re PR tree-optimization/65215 (Bswap load miscompilation)
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.
