2017-10-19[ARM] PR 82445 - suppress 32-bit aligned ldrd/strd peepholing with ↵Richard Earnshaw7-7/+59
-mno-unaligned-access Peephole patterns exist in the arm backend to spot load/store operations to adjacent memory operations in order to convert them into ldrd/strd instructions. However, when we have strict alignment enforced, then we can only do this if the accesses are known to be 64-bit aligned; this is unlikely to be the case for most loads. The patch adds some alignment checking to the code that validates the addresses for use in the peephole patterns. This should also fix incorrect generation of ldrd/strd with unaligned accesses that could previously have occurred on ARMv5e where all such operations must be 64-bit aligned. I've added some new tests as well. In doing so I discovered that the ldrd/strd peephole tests could never fail since they would match the source file name in the scanned assembly as well as any instructions of the intended type. I've fixed those by tightening the scan results slightly. gcc: * config/arm/arm.c (align_ok_ldrd_strd): New function. (mem_ok_for_ldrd_strd): New parameter align.

The functions all call foo and therefore need a stack frame what makes them subject to shrink wrapping. Also all the additional instructions in the function body makes it fragile wrt instruction scheduling. Just set a global variable instead to circumvent this. gcc/testsuite/ChangeLog: 2017-10-18 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * gcc.target/s390/zvector/vec-cmp-2.c (all_eq_double, all_ne_double, all_gt_double) (all_lt_double, all_ge_double, all_le_double) (any_eq_double, any_ne_double, any_gt_double) (any_lt_double, any_ge_double, any_le_double) (all_eq_int, all_ne_int, all_gt_int) (all_lt_int, all_ge_int, all_le_int) (any_eq_int, any_ne_int, any_gt_int) (any_lt_int, any_ge_int, any_le_int): Set global variable instead of calling foo().
