* vendor/bc: upgrade to version 7.0.0Stefan Eßer2024-09-031-0/+79
| | | | | | | | | | | | | | | | | | | | | | This is a production release to fix three bugs, none of which affects well formed scripts on FreeBSD: The first bug is that bc/dc will exit on macOS when the terminal is resized. The second bug is that an array, which should only be a function parameter, was accepted as part of larger expressions. The third bug is that the value stack for dc was cleared on any error. However, this is not how other dc behave. To bring dc more in line with other implementations, this behavior was changed. This change is why this version is a new major version.

* pkgbase: Move headers and libs out of runtime and utilitiesDoug Rabson2023-11-122-1/+3
| | | | | | | | | | | | | | | | | | | | | | Headers from src/include were in the runtime-dev package but subdirectories of src/include ended up in utilities-dev by default. Neither package is a good choice - the headers in src/include are not useful without the libraries contained in clibs-dev. This moves the standard C headers to clibs-dev (C++ headers are already in this package). While working on this, I found that various clang libraries and headers were also bundled into utilities-dev by default so these are also moved to clang-dev. I also added a FreeBSD-build-essential meta package to make it simple to install all the toolchain parts.

* arm64 lib32: prepare arm64 headers to redirect to armMike Karels2023-07-252-4/+69
| | | | | | | | | | | | | | | | | | | | | | | In order to compile lib32 libraries and other 32-bit code on arm64, <machine/foo.h> needs to be redirected to an arm header rather than arm64 when building with -m32. Ifdef the arm64 headers that are installed in /usr/include/machine and used by user-level software (including references from /usr/include/*.h) so that if __arm__ is defined when including the arm64 version, <arm/foo.h> is included rather than using the rest of the file's contents. Some arm headers had no arm64 equivalent; headers were added just to do the redirection. These files use #error if __arm__ is not defined to guard against confusion. Also add an include/arm Makefile, and modify Makefiles as needed to install everything, including the arm files in /usr/include/arm. fenv.h comes from lib/msun/arm/fenv.h.

* elf-hints.h: Allow rtld_paths.h to be included before itJessica Clarke2023-07-091-0/+2
| | | | | | | | | | | | | | | | | Currently rtld_paths.h will #undef _PATH_ELF_HINTS in order to override this to the right value if included afterwards, but the other way round does not work as elf-hints.h tries to define an already-defined macro to a potentially different value. Thus, guard the definition here so that rtld_paths.h's definition continues to take precedence. Note that, although all in-tree uses of _PATH_ELF_HINTS have included rtld_paths.h already, pax-utils wants _PATH_ELF_HINTS from elf-hints.h and so we cannot just drop the define. In-tree uses must just continue to make sure that they include rtld_paths.h to get the right value for libcompat builds as is already required.

| | | | | | | | | | | | | | | | | | | | | | | | Some points for the future: - libc is not the right place for sorting algorithms. Probably libutil is better suited for this purpose or a dedicated libsort. Should move all sorting algorithms away from libc eventually. - CheriBSD uses capabilities for memory access, and could benefit from a standard memswap() function. - Do something about qsort() in FreeBSD's libc like: - Mark it deprecated on FreeBSD, as a first step, due to missing limits on CPU time. - Audit the use of qsort() in the FreeBSD base system and consider swapping to other existing sorting algorithms.

* libc: Implement bsort(3) a bitonic type of sorting algorithm.Hans Petter Selasky2023-04-191-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | The bsort(3) algorithm works by swapping objects, similarly to qsort(3), and does not require any significant amount of additional memory. The bsort(3) algorithm doesn't suffer from the processing time issues known the plague the qsort(3) family of algorithms, and is bounded by a complexity of O(log2(N) * log2(N) * N), where N is the number of elements in the sorting array. The additional complexity compared to mergesort(3) is a fair tradeoff in situations where no memory may be allocated. The bsort(3) APIs are identical to those of qsort(3), allowing for easy drop-in and testing. The design of the bsort(3) algorithm allows for future parallell CPU execution when sorting arrays. The current version of the bsort(3) algorithm is single threaded. This is possible because fixed areas of the sorting data is compared at a time, and can easily be divided among different CPU's to sort large arrays faster.

There may be one or two upstreams that haven't integrated the patches I tried to send up. There are some minor differences: o The extra glibc macros are not defined. These are all controlled with either __ at the start, or only defined when glibc is being built. We also don't define macros that are used internally in glibc that would pollute the namespace. o For complete compatibility, this change must also be paired with providing a glibc-compatible byteswap.h.

For `copies`, we were supplying the include/ ${TAG_ARGS}, which puts packages into `FreeBSD-runtime`, without any consideration to the fact that we're installing headers. Let's copy the approach that the `symlinks` target uses for now, and add ",dev" to the TAG_ARGS so that headers at least end up in FreeBSD-runtime-dev, which is more appropriate. Some of these includes are actually technically supposed to be in *other* packages and their INCSGROUP's PACKAGE setting is actually correct, but this is less trivial to solve.
