This used to be necessary for a correct linker order, but ever since the
introduction of symbols.o adding the symbols in question to symbols.o
would work just as well. We do still add dependencies on the panic runtime
to the local crate, but not for #![needs_panic_runtime] crates.
This also removes the runtime-depends-on-needs-runtime test.
inject_dependency_if used to emit this error, but with symbols.o it is
no longer important that there is no dependency and in fact it may be
nice to have panic_abort and panic_unwind directly depend on libstd in
the future for calling std::process::abort().
While cg_llvm is very lax about mismatched function signatures, cg_clif
will crash when there is any mismatch. It could be turned into an error,
but without Cranelift changes can't just be ignored.
compiletest: Make `SUGGESTION` annotations viral
If one of them is expected in a test file, then others should be annotated as well, in the same way as with `HELP`s and `NOTE`s.
This doesn't require much of an additional annotation burden, but simplifies the rules.
r? ```@jieyouxu```
* The WASI targets deal with the `main` symbol a bit differently than
native so some `codegen` and `assembly` tests have been ignored.
* All `ignore-emscripten` directives have been updated to
`ignore-wasm32` to be more clear that all wasm targets are ignored and
it's not just Emscripten.
* Most `ignore-wasm32-bare` directives are now gone.
* Some ignore directives for wasm were switched to `needs-unwind`
instead.
* Many `ignore-wasm32*` directives are removed as the tests work with
WASI as opposed to `wasm32-unknown-unknown`.
