* alloc: Don't require size % align == 0Tavian Barnes2024-11-022-9/+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 Barnes2024-10-102-0/+10
| | | | | | 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 Barnes2024-09-144-66/+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/flags: Use auto-detection for all warning flagsTavian Barnes2024-09-059-12/+73

|
* build: Move feature test macros to prelude.hTavian Barnes2024-08-281-13/+1
| | | | | | 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.

* build/flags-if: Fix sed expression on BSDTavian Barnes2024-08-281-1/+1
| | | | | | | | `p` needs a terminating semicolon; otherwise we get sed: 1: "\|^///|{s|^/// ||; s|[^ ...": extra characters at the end of p command Fixes: 3552b79 ("build/flags: Infrastructure to detect compiler flag support")
* build: Allow ./configure --version=X.Y.ZTavian Barnes2024-08-281-0/+1

* xspawn: Use _Fork() if availableTavian Barnes2024-07-274-0/+18
| | | | | | | This completes the workaround for bfs_spawn() hanging on FreeBSD with ASan enabled. Link: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280318

* build: Generate config.mk after config.hTavian Barnes2024-06-212-5/+8

| | | | This avoids extra error reporting from set -e.
* Revert "build: Add -Wmissing-variable-declarations"Tavian Barnes2024-06-081-1/+0
| | | | | | Turns out that flag was only added in GCC 14. This reverts commit 7cddd64b3131812b82feffe2deb311bf6ab9a262.

* build: Allow flags.mk to override command line variablesTavian Barnes2024-05-213-29/+29
| | | | | | | | Previously, during something like ./configure LDFLAGS=..., any additions to LDFLAGS from the generated makefiles were ignored. I had thought that sub-make invocations would allow those variables to be overridden, but that is not the behaviour of make. So instead, set _LDFLAGS etc. in the generated files so that they don't conflict.
