This lets the C++ code in the rt handle the (slightly) tricky parts of random number generation: e.g. error detection/handling, and using the values of the `#define`d options to the various functions.

# 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).
|
|
|
