ARM: always enable AEABI for ARMv6+ (49460970) · Commits · 戴 / test

Always enable AEABI for ARMv6+, as these use the double-word exclusives which must be passed an even register to avoid errors such as: /tmp/ccG2rCwe.s:905: Error: even register required -- `ldrexd r5,r6,[r7]' /tmp/ccG2rCwe.s:909: Error: even register required -- `strexd sl,r3,r4,[r7]' Signed-off-by:
