--- Comment #2 from Matt Hargett <matt at use dot net> 2012-12-05 00:56:56 UTC --- We have a large C++ application that was working with LTO in google/gcc-4_6, and now we're running into issues on google/gcc-4_7. We saw performance gains and binary size decreases with LTO that were extremely useful. Understandably, we're concerned about using LTO as all with the newer toolchain if bootstrap-lto doesn't work. Are there other patches from trunk not yet backported into the 4_7 branch that make merging the other LTO fixes difficult? Anything you can do to restore the functionality that worked in previous google branches is greatly appreciated. Thanks!
