* bjorn/bs-zero-width-bug/OTP-8997:
Fix type-checking of variable used in zero-width bit syntax construction
|
|
<<A:0>> will always produce an empty binary, regardless of the
type of A. The bug is in the run-time system. Fix it so that a
non-numeric value for A will cause a badarg exception.

all references to the table before deallocating it.

* rickard/load-balance-wrap/OTP-8950:
Prevent wrapping of values used during load balancing
|
|
Some integer values used during load balancing could
under rare circumstances wrap causing a load unbalance
between schedulers.
|
|
|
|
Also corrected compressed files on Windows
|

The compressed format is using a slighty modified variant of the extern format
(term_to_binary). To not worsen key lookup's too much, the top tuple itself
and the key element are not compressed. Table objects with only immediate
non-key elements will therefor not gain anything (but actually consume one
extra word for "alloc_size").

* rickard/cpu-groups/OTP-8861:
Generalize reader groups
Move cpu topology functionality into erl_cpu_topology.[ch]
Do not use more reader groups for schedulers than schedulers
Conflicts:
erts/emulator/beam/erl_init.c
|
|
Reader groups have been generalized to cpu groups which can be
used for implementing reader groups, but also for implementing
other functionality in the future.
|
|
|
|
When the runtime system had fewer schedulers than logical processors,
the system could get an unnecessarily large amount reader groups.

* rickard/sys_schedule_debug:
