17; Set the following to 1 if we have EDSP instructions
18;  (LDRD/STRD, etc., ARMv5E and later).
19OC_ARM_ASM_EDSP		*	1

21; Set the following to 1 if we have ARMv6 media instructions.
22OC_ARM_ASM_MEDIA	*	1
23
24; Set the following to 1 if we have NEON (some ARMv7)
25OC_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
29OC_ARM_CAN_UNALIGN	*	0
30
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.
