    Basic heap profile support without -prof · cbeb99ef
    Simon Marlow authored
    Now that constructor info tables contain the name of the constructor,
    we can generate useful heap profiles without requiring the whole
    program and libraries to be compiled with -prof.  So now, "+RTS -hT"
    generates a heap profile for any program, dividing the profile by
    constructor.  It wouldn't be hard to add support for grouping
    constructors by module, or to restrict the profile to certain
    This means that for the first time we can get heap profiles for GHCi,
    which was previously impossible because the byte-code
    interpreter and linker don't work with -prof.
