gzipped C++ source code

For the attached C++ source code, recent gcc trunk does this:

$ ../results/bin/gcc -c -O3 -march=3Dznver2 -ffast-math bug966.cc
during GIMPLE pass: slp
equalizer.cc: In function =E2=80=98void eq_update(void*, void*)=E2=80=99:

0x20fe038 vectorizable_simd_clone_call(vec_info*, _stmt_vec_info*,
gimple_stmt_iterator*, gimple**, _slp_tree*, vec<stmt_info_for_cost, va_hea=

        ../../trunk.year/gcc/tree-vect-stmts.cc:0
