Comment (by bdubbs@…):
Rust builds it's own version of llvm. Interestingly, it is current:
5.0.1.
That is one of the reasons rust takes so long to build. llvm in the book
is 22 SBU and rust is 33 SBU. If they used system llvm, it would be a LOT
faster.
I'll note that I do have:
/tmp/rustc/rustc-1.23.0-src/build/x86_64-unknown-linux-gnu/llvm/bin/llvm-
config
but I generally do not do a DESTDIR install other than to look at files.
In the case of rust, it seems to ignore the exported DESTDIR variable.
I note that I have:
$ du -sh .cargo
547M .cargo
Tell me again why upstream has gone to rustc/cargo?
