To Generate crc32_constants.h
- Run make file in
../crc32-vpmsum
directory using following options and CRC polynomial. These options should use the same polynomial and order used by intel intrinisic functions
make crc32_constants.h CRC="0x11EDC6F41" OPTIONS="-x -r -c"
- move the generated
crc32_constants.h
into this directory - To understand more about this go here: https://masterchef2209.wordpress.com/2020/06/17/guide-to-intel-sse4-2-crc-intrinisics-implementation-for-simde/
