# 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). # Hack for passing flags into LIBUV, see below.
