2022-05-10[Frontend] Flip default of CreateInvocationOptions::ProbePrecompiled to falseSam McCall1-0/+1
This is generally a better default for tools other than the compiler, which shouldn't assume a PCH file on disk is something they can consume. Preserve the old behavior in places associated with libclang/c-index-test (including ASTUnit) as there are tests relying on it and most important consumers are out-of-tree. It's unclear whether the tests are specifically trying to test this functionality, and what the downstream implications of removing it are. Hopefully someone more familiar can clean this up in future. Differential Revision: https://reviews.llvm.org/D125149

2022-01-16[cmake] Use `GNUInstallDirs` to support custom installation dirs.John Ericson1-1/+1
This is the original patch in my GNUInstallDirs series, now last to merge as the final piece! It arose as a new draft of D28234. I initially did the unorthodox thing of pushing to that when I wasn't the original author, but since I ended up - Using `GNUInstallDirs`, rather than mimicking it, as the original author was hesitant to do but others requested. - Converting all the packages, not just LLVM, effecting many more projects than LLVM itself. I figured it was time to make a new revision. I have used this patch series (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS), which was merged last spring (2021). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful. --- As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. Variables like `COMPILER_RT_INSTALL_PATH` have already been dealt with. Variables like `LLVM_LIBDIR_SUFFIX` however, will require further work, so that we may use `CMAKE_INSTALL_LIBDIR`. These remaining items will be addressed in further patches. What is here is now rote and so we should get it out of the way before dealing more intricately with the remainder.

2021-09-25[CMake] Consistently use the LibXml2::LibXml2 target instead of ↵Markus Böck1-6/+1
LIBXML2_LIBRARIES Linking against the LibXml2::LibXml2 target has the advantage of not only importing the library, but also adding the include path as well as any definitions the library requires. In case of a static build of libxml2, eg. a define is set on Windows to remove any DLL imports and export. LLVM already makes use of the target, but c-index-test and lldb were still linking against the library only. The workaround for Mac OS-X that I removed seems to have also been made redundant since https://reviews.llvm.org/D84563 I believe Differential Revision: https://reviews.llvm.org/D109975
2021-04-06[index] Improve macro indexing supportBen Langmuir1-2/+8
The major change here is to index macro occurrences in more places than before, specifically * In non-expansion references such as `#if`, `#ifdef`, etc. * When the macro is a reference to a builtin macro such as __LINE__. * When using the preprocessor state instead of callbacks, we now include all definition locations and undefinitions instead of just the latest one (which may also have had the wrong location previously). * When indexing an existing module file (.pcm), we now include module macros, and we no longer report unrelated preprocessor macros during indexing the module, which could have caused duplication. Additionally, we now correctly obey the system symbol filter for macros, so by default in system headers only definition/undefinition occurrences are reported, but it can be configured to report references as well if desired. Extends FileIndexRecord to support occurrences of macros. Since the design of this type is to keep a single list of entities organized by source location, we incorporate macros into the existing DeclOccurrence struct.

2021-01-21[ASTReader] Allow controlling separately whether validation should be ↵Argyrios Kyrtzidis2-2/+40
disabled for a PCH vs a module file This addresses an issue with how the PCH preable works, specifically: 1. When using a PCH/preamble the module hash changes and a different cache directory is used 2. When the preamble is used, PCH & PCM validation is disabled. Due to combination of #1 and #2, reparsing with preamble enabled can end up loading a stale module file before a header change and using it without updating it because validation is disabled and it doesn’t check that the header has changed and the module file is out-of-date. rdar://72611253 Differential Revision: https://reviews.llvm.org/D95159

D54996 Changed the behaviour of clang_Cursor_isAnonymous, but there is no alternative available to get the old behaviour in some cases, which is essential for determining if a record is syntactically accessible, e.g. struct { int x; int y; } foo; struct { struct { int x; int y; }; } bar; void fun(struct { int x; int y; } *param); The only 'anonymous' struct here is the one nested in bar, since there is no way to reference the struct itself, only the fields within. Though the anonymity applies to the instance itself, not the type. To avoid confusion, I have added a new function called clang_Cursor_isAnonymousRecordDecl which has the old behaviour of clang_Cursor_isAnonymous (and updated the doc for the latter as well, which was seemingly forgotten).
