Test that DTLS handles "high" level packet types as http-packet types.
Low level packet type as {packet, 2} we will consider later if they
should be relevant to support or not.

Eliminate the all-purpose variable 'ires'. Replace it with several
variables used that are used for their specific purpose. Narrow
the scope of the variables.
Do this to improve readability. It is not expected that it should
any impact on performance.

Generated code uses 'I' explicitly in other places, so it
can as well use 'I' when accessing the operands for instructions.
|
|
The beam_instrs.h file serves no useful purpose. Put the
instructions in beam_hot.h instead.
|
|
The type 'd' could be used both for destination registers and
source register.
Restrict the 'd' type to only be used for destinations, and
introduce the new 'S' type to be used when a source must be
a register.

Problems with failure of ssl_certificate_verify_SUITE when enabling DTLS-1
tests in ssl_basic_SUITE was a combination of the bug fixed by the
previous commit and missing clean up code for dtls_protocol_versions
application environment variable
|
|
Only DTLS specific code deals with DTLS version, when common code
is used the DTLS version should be converted to the corresponding TLS version.

The 'I' type can be replaced with 't' if we know that the value
will fit in 16 bits. The 'P' type can be replaced with 'Q' if
it is used for deallocating a stack frame.
|
|
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.
