Raw Blame History

# This is a procedure to define the targets for building
# the runtime.
#
# Argument 1 is the target triple.
#
# This is not really the right place to explain this, but
# for those of you who are not Makefile gurus, let me briefly
# cover the $ expansion system in use here, because it
# confused me for a while! The variable DEF_RUNTIME_TARGETS
# will be defined once and then expanded with different
# values substituted for $(1) each time it is called.
# That resulting text is then eval'd.
#
# For most variables, you could use a single $ sign. The result
# is that the substitution would occur when the CALL occurs,
# I believe. The problem is that the automatic variables $< and $@
# need to be expanded-per-rule. Therefore, for those variables at
# least, you need $$< and $$@ in the variable text. This way, after
# the CALL substitution occurs, you will have $< and $@. This text
# will then be evaluated, and all will work as you like.
#
# Reader beware, this explanantion could be wrong, but it seems to
# fit the experimental data (i.e., I was able to get the system
# working under these assumptions).
# when we're doing a snapshot build, we intentionally degrade as many
# features in libuv and the runtime as possible, to ease portability.
