From ec4ceb797a963b2d24b02d40fad6cc456fac3e5b Mon Sep 17 00:00:00 2001 From: Jim Grosbach Date: Wed, 18 Jan 2012 21:54:12 +0000 Subject: [PATCH] MCAssembler tweak for determining when a symbol difference is resolved. If the two fragments are in the same Atom, then the difference expression is resolvable at compile time. Previously we were checking that they were in the same fragment, but that breaks down in the presence of instruction relaxation which has multiple fragments in the same atom. rdar://10711829 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148423 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/MC/MachObjectWriter.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/MC/MachObjectWriter.cpp b/lib/MC/MachObjectWriter.cpp index ce222b75cf4..a3445219f1e 100644 --- a/lib/MC/MachObjectWriter.cpp +++ b/lib/MC/MachObjectWriter.cpp @@ -591,7 +591,8 @@ IsSymbolRefDifferenceFullyResolvedImpl(const MCAssembler &Asm, if (!Asm.getBackend().hasReliableSymbolDifference()) { if (!SA.isInSection() || &SecA != &SecB || - (!SA.isTemporary() && &FB != Asm.getSymbolData(SA).getFragment())) + (!SA.isTemporary() && + FB.getAtom() != Asm.getSymbolData(SA).getFragment()->getAtom())) return false; return true; }
