Subject: [PATCH] lib: remove pure attribute from functions that modify memory
|
||||
|
||||
Almost all functions currently marked with pure attribute acquire a
|
||||
route_node lock. By marking them pure we allow compiler to optimize the
|
||||
code and not call them when it already knows the return value. This is
|
||||
completely incorrect.
|
||||
|
||||
Only two of eleven functions can be marked as pure. And they still won't
|
||||
be optimized because they are never called from the same function twice.
|
||||
Let's remove the ext_pure macro completely to reduce the chance of
|
||||
repeating this mistake in the future.
|
||||
|
||||
Fixes #8866, #8809, #8595, #6992.
