Therefore, the recommended and only supported way of using NEON/VFP in the
|
||||
kernel is by adhering to the following rules:
|
||||
* isolate the NEON code in a separate compilation unit and compile it with
|
||||
'-mfpu=neon -mfloat-abi=softfp';
|
||||
'-march=armv7-a -mfpu=neon -mfloat-abi=softfp';
|

* issue the calls to kernel_neon_begin(), kernel_neon_end() as well as the calls
|
||||
into the unit containing the NEON code from a compilation unit which is *not*
|
||||
built with the GCC flag '-mfpu=neon' set.
