f78aa16af1
On 32-bit Release builds, GCC warns about this line in this test,
../../tests/SkRasterPipelineTest.cpp:225:40:
error: ‘int __builtin_memcmp_eq(const void*, const void*, unsigned int)’
reading 8 bytes from a region of size 0 [-Werror=stringop-overflow=]
!memcmp(&data[j][0], &buffer[j][0], sizeof(buffer[j])));
~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I don't really see anything wrong, and I'm not really sure why it takes
offense here testing load_f16 and not in the very similar next chunk of
code testing load_af16. Anyway, it's simple enough to write a loop.
