Hi all,
    I build successfully with speex-1.2rc2. And with speexdsp 1.2rc3, I
build with i386, X86_64, armv7 and armv7s all passed.
   But when I build for ARM64 (for iPhone 6), it failed with:
/Applications/Xcode.app/Contents/Developer/usr/bin/make  all-recursive
Making all in libspeexdsp
  CC       preprocess.lo
  CC       jitter.lo
  CC       mdf.lo
  CC       fftwrap.lo
  CC       filterbank.lo
  CC       resample.lo
In file included from resample.c:104:
./resample_neon.h:134:12: error: unknown register name 'q0' in asm
         : "q0");
           ^
./resample_neon.h:195:13: error: invalid output constraint '+l' in asm
                    [len] "+l" (len), [remainder] "+l" (remainder)
                          ^
2 errors generated.
make[2]: *** [resample.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2


As I googled out, I found it's said:

arm64 has a totally different instruction set.

See: http://people.linaro.org/~rikuvoipio/aarch64-talk/

The NEON assembly code needs a rewrite.



But I'm not familiar with ASM code. Could anyone help to fix that?

Best regards,
Evan JIANG
