I'm trying to fix a patch to allow #pixman's #ARM#NEON#assembly code to build with clang. They perform a lot of mechanical changes to switch to the "unified" ARM assembly syntax (.syntax unified), supported by both #gcc and #clang.
With clang the code builds but fails 3 of the tests in the test suite with what appear to be unaligned accesses. With gcc, the test suite passes before and after the patches.
