* bftw: Only do another level of deepening if there are unexplored directoriesTavian Barnes2020-06-121-3/+4
| | | | This makes -S ids about 20% faster on a checkout of the Linux kernel.
* bftw: Make iterative deepening actually do depth-first searchTavian Barnes2020-06-121-15/+21
| | | | | | | | | bftw_stream() was always pushing to the end of the queue, resulting in breadth-first behaviour even when BFTW_DFS was set. This made iterative deepening a "worst of both worlds" with the same memory use as BFS, but much slower due to re-traversals. Fix it by re-using bftw_batch_{start,finish} from bftw_batch().

* Makefile: Don't use target-specific variables for configuration targetsTavian Barnes2020-03-241-17/+28
| | | | | | | | | | | | | | | | | | | In things like release: CFLAGS := ... release: bfs CFLAGS is only set for the dependencies of release, so $ make release check doesn't set CFLAGS for tests/mksock. For the same reason, $ make asan ubsan was broken, because only the asan flags would be set for bfs. Fix it by checking MAKECMDGOALS for those targets manually instead.

* opt: Avoid dangling pointers in de_morgan()Tavian Barnes2020-03-231-5/+7
| | | | | | | | If optimize_{and,or}_expr() relocates expr, we need to update the parent expr or else we might return garbage. It seems impossible to actually trigger this bug right now, since the {and,or} optimizations are symmetric, but it could be hit if the simplifications in de_morgan() expose more information than was known previously.
