Those are in ld_args now (-Wl,-X,-S,-r,-T,dxe.ld), gcc splits it at the commas.

The assembler is invoked via dxe_cc (gcc -c) instead.

Getting multiple input sections sounds like some problem with the linker script.
Do you have an open-source project for me to test on?  I'll admit that I've
never used DXE libraries before...

I tried it with a basic hello-world that uses std::vector, and got a long list
of unresolved references.  But I get the same list with an unpatched dxe3gen.
It does make a .dxe file with -U.
