31 # The file format is simple, basically printing the cost centre for every
32 # source line, grouped by files and functions. The details are in
33 # Cachegrind's manual.
35 #----------------------------------------------------------------------------
36 # Performance improvements record, using cachegrind.out for cacheprof, doing no
37 # source annotation (irrelevant ones removed):
39 # 1. turned off warnings in add_hash_a_to_b() 3.81 --> 3.48s
40 # [now add_array_a_to_b()]
41 # 6. make line_to_CC() return a ref instead of a hash 3.01 --> 2.77s
43 #10. changed file format to avoid file/fn name repetition 2.40s
44 # (not sure why higher; maybe due to new '.' entries?)
45 #11. changed file format to drop unnecessary end-line "."s 2.36s
46 # (shrunk file by about 37%)
47 #12. switched from hash CCs to array CCs 1.61s
48 #13. only adding b[i] to a[i] if b[i] defined (was doing it if
49 # either a[i] or b[i] was defined, but if b[i] was undefined
50 # it just added 0) 1.48s
51 #14. Stopped converting "." entries to undef and then back 1.16s
52 #15. Using foreach $i (x..y) instead of for ($i = 0...) in
53 # add_array_a_to_b() 1.11s
55 # Auto-annotating primes:
56 #16. Finding count lengths by int((length-1)/3), not by
57 # commifying (halves the number of commify calls) 1.68s --> 1.47s

72 # CCs are arrays, the counts corresponding to @events, with 'undef'
73 # representing '.'. This makes things fast (faster than using hashes for CCs)
74 # but we have to use @sort_order and @show_order below to handle the --sort and
75 # --show options, which is a bit tricky.
