eb0b8da6e816 started to use a binary instead of a string in
bs_match_string instructions.
Remove a clause that attempts to handle the old form of
bs_match_string from old .S files. This is pointless, because an old
.S file is likely to contain a bs_context_to_binary instruction as
well. The bs_context_to_binary is no longer recognized by
`beam_validator`, so those old .S files will not work anyway.

With the recent update to cover to use the `counters` modules,
there is no longer any reason to limit the number of parallel
processes when running `cover`.

The function `get_call_order_po/2` did not always include all
functions in a module. The method it used was to first find
all leave functions (functions not calling any other function),
and then find all others functions that called any of the leave
functions either directly or indirectly.
Functions that did not call a leave function (directly or indirectly)
would not be included in the list of functions to optimize.
Reimplement `get_call_order_po/2` to use the standard algorithm
for constructing a list of nodes in reverse postorder and then
reverse that list.

Try calling iolist_size() before calling string:length().
The reason is that calls to string:length/1 are slow when the argument
is not a list of integers (or contains UNICODE).

Fix failing renegotiation testcases with openssl-1.1.1a.
openssl s_client sends the renegotiation "R\n" connected command
to the server side causing testcase failure.
This commit updates ssl_to_openssl_SUITE:erlang_ssl_receive to
swallow the unexpected packet.

This commit fixes failing testcases on OpenBSD 12.0 systems. It
forces openssl s_client to use an IPv4 address if openssl supports
IPv6.
When s_client is called with the argument "localhost" it binds
to the first address returned by getaddrinfo. As the first address
is an IPv6 address on OpenBSD 12.0, the client fails to send
UDP packets to the ssl server that is listening on an IPv4 address.

This change saves about about a minute when running the
cover-compiled compiler tests.

Use `counters:add/3` instead of `ets:update_counter/3`
for counting the number of times a line is executed.
By default, the reference to the counter array for each module will be
stored in a persistent term and retrieved every time a counter is
updated. This makes the compiler test suite with coverage enabled run
*almost* twice as fast (on my computer, in about 6 minutes down from
more than 11 minutes).
To get even more speed, the new `cover:local_only/0` function can be
called to put cover into a mode where the cover-compiled code can only
be run on the local node. In this mode, the cover-compiled modules in
a more efficient way by compiling the counter reference into the
code. This shaves off about one more minute, making the compiler test
suite with coverage enabled run *more than* twice as fast (in about 5
minutes on my computer).

beam_ssa_type: Propagate the 'none' type from calls
|
|
Consider this pseudo code:
f(...) ->
Val = case Expr of
... ->
... ;
... ->
... ;
... ->
my_abort(something_went_wrong)
end,
%% Here follows code that uses Val.
.
.
.
my_abort(Reason) ->
throw({error,Reason}).
The first two clauses in the case will probably provide some
information about the type of the variable `Var`, information
that would be useful for optimizing the code that follows the
case.
However, the third clause would ruin everything. The call
to `my_abort/1` could return anything, and thus `Val` could
also have any type.
294d66a295f6 introduced module-level type analysis, which will in
general keep track of the return type of a local function
call. However, it does not improve the optimization for this specific
function. When a function never returns, that is, when its type is
`none`, it does not propagate the `none` type, but instead pretends
that the return type is `any`.
This commit extends the handling of functions that don't return to
properly handle the `none` type. Any instructions that directly
follows the function that does not return will be discarded, and the
call will be rewritten to a tail-recursive call.
For this specific example, it means that the type for `Val` deduced
from the first two clauses will be retained and can be used for
optimizing the code after the case.
