Bug ID: 48371
Summary: LLDB needs a better way of expressing unavailable
registers (test_register_commands failure)
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: All Bugs
Assignee: lldb-...@lists.llvm.org
Reporter: mgo...@gentoo.org
CC: ema...@freebsd.org, jdevliegh...@apple.com,

LLDB can currently only hide unavailable registers via manipulating the global
register count, i.e. hide the last registers on the list. This doesn't work
for FreeBSD and NetBSD, and could also be problematic as new CPUs emerge (or
possibly already is).
Unavailable registers not being hidden cause test_register_commands to fail:
FAIL: test_register_commands (TestRegisters.RegisterCommandsTestCase)
Test commands related to registers, in particular vector registers.
