* 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
* [DynamicLibrary] Fix build on musl libcKeno Fischer2017-10-261-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: On musl libc, stdin/out/err are defined as `FILE* const` globals, and their address is not implicitly convertible to void *, or at least gcc 6 doesn't allow it, giving errors like: ``` error: cannot initialize return object of type 'void *' with an rvalue of type 'FILE *const *' (aka '_IO_FILE *const *') EXPLICIT_SYMBOL(stderr); ^~~~~~~~~~~~~~~~~~~~~~~ ``` Add an explicit cast to fix that problem.

* Allow clients to specify search order of DynamicLibraries.Frederich Munch2017-07-121-0/+3
| | | | | | | | | | | | | | Summary: Different JITs and other clients of LLVM may have different needs in how symbol resolution should occur.

* Close DynamicLibraries in reverse order they were opened.Frederich Munch2017-06-051-1/+2
| | | | | | | | | | | | | | Summary: Matches C++ destruction ordering better and fixes possible problems of loaded libraries having inter-dependencies.

* Fix building DynamicLibrary.cpp with musl libcDimitry Andric2017-06-051-2/+2
| | | | | | | | | | | | | | | | | | | | | Summary: The workaround added in rL301240 for stderr/out/in symbols being both macros and globals is only necessary for glibc, and it does not compile with musl libc. Alpine Linux has had the following fix for it: https://git.alpinelinux.org/cgit/aports/plain/main/llvm4/llvm-fix-DynamicLibrary-to-build-with-musl-libc.patch Adapt the fix in our DynamicLibrary.inc for Unix.

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.
