Implement flexible target specification Removes all target-specific knowledge from rustc. Some targets have changed during this, but none of these should be very visible outside of cross-compilation. The changes make our targets more consistent. iX86-unknown-linux-gnu is now only available as i686-unknown-linux-gnu. We used to accept any value of X greater than 1. i686 was released in 1995, and should encompass the bare minimum of what Rust supports on x86 CPUs. The only two windows targets are now i686-pc-windows-gnu and x86_64-pc-windows-gnu. The iOS target has been renamed from arm-apple-ios to arm-apple-darwin. A complete list of the targets we accept now: arm-apple-darwin arm-linux-androideabi arm-unknown-linux-gnueabi arm-unknown-linux-gnueabihf i686-apple-darwin i686-pc-windows-gnu i686-unknown-freebsd i686-unknown-linux-gnu mips-unknown-linux-gnu mipsel-unknown-linux-gnu x86_64-apple-darwin x86_64-unknown-freebsd x86_64-unknown-linux-gnu x86_64-pc-windows-gnu Closes #16093 [breaking-change]

-Z linker-flavor This patch adds a `-Z linker-flavor` flag to rustc which can be used to invoke the linker using a different interface. For example, by default rustc assumes that all the Linux targets will be linked using GCC. This makes it impossible to use LLD as a linker using just `-C linker=ld.lld` because that will invoke LLD with invalid command line arguments. (e.g. rustc will pass -Wl,--gc-sections to LLD but LLD doesn't understand that; --gc-sections would be the right argument) With this patch one can pass `-Z linker-flavor=ld` to rustc to invoke the linker using a LD-like interface. This way, `rustc -C linker=ld.lld -Z linker-flavor=ld` will invoke LLD with the right arguments. `-Z linker-flavor` accepts 4 different arguments: `em` (emcc), `ld`, `gcc`, `msvc` (link.exe). `em`, `gnu` and `msvc` cover all the existing linker interfaces. `ld` is a new flavor for interfacing GNU's ld and LLD. This patch also changes target specifications. `linker-flavor` is now a mandatory field that specifies the *default* linker flavor that the target will use. This change also makes the linker interface *explicit*; before, it used to be derived from other fields like linker-is-gnu, is-like-msvc, is-like-emscripten, etc. Another change to target specifications is that the fields `pre-link-args`, `post-link-args` and `late-link-args` now expect a map from flavor to linker arguments. ``` diff - "pre-link-args": ["-Wl,--as-needed", "-Wl,-z,-noexecstack"], + "pre-link-args": { + "gcc": ["-Wl,--as-needed", "-Wl,-z,-noexecstack"], + "ld": ["--as-needed", "-z,-noexecstack"], + }, ``` [breaking-change] for users of custom targets specifications
