Subject: [PATCH 0/4] Optimize red-black tree insert/extract
Date: Tue, 5 Oct 2021 16:16:21 +0200 [thread overview]
Message-ID: <20211005141625.31585-1-sebastian.huber@embedded-brains.de> (raw)
Code coverage analysis of the red-black tree insert/extract operations defined
in <sys/tree.h> showed that the macros contain dead code. This patch set
simplifies some expressions and add specialized rotations.
Sebastian Huber (4):
sys/tree.h: Simplify loop condition
sys/tree.h: Simplify chain of conditions
sys/tree.h: Add parent rotations
sys/tree.h: Red child with black sibling rotations
