[Lldb-commits] [lldb] [lldb] Assert on invalid default {S, U}Int64 (NFC) (PR #126590)

[Jonas Devlieghere via lldb-commits]

https://github.com/JDevlieghere created https://github.com/llvm/llvm-project/pull/126590

Both the default value and the min/max value are within LLDB's control, so an assert is more appropriate than a runtime check.

Subject: [PATCH] [lldb] Assert on invalid default {S,U}Int64 (NFC)

Both the default value and the min/max value are within LLDB's control,
so an assert is more appropriate than a runtime check.
