+ The module initialisation code looks like this, roughly:
+
+ FN(__stginit_Foo) {
+ JMP_(__stginit_Foo_1_p)
+ }
+
+ FN(__stginit_Foo_1_p) {
+ ...
+ }
+
+ We have one version of the init code with a module version and the
+ 'way' attached to it. The version number helps to catch cases
+ where modules are not compiled in dependency order before being
+ linked: if a module has been compiled since any modules which depend on
+ it, then the latter modules will refer to a different version in their
+ init blocks and a link error will ensue.
+
+ The 'way' suffix helps to catch cases where modules compiled in different
+ ways are linked together (eg. profiled and non-profiled).
+
+ We provide a plain, unadorned, version of the module init code
+ which just jumps to the version with the label and way attached. The
+ reason for this is that when using foreign exports, the caller of
+ startupHaskell() must supply the name of the init function for the "top"
+ module in the program, and we don't want to require that this name
+ has the version and way info appended to it.
