My machine have rust nightly-2020-03-24, I want to compile cross-compile crate core. But the command rustup component add rust-src
install newest version of rust-src, which rustc-2020-03-24 can't build (due to new feature llvm-asm). How can I install old version of rust-src?

If not already installed, you can get a specific version of a component by specifying the toolchain when calling rustup
(like +stable
, +1.44
, etc). In your case:
rustup +nightly-2020-03-24 component add rust-src
The source can then be found in ~/.rustup/toolchains/nightly-2020-03-24-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/
.
