| 2 | +# the runtime. |

| 4 | +# Argument 1 is the target triple. |
| 5 | +# |
| 6 | +# This is not really the right place to explain this, but |
| 7 | +# for those of you who are not Makefile gurus, let me briefly |
| 8 | +# cover the $ expansion system in use here, because it |
| 9 | +# confused me for a while! The variable DEF_RUNTIME_TARGETS |
| 10 | +# will be defined once and then expanded with different |
| 11 | +# values substituted for $(1) each time it is called. |
| 12 | +# That resulting text is then eval'd. |
| 13 | +# |
| 14 | +# For most variables, you could use a single $ sign. The result |
| 15 | +# is that the substitution would occur when the CALL occurs, |
| 16 | +# I believe. The problem is that the automatic variables $< and $@ |
| 17 | +# need to be expanded-per-rule. Therefore, for those variables at |
| 18 | +# least, you need $$< and $$@ in the variable text. This way, after |
| 19 | +# the CALL substitution occurs, you will have $< and $@. This text |
| 20 | +# will then be evaluated, and all will work as you like. |
| 21 | +# |
| 22 | +# Reader beware, this explanantion could be wrong, but it seems to |
| 23 | +# fit the experimental data (i.e., I was able to get the system |
| 24 | +# working under these assumptions). |
