labath added a comment.
So, it seems we were all correct. The mach-o core file implementation does
permit writing registers, while the elf one doesn't. I guess we never got that
feature request for elf.
I don't think that's a blocker for writing this test though. If we decide to
support writing registers in for elf too, we can always change/remove the test.
Another possibility is to use the gdb-client test infrastructure to simulate a
server which refuses to write to a register, but those tests are slightly
tricky to write, so I don't think that's worth it here (unless you're
interested in getting to know that infra, that is).

Comment at:
lldb/test/API/functionalities/postmortem/elf-core/TestLinuxCore.py:151-152
+ reg_value: lldb.SBValue = frame.FindRegister('eax')
+ if not reg_value.IsValid():
+ return
+
----------------
I don't think there's a valid reason for why should this ever fail.
