Diana Picus 0ad051b5fc [flang] Check there's no dependency on C++ libs. NFC ... Add a test to make sure the flang runtime doesn't pull in the C++ runtime libraries. This is achieved by adding a C file that calls some functions from the runtime (currently only CpuTime, but we should probably add anything complicated enough, e.g. IO-related things). We force the C compiler to use -std=c90 to make sure it's really in C mode (we don't really care which version of the standard, this one is probably more widely available). We only enable this test if CMAKE_C_COMPILER is set to something (which is probably always true in practice). This is a recommit of 7ddbf26, with 2 fixes: * Replace C++ comments with C comments * Only enable the test if libFortranRuntime.a exists (this might not be the case if e.g. BUILD_SHARED_LIBS=On) Differential Revision: https://reviews.llvm.org/D104290		2021-06-16 11:38:25 +00:00
