I see the autobuild failed on the ARM64 squeak.cog.spur debug build because of some issue with BitBltArm64.c line 1536 
        /* Inner loop */
        for (; remain >= 256/destBPP; remain -= 256/destBPP) {
            __asm__ volatile (
                    /* Load source word (if necessary) and shuffle */
                    "cmp     %[unskew], %[src_bits]            \n\t"

No idea what "error: impossible constraint in 'asm'" means in this context. Ideas?
