2012-06-15include pthreadP.h for SIGCANCELPeter S. Mazinger
based on a patch from Kevin Cernekee <cernekee@gmail.com> Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-06-15signal: remove sigblock, siggetmask and sigsetmaskPeter S. Mazinger
rcmd.c uses sigblock and sigsetmask, make the function static and include them directly until a rewrite is done. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15sigpause.c: provide the X/Open variant, since the BSD version is deprecatedPeter S. Mazinger
Do not export __sigpause. Provide __bsd_sigpause (unprototyped) if anyone may need it. Adapt cancellation to use cancel.h. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15rework cancellation for sigwait, sigtimedwait and sigwaitinfoPeter S. Mazinger
sigtimedwait: - provide __sigtimedwait_nocancel - use __SYSCALL_SIGSET_T_SIZE instead of _NSIG / 8 - do not provide __sigtimedwait - guard a section to avoid failure on archs if SI_TKILL/SI_USER are not defined sigwaitinfo: - simply use sigtimedwait since that handles cancellation already sigwait: - use non-cancellable functions (sigtimedwait, sigsuspend) - get rid of code already done in __sigtimedwait_nocancel Signed-off-by: Peter S.

2012-01-15libc: build abort with unwind-info for backtraceBernhard Reutner-Fischer
If backtrace support is turned on, build raise() and abort() with unwind info (fixup 4c9b7f3c21ff21c199e54bfad2fdf3445fa4573d). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-01-13libc: allow to backtrace out of abort callCarmelo Amoroso
Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function.
