Cold instructions used to be cooler (less frequently executed),
so it did not seem worthwhile to pack their operands. Now bit
syntax instructions are included among the cold instructions,
and they are frequently used.
|
|
Update the pack engine to safely push literal operands to the pack
stack and to safely pop them back to another code address. That
will allow packing of more instructions.
|
|
The packer had several bugs and limitations. For instance, on
a 32-bit Erlang virtual machine it would gladly pack three
't' values into one word even though it would be not safe.
The rewritten version will be more careful how much it packs
into each word. It will also be able to do packing for more
instructions.
|
|
Having the helper functions for map update knowing all the details
of operands for the instruction will make it difficult to make
improvements such as better packing.
|
|
As a preparation for potentially improving packing in the future,
we will need to make sure that packable types have a defined maximum
size.
The packer algorithm assumes that two 'I' operands can be packed
into one 64-bit word, but there are instructions that use an 'I'
operand to store a pointer. It only works because those instructions
are not packed for other reasons.
Introduce the 'W' type and use it for operands that don't fit in
32 bits.
|
|
The transformations were incorrect.
|
|
I don't remember what they were used for, but they are certainly
no longer used.
|
|
If a type has a size in %arg_size, it should also have
a defined pattern in %bit_type.
|
|
BEAM_WIDE_MASK covered the 16 right-most bits, instead of the 32
right-most bits. This bug will bite us when we'll do more packing in
the future.
This bug has been harmless in the past. It has been used in
test_heap and allocate instructions for the number of heap words
needed. It would be theoretically possible to construct a program
that would need 65536 or more heap words, but it is hard to imagine
a practical use for such a program. (The program would have to build
a tuple or list with at least one variable and the rest of the elements
being literals.)
|
|
Eliminate the variable used for holding which BIF (bsl or bsr).
It seems to improve performance slightly.
|
|
Make it clear to GCC that shift_left_count is initialized.

On macOS 10.13 (High Sierra), disksup cannot grab information
for any disks that use the new APFS file system. The reason
is that the invocation of /bin/df explicitly limits the
type of file systems to show:
/bin/df -i -k -t ufs,hfs
Add 'apfs' to also look at disks with APFS:
/bin/df -i -k -t ufs,hfs,apfs
That also works on older versions of macOS.
An alternative solution would be to use the -l flag to only
show local file systems. However, that would mean that USB
memory sticks would also show up, and it might not be desirable
to monitor them.

Testcase init functions are getting Config from groups and suites
they're not in. Presumably related to the problems worked around in the
parent commit.

The ANSI support doesn't work properly with edlin, the issue can be noticed when you try to use the history of the shell and the prompt prefix has ANSI (https://github.com/elixir-lang/elixir/issues/6448). The problem is that when a `\e` character appears, it handles it like a new line, dropping the buffer before it.
The solution is to always add the `\e` to the buffer like a regular character and handle it when writing the buffer instead.
|
|
|
|
The support is implied by documentation, but wasn't handled in code. Be
consistent in retrieving the address from the sock rather than the
configuration, and in accepting both ip and ifaddr for a local address.

As introduced in commit 1b3b64af and adjusted in commit e0603ba1.
There's nothing client-specific about it, but keep the record format in
the server example for the sake of coverage.
|
|
Previously, a hard-coded atom (read_write) has been used as file owner access permission
in response to ssh_sftp:read_file_info/2 function. With this fix, the actual value of
file owner access permission is added to the returning record. That value is calculated
from file mode value.

|
Prior to this patch, stop_timeout was not configurable
and set to 5 seconds. This patch allows this value
to be configurable, maintaining the 5 seconds timeout
as default.

diameter_traffic_SUITE has four layers of nested groups, so when a
testcase is run it should get Config from four init_per_group plus one
init_per_testcase. This isn't what happens: Config is being accumulated
from several init_per_group in some manner that isn't clear, and the
skip in the parent commit somehow results in growing
test_server_gl:init/1 processes that eventually consume all memory.
Replacing rather than prepending to Config in init_per_group works
around this, but the common_test behaviour seems wrong.

Functions where missing and where without alternatives, and
the functions are available in wxWidgets-3.0.*.
So either I missed it or they where removed for a while in
wxWidgets-2.9 branch, but that should not be used anywhere as
it was only a development branch.

Default values have never worked in extension for PER.
Note that for default values in the root part of SEQUENCE,
giving a value equal to the DEFAULT value, will result in
the same encoding as if asn1_DEFAULT was given. However,
that behavior is not promised by the documentation. The
documentation says that asn1_DEFAULT should be used for
default values. For DEFAULT in extensions, only implement
what the documentation promises and nothing more.
