Subject: [PATCH 0/2] gcc-plugins: structleak: Generalize to all variable types
Instead of a new plugin for stack initialization[1], this improves
structleak to handle initialization of all variable types. Since the
instrumentation happens at a different point, the "switch" statement
changes from the earlier posting[2] are no longer needed. As before,
this also introduces a stack initialization regression testing module to
validate various kinds of stack variable usage vs compiler instrumentation
for initialization. See the individual patches for more details.
Thanks!
