This is needed as doing only an 'exit' will only exit the
program, but any children started in the program that have
stdout/stderr still open will keep the port open until they
terminate. i.e.
os:cmd("while true; do echo sleep 1; sleep 1; done&").
would block os:cmd forever because the while loop keeps its copies
of stdout/stderr open forever.
It could be argued that this is correct behaviour, and it is
the way it works on windows, but changing this breaks backwards
compatability for os:cmd which is not acceptable.

beam_block: Fix potentially unsafe optimization in move_allocates/1
|
|
beam_block has an optimization that only is safe when it is applied
immediately after code generation. That is pointed out in a comment:
NOTE: Moving allocation instructions is only safe because it is done
immediately after code generation so that we KNOW that if {x,X} is
initialized, all x registers with lower numbers are also initialized.
That assumption may not be true after other optimizations, such as
the beam_utils:live_opt/1 optimization.
The new beam_reorder pass added in OTP 19 runs before beam_block.
Therefore, the optimization is potentially unsafe. The optimization
is also unsafe if compilation is started from assembly code in a
.S file.
Rewrite the optimization to make it safe. See the newly added comment
for details.

This speeds up the compilation of binary literals
with string values in them. For example, compiling
a file with a ~340kB binary would yield the following
times by the compiler:
Compiling "foo"
parse_module : 0.130 s 5327.6 kB
transform_module : 0.000 s 5327.6 kB
lint_module : 0.011 s 5327.8 kB
expand_module : 0.508 s 71881.2 kB
v3_core : 0.463 s 11.5 kB
Notice the increase in memory and processing time
in expand_module and v3_core. This happened because
expand_module would expand the string in binaries
into chars. For example, the binary <<"foo">>, which
is represented as
{bin, 1, [
{bin_element, 1, {string, 1, "foo"}, default, default}
]}
would be converted to
{bin, 1, [
{bin_element, 1, {char, 1, $f}, default, default},
{bin_element, 1, {char, 1, $o}, default, default},
{bin_element, 1, {char, 1, $o}, default, default}
]}
However, v3_core would then traverse all of those
characters and convert it into an actual binary, as it
is a literal value.
This patch addresses this issue by moving the expansion
of string into chars to v3_core and only if a literal
value cannot not be built. This reduces the compilation
time of the file mentioned above to the values below:
Compiling "bar"
parse_module : 0.134 s 5327.6 kB
transform_module : 0.000 s 5327.6 kB
lint_module : 0.005 s 5327.8 kB
expand_module : 0.000 s 5328.7 kB
v3_core : 0.013 s 11.2 kB
