In many situations, we don't want to exit at the first error even in the process model. For example, it is better to report all undefined symbols rather than reporting the first one that the linker picked up randomly. In order to handle such errors, we don't need to wrap everything with ErrorOr (thanks for David Blaikie for pointing this out!) Instead, we can set a flag to record the fact that we found an error and keep it going until it reaches a reasonable checkpoint. This idea should be applicable to other places. For example, we can ignore broken relocations and check for errors after visiting all relocs. In this patch, I rename error to fatal, and introduce another version of error which doesn't call exit. That function instead sets HasError to true. Once HasError becomes true, it stays true, so that we know that there was an error if it is true. I think introducing a non-noreturn error reporting function is by itself a good idea, and it looks to me that this also provides a gradual path towards lld-as-a-library (or at least embed-lld-to-your-program) without sacrificing code readability with lots of ErrorOr's. http://reviews.llvm.org/D16641 llvm-svn: 259069 |
