LONG_LIVED is not thread safe on non-smp and
can only be used by scheduler.

perf counter is now part of the function pointer interface
and also the function returns the value instead of writing
to a memory buffer.

Microstate accounting is a way to track which state the
different threads within ERTS are in. The main usage area
is to pin point performance bottlenecks by checking which
states the threads are in and then from there figuring out
why and where to optimize.
Since checking whether microstate accounting is on or off is
relatively expensive if done in a short loop only a few of the
states are enabled by default and more states can be enabled
through configure.
I've done some benchmarking and the overhead with it turned off
is not noticible and with it on it is a fraction of a percent.
If you enable the extra states, depending on the benchmark,
the ovehead when turned off is about 1% and when turned on
somewhere inbetween 5-15%.

The perf_counter is a very very cheap and high resolution timer
that can be used to timestamp system events. It does not have
monoticity guarantees, but should on most OS's expose a monotonous
time.
A special instruction has been created for this counter to further
speed up fetching it.

ERTS_WRITE_UNLIKELY can be used to place global variables in
a specific section where only data that is very rarely modified
sits. This is used to improve cache locality.

- replace system-specific #ifndef around sigaction() override with a test
for OVERRIDE_SIGACTION, #define or #undef that as appropriate in each
system-specific block
|
|
- move extern declarations of LIBC_SIGACTION() from system-specific
blocks to the common LIBC_SIGACTION block
|
|
- rename __next_sigaction to next_sigaction, to avoid defining _-prefixed symbols
- factor out common code for declaring and initializing next_sigaction,
system-specific code now only needs to #define NEXT_SIGACTION
|
|
- rename __SIGACTION to LIBC_SIGACTION, to avoid defining _-prefixed symbols
|
|
- add block for NetBSD, define dummy INIT() macro
- eliminate ifndef NetBSD around INIT() invocation
|
|
- remove glibc < 2.3 code
- move glibc-2.2 comment to glibc >= 2.3 block
- remove obsolete "only supports" comment
- remove support for broken sigaltstack() in pre-2.4 Linux kernels
