```
$ llvm-objdump --version
Fuchsia LLVM version 21.0.0git
...
```
`--help` indicates that `--mcpu=help` should provide details for the `--mcpu` option:
```
$ llvm-objdump --help
OVERVIEW: llvm object file dumper
USAGE: llvm-objdump [options] <input object files>
OPTIONS:
...
--mcpu=cpu-name Target a specific cpu type (--mcpu=help for details)
...
```
If I do only that, it just outputs the normal help again:
```
$ llvm-objdump --mcpu=help
OVERVIEW: llvm object file dumper
...
```
But if I provide it an input file, then it provides the CPU help:
```
$ llvm-objdump --mcpu=help -d a.out >/dev/null
Available CPUs for this target:
arm1020e - Select the arm1020e processor.
...
```
It seems like `--mcpu=help` should bypass the rest of the argument checking.
