------- Comment #2 from hubicka at gcc dot gnu dot org 2009-12-11 11:37 ------- ipa nothrow is hidden in ipa-pure-const (that should be renamed eventually). However issue here is that at IPA stage we should not touch function bodies, so we should not do these updates. This is why fixup pass exists to resolve these cases after we get into local compilation.
This however seems like LTO is getting something wrong, we do make throw flags to disappear at IPA for quite some time. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41835
