Rename `llvm::Bool` aliases to standard const case

2025-08-24T13:09:54+00:00

This avoids the need for `#![allow(non_upper_case_globals)]`.

Use `LLVMDIBuilderCreateNameSpace`

2025-02-01T03:14:39+00:00

Use a type-safe helper to cast `&str` and `&[u8]` to `*const c_char`

2024-10-28T10:31:32+00:00

Reformat using the new identifier sorting from rustfmt

2024-09-22T23:11:29+00:00

Remove a low-value local variable.

2024-09-19T10:10:42+00:00

Add `warn(unreachable_pub)` to `rustc_codegen_llvm`.

2024-08-15T22:46:57+00:00

Reformat `use` declarations.

2024-07-28T22:26:52+00:00

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

Set capacity of the string passed to `push_item_name`.

2023-06-29T01:46:25+00:00

Other callsites already do this, but these two were missed. This avoids some allocations.

Remove `in_band_lifetimes` from `rustc_codegen_llvm`

See #91867 for more information.

Improve debug symbol names to avoid ambiguity and work better with MSVC's debugger

2021-06-30T18:10:29+00:00

There are several cases where names of types and functions in the debug info are either ambiguous, or not helpful, such as including ambiguous placeholders (e.g., `{{impl}}`, `{{closure}}` or `dyn _'`) or dropping qualifications (e.g., for dynamic types). Instead, each debug symbol name should be unique and useful: * Include disambiguators for anonymous `DefPathDataName` (closures and generators), and unify their formatting when used as a path-qualifier vs item being qualified. * Qualify the principal trait for dynamic types. * If there is no principal trait for a dynamic type, emit all other traits instead. * Respect the `qualified` argument when emitting ref and pointer types. * For implementations, emit the disambiguator. * Print const generics when emitting generic parameters or arguments. Additionally, when targeting MSVC, its debugger treats many command arguments as C++ expressions, even when the argument is defined to be a symbol name. As such names in the debug info need to be more C++-like to be parsed correctly: * Avoid characters with special meaning (`#`, `[`, `"`, `+`). * Never start a name with `<` or `{` as this is treated as an operator. * `>>` is always treated as a right-shift, even when parsing generic arguments (so add a space to avoid this). * Emit function declarations using C/C++ style syntax (e.g., leading return type). * Emit arrays as a synthetic `array$` type. * Include a `$` in all synthetic types as this is a legal character for C++, but not Rust (thus we avoid collisions with user types).
