# A helper functions for dealing with lazily-evaluated, expensive operations..  Spinning
# up a python process to, for exaxmple, parse a TOML file is expensive, and we must wait
# until the TOML files are on-disk before we can parse them.  This means that we cannot
# use `:=` (since we do not want to evaluate these rules now, we want to evaluate them
# when we use them, so we use `=`) however we also do not want to re-evaluate them
# multiple times.  So we define a caching mechanism where the rules are still lazily
# evaluated, but we cache the value such that the second time around we don't have to
# re-evaluate them.  Usage example:
#
# EXPENSIVE_OPERATION = $(shell prog args...)
# CACHED_RESULT = $(call hit_cache,EXPENSIVE_OPERATION)
#
# The first time you use `$(CACHED_RESULT)`, it will invoke `$(EXPENSIVE_OPERATION)`,
# but after that point, it will not, unless `$(EXPENSIVE_OPERATION)` evaluated to the
# empty string, in which case it will be re-evaluated.

# CSL_NEXT_GLIBCXX_VERSION is a triple of the symbols representing support for whatever
# the next libstdc++ version would be. This is used for two things.
# 1. Whether the system libraries are new enough, if we need to use the libs bundled with CSL
# 2. To know which libstdc++ to load at runtime
# We want whichever libstdc++ library is newer, because if we don't it can cause problems.
# While what CSL bundles is quite bleeding-edge compared to what most distros ship, if someone
# tries to build an older branch of Julia, the version of CSL that ships with it may be
# relatively old. This is not a problem for code that is built in BB, but when we build Julia
# with the system compiler, that compiler uses the version of `libstdc++` that it is bundled
# with, and we can get linker errors when trying to run that `julia` executable with the
# `libstdc++` that comes from the (now old) BB-built CSL.
# To fix this, we take note when the system `libstdc++.so` is newer than whatever we
# would get from CSL (by searching for a `GLIBCXX_X.Y.Z` symbol that does not exist
# in our CSL, but would in a newer one), and default to `USE_BINARYBUILDER_CSL=0` in
# this case. This ensures that we link against a version with the symbols required.
# We also check the system libstdc++ at runtime in the cli loader library, and
# load it if it contains the version symbol that indicates that it is newer than the one
# shipped with CSL. Although we do not depend on any of the symbols, it is entirely
# possible that a user might choose to install a library which depends on symbols provided
# by a newer libstdc++. Without runtime detection, those libraries would break.

#  * libopenlibm, because Windows has an untrustworthy libm, and we want to use ours more than theirs
#  * libstdc++, because while performing `libstdc++` probing we need to
#    know the path to the bundled `libstdc++` library.
#  * libjulia-internal, which must always come second-to-last.
#  * libjulia-codegen, which must always come last
#
# We need these four separate variables because:
#  * debug builds must link against libjuliadebug, not libjulia
#  * install time relative paths are not equal to build time relative paths (../lib vs. ../lib/julia)
# That second point will no longer be true for most deps once they are placed within Artifacts directories.
# Note that we prefix `libjulia-codegen` and `libjulia-internal` with `@` to signify to the loader that it
# should not automatically dlopen() it in its loading loop, it is "special" and should happen later.
# We do the same for `libstdc++`, and explicitly place it _after_ `libgcc_s`, and `libm` since `libstdc++`
# may depend on those libraries (e.g. when USE_SYSTEM_LIBM=1)
