rustc: Implement custom panic runtimes This commit is an implementation of [RFC 1513] which allows applications to alter the behavior of panics at compile time. A new compiler flag, `-C panic`, is added and accepts the values `unwind` or `panic`, with the default being `unwind`. This model affects how code is generated for the local crate, skipping generation of landing pads with `-C panic=abort`. [RFC 1513]: https://github.com/rust-lang/rfcs/blob/master/text/1513-less-unwinding.md Panic implementations are then provided by crates tagged with `#![panic_runtime]` and lazily required by crates with `#![needs_panic_runtime]`. The panic strategy (`-C panic` value) of the panic runtime must match the final product, and if the panic strategy is not `abort` then the entire DAG must have the same panic strategy. With the `-C panic=abort` strategy, users can expect a stable method to disable generation of landing pads, improving optimization in niche scenarios, decreasing compile time, and decreasing output binary size. With the `-C panic=unwind` strategy users can expect the existing ability to isolate failure in Rust code from the outside world. Organizationally, this commit dismantles the `sys_common::unwind` module in favor of some bits moving part of it to `libpanic_unwind` and the rest into the `panicking` module in libstd. The custom panic runtime support is pretty similar to the custom allocator support with the only major difference being how the panic runtime is injected (takes the `-C panic` flag into account).

Add a new wasm32-unknown-wasi target This commit adds a new wasm32-based target distributed through rustup, supported in the standard library, and implemented in the compiler. The `wasm32-unknown-wasi` target is intended to be a WebAssembly target which matches the [WASI proposal recently announced.][LINK]. In summary the WASI target is an effort to define a standard set of syscalls for WebAssembly modules, allowing WebAssembly modules to not only be portable across architectures but also be portable across environments implementing this standard set of system calls. The wasi target in libstd is still somewhat bare bones. This PR does not fill out the filesystem, networking, threads, etc. Instead it only provides the most basic of integration with the wasi syscalls, enabling features like: * `Instant::now` and `SystemTime::now` work * `env::args` is hooked up * `env::vars` will look up environment variables * `println!` will print to standard out * `process::{exit, abort}` should be hooked up appropriately None of these APIs can work natively on the `wasm32-unknown-unknown` target, but with the assumption of the WASI set of syscalls we're able to provide implementations of these syscalls that engines can implement. Currently the primary engine implementing wasi is [wasmtime], but more will surely emerge! In terms of future development of libstd, I think this is something we'll probably want to discuss. The purpose of the WASI target is to provide a standardized set of syscalls, but it's *also* to provide a standard C sysroot for compiling C/C++ programs. This means it's intended that functions like `read` and `write` are implemented for this target with a relatively standard definition and implementation. It's unclear, therefore, how we want to expose file descriptors and how we'll want to implement system primitives. For example should `std::fs::File` have a libc-based file descriptor underneath it? The raw wasi file descriptor? We'll see! Currently these details are all intentionally hidden and things we can change over time. A `WasiFd` sample struct was added to the standard library as part of this commit, but it's not currently used. It shows how all the wasi syscalls could be ergonomically bound in Rust, and they offer a possible implementation of primitives like `std::fs::File` if we bind wasi file descriptors exactly. Apart from the standard library, there's also the matter of how this target is integrated with respect to its C standard library. The reference sysroot, for example, provides managment of standard unix file descriptors and also standard APIs like `open` (as opposed to the relative `openat` inspiration for the wasi ssycalls). Currently the standard library relies on the C sysroot symbols for operations such as environment management, process exit, and `read`/`write` of stdio fds. We want these operations in Rust to be interoperable with C if they're used in the same process. Put another way, if Rust and C are linked into the same WebAssembly binary they should work together, but that requires that the same C standard library is used. We also, however, want the `wasm32-unknown-wasi` target to be usable-by-default with the Rust compiler without requiring a separate toolchain to get downloaded and configured. With that in mind, there's two modes of operation for the `wasm32-unknown-wasi` target: 1. By default the C standard library is statically provided inside of `liblibc.rlib` distributed as part of the sysroot. This means that you can `rustc foo.wasm --target wasm32-unknown-unknown` and you're good to go, a fully workable wasi binary pops out. This is incompatible with linking in C code, however, which may be compiled against a different sysroot than the Rust code was previously compiled against. In this mode the default of `rust-lld` is used to link binaries. 2. For linking with C code, the `-C target-feature=-crt-static` flag needs to be passed. This takes inspiration from the musl target for this flag, but the idea is that you're no longer using the provided static C runtime, but rather one will be provided externally. This flag is intended to also get coupled with an external `clang` compiler configured with its own sysroot. Therefore you'll typically use this flag with `-C linker=/path/to/clang-script-wrapper`. Using this mode the Rust code will continue to reference standard C symbols, but the definition will be pulled in by the linker configured. Alright so that's all the current state of this PR. I suspect we'll definitely want to discuss this before landing of course! This PR is coupled with libc changes as well which I'll be posting shortly. [LINK]: [wasmtime]:

