[llvm-debuginfo-analyzer] Fix ODR violation in llvm::logicalview::LVObject (#140265)
Some data members are only part of a class definition in a Debug build,
e.g. `LVObject::ID`. If `debuginfologicalview` is used as a library,
`NDEBUG` cannot be used for this purpose, as this PP macro may have a
different definition in a downstream project, which in turn triggers an
ODR violation. Fix it by
- Making `LVObject::ID` an unconditional data member.
- Making `LVObject::dump()` non-virtual. Rationale: `virtual` is not
needed (and it calls `print()`, which is virtual anyway).

Fixes #139098.

[llvm-debuginfo-analyzer] Add support for parsing DWARF / CodeView SourceLanguage (#137223)
This pull request adds support for parsing the source language in both
DWARF and CodeView. Specifically,

- The `LVSourceLanguage` class is introduced to represent any supported
language by any of the debug info representations.

- Update `LVDWARFReader.cpp` and `LVCodeViewVisitor.cpp` to parse the
source language where it applies. Added a new `=Language` attribute;
`getAttributeLanguage()` is internally used to control whether this
information is being printed.

[llvm-debuginfo-analyzer] Add support for DWARF DW_AT_byte_size (#139110)
This PR was split from https://github.com/llvm/llvm-project/pull/137228
(which introduced support for `DW_TAG_module` and `DW_AT_byte_size`).

This PR improves `LVDWARFReader` by introducing handling of
`DW_AT_byte_size`. Most DWARF emitters include this attribute for types
to specify the size of an entity of the given type.

[llvm] Use llvm::append_range (NFC) (#133658) 2025-03-30 18:43:02 -07:00

[Analysis, CodeGen, DebugInfo] Use StringRef::operator== instead of StringRef::equals (NFC) (#91304)
I'm planning to remove StringRef::equals in favor of
StringRef::operator==.

- StringRef::operator==/!= outnumber StringRef::equals by a factor of
  53 under llvm/ in terms of their usage.

- The elimination of StringRef::equals brings StringRef closer to
  std::string_view, which has operator== but not equals.

- S == "foo" is more readable than S.equals("foo"), especially for
  !Long.Expression.equals("str") vs Long.Expression != "str".

de1e911f02 [llvm-debuginfo-analyzer] (05/09) - Select elements
The test case 'checkFlexiblePatterns' caused a failure in:

  https://lab.llvm.org/buildbot/#/builders/85/builds/11590
  SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
    runtime error: applying zero offset to null pointer
    llvm/lib/Support/regengine.inc:151:18

The logical view is traversed and for each logical element a
series of match criterias are applied. One of those criterias
is to match its name or type name to a given pattern.

If the logical element does not have a type (for instance a
'namespace') do not try to use its type name, which is a
empty string as the 'matcher' function receives a null pointer.

0332a8e7d6 [llvm-debuginfo-analyzer] (05/09) - Select elements
llvm-debuginfo-analyzer is a command line tool that processes debug
info contained in a binary file and produces a debug information
format agnostic “Logical View”, which is a high-level semantic
representation of the debug info, independent of the low-level
format.

The code has been divided into the following patches:

1) Interval tree
2) Driver and documentation
3) Logical elements
4) Locations and ranges
5) Select elements
6) Warning and internal options
7) Compare elements
8) ELF Reader
9) CodeView Reader
