WebAssembly doesn't support PC relative relocation or relocation expressions that can't be reduced to single symbol. The only support for we have for fixups involving two symbols are when both symbols are defined and withing the same section. In this case evaluateFixup will already have evaluated to the expression before calling recordRelocation. llvm-svn: 369317
