[lldb-dev] Global lldbinit file?

[Greg Clayton]

Then you should be able to have a ".lldbinit-hexagon-lldb" file that will get sourced. The main questions is if there is a good place to put this file when there are no bundles on linux or windows. On LLDB, the LLDB.framework contains everything we need (headers, resources, support binaries (debugserver, lldb-gdbserver lldb-platform, darwin-debug, and more) and the lldb python modules.

Maybe we can start paving the way for bundles on windows and linux with LLDB?

I can do this with custom drivers (1 for lldb, 1 for lldb-mi), but I'd hoped to stay as close to the upstream code as possible.

But I don't see that strong a use case for that for lldb.  Plus, the particular instance seems another counter-argument, since as I understand it the Hexagon init is going to change the behavior of lldb significantly.  I would rather if that happen I know this is not vanilla lldb, because it is called "lldb-hex" or something...

Currently I do this by having lldb be a wrapper script that calls lldb with –o, but I’d like to eliminate the wrapper script, since wrapper batch files cause problems with ctrl-c handling on Windows. I use this to load a python file with utilities in it, like one to get the TLB info from the target. It sends a qXfer command to the remote GDB server to download an XML file, parses it, and prints the info from it. These utilities need to load for all users.
