I don't know this is a real bug or just my input, but I'm stuck and the message says file a bug so here I am.
With wasm-ld version
```
E:\GitHub\w4>E:/GitHub/emsdk/upstream/bin\wasm-ld.exe --version
LLD 14.0.0
```
The one that comes with emscripten tot,
```
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.0.2-git (e4163cc2a5ea43a103dc8eda3c1b8620ec0d991e)
```
And with the command line
```
E:/GitHub/emsdk/upstream/bin\wasm-ld.exe -o hello-wasm.wasm hello.bc -mllvm -combiner-global-alias-analysis=false -mllvm -disable-lsr --import-undefined --strip-debug --export-if-defined=__start_em_asm --export-if-defined=__stop_em_asm --export-if-defined=fflush --export=emscripten_stack_get_end --export=emscripten_stack_get_free --export=emscripten_stack_init --export=stackSave --export=stackRestore --export=stackAlloc --export=__wasm_call_ctors --export=__errno_location --export-table -z stack-size=5242880 --initial-memory=16777216 --max-memory=16777216 --global-base=1024 --export=update --no-entry
```
And the attached bitcode (extract from attached zip)
[hello.zip](https://github.com/llvm/llvm-project/files/7740919/hello.zip)
)
I get the message
```
E:\GitHub\w4>E:/GitHub/emsdk/upstream/bin\wasm-ld.exe -o hello-wasm.wasm hello.bc -mllvm -combiner-global-alias-analysis=false -mllvm -disable-lsr --import-undefined --strip-debug --export-if-defined=__start_em_asm --export-if-defined=__stop_em_asm --export-if-defined=fflush --export=emscripten_stack_get_end --export=emscripten_stack_get_free --export=emscripten_stack_init --export=stackSave --export=stackRestore --export=stackAlloc --export=__wasm_call_ctors --export=__errno_location --export-table -z stack-size=5242880 --initial-memory=16777216 --max-memory=16777216 --global-base=1024 --export=update --no-entry

If I remove the `--export=update` then it doesnt error ( it does complain about missing symbols as I have them in another `.bc` which isn't necessary to repro this error message).
