# Pattern rule to print variables, e.g. make print-top_srcdir
print-%: FORCE
	@echo '$*'='$($*)'

# When invoking a sub-make, keep only the command line variable definitions
# matching the pattern in the filter function.
#
# e.g. invoking:
#   $ make A=1 C=1 print-MAKEOVERRIDES print-MAKEFLAGS
#
# with the following in the Makefile:
#   MAKEOVERRIDES := $(filter A=% B=%,$(MAKEOVERRIDES))
#
# will print:
#   MAKEOVERRIDES = A=1
#   MAKEFLAGS = -- A=1
#
# this is because as the GNU make manual says:
#   The command line variable definitions really appear in the variable
#   MAKEOVERRIDES, and MAKEFLAGS contains a reference to this variable.
#
# and since the GNU make manual also says:
#   variables defined on the command line are passed to the sub-make through
#   MAKEFLAGS
#
# this means that sub-makes will be invoked as if:
#   $(MAKE) A=1 blah blah
MAKEOVERRIDES := $(filter V=%,$(MAKEOVERRIDES))

# Previously, we directly invoked the well-known programs using $(shell ...)
# to construct build_id_string. However, that was problematic because:
#
# 1. When invoking a shell, GNU Make special-cases exit code 127 (command not
#    found) by not capturing the output but instead passing it through. This is
#    not done for any other exit code.
#
# 2. Characters like '#' (from these programs' output) would end up in make
#    variables like build_id_string, which would be wrongly interpreted by make
#    when these variables were used.
#
# Therefore, we should avoid having arbitrary strings in make variables where
# possible. The gen_id script used here hashes the output to construct a
# "make-safe" id.
#
# Also note that these lines need to be:
#
#     1. After including {hosts,builders}/*.mk, since they rely on the tool
#        variables (e.g. build_CC, host_STRIP, etc.) to be set.
#
#     2. Before including packages/*.mk (excluding packages/packages.mk), since
#        they rely on the build_id variables

# $PATH is not preserved between ./configure and make by convention. Its
# modification and overriding at ./configure time is (as I understand it)
# supposed to be captured by the AC_{PROG_{,OBJ}CXX,PATH_{PROG,TOOL}} macros,
# which will expand the program names to their full absolute paths. The notable
# exception is command line overriding: ./configure CC=clang, which skips the
# program name expansion step, and works because the user implicitly indicates
# with CC=clang that clang will be available in $PATH at all times, and is most
# likely part of the user's system.
#
# Therefore, when we "seed the autoconf cache"/"override well-known program
# vars" by setting AR=<blah> in our config.site, either one of two things needs
# to be true for the build system to work correctly:
#
#   1. If we refer to the program by name (e.g. AR=riscv64-gnu-linux-ar), the
#      tool needs to be available in $PATH at all times.
#
#   2. If the tool is _**not**_ expected to be available in $PATH at all times
#      (such as is the case for our native_cctools binutils tools), it needs to
#      be referred to by its absolute path, such as would be output by the
#      AC_PATH_{PROG,TOOL} macros.
#
# Minor note: it is also okay to refer to tools by their absolute path even if
# we expect them to be available in $PATH at all times, more specificity does
# not hurt.
