The bitstream reader handles errors poorly. This has two effects: * Bugs in file handling (especially modules) manifest as an "unexpected end of file" crash * Users of clang as a library end up aborting because the code unconditionally calls `report_fatal_error` The bitstream reader should be more resilient and return Expected / Error as soon as an error is encountered, not way late like it does now. This patch starts doing so and adopting the error handling where I think it makes sense. There's plenty more to do: this patch propagates errors to be minimally useful, and follow-ups will propagate them further and improve diagnostics. https://bugs.llvm.org/show_bug.cgi?id=42311 <rdar://problem/33159405> Differential Revision: https://reviews.llvm.org/D63518 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@364464 91177308-0d34-0410-b5e6-96231b3b80d8 |
