The original test comes from the emulator test suite for testing
binary syntax in the run-time system.
Running interpreted it can be quite slow, especially when the system
has been compiled with the configure option --enable-native-libs
(probably because of very many context switches between native code
and BEAM code).
Speed up the test by scaling down the size of binaries from 128
bits to 64 bits. That should speed up the test roughly four times.
By running the little and big endian tests in parallel we will
cut that time in half. Thus all in all the test will run roughly
8 times faster.

Truly test debugger in erl_eval_SUITE copy

The module was not interpreted.
This surfaced two bugs, related to shadowed variables in binary patterns in
comprehension generators, and guard filters not properly detected. The guard
detection code from dbg_iload is deleted in favor of erl_lint:is_guard_test/1.
The erl_lint module is now safe to use because it can handle all expressions
emitted by sys_pre_expand, the following warning is thus obsolete and has been
removed from code:
%% Cannot use erl_lint here as sys_pre_expand has transformed source.

While working on a tool that processes Erlang code and testing it against this repo,
I found out about those little sneaky 0xff. I thought it may be of help to other
people build such tools to remove non-conforming-to-standard characters.

This complements 933e701 (OTP-10209). Without this patch the test cases
"in_guard/1" and "coerce_to_float/1" in bs_construct_SUITE fail.
The added lines in bs_construct_SUITE cover all branches that were not
covered before (small and big numbers if BIT_OFFSET(erts_bin_offset) != 0).

This complements 933e701 (OTP-10209). Without this patch the test case
"bs_match_misc_SUITE:t_float/1" fails.
Simple error example:
1> <<_,_,_,_,_,_,_,_>> = <<1.25/float>>.
<<63,244,0,0,0,0,0,0>>
2> <<1.25/float>> = <<63,244,0,0,0,0,0,0>>.
** exception error: no match of right hand side value <<63,244,0,0,0,0,0,0>>
The additional test case is added because in a former version of this
patch the ERTS_FP_ERROR_THOROUGH check for NaN/infinity was mistakenly
applied on the still word-switched double.

Some bit syntax test cases take much longer time to complete when
libraries are in native code, probably because of context switches
between the eval_bits module and the debugger modules.

Currently, the external fun syntax "fun M:F/A" only supports
literals. That is, "fun lists:reverse/1" is allowed but not
"fun M:F/A".
In many real-life situations, some or all of M, F, A are
not known until run-time, and one is forced to either use
the undocumented erlang:make_fun/3 BIF or to use a
"tuple fun" (which is deprecated).
EEP-23 suggests that the parser (erl_parse) should immediately
transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have
not followed that approach in this implementation, because we
want the abstract code to mirror the source code as closely
as possible, and we also consider erlang:make_fun/3 to
be an implementation detail that we might want to remove in
the future.
Instead, we will change the abstract format for "fun M:F/A" (in a way
that is not backwards compatible), and while we are at it, we will
move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)"
from sys_pre_expand down to the v3_core pass. We will also update
the debugger and xref to use the new format.
We did consider making the abstract format backward compatible if
no variables were used in the fun, but decided against it. Keeping
it backward compatible would mean that there would be different
abstract formats for the no-variable and variable case, and tools
would have to handle both formats, probably forever.

This commit is a preparation for introducing location information
(filename/line number) in stacktraces in exceptions. Currently
a stack trace looks like:
[{Mod1,Function1,Arity1},
.
.
.
{ModN,FunctionN,ArityN}]
Add a forth element to each tuple that can be used indication
the filename and line number of the source file:
[{Mod1,Function1,Arity1,Location1},
.
.
.
{ModN,FunctionN,ArityN,LocationN}]
In this commit, the fourth element will just be an empty list,
and we will change all code that look at or manipulate stacktraces.
|
|
The stacktrace in debugger-generated exceptions should be
as similar to stacktraces in BEAM-generated exceptions as
possible.

'eval_bits' is a common utility module used for evaluting binary
construction and matching. The functions that do matching
(match_bits/{6,7} and bin_gen/6) are supposed to treat the bindings as
an abstract data type, but they assume that the bindings have the same
representation as in the erl_eval module. That may cause binary
matching to fail in the debugger, because the debugger represents the
bindings as an unordered list of two-tuples, while the erl_eval
modules uses an ordered list of two-tuple (an ordset).
One way to fix the problem would be to let the debugger to use ordered
lists to represent the bindings. Unfortunately, that would also change
how the bindings are presented in the user interface. Currently, the
variable have most been recently assigned is shown first, which is
convenient.
Fix the matching problem by mending the leaky abstraction in
eval_bits. The matching functions needs to be passed two additional
operations: one for looking up a variable in the bindings and one for
adding a binding. Those operations could be passed as two more funs
(in addition to the evaluation and match fun already passed), but the
functions already have too many arguments. Therefore, change the
meaning of the match fun, so that the first argument is the operation
to perform ('match', 'binding', or 'add_binding') and second argument
is a tuple with arguments for the operation.

A long time ago, test suites were copied from other applications.
Copy the tests again to get more test cases.

"-f" is a non-standard chmod option which at least SGI IRIX and HP UX do
not support. As the only effect of the "-f" flag is to suppress warning
messages, it can be safely omitted.
