@minsoochoo@mastodon.bsd.cafe Given that LLDB has a minidump plugin, can’t we just load them directly? Is there anything missing from the minidump that would need to be added to the ELF core?

@jdevlieghere@mastodon.social Minidump in LLVM actually means Windows minidump that is produced after BSOD. The name is bit misleading since FreeBSD also has minidump that serves a similar purpose but has a totally different structure. llvm::file_magic::minidump_nt and minidump-nt as a plugin name would be better names. Another issue is that FreeBSD minidump is not stable which has versioning per architecture. Currently LLDB and KGDB don’t need to care about the versioning part as it is handled under the kvm interface. Generating ELF core from minidump reduces maintenance burden on the debugger side, so it’s better to handle minidump on FreeBSD and forget about it on debugger side.
