re PR tree-optimization/51583 (One more missing force_gimple_operand in SRA)
2011-12-19 Martin Jambor <mjambor@suse.cz>
PR tree-optimization/51583
* tree-sra.c (load_assign_lhs_subreplacements): Call
force_gimple_operand_gsi when necessary also in case of no
corresponding replacement on the RHS.
* testsuite/gcc.dg/tree-ssa/pr51583.c: New test.
