A test program of mine is around 20% slower when moving from FEniCS 1.1 to FEniCS 1.2. Are the C++ optimisation flags (parameters["form_compiler"]["cpp_optimize_flags"]) definitely applied when using Instant 1.2? I can't see them being used by any files in ~/.instant/cache, and I can't see any obvious use in instant/build.py. Manually rolling back to Instant 1.1 (with some surgery to UFC 2.2) fixes the performance issue.
