I'm compiling a release note for LLD, and I'd like to get you guy's input about the status of the following subsystems. - Current MIPS support - Current AArch64 support - LTO I think AArch64 and LTO are added after the last release, so everything we've made so far should be in the next release note. MIPS's situation is different though. Rui -------------- next part -------------- An HTML attachment was scrubbed...

Hi Rui, We've added some lld notes to the main release notes, please reuse them.

I added some notes to release_39/docs/ReleaseNotes.rst at r277807. They describes new features implemented in LLD 3.9. In general LLD now supports both O32 and N64 MIPS ABIs. The most significant missed feature in both ABIs is multi-GOT support.

For full LTO, I'd say that the infrastructure is complete (modulo bugs we discover from time to time). There are plans to implement Thin, but that will require some work. -- Davide "There are no solved problems; there are only problems that are more or less solved" -- Henri Poincare
Not strictly within the list of topics you're asking for, but just in case it is useful. The ARM support is probably best described as experimental right now, it is missing exceptions support which will rule out a large subset of the programs we'd want to link and static linking. I'll hopefully be starting work on this in a week or so's time. I've not got anything else to add to the other replies with respect of the main topics.

Did you try building the kernel as well, or just userland?
