New Revision: 221033

Log:
	PR tree-optimization/65215
	* tree-ssa-math-opts.c (find_bswap_or_nop_load): Return false
	for PDP endian targets.
	(perform_symbolic_merge, find_bswap_or_nop_1, find_bswap_or_nop):
	Fix up formatting issues.
	(bswap_replace): Likewise.  For BYTES_BIG_ENDIAN, if the final access
	size is smaller than the original, adjust MEM_REF offset by the
	difference of sizes.  Use is_gimple_mem_ref_addr instead of
	is_gimple_min_invariant test to avoid adding address temporaries.

	* gcc.c-torture/execute/pr65215-1.c: New test.
	* gcc.c-torture/execute/pr65215-2.c: New test.
	* gcc.c-torture/execute/pr65215-3.c: New test.
	* gcc.c-torture/execute/pr65215-4.c: New test.
	* gcc.c-torture/execute/pr65215-5.c: New test.
