new inline assembly dialect function attribute.  This new attribute is intended to be used by the backend to determine how the inline asm string should be parsed/printed.  The llvm patch adds the attdialect and inteldialect attributes and also adds a test case to ensure the IR is correctly parsed, but there is no functional change at this time.  The clang patch adds the attdialect attribute to GNU-style inline assembly statements with a test case.  There was some discussion of adding an asmdialect attribute that accepted an optional argument (e.g., asmdialect "intel", asmdialect "att"), but this looks to add a great deal of complexity to the attribute handling with minimal benefit.
