...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 modifi...
