This lets us use #ifdefs to determine which stage of the build we happen to be in, which is useful in the event we need to make changes to rustrt that are incompatible with the code generated by stage0. This should help pave the way to completing #6575, which will likely require changes to type signatures for spawn_fn & glue_fn in rustrt.

# 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).
|
|
