Jonas Devlieghere	3746906193	[lldb] Add reproducer verifier ... Add a reproducer verifier that catches: - Missing or invalid home directory - Missing or invalid working directory - Missing or invalid module/symbol paths - Missing files from the VFS The verifier is enabled by default during replay, but can be skipped by passing --reproducer-no-verify.

Jonas Devlieghere	a842950b62	[lldb] Add a SymbolFileProvider to record and replay calls to dsymForUUID ... When replaying a reproducer captured from a core file, we always use dsymForUUID for the kernel binary. When enabled, we also use it to find kexts. Since these files are already contained in the reproducer, there's no reason to call out to an external tool. If the tool returns a different result, e.g. because the dSYM got garbage collected, it will break reproducer replay. The SymbolFileProvider solves the issue by mapping UUIDs to module and symbol paths in the reproducer. Differential revision: https://reviews.llvm.org/D86389	2020-08-24 15:09:08 -07:00
