% "build38.lsp"
%
% Build a CSL REDUCE.
%
% Depending on how this file is used it will EITHER create a bootstrap
% version of REDUCE or a full and optimised one.
%
% The behaviour is determined by whether the version of CSL used to
% run it has a full complement of functions in the modules u01.c to u12.c.
%
%
%           slowr38 -z build38.lsp -D@srcdir=<DIR> -- log/boot38.log
%
% Builds a system "slowr38.img" that does not depend on any
% custom C code. The main use of this slow system is for profiling
% REDUCE and then compiling the hot-spots into C. Once that has been
% done this image is logically unnecessary.
%
%
%           r38 -z build38.lsp -D@srcdir=<DIR> -l log/full38.log
%
% Here the files u01.c to u12.c and u01.lsp to u12.lsp must already
% have been created, and that the r38 executable has them compiled in.
% The REDUCE source files that are compiled *MUST* be the same as those used
% to create this C code.

% This function runs a test file and sorts out what the top 350
% functions in it. It appends their names to "profile.dat".
%

% I need to talk a little about the interaction between profiling and
% patching.  Well firstly I arrange that whenever I run a profiling job
% I rebuild REDUCE with the latest paches. This may involve re-compiling
% the patches.red source.  Thus when a test is run the current patches
% will be in place. Patched functions are first defined with funny names
% (including a hash based on their definition) and then copied into place
% when a package is loaded. However MAPSTORE and the CSL instrumentation
% attributes their cost to the hash-extended name even though the
% functions may have been called via the simple one. Thus in the face
% of patches one can expect the profile data to refer to some names that
% are long and curious looking. Throughout all this I assume that there will
% never be embarassing collisions in my hash functions.

% The next lines have LOTS of hidden depth!  They restart CSL repeatedly
% so that each of the modules that has to be processed gets dealt with in
% a fresh uncluttered environment. The list of modules is fetched from
% a configuration file which must have 3 s-expressions in it. The first
% is a list of basic modules that must be built to get a core version of
% REDUCE. The second list identifies modules that can be built one the core
% is ready for use, while the last list indicates which modules have
% associated test scripts.
%
% when the modules have been rebuild the system does a restart that
% kicks it back into REDUCE by calling begin(). This then continues
% reading from the stream that had been the standard input when this
% job started. Thus this script MUST be invoked as
