|
||
|
|
#
|
||
|
|
# Notes:
|
||
|
|
# 1) This follows a Python convention for marking internal vs public functions.
|
||
|
|
# Internal functions are prefixed with "_".
|
||
|
|
|
||
|
|
# A simple testcase generator.
|
||
|
|
#
|
||
|
|
# Usage Notes:
|
||
|
|
#
|
||
|
|
# 1) The length of each parameter list must either be one, in which case the
|
||
|
|
# same value is used for each run, or the length must match all other
|
||
|
|
# parameters of length greater than one.
|
||
|
|
#
|
||
|
|
# 2) Values for parameters that vary across runs must appear in increasing
|
||
|
|
# order. E.g. nr_gen_shlibs = { 0 1 10 } is good, { 1 0 10 } is bad.
|
||
|
|
# This rule simplifies the code a bit, without being onerous on the user:
|
||
|
|
# a) Report generation doesn't have to sort the output by run, it'll already
|
||
|
|
# be sorted.
|
||
|
|
# b) In the static object file case, the last run can be used used to generate
|
||
|
|
# all the source files.
|
||
|
|
#
|
||
|
|
# TODO:
|
||
|
|
# 1) have functions call each other within an objfile and across
|
||
|
|
# objfiles to measure things like backtrace times
|
||
|
|
# 2) enums
|
||
|
|
#
|
||
|
|
# Implementation Notes:
|
||
|
|
#
|
||
|
|
# 1) The implementation would be a bit simpler if we could assume Tcl 8.5.
|
||
|
|
# Then we could use a dictionary to record the testcase instead of an array.
|
||
|
|
# With the array we use here, there is only one copy of it and instead of
|
||
|
|
# passing its value we pass its name. Yay Tcl. An alternative is to just
|
||
|
|
# use a global variable.
|
||
|
|
#
|
||
|
|
# 2) Because these programs can be rather large, we try to avoid recompilation
|
||
|
|
# where we can. We don't have a makefile: we could generate one but it's
|
||
|
|
# not clear that's simpler than our chosen mechanism which is to record
|
||
|
|
# sums of all the inputs, and detect if an input has changed that way.
