Commit Message

Masahiro Yamada Aug. 19, 2017, 8:49 a.m.
*.hash.c files are artifacts generated from *.gperf by using gperf.
Instead of running gperf, we conventionally version-control
*.hash.c_shipped files and copy them to *.hash.c during build.

It is true that this approach can minimize external tool dependency,
but we need to update the shipped files from time to time.  This
commit switches to build-time generation of the intermediate C files.
