bootcheck:
By default, execute all the tests after verifying that the compiler
compiles itself to a fix point. Don't execute the tests if called
with the -t option.
makebatch:
Pass the -t option to bootcheck if makebatch is itself called with -t.
test_mercury:
Run the tests on the bootstrapped compiler *before* installing it,
and don't install it unless it passes all the tests.
Cycle through a list of different parameter settings, so that
in general different nightly runs use different sets of options.
Call bootcheck with -r, since some of these options may cause
a compilation model difference between the current and new compiler.
list.*:
Lists of parameter settings for various machines.
expand_params:
Expand the paramater settings from one line of a list.x file
into a Mmake.param file
cur_param:
Report which line in a list.x file is the current one.
next_param:
Advance the current line in a list.x file. When we reach the end,
we start again at the start.
