This is a regression introduced in 64-bit mode on the mainline by the switch to LRA, spotted by Jeff and fixed by Vladimir (much thanks to both). Tested on SPARC/Solaris, applied on the mainline. 2017-04-19 Eric Botcazou <ebotcazou@adacore.com> Vladimir Makarov <vmakarov@redhat.com> * config/sparc/predicates.md (input_operand): Add comment. Return true for any memory operand when LRA is in progress. * config/sparc/sparc.c (sparc_expand_move): Minor formatting fix. 2017-04-19 Eric Botcazou <ebotcazou@adacore.com> Jeff Law <law@redhat.com> * gcc.c-torture/compile/20170419-1.c: New test.
