# Base configuration for performance sensitive environments, see

# You should choose the fastest setjmp/longjmp for your platform.

# With the vast majority of compilers some of the 'undefined behavior'
# assumptions are fine, and produce smaller and faster code, so enable
# by default for performance oriented targets.  You may need to disable
# this for some compilers.
