Bug ID: 39558
Summary: obj2yaml crashes on object files created by llvm-mc
Product: libraries
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: WebAssembly
Assignee: unassignedb...@nondot.org

Test case .ll file
This bug was accidentally discovered while filing
https://bugs.llvm.org/show_bug.cgi?id=39557. The test case is the same with
PR39557 except now function 'foo' does not take an argument. I don't know why,
but now obj2yaml crashes on reading the object file created from .s file using
llvm-mc. llvm-objdump crashes too.
Commands that reproduce the bug:
```
llc -filetype=asm -asm-verbose=false test.ll -o test.s
llvm-mc -triple=wasm32-unknown-unknown -filetype=obj test.s -o test_from_s.o
obj2yaml test_from_s.o > test_from_s.yaml <-- crashes!
llvm-objdump -disassemble test_from_s.o <-- crashes too!
```
