--- Comment #25 from Anitha Boyapati <anitha.boyapati at atmel dot com> 2011-06-15 02:37:59 UTC --- (In reply to comment #24) > The testcase at the head of the PR is now fixed. > > For the 4.6 branch, this required also backporting > (Assuming that backporting implies the emission of DWARF2 CFI) Is it not possible to drop DWARF2 CFI feature (which is optional) and still make 4.6x build successful? It is quite possible that some target might want to do this. If the intention is to make CFI mandatory, then internals document should be updated as well.
