tfiala created this revision.
tfiala added reviewers: labath, zturner, spyffe.
tfiala added a subscriber: lldb-commits.
This change does the following:
* Adds a cached LLDB_ALLOW_STATIC_BINDINGS variable, defaults to off/false
* If specified, flips on the --allow-static-binding flag to prepare_bindings.py
* Removes the REQUIRED marker in cmake-based swig discovery, but adds a fatal
error for cmake if swig isn't found when LLDB_ALLOW_STATIC_BINDINGS is also not
set. i.e. unless -DLLDB_ALLOW_STATIC_BINDINGS=1 is specified on the command
line, not finding swig will fail the cmake step as before.
As noted in a prior thread, I will be happy to rip this out once we no longer
require swig via other means. This can be considered temporary until that time.
