diff gen/tollvm.h @ 1210:3d4581761b4c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add some alignment info where LLVM might otherwise be more pessimistic. In particular, %.nest_arg is always aligned even though it's bitcast from i8*. Pointers in vtables are also guaranteed to be stored at aligned addresses.
