Extended Description

LLVM Assumes that COFF linkonce sections are named .

$linkonce. This is only true on MinGW and Cygwin. Native Windows tools use just .
.

The flags are also incorrect. link.exe warns about it.

I just noticed this bug while inspecting for differences between Clang and cl object files.

What should we do about this?

Rafael fixed this back in r195798. We even use simple section names (.text) for Cygwin and mingw, which should be ABI compatible.
