complete/1 is used when encoding open types (as well as in the
encode/2 function in a generated module).
The use of complete/1 for encoding open types used to be optimized
in two different places.
One place was in the alignment optimization pass, where we attempted
to replace the call to complete/1 with a call to iolist_to_binary/1.
That optimization was taken out in a previous commit that introduced
the {list,_,_} intermediate instruction.
The other place was when creating the intermediate representation
for the encoding of the open type. When attempting to wrap primitive
types in an open type, we would attempt to optimize the encoding of
the length decscriptor. We will remove that optimization in this
commit.
Since the previous two optimizations did not optimize encoding of
open types as much as we would want, we will introduce a new
optimization in a separate pass that will go further than the
previous optimizations.

The {list,List,Dst} instruction gives us as general way to
capture the building of something into a variable. That will make
inlining of intermediate code much easier.
It also allows us to eliminate the versions of the apply, call_gen,
and cond instructions that takes a target variable.
Also remove the optimization in the alignment optimization pass
that attempts to replace calls to complete/1 with calls to
iolist_to_binary/1. That optimization will not work anymore without
rewriting, so we will remove it in this commit and introcude a
more powerful optimization in a future commit.

Instead of generating:
{assign,Dst,"element(2, Val)"}
generate:
{call,erlang,element,[2,{var,"Val"}],Dst}
The latter expression is easier to understand since there is no
need to parse a string which may contain an arbitrary expression.
While at it, also discontinue the practice to treat "naked"
atoms as variables. A variable must always be given as {var,String}.
|
|
The {assign,Dst,Src} instruction is difficult to cope with when
doing advanced optimizations, since its source argument is a string
which may contain any expression.
Instead of changing how {assign,_,_} works, we will introduce new
instructions that can be used instead of {assign,_}, and remove
{assign,_,_} in a later commit when it is no longer used.
The first new instruction we will introduce is:
{set,{var,Src},{var,Dst}}
It is useful for common sub-expression elemination among other things.
For the moment, we will only allow a variable as a source argument,
but we could extend it in the future to allow constants as well.

To facilitate inlining of apply calls in the intermediate format.
|
|
It will greatly facilitate further optimizations if we include the
intermediate code (if available) in the call_gen tuple.

Make sure that we don't construct:
{cons,{integer,I},{cons,{binary,B},T}} - OR -
{cons,{binary,B},{cons,{integer,I},T}}
but:
{cons,{binary,[{put_bits,I,8,[1]}|B]},T} - OR -
{cons,{binary,B++[{put_bits,I,8,[1]}]},T}

The function name could contain hyphens or other characters not
allowed in non-quoted function names.

WxWidgets (used by the wx application) also uses zlib. To
ensure that the run-time system and WxWidgets use the same version
of zlib, use the system's zlib if present.
Also, the system's zlib may be specially optimized and thus faster
than our own generic source code.
We only use zlib versions that are "good enough". For now, that
means 1.2.5 or higher.
Remove the option --enable-shared-zlib and add the option
--enable-builtin-zlib to force the use of the built-in zlib.

Because 26940a8c0c lifted code in the 'after' clause of 'try' to
a new function, Dialyzer could produce false warnings for code such
as:
try
...
after
file:close(F)
end.
Mark the the call to the generated function as 'compiler_generated'
to silence the warning.

This is not a clean refactor. It changes the behaviour slightly
of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used
as-is and not copied into default_stack. This will hopefully fix an
illusive memory leak that valgrind is reporting.

When inserting skeletons in emacs, some Erlang language elements such as
case, receive, and if statements, are not indented properly. This patch,
written by Leo Liu, corrects the indentation problems.

wxWakeUpIdle doesn't always work on wxGTK and the workaround is to
periodically invoke it, so the gui-thread doesn't get stuck in poll.
Previously it was only called when NOT in batch mode, however if the
wxWakeUpIdle call after a batch_begin command did not wake up the
thread it would still get stuck in poll.

Case expressions such as:
case {Expr1,Expr} of
{V1,V2} -> ...
end
are already optimized to not actually build the tuple. Generalize
the optimization to avoid building any kind of composite term,
such as:
case {ok,[A,B]} of
{ok,[X,Y]} -> ...
end
We don't expect programmers to write such code directly, but
inlining can produce such code.
We need to be careful about the warnings we produce. If the case
expression is a literal, it is expected that no warnings should be
produced for clauses that don't match. We must make sure that we
continue to suppress those warnings.

Passing cpu_topology or scheduler_bind_type to erlang:system_flag/2 results
in an error report warning that the argument is deprecated and is slated
for removal in erts-5.10/OTP-R16. Since we're already past that version and
no substitute approach has yet been decided for these features, keep the
deprecation warning but bump the removal version it mentions up to Erlang
18.
