Changed all paths to be relative to src/lib instead of src/lib/libc so that all these makefiles can be used to build libc_r too. Added .if ${LIB} == "c" tests to restrict man page builds to libc to avoid needlessly building them with libc_r too. Split libc Makefile into Makefile and Makefile.inc to allow the libc_r Makefile to include Makefile.inc too.

Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.

Export __cxa_thread_atexit_impl as an alias for __cxa_thread_atexit. libstdc++ before gcc r244057 expected that libc provided __cxa_thread_atexit_impl, and libstdc++ implemented __cxa_thread_atexit, by forwarding the calls to _impl. Mentioned gcc revision checks for __cxa_thread_atexit in libc and does not provide the symbol from libstdc++ if found. This change helps older gcc, in particular, all released versions which implement thread_local, by consolidating the implementation into libc. For that versions, if configured with the current libc, the __cxa_thread_atexit is exported from libstdc++ as a trivial wrapper around libc::__cxa_thread_atexit_impl. The __cxa_thread_atexit implementation is put into separate source file to allow for static linking with older libstdc++.a. gcc bugzilla: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78968 Reported by: Hannes Hauswedell <h2+fbsdports@fsfe.org> PR: 215709 Sponsored by: The FreeBSD Foundation MFC after: 2 weeks

Replace implementation of hsearch() by one that scales. Traditionally the hcreate() function creates a hash table that uses chaining, using a fixed user-provided size. The problem with this approach is that this often either wastes memory (table too big) or yields bad performance (table too small). For applications it may not always be easy to estimate the right hash table size. A fixed number only increases performance compared to a linked list by a constant factor. This problem can be solved easily by dynamically resizing the hash table. If the size of the hash table is at least doubled, this has no negative on the running time complexity. If a dynamically sized hash table is used, we can also switch to using open addressing instead of chaining, which has the advantage of just using a single allocation for the entire table, instead of allocating many small objects. Finally, a problem with the existing implementation is that its deterministic algorithm for hashing makes it possible to come up with fixed patterns to trigger an excessive number of collisions. We can easily solve this by using FNV-1a as a hashing algorithm in combination with a randomly generated offset basis. Measurements have shown that this implementation is about 20-25% faster than the existing implementation (even if the existing implementation is given an excessive number of buckets). Though it allocates more memory through malloc() than the old implementation (between 4-8 pointers per used entry instead of 3), process memory use is similar to the old implementation as if the estimated size was underestimated by a factor 10. This is due to the fact that malloc() needs to perform less bookkeeping.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Implement quick_exit() / at_quick_exit() from C++11 / C1x. Also add a __noreturn macro and modify the other exiting functions to use it. The __noreturn macro, unlike __dead2, must be used BEFORE the function. This is in line with the C and C++ specifications that place _Noreturn (c1x) and [[noreturn]] (C++11) in front of the functions. As with __dead2, this macro falls back to using the GCC attribute. Unfortunately, clang currently sets the same value for the C version macro in C99 and C1x modes, so these functions are hidden by default. At some point before 10.0, I need to go through the headers and clean up the C1x / C++11 visibility. Reviewed by: brooks (mentor)
