URL: https://github.com/llvm/llvm-project/commit/b5491dd30792c1ad31bfc8e2f9d1809a79205234 DIFF: https://github.com/llvm/llvm-project/commit/b5491dd30792c1ad31bfc8e2f9d1809a79205234.diff LOG: ObjectFile: add a case for `EM_RISCV` This adds the jump slot mapping for RISCV. This enables lldb to attach to a remote debug server. Although this doesn't enable debugging RISCV targets, it is sufficient to attach, which is a slight improvement. Tested with DebugServer2: ~~~ (lldb) gdb-remote localhost:1234 (lldb) Process 71438 stopped * thread #1, name = 'reduced', stop reason = signal SIGTRAP frame #0: 0x0000003ff7fe1b20 error: Process 71438 is currently being debugged, kill the process before connecting.
