core_lib: Handle patterns in map values

io:put_chars(standard_error, [oops]) could previously crash the
standard_error process.

Parsing invalid 'Set-Cookie' header would make httpc crash.
This commit filters invalid 'Set-Cookie' headers so that httpc wouldn't try to parse them.

core_lib:is_var_used/2 would not consider a variable used in the
value of a map pattern such as:
case Map of
#{key := <<42:N>>} -> ok
end
Here the variable 'N' would not be considered used.
It was assumed that there was no need to check map patterns at
all, since maps currently don't support variables in keys.

{index, [2]} refers to #person.name rather than #person.address, which
caused a little confusion in #erlang today.
{index, [4]} is the correct "hard coded" field for #person.address.

When optimizing boolean expressions, it is not always possible
to find a number of live registers for a GC BIF that both preserves
all source registers that will be tested and at the same time
does not include registers that are not initialized.
As currently implemented, we have incomplete information about
the register calculated from the free variables. Some registers
are marked as "reserved". Reserved registers means that we don't
know anything about them; they may or may not be initialized.
As a conservative correction (suitable for a maintenance release), we
will abort the optimization if we find any reserved registers when
calculating the number of live registers. We will not attempt to
improve the information about the registers in this commit.
By examining the coverage when running the existing compiler test
suite we find that the optimization is aborted 15 times (before
adding any new test cases). To put that in perspective, the
optimization is successfully applied 4927 times, and aborted for
other reasons 547 times.

Old versions of the Erlang mode for Emacs used to indent try...catch
strangely - the first clause following the 'catch' would be indented
with one space less than the following clauses.
If we are to use the new Erlang mode when we add more clauses, they
would be indented with one space less than the preceding clauses.
That would look silly.

The optimization of a 'case' statement could lead to incorrect
code that would cause an exception at run-time.
Here is an example to show how the optimization went wrong. Start
with the following code:
f({r,#{key:=Val},X}=S) ->
case S of
{r,_,_} ->
setelement(3, Val, S)
end.
(The record operations have already been translated to the
corresponding tuple operations.) The first step in case_opt/3 is
to substitute S to obtain:
f({r,#{key:=Val},X}=S) ->
case {r,#{key:=Val},X} of
{r,_,_} ->
setelement(3, Val, S)
end.
After that substitution the 'case' can be simplified to:
f({r,#{key:=Val},_}=S) ->
case #{key:=Val} of
NewVar ->
setelement(3, Val, S)
end.
That is the result from case_opt/3. Now eval_case/2 notices
that since there is only one clause left in the 'case', the
'case' can eliminated:
f({r,#{key:=Val},_}=S) ->
NewVar = #{key:=Val},
setelement(3, Val, S).
Since the map construction may have a side effect, it was not
eliminated, but assigned to a variable that is never used.
The problem is that '#{key:=Val}' is fine as a pattern, but in a
construction of a new map, the '=>' operator must be used. So the
map construction will fail, generating an exception.
As a conservative correction for a maintenance release, we will
abort the 'case' optimization if the substitution into the 'case'
expression is anything but data items (tuples, conses, or
literals) or variables.

release_handler_SUITE:otp_10463_upgrade_script_regexp reads
kernel.appup and tries to fetch upgrade instructions for upgrade from
current version to current version. The point of the test is to see
that release_handler can read an appup with regexps.
In some cases, however, kernel.appup does not support upgrade from
current to current version, since this is not necessary in real
life. Therefore this test is now updated to use a dummy application
(release_handler_SUITE_data/regexp_appup/app1) for this test.

hipe_rtl:phi_remove_pred/2 can produce a #move{} instruction with
floating-point temporaries as operands, even though such moves MUST
be #fmove{} instructions.
Added type checks to the #move{} and #fmove{} constructor and setter
functions to ensure that similar mishaps cannot happen again.
|
|
RTL can produce an #fconv{} instruction with an immediate operand, but
the backends unconditionally access the operand as a temporary. This
results in broken representation in the backends and eventually they
crash.

It seems like the commit 5a3c4668908254ee930c8db2e5cf9741945f9b2b also
broke the incl_dirs option and friends when given as relative paths.
When a cover spec contains a relative path it is looked-up in the
directory with the test results, not in the .cover file directory.
