* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-091-8/+8
| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

Original commit message: [modules] Rework serialized DeclContext lookup table management. Instead of walking the loaded ModuleFiles looking for lookup tables for the context, store them all in one place, and merge them together if we find we have too many (currently, more than 4). If we do merge, include the merged form in our serialized lookup table, so that downstream readers never need to look at our imports' tables.

* Objective-C: Serialize "more than one decl" state of ObjCMethodList.Nico Weber2014-12-271-0/+2
| | | | | | | | | | | | | | | | | | This fixes PR21587, what r221933 fixed for regular programs is now also fixed for decls coming from PCH files. Use another bit from the count/bits uint16_t for storing the "more than one decl" bit. This reduces the number of bits for the count from 14 to 13. The selector with the most overloads in Cocoa.h has ~55 overloads, so 13 bits should still be plenty. Since this changes the meaning of a serialized bit pattern, also increase clang::serialization::VERSION_MAJOR. Storing the "more than one decl" state of only the first overload isn't quite correct, but Sema::AreMultipleMethodsInGlobalPool() currently only looks at the state of the first overload so it's good enough for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@224892 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | the root of the module and use paths relative to that directory wherever possible. This is a step towards allowing explicit modules to be relocated without being rebuilt, which is important for some kinds of distributed builds, for good paths in diagnostics, and for appropriate .d output. This is a recommit of r223443, reverted in r223465; when joining together imported file paths, we now use the system's separator rather than always using '/'. This avoids path mismatches between the original module build and the module user on Windows (at least, in some cases). A more comprehensive fix will follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@223539 91177308-0d34-0410-b5e6-96231b3b80d8

* OnDiskHashTable: Make the iterable version separate.Justin Bogner2014-04-141-1/+1
| | | | | | | | | | | | | | | Currently the on disk hash table's key_iterator and data_iterator make the assumption that the table data starts exactly four bytes after the base of the table. This happens to be true for all of the tables we currently iterate over, but not for all of the OnDiskHashTables we currently use. For example, key_ and data_iterator would iterate over meaningless data if they were used on the hash tables in PTHLexer. We make the API safer by breaking this into two types. One doesn't have the iterators, and the other must be told where the payload starts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@206189 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | 2 methods (with a particular selector) inside categories. This is done by extending ObjCMethodList (which is only used by the global method pool) to have 2 extra bits of information. We will later take advantage of this info in global method pool for the overridden methods calculation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179652 91177308-0d34-0410-b5e6-96231b3b80d8
* [PCH] For HeaderFileInfoTrait, hash the key using size & time of the file.Argyrios Kyrtzidis2013-03-061-10/+14
| | | | | | | | | | | | Previously the hash would be the filename portion of the path, which could be different for a filename with different case or a symbolic link with a different name completely. This did not actually create any issue so far because by validating all headers in the PCH we created uniqued FileEntries based on inodes, so an #include of a symbolic link (refering to a file from the PCH) would end up with a FileEntry with filename same as the one recorded in the PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176566 91177308-0d34-0410-b5e6-96231b3b80d8
