* Add __generic(), to be able to use a very simple _Generic().Ed Schouten2012-01-051-0/+18
| | | | | | | | | Already introducing this allows us to be forward compatible with C11 compilers. By implementing <tgmath.h> on top of this interface, it becomes trivial to support both our existing GCC and newer compilers. Notes: svn path=/head/; revision=229574

* Simply disallow <stdnoreturn.h> to be used in combination with C++.Ed Schouten2012-01-031-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | There is no way one could possibly use this header file in combination with C++ code. The problem is that in C11 the `noreturn' macro expands to the `_Noreturn' function specifier, while in C++11 the `noreturn' keyword is an attribute. So in C11 you have to write: noreturn void exit(int status); While in C++11 you have to write: [[noreturn]] void exit(int status); It is impossible to #define noreturn for C++ in such a way that it allows both conventions. By intentionally breaking this header this way, we prevent people from using this header in their C++<11 sources. Notes: svn path=/head/; revision=229437

| | | | | | | | | | | | | | | | | | | | | 'comconsole_pcidev'. The former allows to set the base address of the serial console i/o port. The later takes the string of the format 'bus:device:function:[bar]' as a value and uses the serial port attached as PCI device at the specified location for console. Both variants pass 'hw.uart.console' variable to the uart driver to properly hand-over the kernel console. Change allows to use ISA serial ports other than COM1 for the loader/kernel console without loader recompilation. Also, you can use PCI-attached port as the console, e.g. Intel AMT serial pseudo-port on some motherboards based on Q67 chipset.

* Some small fixes to CPU accounting for threads:John Baldwin2012-01-033-14/+19
| | | | | | | | | | | | | | | | | | | - Only initialize the per-cpu switchticks and switchtime in sched_throw() for the very first context switch on APs during boot. This avoids a small gap between the middle of thread_exit() and sched_throw() where time is not accounted to any thread. - In thread_exit(), update the timestamp bookkeeping to track the changes to mi_switch() introduced by td_rux so that the code once again matches the comment claiming it is mimicing mi_switch(). Specifically, only update the per-thread stats directly and depend on ruxagg() to update p_rux rather than adjusting p_rux directly. While here, move the timestamp bookkeeping as late in the function as possible. Reviewed by: bde, kib MFC after: 1 week Notes: svn path=/head/; revision=229429

| | | | | | | | | | | | | | | | | | | reference on a group in the leaving state while iterating over the loop. Instead, use the same approach used in igmp_ifdetach() and mld_ifdetach() of placing the groups to free on pending release list and then releasing the references after dropping the IF_ADDR_LOCK. This closes an ugly race where the code was dropping the lock in the middle of iterating over the list. It also fixes some additional potential use-after-free bugs since the cancellation routine also applied other changes to the group after dropping the reference. Now those changes are performed before the reference is dropped and the group is potentially freed.
