flang/test/Driver/save-mlir-temps.f90

   1 ! Tests for the `-save-temps` flag. Instead of checking the commands generated
   2 ! by the driver with `-###` (like the save-temps.f90 test does), here we check
   3 ! that the MLIR files are actually produced in the specified location because
   4 ! the driver does not generate specific passes for MLIR. Instead, they are
   5 ! generated during code generation as additional outputs.
   6
   7 ! As `flang` does not implement `-fc1as` (i.e. a driver for the integrated
   8 ! assembler), we need to use `-fno-integrated-as` here.
   9 ! However, calling an external assembler on arm64 Macs fails, because it's
  10 ! currently being invoked with the `-Q` flag, that is not supported on arm64.
  11 ! UNSUPPORTED: system-windows, system-darwin
