[PATCH] [mc-coff] Forward Linker Option flags into the .drectve section

[Rafael Espíndola]

>> Is the format documented somewhere we could link to?

> The .drectve section, which we already use for dllexported symbols, is
> part of the PE-COFF spec:

> A .drectve section consists of a string of text that can be encoded as ANSI or

> interpreted as ANSI.
> The directive string is a series of linker options that are separated

> option contains a hyphen, the option name, and any appropriate attribute. If
> an option contains spaces, the option must be enclosed in quotes. The .drectve
> section must not have relocations or line numbers.

The best url I could find is

so I guess just saying "the pe-coff spec" is fine. I tried looking at
it last night but searched for ".directive" instead of ".drectve" :-(

Thanks!
