* sverker/round-bug/OTP-14227:
erts: Fix round/1 for large floats
|
|
1> round(6209607916799025.0).
6209607916799026
Problem: Adding/subtracting 0.5 and large double floats between
(1 bsl 52) and (1 bsl 53) does not give reliable results.
Solution: Use round() function in math.h.

Magic references are *intentionally* indistinguishable from ordinary
references for the Erlang software. Magic references do not change
the language, and are intended as a pure runtime internal optimization.
An ordinary reference is typically used as a key in some table. A
magic reference has a direct pointer to a reference counted magic
binary. This makes it possible to implement various things without
having to do lookups in a table, but instead access the data directly.
Besides very fast lookups this can also improve scalability by
removing a potentially contended table. A couple of examples of
planned future usage of magic references are ETS table identifiers,
and BIF timer identifiers.
Besides future optimizations using magic references it should also
be possible to replace the exposed magic binary cludge with magic
references. That is, magic binaries that are exposed as empty
binaries to the Erlang software.

* josevalim/atu8-chunk/PR-1078/OTP-14178:
Add new AtU8 beam chunk
|
|
The new chunk stores atoms encoded in UTF-8.
beam_lib has also been modified to handle the new
'utf8_atoms' attribute while the 'atoms' attribute
may be a missing chunk from now on.
The binary_to_atom/2 BIF can now encode any utf8
binary with up to 255 characters.
The list_to_atom/1 BIF can now accept codepoints
higher than 255 with up to 255 characters (thanks
to Björn Gustavsson).

The BIF process_info(Pid, current_stacktrace) truncates the
stacktrace. The old behavior was to truncate long stacktraces to max
8 items. And this was hard coded. Now it is truncated to the value of
system_flag(backtrace_depth) instead. The backtrace_depth defaults to
8, but is configurable.

|
In time_SUITE, the univ_to_local/1 and local_to_univ/1 test cases will
fail if they are run outside the CET timezone. The consistency/1
test case uses is not reliable in March and October because it
uses a simplified model for when the switch to/from DST is done.

Monitor first, then ask to terminate.
