* hb/dialyzer/opaque_parms/OTP-12866:
dialyzer: Correct the handling of parameters of opaque types
|
|
Prior to this commit, the fact that parameters of opaque types are
expanded differently depending on the current values of limits used
during expansion, caused problems later when the types of parameters
are used for determining if opaque types are comparable.

Currently there is no plans in modernizing/changing the API so there
is no real value of pointing out alternative solutions.
|
|
|
|
Remove legacy inet6fb4 option from documentation even if
the code will still accept it.
|
|
Functions in the same module can be referenced as #Function-Arity, no
need to make special markers for them.

Caused stack corruption leading to VM crash on windows.
{packet,ssl_tls} is undocumented by the way.

We'll need a way to limit the size of the crash report produced
by proc_lib:format(). Add format/3, where the third argument is
a depth argument.
|
|
Add the possibility to truncate big messages to avoid running out
of memory.
|
|
Refactor, simplify, and modernize the code to facilitate future
improvements in the following commits.

A long time ago, errors from the emulator itself was sent as
messages that would end up in the handle_info/2 function.
Those clauses in handle_info/2 can be removed.
The code for handling events tagged 'info' instead of 'info_msg'
can also be taken out.
|

|
The test case did not test the log files were created. And they
were not created, because filelib:ensure_dir/1 was used
incorrectly.
|
|
Report handlers are not automatically removed. That means
that the report handler will remain installed until the entire
running of the stdlib test suite finishes. That could potentially
cause problems.
|
|
The unzip_to_binary/1 and zip_to_binary/1 test cases need the
test_server's priv_dir to be empty. On Windows, file system
pecularities can prevent us from emptying priv_dir.
Since the point of this test case is not to test file operations
on Windows, simplify things by working in a newly created sub
directory of priv_dir.

dialyzer: Fix erlang:abs/1
|

Instruction get_map_elements might destroy target registers when the fail-label is taken.
Only seen for patterns with two, and only two, target registers.
Specifically: we copy one register, and then jump.
foo(A,#{a := V1, b := V2}) -> ...
foo(A,#{b := V}) -> ...
call foo(value, #{a=>whops, c=>42}).
corresponding assembler:
{test,is_map,{f,5},[{x,1}]}.
{get_map_elements,{f,7},{x,1},{list,[{atom,a},{x,1},{atom,b},{x,2}]}}.
%% if 'a' exists but not 'b' {x,1} is overwritten, jump {f,7}
{move,{integer,1},{x,0}}.
{call_only,3,{f,10}}.
{label,7}.
{get_map_elements,{f,8},{x,1},{list,[{atom,b},{x,2}]}}.
%% {x,1} (src) is read with a corrupt value
{move,{x,0},{x,1}}.
{move,{integer,2},{x,0}}.
{call_only,3,{f,10}}.
The fix is to remove 'opt_moves' pass for get_map_elements instruction
in the case of two or more destinations.

of a process with a matchstate on the stack.
|
|
If the process stack contained a match state
the print function would crash the vm as it was not
recognized by tag_val_def().
Add new MATCHSTATE_DEF returned by tag_val_def().
All other callers either ignore it or has a default
clause to handle invalid terms.

* 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.
