These will tell you which opcodes have been executed most frequently in the current process, and, if Python was also built with -DDXPAIRS, will tell you which instruction _pairs_ were executed most frequently, which may help in choosing new instructions. If Python was built without -DDYNAMIC_EXECUTION_PROFILE, importing this module will raise a RuntimeError. If you're running a script you want to profile, a simple way to get the common pairs is: $ PYTHONPATH=$PYTHONPATH:/Tools/scripts ./python -i -O the_script.py --args ... > from analyze_dxp import * > s = render_common_pairs() > open('/tmp/some_file', 'w').write(s) iNtgetdxpsKCan't import analyze_dxp: Python built without -DDYNAMIC_EXECUTION_PROFILE.cCs#t|dko"t|dtS(s[Returns True if the Python that produced the argument profile was built with -DDXPAIRS.i(tlent isinstancetlist(tprofile((s1/usr/lib64/python2.7/Tools/scripts/analyze_dxp.pyt has_pairs(scCs'ttjtjaWdQXdS(s<Forgets any execution profile that has been gathered so far.N(t _profile_locktsysRt_cumulative_profile(((s1/usr/lib64/python2.7/Tools/scripts/analyze_dxp.pyt reset_profile/s c Csttj}t|r|xtttD]C}x:ttt|D]"}t||c|||7cs7dkrtnfd}dj|S(sRenders the most common opcode pairs to a string in order of descending frequency.
