* MFC r312332,r312446,r312451:ngie2017-02-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r312332: Use SRCTOP where possible and use :H to manipulate .CURDIR to get rid of unnecessarily long relative path .PATH values with make r312446 (by emaste): libc: remove reference to nonexistent lib/locale directory As far as I can tell this was introduced in r72406 and updated in several subsequent revisions, but the lib/locale directory it referenced never existed. r312451: Replace dot-dot relative pathing with SRCTOP-relative paths where possible This reduces build output, need for recalculating paths, and makes it clearer which paths are relative to what areas in the source tree. The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS. LIBC_SRCTOP was left alone so Juniper (and other users) can continue to manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as include Makefiles with custom options.

* Update jemalloc to 4.1.0.jasone2016-02-292-2/+7
| | | | | | | | | | Add missing Symbol.map entry for __aligned_alloc. Add weak-->strong symbol binding for {malloc_stats_print,mallctl,mallctlnametomib,mallctlbymib} --> {__malloc_stats_print,__mallctl,__mallctlnametomib,__mallctlbymib}. These bindings complete the set necessary to allow applications to replace all malloc-related symbols.

* META MODE: Don't create .meta files when symlinking sources into the obj ↵bdrewery2015-11-251-4/+4
| | | | | | | | | | | directory. Tracking these leads to situations where meta mode will consider the file to be out of date if /bin/sh or /bin/ln are newer than the source file. There's no reason for meta mode to do this as make is already handling the rebuild dependency fine. Sponsored by: EMC / Isilon Storage Division

* Fix known issues which blow up the process after dlopen("libthr.so")kib2015-01-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (or loading a dso linked to libthr.so into process which was not linked against threading library). - Remove libthr interposers of the libc functions, including __error(). Instead, functions calls are indirected through the interposing table, similar to how pthread stubs in libc are already done. Libc by default points either to syscall trampolines or to existing libc implementations. On libthr load, libthr rewrites the pointers to the cancellable implementations already in libthr. The interposition table is separate from pthreads stubs indirection table to not pull pthreads stubs into static binaries. - Postpone the malloc(3) internal mutexes initialization until libthr is loaded. This avoids recursion between calloc(3) and static pthread_mutex_t initialization. - Reinstall signal handlers with wrapper on libthr load. The _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2) when libthr is statically referenced from the main binary. In the process, fix openat(2), swapcontext(2) and setcontext(2) interposing. The libc symbols were exported at different versions than libthr interposers. Export both libc and libthr versions from libc now, with default set to the higher version from libthr. Remove unused and disconnected swapcontext(3) userspace implementation from libc/gen.

* Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}marcel2014-03-041-5/+5
| | | | | | | | | | | 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.
