[PATCH] D27276: [ELF, WIP] Allow defined symbols to be assigned from linker script

[Meador Inge via Phabricator via llvm-commits]

meadori added a comment.

I want to be able to override *any* symbol's value (which is support in GNUnLD, for example).  Currently LLD issues multiple definition errors if I say something like:

  foo = 1

and `foo` is defined in an object file or something.

The `_gp` thing was just a issue I ran into while implementing the general ability to redefine a symbol's value from a linker script because `_gp` is defined by the linker relative to `.got` and thus causes problems when completely overriding it from a linker script.