Add profiling support, through the rustc -Z profile flag. When -Z profile is passed, the GCDAProfiling LLVM pass is added to the pipeline, which uses debug information to instrument the IR. After compiling with -Z profile, the $(OUT_DIR)/$(CRATE_NAME).gcno file is created, containing initial profiling information. After running the program built, the $(OUT_DIR)/$(CRATE_NAME).gcda file is created, containing branch counters. The created *.gcno and *.gcda files can be processed using the "llvm-cov gcov" and "lcov" tools. The profiling data LLVM generates does not faithfully follow the GCC's format for *.gcno and *.gcda files, and so it will probably not work with other tools (such as gcov itself) that consume these files.

std: Depend on `backtrace` crate from crates.io This commit removes all in-tree support for generating backtraces in favor of depending on the `backtrace` crate on crates.io. This resolves a very longstanding piece of duplication where the standard library has long contained the ability to generate a backtrace on panics, but the code was later extracted and duplicated on crates.io with the `backtrace` crate. Since that fork each implementation has seen various improvements one way or another, but typically `backtrace`-the-crate has lagged behind libstd in one way or another. The goal here is to remove this duplication of a fairly critical piece of code and ensure that there's only one source of truth for generating backtraces between the standard library and the crate on crates.io. Recently I've been working to bring the `backtrace` crate on crates.io up to speed with the support in the standard library which includes: * Support for `StackWalkEx` on MSVC to recover inline frames with debuginfo. * Using `libbacktrace` by default on MinGW targets. * Supporting `libbacktrace` on OSX as an option. * Ensuring all the requisite support in `backtrace`-the-crate compiles with `#![no_std]`. * Updating the `libbacktrace` implementation in `backtrace`-the-crate to initialize the global state with the correct filename where necessary. After reviewing the code in libstd the `backtrace` crate should be at exact feature parity with libstd today. The backtraces generated should have the same symbols and same number of frames in general, and there's not known divergence from libstd currently. Note that one major difference between libstd's backtrace support and the `backtrace` crate is that on OSX the crates.io crate enables the `coresymbolication` feature by default. This feature, however, uses private internal APIs that aren't published for OSX. While they provide more accurate backtraces this isn't appropriate for libstd distributed as a binary, so libstd's dependency on the `backtrace` crate explicitly disables this feature and forces OSX to use `libbacktrace` as a symbolication strategy. The long-term goal of this refactoring is to eventually move us towards a world where we can drop `libbacktrace` entirely and simply use Gimli and the surrounding crates for backtrace support. That's still aways off but hopefully will much more easily enabled by having the source of truth for backtraces live in crates.io! Procedurally if we go forward with this I'd like to transfer the `backtrace-rs` crate to the rust-lang GitHub organization as well, but I figured I'd hold off on that until we get closer to merging.

std: Remove `rand` crate and module This commit removes the `rand` crate from the standard library facade as well as the `__rand` module in the standard library. Neither of these were used in any meaningful way in the standard library itself. The only need for randomness in libstd is to initialize the thread-local keys of a `HashMap`, and that unconditionally used `OsRng` defined in the standard library anyway. The cruft of the `rand` crate and the extra `rand` support in the standard library makes libstd slightly more difficult to port to new platforms, namely WebAssembly which doesn't have any randomness at all (without interfacing with JS). The purpose of this commit is to clarify and streamline randomness in libstd, focusing on how it's only required in one location, hashmap seeds. Note that the `rand` crate out of tree has almost always been a drop-in replacement for the `rand` crate in-tree, so any usage (accidental or purposeful) of the crate in-tree should switch to the `rand` crate on crates.io. This then also has the further benefit of avoiding duplication (mostly) between the two crates!

