Hi all, I'm updating OpenEmbedded-core's speexdsp from 1.2rc1 (when it still was a part of the speex source tree) to 1.2rc3. I found out that building the new version for aarch64 fails in resample_neon.h (the target machine is OE-core's default qemuarm64 target). This is the error message: .../speexdsp-1.2rc3/libspeexdsp/resample_neon.h:148:5: error: impossible constraint in 'asm' asm volatile (" cmp %[len], #0\n" ^ I haven't dealt with assembly code enough...
