# Our tests do actual crypto and lots of work, the tradeoff for -O1 is well worth it.
# Ideally we would only do this in profile.test, but profile.test only applies to
# the test binary, not dependencies, which means most of the critical code still
# gets compiled as -O0. See
# Our tests do actual crypto and lots of work, the tradeoff for -O2 is well

# It appears some minimal optimizations are required to inline many std methods
# and reduce the otherwise-substantial time spent in std self-checks. We do so
# here but ensure we keep LTO disabled as otherwise we're re-optimizing all our
# dependencies every time we make any local changes.
