...mplex a special aggregate - Specified literal syntax - Added special index values "real" and "imag" for insertvalue/extractvalue of complex - Added czip intrinsic to create vector of complex from vectors of real/imaginary - Added extractreal and extractimag intrinsics for vectors of complex - Added masked vector intrinsics Abstract -------- Several vendors and individuals have proposed first-class complex support in LLVM. Goals of this proposal include better optimization, diagnostics and general user experience. Introduction and Motivation -...

...n questions - A cunzip intrinsic would need to work at the IR level, returning two separate SSA values. How can this be done? The example given was a Hexagon-specific intrinsic that doesn't appear to make use of the two destinations at the IR level. - Are separate extratreal/extractimag intrinsics sufficient for targets that support such operations (e.g. NEON's VUZP)? - The proposal allows bitcasts of vector of complex, even though bitcasts of aggregates in general are disallowed. Is this special case reasonable? - If we allow such bitcasts, is czip necessary, o...
