Subject: [lldb/Interpreter] Add setting to set session transcript save directory
X-Git-Tag: llvmorg-14-init~2750
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fe1874dd2dd99c9811db515a2957e2a42f9f6868;p=platform%2Fupstream%2Fllvm.git

[lldb/Interpreter] Add setting to set session transcript save directory

This patch introduces a new interpreter setting
`interpreter.save-session-directory` so the user can specify a directory
where the session transcripts will be saved.

If not set, the session transcript are saved on a temporary file.
