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