sys_core_fold could do unsafe transformations on the
code from the old inliner (invoked using the compiler
option `{inline,[{F/A}]}` to request inlining of specific
functions).
To explain the bug, let's first look at an example that
sys_core_fold handles correctly. Consider this code:
'foo'/2 =
fun (Arg1,Arg2) ->
let <B> = Arg2
in let <A,B> = <B,Arg1>
in {A,B}
In this example, the lets can be completely eliminated,
since the arguments for the lets are variables (as opposed
to expressions). Since the variable B is rebound in the
inner let, `sys_core_fold` must take special care when
doing the substitutions.
Here is the correct result:
'foo'/2 =
fun (Arg1, Arg2) ->
{Arg2,Arg1}
Consider a slight modifictation of the example:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg2]
in let <A,B> = <B,[Arg1]>
in {A,B}
Here some of the arguments for the lets are expressions, so
the lets must be kept. sys_core_fold does not handle this
example correctly:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg2]
in let <B> = [Arg1]
in {B,B}
In the inner let, the variable A has been eliminated and
replaced with the variable B in the body (the first B in
the tuple). Since the B in the outer let is never used,
the outer let will be eliminated, giving:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg1]
in {B,B}
To handle this example correctly, sys_core_fold must
rename the variable B in the inner let like this to
avoid capturing B:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg2]
in let <NewName> = [Arg1]
in {B,NewName}
(Note: The `v3_kernel` pass alreday handles those examples correctly
in case `sys_core_fold` has been disabled.)

Add more `compiler_generated` attributes to avoid spurious compiler
warnings triggered by the bug fix in the next commit.

Before this fix an error in io:put_chars/2 would signal
a fault in io:put_chars/3 because of the way that raise is
used and there is no such function.

If scheduler_data is not set correctly on normal schedulers
the code in erts_schedule_time_break and possibly others
will trigger asserts.

The -Woverspecs (-Wspecdiffs) option generates warnings in a few more
cases. The refinement is analogous to the test that -Wunderspecs
already does: it checks if the contract has nothing in common with
some element (see erl_types:t_elements/1) of the success typing.

corrected spelling reffering -> referring
|
|
We want to prepare the code for more advanced DTLS usage and possibility
to run over SCTP. First assumption was that the demultiplexer process
"dtls listener" was needed for UDP only and SCTP could be made more TLS
like. However the assumption seems not to hold. This commit prepares
for customization possibilities.
