On windows if you passed /lldltocache:D:\tmp to lld and you didn't have D: mounted it fail to create the cache dir D:\tmp, but the error message is pretty hard to understand: ``` c:\code\llvm\llvm-project\out\debug>bin\lld-link.exe /lldltocache:D:\tmp hello.obj LLVM ERROR: no such file or directory PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. Exception Code: 0xC000001D ``` Which lead one of our users to report this as a crash. I have just added a bit better message so it now says: ``` c:\code\llvm\llvm-project\out\debug>bin\lld-link.exe /lldltocache:D:\tmp hello.obj LLVM ERROR: Can't create cache directory: D:\tmp PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. ``` I am not sure this is a fatal error because it's not something that really should be reported as a bug to LLVM. But at least this gives a bit more visibility on what to change.
