14 exceeds a threshold, we identify a hot loop and perform second-level
15 instrumentation on the hot loop region (the instructions between the
28 first machine-code basic block of the hot loop region.
31 exits from the hot region? 3 step process.
33 1) Do a DFS from the first machine-code basic block of the hot loop
36 2) Do a DFS from the last machine-code basic block of the hot loop
39 the end BB of the hot region).
41 3) Mark BBs which end in edges that exit the hot region; we need to
48 through the hot region. Silently fail if we need more than 64 bits.
58 verify our assumption that we picked a hot back-edge in first-level
60 exit edge from the hot trace is less than 10% of the number of
72 phase behavior from us (when some funcs/traces stop being hot and
73 others become hot.)
96 each machine code basic block we think is in the hot region into the
