In OTP 20, all Unicode characters are allowed in atoms.
However, we have decided that we will not allow non-latin1
characters in module names in OTP 20. This restriction may
be lifted in a future major release of OTP.
Enforce the restriction in erl_lint, so that it will be a
compilation error to have a module name containing non-latin1
characters. That means that tools such as debugger, xref,
dialyzer, syntax_tools, and so on, do not have to be modified
to handle non-latin1 module names.

Code such as the following:
-record(x, {a}).
f(R, N0) ->
N = N0 / 100,
if element(1, R#x.a) =:= 0 ->
N
end.
would fail to compile with the following message:
m: function f/2+19:
Internal consistency check failed - please report this bug.
Instruction: {fmove,{fr,0},{x,1}}
Error: {uninitialized_reg,{fr,0}}:
This bug was introduced in 348b5e6bee2f.
Basically, the beam_type pass placed the fmove instruction in the
wrong place. Instructions that store to floating point registers and
instructions that read from floating point registers are supposed to
be in the same basic block.
Fix the problem by flushing all floating points instruction
before a call the pseudo-BIF is_record/3, thus making sure that
the fmove instruction is placed in the correct block.
Here is an annotated listing of the relevant part of the .S
file (before the fix):
{test_heap,{alloc,[{words,0},{floats,1}]},2}.
{fconv,{x,1},{fr,0}}.
{fmove,{float,100.0},{fr,1}}.
fclearerror.
{bif,fdiv,{f,0},[{fr,0},{fr,1}],{fr,0}}.
{fcheckerror,{f,0}}.
%% The instruction {fmove,{fr,0},{x,1}} should have
%% been here.
%% Block of instructions expanded from a call to
%% the pseudo-BIF is_record/3. (Expanded in a later
%% compiler pass.)
{test,is_tuple,{f,3},[{x,0}]}.
{test,test_arity,{f,3},[{x,0},2]}.
{get_tuple_element,{x,0},0,{x,2}}.
{test,is_eq_exact,{f,3},[{x,2},{atom,x}]}.
{move,{atom,true},{x,2}}.
{jump,{f,4}}.
{label,3}.
{move,{atom,false},{x,2}}.
{label,4}.
%% End of expansion.
%% The fmove instruction that beam_validator complains
%% about.
{fmove,{fr,0},{x,1}}.

The bug in Dialyzer is fixed in commit 5ac2943.
|
|
The following calls:
- otp_internal:obsolete(rpc, safe_multi_server_call, 2).
- otp_internal:obsolete(rpc, safe_multi_server_call, 3).
threw an unhandled exception.
The return value has been amended to match the relevant pattern of
obsolete/3.
|
|
|
|
Users wanted to see the maximum value seen by observer during it's uptime.
Note changes faster than the sample rate will still be missed.
|
|
In OTP-20 dirty_schedulers are default on.
Draw them dotted so we can difference between real schedulers
and dirty schedulers.
