Currently, Cargo.toml specifies Apache-2.0 OR MIT, but LICENSE.txt describes MIT OR NCSA. compiler-builtins is derived from LLVM's compiler-rt. LICENSE.txt correctly reflects the state of compiler-rt prior to relicensing on 2019-01-19, during which time software was available for use under either MIT or the University of Illinois NCSA license. After relicensing, however, compiler-rt is available for use only under Apache-2.0 with the LLVM exception; this is not reflected anywhere in the repository. Update the SPDX license identifier to `MIT AND Apache-2.0 WITH LLVM-exception AND (MIT OR Apache-2.0)`. Each AND portion covers something specific: * Apache-2.0 WITH LLVM-exception: this covers work that is derived from the LLVM repository since after the LLVM relicensing. * MIT: This covers work that is derived from LLVM before the LLVM relicensing (under MIT OR NCSA), as well as the vendored `libm` components. * MIT AND Apache-2.0: This ensures that any contributions to this repository, in addition to meeting the above required licenses, is also released for use under the Rust-standard Apache-2.0 with no LLVM exception. See also the parallel license update in rust-lang/libm [1].
