    ## The issue
An address that symbolizes without issues on DWARF with GNU's `addr2line` does not yield any result on the converted GSYM file. Happy to help with anything, let me know!

## Repro

#### Fetch the DWARF debug info

Which belongs to a Fedora kernel

```
$ wget https://debuginfod.fedoraproject.org/buildid/b8d70cf519fac5a5cccdda1a61c38995bd9b3059/debuginfo
```

#### `addr2line` on the DWARF file works without issues

```
$ addr2line -fe debuginfo 0xffffffff8220012f
entry_SYSCALL_64_after_hwframe
/usr/src/debug/kernel-6.9.11/linux-6.9.11-200.fc40.x86_64/arch/x86/entry/entry_64.S:130
```

#### After converting it

```
$ llvm-gsymutil --convert=debuginfo --out-file=debuginfo.gsym
```
#### `llvm-gsymutil` fails to find the symbol for that same address
```
$ llvm-gsymutil --address=0xffffffff8220012f debuginfo.gsym
Looking up addresses in "/tmp/nix-shell.K7SvqT/.tmpcNXLtG":
0xffffffff8220012f: error: address 0xffffffff8220012f is not in GSYM
```

### Environmental information

```
$ llvm-gsymutil --version
llvm-gsymutil
LLVM (http://llvm.org/):
  LLVM version 18.1.6
  Optimized build.
```

But this also fails on a recent commit:

```
$ git show
commit 9f8c3d3796ebf7ddd4a85134ff109cf03a0b9b5e (grafted, HEAD -> main, origin/main, origin/HEAD)
Author: David Spickett <david.spickett@linaro.org>
Date:   Wed Nov 6 10:42:11 2024 +0000

 [lldb][test] Correct typo in breakpoint test file name
    
    Added by https://github.com/llvm/llvm-project/pull/114896.
```
```
/home/javierhonduco/src/llvm-project/build/bin/llvm-gsymutil
LLVM (http://llvm.org/):
  LLVM version 20.0.0git
  Optimized build.
```

The conversion output: https://gist.github.com/javierhonduco/7d32feaff1b0d04365c6deb1c3a53b8c


Thanks!
