  16. ; Set the following to 1 if we have EDSP instructions
  17. ; (LDRD/STRD, etc., ARMv5E and later).
  18. OC_ARM_ASM_EDSP * @HAVE_ARM_ASM_EDSP@
  19. ; Set the following to 1 if we have ARMv6 media instructions.
  20. OC_ARM_ASM_MEDIA * @HAVE_ARM_ASM_MEDIA@
  21. ; Set the following to 1 if we have NEON (some ARMv7)
  22. OC_ARM_ASM_NEON * @HAVE_ARM_ASM_NEON@
  23. ; Set the following to 1 if LDR/STR can work on unaligned addresses
  24. ; This is assumed to be true for ARMv6 and later code
  25. OC_ARM_CAN_UNALIGN * 0
  26. ; Large unaligned loads and stores are often configured to cause an exception.
  27. ; They cause an 8 cycle stall when they cross a 128-bit (load) or 64-bit (store)
  28. ; boundary, so it's usually a bad idea to use them anyway if they can be
  29. ; avoided.
  30. ; Set the following to 1 if LDRD/STRD can work on unaligned addresses
  31. OC_ARM_CAN_UNALIGN_LDRD * 0
