[llvm-dev] state of the lld linker for aarch64
Hi, Some time ago there were some information about aarch64 support for the lld linker project: http://lld.llvm.org/open_projects.html#elf-aarch64 Right now there is no such information. Also there is some presentation described that the simple application can be linked using lld: http://llvm.org/devmtg/2016-03/Presentations/EuroLLVM%202016-%20New%20LLD%20linker%20for%20ELF.pdf What is the current state of the lld linker for the aarch64 architecture? If i'm able to link simple application, then how should i do it? Thanks a lot, Dima. -------------- next part -------------- An HTML attachment was scrubbed...

He should know more. cheers, --renato

He should know more.Here's some info on TLS. Review D18960 has the initial implementation for TLSDESC support: http://reviews.llvm.org/D18960 I've been occasionally testing FreeBSD/arm64 buildworld with lld and managed to get everything to link with an earlier version of D18960 and an equivalent set of workarounds as on FreeBSD/amd64. There is some TLS bug outstanding that caused all binaries to segfault at start, though. I plan to take another look at that once D18711 and D18960 land.
