test/Driver/linker-flags.f90

! Verify that the Fortran runtime libraries are present in the linker
! invocation. These libraries are added on top of other standard runtime
! libraries that the Clang driver will include.

! RUN: %flang -### -flang-experimental-exec -target ppc64le-linux-gnu %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,GNU
! RUN: %flang -### -flang-experimental-exec -target aarch64-apple-darwin %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,DARWIN
! RUN: %flang -### -flang-experimental-exec -target x86_64-windows-gnu %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,MINGW

! NOTE: Clang's driver library, clangDriver, usually adds 'libcmt' and
!       'oldnames' on Windows, but they are not needed when compiling
!       Fortran code and they might bring in additional dependencies.
!       Make sure they're not added.
! RUN: %flang -### -flang-experimental-exec -target aarch64-windows-msvc %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,MSVC --implicit-check-not libcmt --implicit-check-not oldnames

! Linker invocation to generate the executable
! NOTE: Since we are cross-compiling, the host toolchain executables may
!       run on any other platform, such as Windows that use a .exe
!       suffix. Clang's driver will try to resolve the path to the ld
!       executable and may find the GNU linker from MinGW or Cygwin.
