* trie: Fix varena_free() with wrong sizeTavian Barnes2024-11-021-8/+8
| | | | | | | In trie_remove(), clearing the bit before trie_node_collapse() causes us to free the old node with size 1 instead of 2, putting it on the wrong freelist. This is technically safe with the current arena implementation, but not intentional.
* trie: Switch the tag bits aroundTavian Barnes2024-10-081-31/+28
| | | | | | First of all, almost all checks were !trie_is_leaf(), so it makes sense to use trie_is_node() instead. Secondly, using the tag bit for internal nodes allows us to remove some NULL checks.
* trie: Add some extra bounds checkingTavian Barnes2024-10-081-13/+24
|
* build: Move feature test macros to prelude.hTavian Barnes2024-08-281-1/+0
| | | | | | This replaces the explicit CPPFLAGS list in flags.mk with just `-include src/prelude.h`, shortening our compiler command lines and allowing them to be easily documented.
* prelude: Split bfs-specific utilities into new bfs.h headerTavian Barnes2024-08-281-0/+3
|
* diag: Get rid of bfs_static_assert()Tavian Barnes2024-08-281-1/+1
| | | | | In most cases, it's not too annoying to specify a message. For tests/bit.c, we can manually polyfill the 1-argument version.
