================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:19116
if (OpFlags == X86II::MO_NO_FLAG &&
- X86::isOffsetSuitableForCodeModel(Offset, M)) {
+ X86::isOffsetSuitableForCodeModel(Offset, M, true, true)) {
std::swap(GlobalOffset, Offset);
----------------
Maybe just need to add `Offset >=0 &&` here?
