Considering Upgrade to LLVM 4.0 #37609 github issue, I see some work in progress for making rustc supporting upcoming LLVM 4.0.0.
Currently, LLVM 4.0.0 has RC1 release out, RC2 will arrive soon (Feb 2), and final realase is expected for near Feb 21.
I recently tried to compile rustc with LLVM 4.0.0-rc1 to see the status (at OpenBSD, we expect to ship LLVM 4.0.0 in ports quickly, and as rustc is by default linked with LLVM from ports, I take a look at it), and I was suprised to see that
rustllvm doesn’t link at all with
nightly for now.
For now, I think rustc port under OpenBSD will be build with embedded LLVM version, but I hope it is only a temporary measure (the build time grows a lot).
So I would like to know the current status of supporting LLVM 4.0.0, to know if I mess myself in some way to not be able to just link, or if it is currently expected.
And thanks for your work !
