Since we need an heuristic, we may as well use the same one asgas:* call weak_sym : produces a relocation, even if in the same section.* A - weak_sym and weak_sym -A: don't produce a relocation if we can compute it.This fixes pr23272 and changes the fix of pr22815 to match what gas does.llvm-svn: 235227 List of files: /llvm-project-15.0.7/llvm/test/MC/ELF/weak-diff.s Fri, 17 Apr 2015 21:15:17 +0000 Rafael Espindola <rafael.espindola@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/ELF/weak-diff.s#c9e7068c Don't be over eager in evaluating a subtraction with a weak symbol.In a subtraction of the form A - B, if B is weak, there is no way to representthat on ELF since all relocations add the value of a symbol.llvm-svn: 233139 List of files: /llvm-project-15.0.7/llvm/test/MC/ELF/weak-diff.s Tue, 24 Mar 2015 23:48:44 +0000 Rafael Espindola <rafael.espindola@gmail.com>
