# -----------------------------
# Rebuilding this configuration
# -----------------------------

# On the use of stamps:
# Consider the example of tree-check.h. It is constructed with build/gencheck.
# A simple rule to build tree-check.h would be
# tree-check.h: build/gencheck$(build_exeext)
#	$(RUN_GEN) build/gencheck$(build_exeext) > tree-check.h
#
# but tree-check.h doesn't change every time gencheck changes. It would the
# nice if targets that depend on tree-check.h wouldn't be rebuild
# unnecessarily when tree-check.h is unchanged. To make this, tree-check.h
# must not be overwritten with a identical copy. One solution is to use a
# temporary file
# tree-check.h: build/gencheck$(build_exeext)
#	$(RUN_GEN) build/gencheck$(build_exeext) > tmp-check.h
#	$(SHELL) $(srcdir)/../move-if-change tmp-check.h tree-check.h
#
# This solution has a different problem. Since the time stamp of tree-check.h
# is unchanged, make will try to update tree-check.h every time it runs.
# To prevent this, one can add a stamp
# tree-check.h: s-check
# s-check : build/gencheck$(build_exeext)
#	$(RUN_GEN) build/gencheck$(build_exeext) > tmp-check.h
#	$(SHELL) $(srcdir)/../move-if-change tmp-check.h tree-check.h
#	$(STAMP) s-check
#
# The problem with this solution is that make thinks that tree-check.h is
# always unchanged. Make must be deceived into thinking that tree-check.h is
# rebuild by the "tree-check.h: s-check" rule. To do this, add a dummy command:
# tree-check.h: s-check; @true
# s-check : build/gencheck$(build_exeext)
#	$(RUN_GEN) build/gencheck$(build_exeext) > tmp-check.h
#	$(SHELL) $(srcdir)/../move-if-change tmp-check.h tree-check.h
#	$(STAMP) s-check
#
# This is what is done in this makefile. Note that mkconfig.sh has a
# move-if-change built-in

# would never come up.  As it turns out, if you use ccache with
# CCACHE_HARDLINK enabled, the compiler doesn't embed the current
# working directory in object files (-g absent, or -fno-working-dir
# present), and build and host are the same, fixincl for the host will
# build after fixincl for the build machine, getting a cache hit,
# thereby updating the timestamp of fixincl.o in the host tree.
# Because of CCACHE_HARDLINK, this will also update the timestamp in
# the build tree, and so fixincl in the build tree will appear to be

# Install with the gcc headers files, not the fixed include files, which we

#    useless for installation purposes and would rely on improper headers.
#  - Restore as much of the original state as possible.

# For parallelized check-% targets, this decides whether parallelization
# is desirable (if -jN is used).  If desirable, recursive make is run with
# check-parallel-$lang{,1,2,3,4,5} etc. goals, which can be executed in
# parallel, as they are run in separate directories.
# check-parallel-$lang{,1,2,3,4,5} etc. goals invoke runtest with
# GCC_RUNTEST_PARALLELIZE_DIR var in the environment and runtest_file_p
# dejaGNU procedure is overridden to additionally synchronize through
# a $lang-parallel directory which tests will be run by which runtest instance.
# Afterwards contrib/dg-extract-results.sh is used to merge the sum and log
# files.  If parallelization isn't desirable, only one recursive make
# is run with check-parallel-$lang goal and check_$lang_parallelize variable
# cleared to say that no additional arguments beyond $(RUNTESTFLAGS)
# should be passed to runtest.
#
# To parallelize some language check, add the corresponding check-$lang
# to lang_checks_parallelized variable and define check_$lang_parallelize
# variable.  This is the upper limit to which it is useful to parallelize the
# check-$lang target.  It doesn't make sense to try e.g. 128 goals for small
# testsuites like objc or go.
