Everything is in the title. -S (do not assemble) is not supported by the frontend yet.

When -S is passed:

  • do not call the link command ad the end (driver.compileOnly = true)
  • the generated file (relo) ends with .s and not with .o
  • do not remove it

I have also added it in the help displayed by -h.

I don't really know what to test in the associated unit test, since the generated assembly code depends on the backed compiler we are using...

The idea seems solid to me, but I am also unsure how best to test this. Also, did you clang-format the code before uploading the patch?

yes, I clang-format-ed the code, and I think this is what explains the modification line 620 for example.
