comparison backend.h @ 563:c8fefa140c80

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Moved some generic stuff from backend.h gen_arm.h and gen_arm.c into gen.h and gen.c. Added a couple fields to cpu_options so that gen_mem_fun can be made guest CPU generic
