* alloc: Don't require size % align == 0Tavian Barnes2024-11-021-1/+0
| | | | | | | | | Allowing unaligned sizes will allow us to allocate aligned slabs with additional metadata in the tail without ballooning the allocation size for large alignments.

* xtime: Add a wrapper for timer_create()/setitimer()Tavian Barnes2024-10-101-0/+1
| | | | | | setitimer() is obsolescent in POSIX 2008 and removed from POSIX 2024. However, at least macOS doesn't implement the new timer_create() API, so we still need the setitimer() fallback.
* build: Remove gen/deps.mkTavian Barnes2024-09-141-1/+0
| | | | | | | | | | | | | | | | Since commit 3552b79 ("build/flags: Infrastructure to detect compiler flag support"), this file only listed a bunch of lines like -include obj/src/alloc.d -include obj/src/bar.d ... We can do that just as well from the main Makefile, and in one line too: -include ${OBJS:.o=.d} This lets us pull the list of all objects out of build/prelude.mk and put it closer to where those objects are actually used.

* build: Replace `make config` with a `./configure` scriptTavian Barnes2024-04-291-0/+69
This lets us do more traditional out-of-tree builds like $ ../path/to/bfs/configure $ make The .mk files are moved from ./config to ./build, mostly so that ./configure will auto-complete easily.
