/* libfuzzer test code for oniguruma

 * author: Hanno Böck, license: CC0/public domain

Usage:

* compile oniguruma with something like

	./configure CC=clang LD=clang CFLAGS="-fsanitize-coverage=edge -fsanitize=address" \

		LDFLAGS="-fsanitize-coverage=edge -fsanitize=address"

* Compile libfuzzer stub and link against static libonig.a and libFuzzer.a:

	clang++ libfuzzer-onig.cpp src/.libs/libonig.a libFuzzer.a -o libfuzzer-onig \

		-fsanitize-coverage=edge -fsanitize=address

* Put sample patterns in directory "in/"

* Run

	./libfuzzer-onig in

Consult libfuzzer docs for further details and how to create libFuzzer.a:
