diff gen/tollvm.cpp @ 1480:b3ba2c6ff038

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use `llvm.memset` instead of `_d_array_init_i1` and `_d_array_init_i8`. This exposes what's happening to LLVM, and memset is probably faster than the runtime functions we were using anyway.
