I was looking at "trunc" to downcast a signed integer, say sint32 to sint16, but it seems to handle unsigned integers only. How do you downcast a signed integer? P.S. This question is for my "Mapping High-Level Constructs to LLVM IR" document :-) -- Mikael -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.or...

Hello > I was looking at "trunc" to downcast a signed integer, say sint32 to sint16, > but it seems to handle unsigned integers only. No. In twos-complement notation (which LLVM assumes) there no difference between signed and unsigned truncation - you just throw out the spare sign bits and that's all. Please note that that the "numbers" in LLVM IR is neither sign...

Please change all longs to int, and never use them in the future :) They arent needed as on most platforms they are the same size. (which is the assumption made in the ogg code anyway) The reason for this is i will have vorbis support on playstation 2, but long is 64 bits, and they are excruciatingly slow. cheers Brett Paterson --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg
