- Mangles (T0, T1) as tuple<T0, T1>, possibly unblocking rust-lang#70052 "Update hashbrown to 0.8.0" - Prettifies Rust tuples similar to VS2017's std::tuple - Improves debuginfo test coverage
PDB debug information doesn't appear to be emitted for basic types. By defining u32 as a typedef for unsigned __int32 when targeting MSVC, we allow CDB and other debuggers to recognize "u32" as a type/expression. This in turn unblocks rust-lang#70052 "Update hashbrown to 0.8.0" by allowing $T1 ..= $T3 to resolve, which would otherwise fail to resolve when builtin types fail to parse.
This patch avoids undefined behavior by linking different object files. Also this would it could be propagated properly to LTO. See https://reviews.llvm.org/D52322 and https://reviews.llvm.org/D52323.
When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system. However, since we pass cmake defines to set the compiler and target, LLVM still compiles these tools for the target system, rather than the host. The tools then fail to execute during the LLVM build. This change sets defines for the tools that need to run on the host (llvm-nm, llvm-tablegen, and llvm-config), so that the LLVM build does not attempt to build them, and instead relies on the tools already built. If compiling with clang-cl, this change also adds the `--target` option to specify the target triple. MSVC compilers do not require this, since there is a separate compiler binary for cross-compilation.
As of rust-lang#73564, the --eh-frame-hdr flag is unconditionally passed to linkers on many platforms. The illumos link editor does not currently support this flag. The linker machinery in the Rust toolchain currently seems to use the (potentially cross-compiled) target to choose linker flags, rather than looking at what might be running on the build system. Disabling the flag for all illumos/Solaris targets seems like the best we can do for now without more serious surgery.
Use `matches!` instead of old `if let`
Stabilize `transmute` in constants and statics but not const fn cc rust-lang#53605 (leaving issue open so we can add `transmute` to `const fn` later) Previous attempt: rust-lang#64011 r? @RalfJung cc @rust-lang/wg-const-eval
…manieu debuginfo: Mangle tuples to be natvis friendly, typedef basic types These changes are meant to unblock rust-lang#70052 "Update hashbrown to 0.8.0" by allowing the use of `tuple<u64, u64>` as a .natvis expression in MSVC style debuggers (MSVC, WinDbg, CDB, etc.) * f8eb81b does the actual mangling of `(u64, u64)` -> `tuple<u64, 64>` * 24a728a allows `u64` to resolve (fixing `$T1` / `$T2` when used to visualize `HashMap<u64, u64, ...>`)
Add support for storing code model to LLVM module IR This patch avoids undefined behavior by linking different object files. Also this would it could be propagated properly to LTO. See https://reviews.llvm.org/D52322 and https://reviews.llvm.org/D52323.
Fix cross compilation of LLVM to aarch64 Windows targets When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system.

…s, r=petrochenkov Add a help to use `in_band_lifetimes` in nightly Fixes rust-lang#73775
Reword incorrect `self` token suggestion
Minor refactor for rustc_resolve diagnostics match Use `matches!` instead of old `if let`
Fix rust-lang#74081 and add the test case from rust-lang#74236
update miri This incorporates rust-lang/miri#1474. [Last time](rust-lang#74146) that change caused trouble but I fixed xargo since then and [now it should work](rust-lang#74146 (comment)). Cc @rust-lang/miri r? @ghost
