Since no test suites includede test_server.hrl, there is no need
to have test_server in the include path or code path.

c288ab87 added beam_reorder to move get_tuple_element instructions.
Compiling code such as the following would crash the compiler:
alloc(_U1, _U2, R) ->
V = R#alloc.version,
Res = id(V),
_ = id(0),
Res.
The crash would occur because the following two instructions:
{get_tuple_element,{x,2},1,{x,1}}.
{allocate_zero,1,2}.
were swapped and rewritten to:
{allocate_zero,1,1}.
{get_tuple_element,{x,2},1,{x,1}}.
That transformation is not safe because the allocate_zero instruction
would kill {x,2}, which is the register that is holding the reference
to the tuple. Only do the transformation when the tuple reference is
in an x register with a lower number than the destination register.

The ASN.1 compiler often generates code similar to:
f(<<0:1,...>>) -> ...;
f(<<1:1,...>>) -> ....
Internally that will be rewritten to (conceptually):
f(<<B:1,Tail/binary>>) ->
case B of
0 ->
case Tail of ... end;
1 ->
case Tail of ... end;
_ ->
error(case_clause)
end.
Since B comes from a bit field of one bit, we know that the only
possible values are 0 and 1. Therefore the error clause can be
eliminated like this:
f(<<B:1,Tail/binary>>) ->
case B of
0 ->
case Tail of ... end;
_ ->
case Tail of ... end
end.
Similarly, we can also a deduce the range for an integer from
a 'band' operation with a literal integer.
While we are at it, also add a test case to improve the coverage.

regressions_SUITE will have code snippets which previously crashed the compiler.
This commits includes a test for Maps crash in beam_bool.

If we want to have test cases that run eprof, we must make sure that
there are no modules loaded that don't have a working module_info/1
function, since eprof calls module_info(functions) to retrieve the
list of functions in the module. Some test cases load modules compiled
from Core Erlang that don't have any module_info/1 functions, so
we will need make sure that all such modules have been unloaded.
Add z_SUITE:loaded/1 to run after all other test cases to verify that
all modules that the code server consider loaded are indeed loaded and
all have working module_info/0,1 functions.

For tidiness, always place .core files in data directories.

Added coverage of operating map variable.

It should be beam_except_SUITE, since it tests the beam_except
module (introduced in 726f6e4c7afe8ce37b30eedbebe583e7b9bfc51b).

This test suite has been superseded by other test suites (e.g.
guard_SUITE). Removing it does not decrease the coverage.

In order to save space, rewrite suitable calls to erlang:error/{1,2}
to special BEAM instructions.
This code is probably longer than the code taken out of v3_life and
v3_codegen in the previous commit, but it is much easier to
understand and maintain since the BEAM assembler format is better
understood than the v3_life format.

beam_disasm:file/1 would crash if asked to disassemble a stripped
BEAM file without an "Attr" chunk.

"-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.

Since a function_clause exception in an inlined function will
be changed to a case_clause exception, we must test for both.
|
|
Clone some test suites and compile them with the 'inline' option
to test inlining more thorughly.

The r11 option was used to generate BEAM modules that could
loaded both on both R11 and R12/R13 to facilitate testing
that R11 and R13 nodes could communicate with each other.
Since R14 is only required to be compatible with R12 and
R13 nodes, the r11 option is no longer needed.
