RFC: Absolute or "fixed address" symbols as immediate operands
...local, the value is
loaded from the GOT (or a synthetic GOT entry), which again means
suboptimal code. If the reference is known to be DSO-local, the symbol will
be referenced with a PC relative relocation and therefore cannot be
resolved properly to an absolute value (c.f. https://reviews.llvm.org/D19844).
The latter case in particular would seem to indicate that a
representational change is required for correctness to distinguish
references to absolute symbols from references to regular symbols.
The specific change I have in mind is to allow !range metadata on
GlobalObjects. This would
be similar...
