* bjorn/floor-ceiling/OTP-13692:
Add math:floor/1 and math:ceil/1
Implement the new ceil/1 and floor/1 guard BIFs
|
|
Add math:floor/1 and math:ceil/1 to avoid unnecessary conversions
in floating point expressions. That is, instead of having to write
float(floor(X)) as part of a floating point expressions, we can
write simply math:floor(X).
|
|
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of
Erlang language). They are guard BIFs because trunc/1 is a guard
BIF. It would be strange to have trunc/1 as a part of the language, but
not ceil/1 and floor/1.

clang will generate smaller code if we avoid reassigning the
reg and freg arrays. That can be easily arranged by passing them
as arguments to process_main().

Ensure that we cannot get any dangling pointers into code that
has been purged. This is done by a two phase purge. At first
phase all fun entries pointing into the code to purge are marked
for purge. All processes trying to call these funs will be suspended
and by this we avoid getting new direct references into the code.
When all processes has been checked, these processes are resumed.
The new purge strategy now also completely ignore the existence of
indirect references to the code (funs). If such exist, they will
cause bad fun exceptions to the caller, but will not prevent a
soft purge or cause a kill of a process having such live references
during a hard purge. This since it is impossible to give any
guarantees that no processes in the system have such indirect
references. Even when the system is completely clean from such
references, new ones can appear via distribution and/or disk.

Besides using two words for 'milliseconds' et. al. they are
also changed from plural to singular.

erts: Align ErtsThrPrgrLaterOp when free'ing tracer
|
|
On Sparc all structs with a double word element in are assumed
to be allocated on a two word boundary. So we have to make sure
that the ErtsThrPrgrLaterOp * points to 8 / 16 byte aligned memory.
As it only costs one word I've done it on all architectures in case
some unknown other arch also needs this.
