7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; Solaris kernel modules use non-standard ELF constructions to express inter-
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; module dependencies, namely a DT_NEEDED tag inside a relocatable ELF file.
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; The Solaris linker can generate these automatically; since yasm can't
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; produce an ELF file which quite fits Solaris's requirements we create one
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; manually using flat binary output format. In order to save unnecessary
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; repetition, this file defines macros for the repetitive bits which can be
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; reused by the actual dependency objects. Certainly not the nicest way to
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; get the effect we want, but probably a reasonable compromise between
7473cac51fff527528e0a5b8768488ccc9acfee4vboxsync; cleanness and required effort.
