David Binderman <dcb314 at hotmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at redhat dot com --- Comment #5 from David Binderman <dcb314 at hotmail dot com> --- I am struggling to make further progress with this one. Commit cd676dfa57e643a4f7d8445e6ebad0f21cf3fd84 looks suspicious, since it is the only one that changes anything in compiler source code file gimple-ssa-store-merging.c in the good .. bad range. Jakub, your best advice sought, please.
