@q3k What file is this extracted from? the liblzma_la-crc64-fast.o from the original mail?

@astrid The symbol names from the .o are just fanfiction, they're just made to look like legit liblzma symbols. But yes, the function at 0x1860 in the 5.6.0 .o seems to be what I call bd_elf_lookup_hash. 0x0a8a0 is what I call bd_hash (even though I now know it's not a hash). @astrid The trie? In liblzma_la-crc64-fast.o it's at 0xC340 (has_child masks) and 0xAEE0 (node info). Here is the parser, but so far I've only seen one version of this: https://gist.github.com/Riatre/527a34d2e4e0ed4770353a3cc4a6e136 (Offsets hardcoded here is for https://snapshot.debian.org/archive/debian/20240321T160517Z/pool/main/x/xz-utils/liblzma5_5.6.0-0.2_amd64.deb) |
@astrid I took this from a 5.6.1 fedora build of liblzma. But it should also be extractable from that .o.
