mercury/browser/Mmakefile
Zoltan Somogyi d56de30e9d Remove most of the junk from the command lines executed by make when building 
Estimated hours taken: 12
Branches: main

Remove most of the junk from the command lines executed by make when building
the compiler and by bootcheck when building test cases. We do this by moving
the junk into files consulted via the --flags option.

After this change, it is actually possible to see in a glance not just which
files are being compiled but also with which options. The size of the output
(measured in bytes) from a bootcheck is now only about 40% of what is was
before.

configure.in:
	Remember the path to the bootstrap compiler and the flags it should be
	invoked with separately. Put the flags into the FLAGS files in various
	directories.

	Test whether the default install directory actually exists, so that
	the -L and -R linker options referring to this directory are passed
	to the C compiler only if it does.

Mmake.common.in:
	Comment out a bunch of additions of MCFLAGS, the ones whose contents
	are now in FLAGS files.

	Conform to the changes in configure.in.

	Add a template rule for the dependencies of the FLAGS files.

Mmake.workspace:
	Comment out a bunch of additions of MCFLAGS, the ones whose contents
	are now in FLAGS files. In some cases, add references to the FLAGS
	files.

Mmakefile:
	When rebuilding Mmake.common, rebuild only Mmake.common, not all files
	created by configure.

analysis/ANALYSIS_FLAGS.in:
browser/MDB_FLAGS.in:
compiler/COMP_FLAGS.in:
deep_profiler/PROF_FLAGS.in:
library/LIB_FLAGS.in:
mdbcomp/MDBCOMP_FLAGS.in:
profiler/DEEP_FLAGS.in:
slice/SLICE_FLAGS.in:
tests/TESTS_FLAGS.in:
	Add these files, which each contain the junk flags (the flags which are
	the same on every invocation and mostly just clutter up compiler
	command lines) that are needed on each compiler invocation in the
	relevant directory. Besides the results of configuration (word size
	etc), and the paths to other parts of the system, these files mostly
	control which warnings are enabled.

	Restrict the list of directories in -I options to what is sensible;
	for example, don't specify -I../analysis in the deep_profiler
	directory.

*/.nocopyright:
	Don't require copyright notices in FLAGS files, since that would make
	them invalid.

library/INTER_FLAGS:
	Add this file, which contains the flags enabled with intermodule
	optimization.

tests/WS_FLAGS.ws:
	Add this file. Unlike the .in files, which processed by config.status
	based on the results of autoconfiguration, this one is processed to
	specify the location of the workspace being tested.

analysis/Mmakefile:
browser/Mmakefile:
compiler/Mmakefile:
deep_profiler/Mmakefile:
library/Mmakefile:
mdbcomp/Mmakefile:
profiler/Mmakefile:
tests/Mmakefile:
	Include the relevant directory's FLAGS file on the command line, to
	replace all the additions to MCFLAGS in ../Mmake.common and in
	../Mmake.workspace, and in some cases, the directory-specific Mmakefile
	itself.

	Build the directory's FLAGS file before executing the depend target,
	since most compiler options beyond --generate-dependencies come from
	there.

	Delete the FLAGS files generated by config.status when doing "make
	clean".

tests/Mmakefile:
	Allow the environment to define DIFF_OPTS.

runtime/Mmakefile:
	Use an option to tell config.status what to rebuild, not some
	environment variables.

tests/invalid/Mercury.options:
	For two test cases, reset an option that is set in tests/WS_FLAGS,
	to match the options the affected tests were compiled with before.

tests/invalid/*.err2:
	Update these expected files to account for the use of error_util
	in error messages by previous changes to the compiler. These expected
	output files are used only with --use-subdirs.

tests/warnings/Mmakefile:
	For all test cases, reset an option that is set in tests/WS_FLAGS,
	to match the options the tests were compiled with before.

scripts/prepare_tmp_dir_grade_part
	Copy the flags files when creating the subdirectories of tmp_dir.

scripts/mgnuc.in:
	Provide a mechanism, a per-directory .mgnuc_opts file, for specifying
	the options that are required for every C file in a directory. The
	intention is to use this for -I../library etc, but this is not done
	yet; one thing at a time.

tools/bootcheck:
	Copy the FLAGS files when creating stage2 and stage3.

	Don't specify the compiler options that are now in FLAGS files.

	Fill in the location of the workspace in tests/WS_FLAGS before running
	the tests.

	Provide a mechanism (a file ~/.bootcheck_diff_opts) to allow the user
	to specify what options to invoke diff with.

	Move the setting of MMAKE_USE_SUBDIRS and MMAKE_USE_MMC_MAKE after
	we have built stage1, and always copy the profilers if --use-subdirs
	is set. The old ways of doing things caused problems if bootcheck
	was given --use-subdirs but stage1 doesn't use subdirs: the bootcheck
	modified the stage1 slice, profiler and deep_profiler directories.
