Fix failed tests related to pointer printing when using GDB 10

2021-04-27T15:07:36+00:00

As mentioned in #79009, there are four failed debuginfo test cases when using GDB 10. This commit fixes two of them, which fail because GDB 10 won't print pointers as string anymore. We can use `printf` as a workaround. It should work regardless of the version of GDB. Refer this [comment] for more details.

Fix closed over variables not available in debuginfo for Windows MSVC

2021-04-08T18:08:56+00:00

The issue was that the resulting debuginfo was too complex for LLVM to translate into CodeView records correctly. As a result, it simply ignored the debuginfo which meant Windows debuggers could not display any closed over variables when stepping inside a closure. This fixes that by spilling additional variables to the stack so that the resulting debuginfo is simple (just `*my_variable.dbg.spill`) and LLVM can generate the correct CV records.

Remove redundant `ignore-tidy-linelength` annotations

2021-04-03T20:30:20+00:00

This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed.

Improvements to NatVis support

2020-12-28T20:14:49+00:00

NatVis files describe how to display types in some Windows debuggers, such as Visual Studio, WinDbg, and VS Code. This commit makes several improvements: * Adds visualizers for Rc, Weak, and Arc. * Changes [size] to [len], for consistency with the Rust API. Visualizers often use [size] to mirror the size() method on C++ STL collections. * Several visualizers used the PVOID and ULONG typedefs. These are part of the Windows API; they are not guaranteed to always be defined in a pure Rust DLL/EXE. I converted PVOID to `void*` and `ULONG` to `unsigned long`. * Cosmetic change: Removed {} braces around the visualized display for `Option` types. They now display simply as `Some(value)` or `None`, which reflects what is written in source code. * The visualizer for `alloc::string::String` makes assumptions about the layout of `String` (it casts `String*` to another type), rather than using symbolic expressions. This commit changes the visualizer so that it simply uses symbolic expressions to access the string data and string length.

BTreeMap: replace Root with NodeRef `NodeRef` already exists as a representation of root nodes, and it makes more sense to alias `Root` to that than to reuse the space-efficient `BoxedNode` that is oblivious to height, where height is required. r? `@Mark-Simulacrum`
