d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; Solaris kernel modules use non-standard ELF constructions to express inter-
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; module dependencies, namely a DT_NEEDED tag inside a relocatable ELF file.
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; The Solaris linker can generate these automatically; since yasm can't
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; produce an ELF file which quite fits Solaris's requirements we create one
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; manually using flat binary output format. In order to save unnecessary
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; repetition, this file defines macros for the repetitive bits which can be
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; reused by the actual dependency objects. Certainly not the nicest way to
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; get the effect we want, but probably a reasonable compromise between
d00f0155af9a9a671eb08a0dc30f5ea0a379c36cayznaga; cleanness and required effort.
