CMakeLists.txt	[LLDB] Add setting for native PDB reader (#151490) Initially suggested in https://github.com/llvm/llvm-project/pull/149305#issuecomment-3113413702 - this PR adds the setting plugin.symbol-file.pdb.use-native-reader. It doesn't remove support for LLDB_USE_NATIVE_PDB_READER to allow some backwards compatibility. This was the suggested way to use the native reader - changing that would mean users who set this, now use the DIA reader. The setting has priority over the environment variable, though. If the default gets flipped on Windows, the environment variable could probably be removed as well. This would make it possible to test both native PDB and DIA PDB in the API tests (see linked PR).	1 年前
PDBASTParser.cpp	[clang] Improve nested name specifier AST representation (#147835) This is a major change on how we represent nested name qualifications in the AST. * The nested name specifier itself and how it's stored is changed. The prefixes for types are handled within the type hierarchy, which makes canonicalization for them super cheap, no memory allocation required. Also translating a type into nested name specifier form becomes a no-op. An identifier is stored as a DependentNameType. The nested name specifier gains a lightweight handle class, to be used instead of passing around pointers, which is similar to what is implemented for TemplateName. There is still one free bit available, and this handle can be used within a PointerUnion and PointerIntPair, which should keep bit-packing aficionados happy. * The ElaboratedType node is removed, all type nodes in which it could previously apply to can now store the elaborated keyword and name qualifier, tail allocating when present. * TagTypes can now point to the exact declaration found when producing these, as opposed to the previous situation of there only existing one TagType per entity. This increases the amount of type sugar retained, and can have several applications, for example in tracking module ownership, and other tools which care about source file origins, such as IWYU. These TagTypes are lazily allocated, in order to limit the increase in AST size. This patch offers a great performance benefit. It greatly improves compilation time for [stdexec](https://github.com/NVIDIA/stdexec). For one datapoint, for test_on2.cpp in that project, which is the slowest compiling test, this patch improves -c compilation time by about 7.2%, with the -fsyntax-only improvement being at ~12%. This has great results on compile-time-tracker as well:  This patch also further enables other optimziations in the future, and will reduce the performance impact of template specialization resugaring when that lands. It has some other miscelaneous drive-by fixes. About the review: Yes the patch is huge, sorry about that. Part of the reason is that I started by the nested name specifier part, before the ElaboratedType part, but that had a huge performance downside, as ElaboratedType is a big performance hog. I didn't have the steam to go back and change the patch after the fact. There is also a lot of internal API changes, and it made sense to remove ElaboratedType in one go, versus removing it from one type at a time, as that would present much more churn to the users. Also, the nested name specifier having a different API avoids missing changes related to how prefixes work now, which could make existing code compile but not work. How to review: The important changes are all in clang/include/clang/AST and clang/lib/AST, with also important changes in clang/lib/Sema/TreeTransform.h. The rest and bulk of the changes are mostly consequences of the changes in API. PS: TagType::getDecl is renamed to getOriginalDecl in this patch, just for easier to rebasing. I plan to rename it back after this lands.

PDBASTParser.h	[lldb] Update header guards to be consistent and compliant with LLVM (NFC) LLDB has a few different styles of header guards and they're not very consistent because things get moved around or copy/pasted. This patch unifies the header guards across LLDB and converts everything to match LLVM's style. Differential revision: https://reviews.llvm.org/D74743	6 年前
PDBLocationToDWARFExpression.cpp	[lldb] Eliminate namespace lldb_private::dwarf (NFC) (#150073) Eliminate the lldb_private::dwarf namespace, in favor of using llvm::dwarf directly. The latter is shorter, and this avoids ambiguity in the ABI plugins that define a dwarf namespace inside an anonymous namespace.	1 年前

SymbolFilePDB.cpp	[LLDB] Use native PDB reader by default (#165363) All PDB tests now pass when compiled without DIA on Windows, so they pass with the native reader. With this PR, the default reader changes to the native reader. The plan is to eventually remove the DIA reader (see https://discourse.llvm.org/t/rfc-removing-the-dia-pdb-plugin-from-lldb/87827 and #114906). For now, DIA can be used by setting plugin.symbol-file.pdb.reader to dia or by setting LLDB_USE_NATIVE_PDB_READER=0 (mostly undocumented, but used in tests).	9 个月前
SymbolFilePDB.h	[lldb][TypeSystem] Enable colored AST dump (#86159) This patch causes the various AST dump commands (target modules dump ast/target dump typesystem) to be color-highlighted. I added a bool show_color parameter to SymbolFile::DumpClangAST and TypeSystem::Dump. In TypeSystemClang I temporarily sets the getShowColors flag on the owned Clang AST (using an RAII helper) for the duration of the AST dump. We use Debugger::GetUseColors to decide whether to color the AST dump.	10 个月前
