Dear All, I think adding metadata and expecting transforms to repect it is a bad idea. It is just too easy for someone who does not know about the metadata to add a transform that ignores it. As for SAFECode, I think we have one of several options for handling load-widening. The most obvious one is to have a pass that just boosts the allocation size of any alloca with an align 16 attribute;

Any other suggestion? --kcc -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20111228/5564a63b/attachment.html>
