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)
|
|
Also removed old legacy fallback that is no longer used
|
|
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.

erts: Fix finite warning for clang

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

When configuring erts to support dynamic trace via dtrace, be sure to clean
up the temporary file "erts/foo-dtrace.h" used to help check for dtrace
support. Otherwise, it shows up as an untracked file in git.
|
|
This has to be done in order to consistently generate the same
file so that we do not get rebuilds all the time.

Don't use both HAVE_SYSTEMD_DAEMON and HAVE_SYSTEMD_SD_DAEMON - use only
the former one and remove the latter one entirely.

erts: Use finite instead of isfinite with gcc

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.
