During randconfig testing with clang-9, I came across an object file that makes objtool segfault, see attachment. Let me know if you need more information to debug this.
I also get a ton of objtool warnings building random configurations, but Nick mentioned that there is still a bug related to asm-goto in the build I'm using that may be the root cause. Once I have a fixed clang-9 build, I can have a look at those as well. Arnd
