* 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.

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.
