    The `LLVM :: tools/dsymutil/ARM/stmt-seq-macho.test` test `FAIL`s on `sparcv9-sun-solaris2.11`:
```

```
Looking at how the `.dSYM` file is generated, I find lots of warnings:
```
+ /var/llvm/local-sparcv9-release-stage2-A-flang-clang20/tools/clang/stage2-bins/bin/dsymutil --flat --verify-dwarf=none -oso-prepend-path /var/llvm/local-sparcv9-release-stage2-A-flang-clang20/tools/clang/stage2-bins/test/tools/dsymutil/ARM/Output/stmt-seq-macho.test.tmp /var/llvm/local-sparcv9-release-stage2-A-flang-clang20/tools/clang/stage2-bins/test/tools/dsymutil/ARM/Output/stmt-seq-macho.test.tmp/stmt_seq_macho.exe -o /var/llvm/local-sparcv9-release-stage2-A-flang-clang20/tools/clang/stage2-bins/test/tools/dsymutil/ARM/Output/stmt-seq-macho.test.tmp/stmt_seq_macho.dSYM
warning: Invalid location attribute ignored.
note: while processing /var/llvm/local-sparcv9-release-stage2-A-flang-clang20/tools/clang/stage2-bins/test/tools/dsymutil/ARM/Output/stmt-seq-macho.test.tmp/stmt_seq_macho.o
```
and many more.

So it seems something is wrong with the `.exe` file generated by `yaml2obj`.  And indeed if I take the `.dSYM` file generated  on `amd64-pc-solaris2.11` instead, the `.dSYM` creating step works without warnings , as does the `llvm-dwarfdump` invocation.

This seems like an endianess issue to me: `cmp -l` on the `.exe` files shows
```
    1 317 376
    2 372 355
    3 355 372

```
and much more.
