* 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. llvm-svn: 351636
* Export the required symbol from DynamicLibraryTestsRoger Ferrer Ibanez2017-06-121-0/+2
| | | | | | | | | | | | | | | | | Running unittests/Support/DynamicLibrary/DynamicLibraryTests fails when LLVM is configured with -DLLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON, because the test's version script only contains symbols extracted from the static libraries, that the test links with, but not those from the main object/executable itself. The patch moves the one symbol, needed by the test, to a static library. Fixes https://bugs.llvm.org/show_bug.cgi?id=32893 Patch by Momchil Velikov.

* Close DynamicLibraries in reverse order they were opened.Frederich Munch2017-06-051-0/+13
| | | | | | | | | | | | | | Summary: Matches C++ destruction ordering better and fixes possible problems of loaded libraries having inter-dependencies.

* Refactor DynamicLibrary so searching for a symbol will have a defined order andFrederich Munch2017-04-271-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | libraries are properly unloaded when llvm_shutdown is called. Summary: This was mostly affecting usage of the JIT, where storing the library handles in a set made iteration unordered/undefined. This lead to disagreement between the JIT and native code as to what the address and implementation of particularly on Windows with stdlib functions: JIT: putenv_s("TEST", "VALUE") // called msvcrt.dll, putenv_s JIT: getenv("TEST") -> "VALUE" // called msvcrt.dll, getenv Native: getenv("TEST") -> NULL // called ucrt.dll, getenv Also fixed is the issue of DynamicLibrary::getPermanentLibrary(0,0) on Windows not giving priority to the process' symbols as it did on Unix.
