Hi, The LLVM lang ref (http://llvm.org/docs/LangRef.html#i_bitcast) notes that bitcast of vectors to vectors is OK, provided the vectors are of the same size. In attempting this on large vector types (e.g. 16xi64 -> 16xf64), I get assertions related to Extended Value Types when attempting to perform code generation, but no errors at the BC level. Is it sim...

Hi, Based on LLVM lang spec (http://llvm.org/docs/LangRef.html#i_bitcast<http://www.google.com/url?sa=D&q=http://llvm.org/docs/LangRef.html%23i_bitcast&usg=AFQjCNFsBtV4Cr8zpL5UpgoIASRDFvcdSw>) notes I have understood ,that bitcast of vectors to vectors is OK,only if provided the vectors are of the same size.Is it possible to convert a vectors from differen...

Hello, LLVM team! I faced a problem with passing structures by value on Windows (both x86 and x64). I tried to write simple { i32 i32 } Vector2D addition using IR builder (signature is Vector2D add(Vector2D a, Vector2D b)). x86 version worked fine, but on x64 function returned incorrect value. Some research showed, that { i16 i16 } addition also fails on x86, so I guess the problem is in passing

In the documentation at [http://llvm.org/docs/LangRef.html], we have the section [#aggregateconstants] telling us that the aggregate constants are: * Structure constants * Array constants * Vector constants * Zeroinitialization However, in [#constantexprs] we have a bitcast(CST, TYPE) operator with the documentation (emphasis by me): Convert a constant, CST, to another TYPE. The size of
