# Annotator for cachegrind/callgrind.
#
# File format is described in /docs/techdocs.html.
#
# Performance improvements record, using cachegrind.out for cacheprof, doing no
# source annotation (irrelevant ones removed):
# user time
# 1. turned off warnings in add_hash_a_to_b() 3.81 --> 3.48s
# [now add_array_a_to_b()]
# 6. make line_to_CC() return a ref instead of a hash 3.01 --> 2.77s
#
#10. changed file format to avoid file/fn name repetition 2.40s
# (not sure why higher; maybe due to new '.' entries?)
#11. changed file format to drop unnecessary end-line "."s 2.36s
# (shrunk file by about 37%)
#12. switched from hash CCs to array CCs 1.61s
#13. only adding b[i] to a[i] if b[i] defined (was doing it if
# either a[i] or b[i] was defined, but if b[i] was undefined
# it just added 0) 1.48s
#14. Stopped converting "." entries to undef and then back 1.16s
#15. Using foreach $i (x..y) instead of for ($i = 0...) in
# add_array_a_to_b() 1.11s
#
# Auto-annotating primes:
#16. Finding count lengths by int((length-1)/3), not by
# commifying (halves the number of commify calls) 1.68s --> 1.47s
