URL: https://github.com/llvm/llvm-project/commit/e414ede2cd54b03f3ff7d547132f06d1b836e5bb DIFF: https://github.com/llvm/llvm-project/commit/e414ede2cd54b03f3ff7d547132f06d1b836e5bb.diff LOG: [lldb] [test/Register] Initial tests for regsets in core dumps Add initial tests for reading register sets from core dumps. This includes a C++ program to write registers and dump core, resulting core dumps for Linux, FreeBSD and NetBSD, and the tests to verify them. The tests are split into generic part, verifying user-specified register values, and coredump-specific tests that verify memory addresses that differ for every dump. At this moment, all platforms support GPRs and FPRs up to XMM for amd64 target. The i386 target does not work on NetBSD at all, and is missing FPRs entirely on FreeBSD.
