This is an implementation of the conversion from UTF-8 to UTF-16 using SSE4

As explained at http://woboq.com/blog/utf-8-processing-using-simd.html


Use one of this command line to compile using 

# Scalar implementation
g++ benchmark.cc fromutf8-sse.cc -O3 -lQtCore

# SSE4.1 impelmentation
g++ benchmark.cc fromutf8-sse.cc -O3 -lQtCore -msse4.1

# SSE4.2
g++ benchmark.cc fromutf8-sse.cc -O3 -lQtCore -msse4.2

# For comparison with iconv
g++ benchmark.cc -O3 -lQtCore -DUSE_ICONV

# For comparison with u8u16  [http://u8u16.costar.sfu.ca/]
g++ benchmark.cc -O3 -lQtCore -DUSE_U8U16 u8u16/src/libu8u16.c  -mssse3 -include u8u16/config/ssse3_config.h -include stdio.h
# You will need the files from the u8u16 project.
