[llvm-dev] LLVM's Inliner broke the code

[Zhang via llvm-dev]

Hi,
The LLVM tools didn't crash, but the inlined code crashed at runtime. I later narrowed down that issue to one function, after I added no inline to that function in my transform pass, everything works normal again. I guess that's a issue with the inliner

                   Hi,
     
     you might want to output --verbose to isolate which command has the     crash and then attach debugger like lldb/gdb to the command to debug     it. Sounds like it might be crashing in opt.
     ie. gdb -tui --args <command>

                   Hi:
       I was using various Inliners on a custom built IR Function         however the code simply results in a NULL Pointer Access crash. 
       How do I debug this issue? The IR code runs perfectly fine         without the Inliner. The Inlined functions contains a lot of         GEP/Load and stores
