* cdefs.h: Introduce __nonstring attributeAlex Richardson7 days1-0/+8
| | | | | | | | | | This attribute can be used to annotate char arrays that are not supposed to be terminated with a NUL char and is needed to silence clang's new -Wunterminated-string-initialization warning. The name matches linuxkpi. Reviewed by: emaste, jhb MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D52565
* cross-build: Define __GNUC_PREREQ__ in cdefs.hMark Johnston2025-10-081-0/+10
| | | | | | | | | This is required when including stdckdint.h and doesn't seem to be provided by older clang. Reviewed by: emaste Fixes: 7233893e9496 ("lib{c,openbsd}: use ckd_mul() for overflow checking in re(c)allocarray") Differential Revision: https://reviews.freebsd.org/D52933

* tools/build: Provide extra headers on non-FreeBSDJessica Clarke2025-06-161-0/+3
| | | | | | These will be needed by future changes to continue to allow building makefs as a bootstrap tool on Linux and macOS. This also requires defining __sbintime_t in our cross-build sys/_types.
* cross-build: fix missing <sys/md4.h> the proper wayKyle Evans2024-10-181-91/+0
| | | | | | | | | | Add it to tools/build/Makefile with a short note of where it's needed, rather than hamfistedly copying it into the tools/build hierarchy.

* Fix the cross-build after recent commitsKyle Evans2024-09-301-0/+91
| | | | | | | | | | | - Provide a sys/md4.h in the cross-build environment to fix bootstrap of libmd. - flua now exposes WTRAPPED which isn't incredibly common- make it conditional, we probably won't be using it in any bootstrap context any time soon.

* cross: Move Solaris API64 defines to commonVal Packett2024-05-241-0/+3
| | | | | | | | | off64_t is needed for both Linux (musl) and MacOS, so move them to the common area. Somehow glibc provides the definition, but defining it doesn't hurt and hels in the musl case. Reviewed by: allanjude, jrtc27 Pull Request: https://github.com/freebsd/freebsd-src/pull/1066
* tools/build: Provide sys/linker_set.h when cross-buildingJessica Clarke2023-12-131-0/+13
| | | | | | | | | | This is needed for kldxref, which will shortly become a bootstrap tool. Linux can use the same one as FreeBSD (provided the cross-building sys/cdefs.h is augmented appropriately), whilst macOS needs its own Mach-O-specific implementation.

* Revert "tools/build: Unbreak bmake bootstrap on Linux"Jessica Clarke2023-01-291-8/+0
| | | | | | | Now that make.py no longer has the described hack on Linux we can drop this ugly workaround. This reverts commit fba998a3d897e6297baca74068e4ec1db7adaeec.
* tools/build: Unbreak bmake bootstrap on LinuxJessica Clarke2022-08-221-0/+8
| | | | | | | | | | | | Currently make.py has a hack to add the cross-build headers to the include search path when bootstrapping bmake on Linux (but not macOS). This is a bit of an abuse of these headers, and e9ba1fd5eda2 was not prepared for this, since sys/bitcount.h won't exist in that instance (it gets copied into WORLDTMP during the legacy build). Work around this until we can wean the bmake bootstrap off using these headers by not including sys/bitcount.h when it doesn't exist.

* tools/build: Provide FreeBSD's bitstring API when cross-buildingJessica Clarke2022-08-181-0/+4