Support AddressSanitizer and ThreadSanitizer on x86_64-apple-darwin. ASan and TSan are supported on macOS, and this commit enables their support. The sanitizers are always built as *.dylib on Apple platforms, so they cannot be statically linked into the corresponding `rustc_?san.rlib`. The dylibs are directly copied to `lib/rustlib/x86_64-apple-darwin/lib/` instead. Note, although Xcode also ships with their own copies of ASan/TSan dylibs, we cannot use them due to version mismatch. There is a caveat: the sanitizer libraries are linked as @rpath, so the user needs to additionally pass `-C rpath`: rustc -Z sanitizer=address -C rpath file.rs ^~~~~~~~ Otherwise there will be a runtime error: dyld: Library not loaded: @rpath/libclang_rt.asan_osx_dynamic.dylib Referenced from: /path/to/executable Reason: image not found Abort trap: 6 The next commit includes a temporary change in compiler to force the linker to emit a usable @rpath.

std: Depend directly on crates.io crates Ever since we added a Cargo-based build system for the compiler the standard library has always been a little special, it's never been able to depend on crates.io crates for runtime dependencies. This has been a result of various limitations, namely that Cargo doesn't understand that crates from crates.io depend on libcore, so Cargo tries to build crates before libcore is finished. I had an idea this afternoon, however, which lifts the strategy from #52919 to directly depend on crates.io crates from the standard library. After all is said and done this removes a whopping three submodules that we need to manage! The basic idea here is that for any crate `std` depends on it adds an *optional* dependency on an empty crate on crates.io, in this case named `rustc-std-workspace-core`. This crate is overridden via `[patch]` in this repository to point to a local crate we write, and *that* has a `path` dependency on libcore. Note that all `no_std` crates also depend on `compiler_builtins`, but if we're not using submodules we can publish `compiler_builtins` to crates.io and all crates can depend on it anyway! The basic strategy then looks like: * The standard library (or some transitive dep) decides to depend on a crate `foo`. * The standard library adds ```toml [dependencies] foo = { version = "0.1", features = ['rustc-dep-of-std'] } ``` * The crate `foo` has an optional dependency on `rustc-std-workspace-core` * The crate `foo` has an optional dependency on `compiler_builtins` * The crate `foo` has a feature `rustc-dep-of-std` which activates these crates and any other necessary infrastructure in the crate. A sample commit for `dlmalloc` [turns out to be quite simple][commit]. After that all `no_std` crates should largely build "as is" and still be publishable on crates.io! Notably they should be able to continue to use stable Rust if necessary, since the `rename-dependency` feature of Cargo is soon stabilizing. As a proof of concept, this commit removes the `dlmalloc`, `libcompiler_builtins`, and `libc` submodules from this repository. Long thorns in our side these are now gone for good and we can directly depend on crates.io! It's hoped that in the long term we can bring in other crates as necessary, but for now this is largely intended to simply make it easier to manage these crates and remove submodules. This should be a transparent non-breaking change for all users, but one possible stickler is that this almost for sure breaks out-of-tree `std`-building tools like `xargo` and `cargo-xbuild`. I think it should be relatively easy to get them working, however, as all that's needed is an entry in the `[patch]` section used to build the standard library. Hopefully we can work with these tools to solve this problem! [commit]: https://github.com/alexcrichton/dlmalloc-rs/commit/28ee12db813a3b650a7c25d1c36d2c17dcb88ae3

std: Implement TLS for wasm32-unknown-unknown This adds an implementation of thread local storage for the `wasm32-unknown-unknown` target when the `atomics` feature is implemented. This, however, comes with a notable caveat of that it requires a new feature of the standard library, `wasm-bindgen-threads`, to be enabled. Thread local storage for wasm (when `atomics` are enabled and there's actually more than one thread) is powered by the assumption that an external entity can fill in some information for us. It's not currently clear who will fill in this information nor whose responsibility it should be long-term. In the meantime there's a strategy being gamed out in the `wasm-bindgen` project specifically, and the hope is that we can continue to test and iterate on the standard library without committing to a particular strategy yet. As to the details of `wasm-bindgen`'s strategy, LLVM doesn't currently have the ability to emit custom `global` values (thread locals in a `WebAssembly.Module`) so we leverage the `wasm-bindgen` CLI tool to do it for us. To that end we have a few intrinsics, assuming two global values: * `__wbindgen_current_id` - gets the current thread id as a 32-bit integer. It's `wasm-bindgen`'s responsibility to initialize this per-thread and then inform libstd of the id. Currently `wasm-bindgen` performs this initialization as part of the `start` function. * `__wbindgen_tcb_{get,set}` - in addition to a thread id it's assumed that there's a global available for simply storing a pointer's worth of information (a thread control block, which currently only contains thread local storage). This would ideally be a native `global` injected by LLVM, but we don't have a great way to support that right now. To reiterate, this is all intended to be unstable and purely intended for testing out Rust on the web with threads. The story is very likely to change in the future and we want to make sure that we're able to do that!

Add libstd and libcore Cargo features "panic_immediate_abort" It stop asserts and panics from libstd to automatically include string output and formatting code. Use case: developing static executables smaller than 50 kilobytes, where usual formatting code is excessive while keeping debuggability in debug mode. May resolve #54981.
