The autoimport_SUITE:autoimport/1 test case would interpret
data type definitions as function calls. Fix this by skipping
to the <funcs> tag before starting to collect function names.

In the half-word emulator, smp emulator, and non-smp emulator
the X register and float register arrays were allocated in
different ways.
Always allocate the registers and store the pointers to the
allocated register arrays in the scheduler data.

In commit be8759e68b337524c056b8bb757ea68c9996d863, a buffer overflow
was fixed in erlc and the erlc_SUITE:arg_overflow/1 test case was
added. That test cases invokes erlc with 10000 -D options, which will
result in 'erl' being invoked with more than 30000 arguments.
On some platforms, the test case will fail for the wrong reason:
* 64-bit Linux kernels before 2.6.23 limit the number of arguments in
an excvp() call to 16383. (See "Number of arguments and maximum length
of one argument" in http://www.in-ulm.de/~mascheck/various/argmax/.)
* The command shell in Windows limits the size of the command line to
8191 characters.
Depending on the platform, pass a different number of -D options
to erlc. Since the size of the options does not matter for this
test case, make the options as short as possible by generating
numbers in base 36.

Update documentation and specifications of some of the zlib functions
Conflicts:
erts/preloaded/ebin/zlib.beam

The functions zlib:deflateSetDictionary/2 and zlib:inflateSetDictionary/2
accept iodata() as Dictionary.
The functions zlib:crc32/2,3, zlib:adler32/2,3, zlib:compress/1,
zlib:uncompress/1, zlib:zip/1, and zlib:unzip/1 accept iodata() as
data.

In 64bits machines the Sint type has a size of 8 bytes,
while on 32bits machines it has a 4 bytes size.
enif_compare was ignoring this and therefore returning
incorrect values when the result of the CMP function
(which returns a Sint value) doesn't fit in 4 bytes.
For example, passing the operands -1294536544000 and
-1178704800000 to enif_compare would trigger the bug.

Add erlang:check_old_code/1 to quickly check whether a module
has old code. If there is no old code, there is no need to call
erlang:check_process_code/2 for all processes, which will save
some time if there are many processes.
|
|
There is no need to suspend the process if the module has no old
code. Measurements show that this change will make
erlang:check_process_code/2 in an SMP emulator about four times
faster if the module has no old code.

Put the actual saving of the continuation pointers on the stack
in the new function erts_save_stacktrace() so that it can be reused.
The code is too tricky and complicated to allow it to
become duplicated.

|
|
|
As a preparation for providing information about the source
location for an MFA item in an exception stacktrace, refactor
the code that builds the exception stacktrace. Basically we
need two passes over the saved continuation counters: a first
pass to calculate the needed heap space and a second pass to
actually build the stacktrace.
