Add some comments to explain the gsi_move_before in case of load and why canonicalization of bswap into a rotation is only done for 16bit values. (pass_optimize_bswap::execute): Adapt for loop via gsi to make gsi refer to the statement just before cur_stmt. Ignore 16bit bswap that are already in canonical form. Adapt bswap_replace to removal of its gsi parameter. 2014-11-12 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/testsuite/ PR tree-optimization/63761 * gcc.c-torture/compile/pr63761.c: New test.
