--- Comment #33 from Martin Jambor <jamborm at gcc dot gnu.org> ---
The patch from comment #32 passes LTO-bootstrap and profiled-LTO-bootstrap on
x86_64-linux.  I have asked Honza to look at it and comment, especially on the
decision to put the return VR into clone_info despite that these often do not
describe a clone.
