--- Comment #3 from Oleg Endo <olegendo at gcc dot gnu.org> --- (In reply to Richard Biener from comment #2) > D is not part of FSF GCC so I am inclined to close as invalid. If there's a bug that shows up with D but doesn't show up with non-D, and the bug can be identified as an SH backend bug and it's not too complex, then we can fix it. Otherwise I guess we'd have to pass the ball to the debian maintainers of their version of GCC (they also apply a bunch of patches, a vanilla GCC doesn't even build out of the box on SH4 debian). Anyway, please leave this PR open for now.
