2014-12-19erts: Make main thread safe from pipe closed eventLukas Larsson
2014-12-19erts: Improve crash dumpsLukas Larsson
This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)
2014-12-19erts: Rename sys_sigset to sys_signalLukas Larsson
Also removed old legacy fallback that is no longer used
2014-12-19erts: Introduce thread suspend functionsLukas Larsson
These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

* maint: Use the new 64-bit atomic ops API Introduce a 64-bit atomic ops API
2014-12-10Use the new 64-bit atomic ops APIRickard Green
2014-12-10Introduce a 64-bit atomic ops APIRickard Green
The 64-bit atomic ops API is implemented by * native word size atomic ops on 64-bit architectures, and * native double word size atomic ops on 32-bit architectures when available. When native double word size atomic is not available, the fallback using modification counters is used.

clang aka llvm claims to be __GNUC__ and thus we have to explicitly check that it is not used.

This has to be done in order to consistently generate the same file so that we do not get rebuilds all the time.

2014-11-24erts: Use finite instead of isfinite with gccLukas Larsson
Turns out that isfinite emits a function call and not an instruction in gcc, this makes estone float arith about 50-75% slower. finite emits the instruction so we use that instead.
