From the log data generated with --log-function-events we can create a detailed model of a function's lifetime. The parse processor displays several stats at a given time (percent and count) on a per function or byte basis: - preparsing - parsing - eager/lazy compiling - execution Bug: chromium:757467 Change-Id: I0ad5c9369c6a0628704e3caffb3920444ea603a9 Reviewed-on: https://chromium-review.googlesource.com/758641 Commit-Queue: Camillo Bruni <cbruni@chromium.org> Reviewed-by: Mathias Bynens <mathias@chromium.org> Cr-Commit-Position: refs/heads/master@{#50234}
