[ELF] Better error reporting for undefined symbols This patch make lld show following details for undefined symbol errors: - file (line) - file (function name) - file (section name + offset) Differential revision: https://reviews.llvm.org/D25826 llvm-svn: 285186

[ELF] Prevent crash when reporting errors if debug line cannot be parsed LLD uses the debug info and debug line sections to determine the location of e.g. references to undefined symbols, when producing error messages. In the event that debug info was present, but debug line parsing failed for some reason, then a nullptr would end up being dereferenced by the location-lookup code.

[lld] Make tests calling llvm-ar more robust Some lit tests that call llvm-ar use the 'r' flag. If the target archive already exists and is in a corrupt state, this can cause the test to fail. We have added 'rm -f' calls before the llvm-ar calls to increase the robustness of the tests. Differential revision: https://reviews.llvm.org/D49184 llvm-svn: 338705

Add a doc for missing key function and an error message referencing the doc. Summary: This is a common error, and because many people don't know what the key function is, it is sometimes very confusing. The doc was originally written by Brooks Moses and slightly edited by me.

[ELF] Rework debug line parsing to use llvm::Error and callbacks (LLD-side) Reviewed by: ruiu, grimar, espindola Differential Revision: https://reviews.llvm.org/D44562 Summary: r331971 changes the debug line parser interface to report LLVM errors in an interface that different executables can use, rather than always being printed directly as warnings to stderr. This change allows LLD to make use of the new interface and call its own warning methods to report problems. llvm-svn: 331972
