This has been tested on powerpc/i688-darwin9 .. x86_64-darwin10,17,21 and the prototype aarch64-darwin branch on darwin21. OK for trunk? thanks Iain NOTE: As discussed in the PR, there are likely to be other changes to the _definitions_ of the module registration constructors. This patch only relates to the _references_ to those CTORs. --- 8< --- The symbols for module registration constructors need to be external or we get wrong code generated for targets that allow direct access to local symbol definitions.
