commitf0c4f33a4aa0760ba0e12a254b69d996442c9c5a (patch)
treea58a8730a79fbe2f600a777f5f276f719856de55 /jsimd_none.c
Adds libjpeg-turbo to our repository.
This change lands the original libjpeg-turbo 1.0.1 (source files only) and NASM 2.09.2 (required for assembling .asm files on Windows) to "deps/third_party". I will send more changes to land its build files and patches to integrate it into Chrome.
