--- Comment #1 from David Blaikie <dblaikie at gmail dot com> --- Oh - and if we can confirm the direction you're going with this (if the decision is that the prologue should start, like Clang, at the opening '{' always, for example) I'll go ahead and update the GDB test suite to either be agnostic or to KFAIL those tests under GDB, referencing this bug.
