[PATCH] D123599: [DebugInfo][InstrRef] Describe value sizes when spilt to stack

Thu Apr 28 16:50:43 PDT 2022

zequanwu added a comment.

The compressed linker repro is 4.3GB, so it's hard to upload. 
here is better backtrace. Hope that helps:

  Assertion failed: !Expr->isComplex(), file ../../llvm/lib/CodeGen/LiveDebugValues/InstrRefBasedImpl.cpp, line 907
  PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
