[lldb-dev] Target and platform clarification request

[Matthew Gardiner]

Hi all,

I have modified my local copy of lldb in order that it can gdb-remote to 
an in-house gdb-rsp server. However after I connect to my target, the 
target list command informs me that my target's platform is "host".

e.g.

(lldb) target list
Current targets:
* target #0: 
/home/mg11/src/main/devtools/main/heracles/csrgdbserver/test/examples/simple/kalgsd5te_hello.elf 
( arch=kalimba-csr-unknown, platform=host, pid=1, state=stopped )

Is this correct for a embedded target connected over gdb-rsp?

When I invoke platform list I see:

(lldb) platform list
Available platforms:
host: Local Linux user platform plug-in.
remote-freebsd: Remote FreeBSD user platform plug-in.
remote-linux: Remote Linux user platform plug-in.
remote-windows: Remote Windows user platform plug-in.
remote-gdb-server: A platform that uses the GDB remote protocol as the 
communication transport.

So I wondered why my target doesn't report remote-gdb-server as it's 
target. Should it?

Could someone clarify what this concept of platform means? I understand 
the concept of the host as being the Machine/OS where the debugger user 
is worked at, and the target as being the "thing being debugged", which 
could be co-located on the host (in either a 32-bit or 64-bit form) or 
remotely located, in particular for an embedded device, but where does 
the idea of the platform fit in?

all help appreciated,
Matthew Gardiner
