Ping for this patch to always supply a mode to plus_constant:
http://gcc.gnu.org/ml/gcc-patches/2012-04/msg00892.htmlI've done a diff of the changes since the original test revision (which was r186448 FWIW) and there's only been one plus_constant- related change since then: Alan's rs6000 prologue/epilogue fixes. I'd repeat the original testing before committing. Richard
