![]() Currently, if an assembly file includes a static reference to an undefined symbol, and another package also has an undefined reference to that symbol, the linker can report an error like: x: relocation target zero not defined for ABI0 (but is defined for ABI0) Since the symbol is referenced in another package, the code in ErrorUnresolved that looks for alternative ABI symbols finds that symbol in the symbol table, but doesn't check that it's actually defined, which is where the "but is defined for ABI0" comes from. The "not defined for ABI0" is because ErrorUnresolved failed to turn the static symbol's version back into an ABI, and it happened to print the zero value for an ABI. This CL fixes both of these problems. It explicitly maps the relocation version back to an ABI and detects if it can't be mapped back (e.g., because it's a static reference). Then, if it finds a symbol with a different ABI in the symbol table, it checks to make sure it's a definition, and not simply an unresolved reference. Fixes #29852.
