18 ; (LDRD/STRD, etc., ARMv5E and later).

21 ; Set the following to 1 if we have ARMv6 media instructions.
22 OC_ARM_ASM_MEDIA * 1

24 ; Set the following to 1 if we have NEON (some ARMv7)
25 OC_ARM_ASM_NEON * 1

27 ; Set the following to 1 if LDR/STR can work on unaligned addresses
28 ; This is assumed to be true for ARMv6 and later code
29 OC_ARM_CAN_UNALIGN * 0

31 ; Large unaligned loads and stores are often configured to cause an exception.
32 ; They cause an 8 cycle stall when they cross a 128-bit (load) or 64-bit (store)
33 ; boundary, so it's usually a bad idea to use them anyway if they can be
34 ; avoided.
