# Tools for caching Makefile variables that are "expensive" to compute.
#
# Here we want to help deal with variables that take a long time to compute
# by making it easy to store these variables in a cache.
#
# The canonical example here is testing for compiler flags.  On a simple system
# each call to the compiler takes 10 ms, but on a system with a compiler that's
# called through various wrappers it can take upwards of 100 ms.  If we have
# 100 calls to the compiler this can take 1 second (on a simple system) or 10
# seconds (on a complicated system).
#
# The "cache" will be in Makefile syntax and can be directly included.
# Any time we try to reference a variable that's not in the cache we'll
# calculate it and store it in the cache for next time.

# Include values from last time

# Usage:   $(call shell-cached,shell_command)
# Example: $(call shell-cached,md5sum /usr/bin/gcc)
#
# If we've already seen a call to this exact shell command (even in a
# previous invocation of make!) we'll return the value.  If not, we'll
# compute it and store the result for future runs.
#
# This is a bit of voodoo, but basic explanation is that if the variable
# was undefined then we'll evaluate the shell command and store the result
# into the variable.  We'll then store that value in the cache and finally
# output the value.
#
# NOTE: The $$(2) here isn't actually a parameter to __run-and-store.  We
# happen to know that the caller will have their shell command in $(2) so the
# result of "call"ing this will produce a reference to that $(2).  The reason

# (1) PHONY targets are always build
# (2) No target, so we better build it
# (3) Prerequisite is newer than target
# (4) The command line stored in the file named dir/.target.cmd
#     differed from actual command line. This happens when compiler

# (5) No dir/.target.cmd file (used to store command line)

#
# When a Kconfig string contains a filename, it is suitable for
# passing to shell commands. It is surrounded by double-quotes, and
# any double-quotes or backslashes within it are escaped by
# backslashes.
#
# This is no use for dependencies or $(wildcard). We need to strip the
# surrounding quotes and the escaping from quotes and backslashes, and
# we *do* need to escape any spaces in the string. So, for example:
#
# Usage: $(eval $(call config_filename,FOO))
#
# Defines FOO_FILENAME based on the contents of the CONFIG_FOO option,
# transformed as described above to be suitable for use within the
# makefile.
#
# Also, if the filename is a relative filename and exists in the source
# tree but not the build tree, define FOO_SRCPREFIX as $(srctree)/ to
# be prefixed to *both* command invocation and dependencies.
#
# Note: We also print the filenames in the quiet_cmd_foo text, and
# perhaps ought to have a version specially escaped for that purpose.
# But it's only cosmetic, and $(patsubst "%",%,$(CONFIG_FOO)) is good
# enough.  It'll strip the quotes in the common case where there's no
# space and it's a simple filename, and it'll retain the quotes when
# there's a space. There are some esoteric cases in which it'll print
# the wrong thing, but we don't really care. The actual dependencies
# and commands *do* get it right, with various combinations of single
# and double quotes, backslashes and spaces in the filenames.
