Hello, Compiling with "-march=armv7-a -mtune=cortex-a15 -mbe8" produces code that appears to change the order of words. For example, the word-wise optimized strcpy in musl changes "/dev/fd/" into "/fd//dev". Removing "mtune=cortex-a15" works around the problem. Presumably this is due to some instructions used in cortex-a15 mode that assume little endian data, when -mbe8 requires otherwise.
Thanks, Jason $ armeb-pc-linux-gnueabi-gcc -v Using built-in specs.
