+/* 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:
+http://llvm.org/docs/LibFuzzer.html
