fix dwarf debuginfo being used in addition to CodeView on windows

2022-07-14T18:41:55+00:00

Fixes the debuginfo size increase regression introduced by the DWARF5 support.

Rename `debugging_opts` to `unstable_opts`

2022-07-13T22:47:06+00:00

This is no longer used only for debugging options (e.g. `-Zoutput-width`, `-Zallow-features`). Rename it to be more clear.

Implement support for DWARF version 5.

2022-07-08T18:31:08+00:00

DWARF version 5 brings a number of improvements over version 4. Quoting from the announcement [1]: > Version 5 incorporates improvements in many areas: better data compression, > separation of debugging data from executable files, improved description of > macros and source files, faster searching for symbols, improved debugging > optimized code, as well as numerous improvements in functionality and > performance. On platforms where DWARF version 5 is supported (Linux, primarily), this commit adds support for it behind a new `-Z dwarf-version=5` flag. [1]: https://dwarfstd.org/Public_Review.php

Update TypeVisitor paths

2022-07-06T05:41:53+00:00

Move/rename `lazy::{OnceCell, Lazy}` to `cell::{OnceCell, LazyCell}`

2022-06-16T15:53:59+00:00

Properly apply path prefix remapping paths emitted into debuginfo.

not need `Option` for `dbg_scope`

debuginfo: Refactor debuginfo generation for types

2022-03-14T15:49:06+00:00

This commit - changes names to use di_node instead of metadata - uniformly names all functions that build new debuginfo nodes build_xyz_di_node - renames CrateDebugContext to CodegenUnitDebugContext (which is more accurate) - moves TypeMap and functions that work directly work with it to a new type_map module - moves and reimplements enum related builder functions to a new enums module - splits enum debuginfo building for the native and cpp-like cases, since they are mostly separate - uses SmallVec instead of Vec in many places - removes the old infrastructure for dealing with recursion cycles (create_and_register_recursive_type_forward_declaration(), RecursiveTypeDescription, set_members_of_composite_type(), MemberDescription, MemberDescriptionFactory, prepare_xyz_metadata(), etc) - adds type_map::build_type_with_children() as a replacement for dealing with recursion cycles - adds many (doc-)comments explaining what's going on - changes cpp-like naming for C-Style enums so they don't get a enum$<...> name (because the NatVis visualizer does not apply to them) - fixes detection of what is a C-style enum because some enums where classified as C-style even though they have fields - changes the position of discriminant debuginfo node so it is consistently nested inside the top-level union instead of, sometimes, next to it
