...to specify a that a global variable should appear before the corresponding function in the object code. An example of a possible implementation of (2) has been recently suggested by Gabor Greif. He proposes adding a "placebefore" attribute to global variables (or, similarly, a "placeafter" attribute for functions). The corresponding example is: @foo_D = common global %struct.Descr zeroinitializer, align 8, placebefore @foo define i32 @foo() nounwind uwtable readnone { ret i32 undef } The questions is whether the LLVM developers are willing to accept such modifica...

The corresponding example is: This is a non-starter for a few reasons, but that doesn't mean that there aren't other reasonable options. I'd really like to see the codegen that you guys are after to try to help come up with another suggestion that...
