| michael@0 | 17 | ; Set the following to 1 if we have EDSP instructions |
| michael@0 | 18 | ; (LDRD/STRD, etc., ARMv5E and later). |
| michael@0 | 19 | OC_ARM_ASM_EDSP * 1 |
| michael@0 | 20 | |
| michael@0 | 21 | ; Set the following to 1 if we have ARMv6 media instructions. |
| michael@0 | 22 | OC_ARM_ASM_MEDIA * 1 |

| michael@0 | 24 | ; Set the following to 1 if we have NEON (some ARMv7) |
| michael@0 | 25 | OC_ARM_ASM_NEON * 1 |
| michael@0 | 26 | |
| michael@0 | 27 | ; Set the following to 1 if LDR/STR can work on unaligned addresses |
| michael@0 | 28 | ; This is assumed to be true for ARMv6 and later code |
| michael@0 | 29 | OC_ARM_CAN_UNALIGN * 0 |
| michael@0 | 30 | |
| michael@0 | 31 | ; Large unaligned loads and stores are often configured to cause an exception. |
| michael@0 | 32 | ; They cause an 8 cycle stall when they cross a 128-bit (load) or 64-bit (store) |
| michael@0 | 33 | ; boundary, so it's usually a bad idea to use them anyway if they can be |
| michael@0 | 34 | ; avoided. |
| michael@0 | 35 | |
| michael@0 | 36 | ; Set the following to 1 if LDRD/STRD can work on unaligned addresses |
