# Upstream includes armv7hl support as some non-integrated 'contrib'

%description
American fuzzy lop uses a novel type of compile-time instrumentation
and genetic algorithms to automatically discover clean, interesting
test cases that trigger new internal states in the targeted
binary. This substantially improves the functional coverage for the
fuzzed code. The compact synthesized corpuses produced by the tool are
also useful for seeding other, more labor- or resource-intensive
testing regimes down the road.

Compared to other instrumented fuzzers, afl-fuzz is designed to be
practical: it has a modest performance overhead, uses a variety of
highly effective fuzzing strategies, requires essentially no
configuration, and seamlessly handles complex, real-world use cases -
say, common image parsing or file compression libraries.


%package clang
Summary:       Clang and clang++ support for %{name}
Requires:      %{name} = %{version}-%{release}
Requires:      clang(major) = %{clang_major}


%description clang
This subpackage contains clang and clang++ support for
%{name}.


%package clang-fast
Summary:       Fast clang and clang++ support for %{name}
Requires:      %{name} = %{version}-%{release}
Requires:      clang(major) = %{clang_major}


%description clang-fast
This subpackage contains fast clang and clang++ support for
%{name}.

The code in this package allows you to instrument programs for AFL using
true compiler-level instrumentation, instead of the more crude
assembly-level rewriting approach taken by afl-gcc and afl-clang.
