comparison gen/runtime.cpp @ 1300:329e45865d84

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add 'nounwind' attribute to the relevant runtime functions, and use it when deciding whether or not to generate an invoke instead of a call.
