...gnment) to those expected by the callee. It seems LLVM 3.0 implements value-preserving alias, while previous LLVM versions implemented (perhaps by accident) bit-preserving alias. It's worth noting that in many cases both kinds of alias produce the same results... for example, in OpenCL: static uint2 __ SH1I422 ( uint2 foo, uint2 ) { ... } extern __attribute__((overloadable, weak, alias("__SH1I422"))) uint2 shuffle(uint2, uint2); extern __attribute__((overloadable, weak, alias("__SH1I422"))) int2 shuffle(int2, uint2); Both value-preserving and bit-preserving alias do the sa...

Hi LLVM, I would like to compile OpenCL kernel for a specific AMD GPU target. Is it possible with the current clang/LLVM? I started by using `clang -x cl` but it looks like at least some OpenCL specific headers are missing (e.g. uint2 is not recognized as a type). Any links to documentation / tutorials very welcome. Thanks. - Paweł -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20150929/d2aa59c2/attachment.html>
