* sverk/hipe-fix-literal-crc:
erts,hipe,dialyzer: Fix hipe checkum of target runtime system
erts: Change THE_NON_VALUE to not be hard coded in hipe compiler
OTP-12962
OTP-12963
OTP-12964

Main problem:
A faulty HIPE_LITERAL_CRC was not detected by the loader.
Strangeness #1:
Dialyzer should ask the hipe compiler about the target checksum,
not an internal bif.
Strangeness #2:
The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC
checksum.
Solution:
New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent)
HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC.
HIPE_LITERALS_CRC represents values that are assumed to stay constant
for different VM configurations of the same arch, and are therefor
hard coded into the hipe compiler.
HIPE_SYSTEM_CRC represents values that may differ between VM variants.
By default the hipe compiler asks the running VM for this checksum,
in order to create beam files for the same running VM.
The hipe compiler can be configured (with "make XCOMP=yes ...") to
create beam files for another VM variant, in which case HIPE_SYSTEM_CRC
is also hard coded.
ToDo:
Treat all erts properties the same. Either ask the running VM or hard
coded into hipe (if XCOMP=yes). This will simplify and reduce the risk
of dangerous mismatches. One concern might be the added overhead
from more frequent calls to hipe_bifs:get_rts_param.

Add ssh_trpt_test_lib:instantiate/2, ssh_test_lib:default_algoritms/2 and algo_intersection/2
ssh_to_openssh_SUITE uses only algos that sshd and ssh client supports
raised timeout limit in ssh_basic_SUITE:ssh_connect_arg4_timeout
Break out ssh_renegotiate_SUITE from ssh_basic_SUITE
Move std_daemon/4 to ssh_test_lib.erl
Add ssh_algorithms_SUITE
Add ssh_options_SUITE
Add assymetric testing of algorithms
Add openssh tests to ssh_algorithms_SUITE
Remove algo tests from ssh_sftp_SUITE (now in ssh_algorithms_SUITE)
Removed kex algo tests from in ssh_basic_SUITE because they are now in ssh_algorithm_SUITE.
fixed test case ssh_protocol_SUITE:no_common_alg_server_disconnects/1

Add forgotten HIPE_WRAPPER_BIF_DISABLE_GC which
could lead to stack-heap overrun if unlucky with the
yielding during maps:merge when called by native hipe code.

Opaque recursive parameters are expanded faster.
|
|
Expand parameters when needed only.
The opaqueness is removed from types expanded to any().
|
|
|
|
Add more information about the caller of t_from_form(). Instead of
just the module, also provide name of the type, spec, or record where
the type form resides.
|
|
|
|
Instead ask running VM for the value of THE_NON_VALUE,
which is different between opt and debug VM.
Same hipe compiler can now compile for both opt and debug VM.
|
|
|
|
Optimize the case where we are appending to the end of the binary, use
binary syntax to create binaries with room for expansion in the next
loop, instead of using iolist_to_binary which creates a binary of the
exact size and needs to be copied in each loop.
Also remove support the unused Acc as iolists.

hipe/dialyzer: Fix a bug concerning opaque types and keydelete/3
|
|
In 45f469ca0890, the BEAM loader started to use x(1023) as scratch
register for some instructions. Therefore we should not allow
x(1023) to be used in code emitted by the compiler.

When translating guards to Core Erlang, it is sometimes necessary
to add an is_boolean/1 guard test. Here is an example when it is
necessary:
o(A, B) when A or B ->
ok.
That would be translated to something like:
o(A, B) when ((A =:= true) or (B =:= true)) and
is_boolean(A) and is_boolean(B) ->
ok.
The is_boolean/1 tests are necessary to ensure that the guard
fails for calls such as:
o(true, not_boolean)
However, because of a bug in v3_core, is_boolean/1 tests were
added when they were not necessary. Here is an example:
f(B) when not B -> ok.
That would be translated to:
f(B) when (B =:= false) and is_boolean(B) -> ok.
The following translation will work just as well.
f(B) when B =:= false -> ok.
Correct the bug to suppress those unnecessary is_boolean/1 tests.
|
|
We can rewrite more instances of select_val to is_boolean because
it is not necessary that a particular label follows the select_val.
