Fixing the ifdefs there are errors in the 64 bit code.
Here are 2 examples

r1081 fixes ifdefs so arm64 will be compiled, but armv7 32 bit will not.
A gyp change to enable arm64 is not checked in, as there are compile errors 
that need to be resolved.
Follow Getting Started ios arm64 instructions to repro.

Breaks into 4 issues:
bgt -> b.gt
v1.8b-v3.8b -> use , not -
mov v1,v2 -> use or v1, v2, v2
stride -> cast to ptrdiff_t

movi expects a constant, not an expression
mov doesnt work - use orr
index expects no register size. e.g. "ld4        {v0.b,v1.b,v2.b,v3.b}[0], 
[%0], #4       \n"  // load 1 pixel ARGB0.
strides need to be assigned to an lvalue.

width value issue unknown - works in most cases?
../../source/scale_neon64.cc:533:10: warning: value size does not match 
register size specified by the constraint and modifier [-Wasm-operand-widths]
    "+r"(dst_width),     // %2

Frank, I could compile example code with ld1 {v1.8b-v3.8b} inline assembly on 
clang 3.5. clang 3.5 seems to support the extensions used in row_neon64.cc 
code. Which version of clang is being used for iOS build?

Current libyuv chromium deps pull in clang 3.4

bash-3.2$ c++ --version
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)

GoogleCodeExporter commented 9 years ago 
It would be best if code can work on clang 3.4 but if its not possible the 
following check could be added to row.h

// clang >= 3.5.0 required for Arm64.
#if defined(__clang__) && defined(__aarch64__) && !defined(LIBYUV_DISABLE_NEON)
#if (__clang_major__ > 3) || (__clang_major__ == 3 && (__clang_minor__ >= 5))
#define LIBYUV_DISABLE_NEON
#endif  // clang >= 3.5
#endif  // __clang__

GoogleCodeExporter commented 9 years ago 
Since the changes required for clang 3.4 are not too many, we can support clang 
3.4. However, if possible it may be a good idea to migrate iOS to use clang 3.5 
in future.

But the build is broken for xcode 6

Original comment by fbarch...@chromium.org on 24 Sep 2014 at 3:16

GoogleCodeExporter commented 9 years ago 
The problem seems to be with the xcode as it has problems with proper AArch64 
assembly code. For example, ARM ARM, in Section C.1.2.4, says range syntax for 
load/store is valid. However xcode has problems with ld1 {v0.8b-v3.8b} syntax. 
From what I can see, the issue is not with gcc or clang as such.
