9e7973fa 3# This file specifies an array-of-hashes that define snippets of code that
24fb648d
DM
4# can be run by various measurement and profiling tools.
5#
6# The basic idea is that any time you add an optimisation that is intended
7# to make a particular construct faster, then you should add that construct
8# to this file.
9#
10# Under the normal test suite, the test file benchmarks.t does a basic
11# compile and run of each of these snippets; not to test performance,
12# but just to ensure that the code doesn't have errors.
13#
14# Over time, it is intended that various measurement and profiling tools
15# will be written that can run selected (or all) snippets in various
16# environments. These will not be run as part of a normal test suite run.
17#
9e7973fa
DM
18# It is intended that the tests in this file will be lightweight; e.g.
19# a hash access, an empty function call, or a single regex match etc.
20#
24fb648d
DM
21# This file is designed to be read in by 'do' (and in such a way that
22# multiple versions of this file from different releases can be read in
23# by a single process).
24#

DM
25# The top-level array has name/hash pairs (we use an array rather than a
26# hash so that duplicate keys can be spotted) Each name is a token that
27# describes a particular test. Code will be compiled in the package named
28# after the token, so it should match /^(\w|::)+$/a. It is intended that
29# this can be used on the command line of tools to select particular
30# tests.
31# In addition, the package names are arranged into an informal hierarchy
32# whose top members are (this is subject to change):
33#
34# call:: subroutine and method handling
35# expr:: expressions: e.g. $x=1, $foo{bar}[0]
84721d61 36# func:: perl functions, e.g. func::sort::...
9e7973fa
DM
37# loop:: structural code like for, while(), etc
38# regex:: regular expressions
39# string:: string handling
24fb648d 40#
9e7973fa
DM
41#
42# Each hash has three fields:
24fb648d
DM
43#
44# desc is a description of the test
45# setup is a string containing setup code
46# code is a string containing the code to run in a loop
47#
48# So typically a benchmark tool might do something like
49#
50# eval "package $token; $setup; for (1..1000000) { $code }"
9e7973fa
DM

52# Currently the only tool that uses this file is Porting/bench.pl;
53# try C<perl Porting/bench.pl --help> for more info
