I think we need more details. Are the files the headers were generated from publicly available? Do they list any copyright/license information? > Are the register names and locations under copyright?

I would strongly suggest SDCC developers obtain legal advice on this topic, especially in light of Oracle v Google. Software Freedom Conservancy may be able to help with this: https://sfconservancy.org/ > For some targets, SDCC already has such files (e.g. > https://sourceforge.net/p/sdcc/code/HEAD/tree/trunk/sdcc/device/non-free/include/pic16/pic18f1320.h). I note this in the file you mention: * This file is generated automatically by the cinc2h.pl, 2016-04-13 17:23:42 UTC. In addition to the hardware vendors copyright issue, clearly this header is not the source form under the GPL's "preferred form for modification" requirements, nor under DFSG item 2 and therefore Debian cannot distribute it without the source. -- bye, pabs https://wiki.debian.org/PaulWise
