2015-01-12Rewrite matching of object definitions using the simplified syntaxBjörn Gustavsson
Rewrite the confusing and buggy matching of an object definition against the simplified syntax. While we are at it, we will also add proper error handling.
2015-01-12Simplify handling of an empty object definitionBjörn Gustavsson
When the parser sees: something SOMETHING ::= {} it has no way of knowing whether 'something' is an value or an object. It depends on how SOMETHING is defined. For example: SOMETHING ::= SEQUENCE {} or SOMETHING ::= CLASS { &id OPTIONAL } Because of that ambiguity, there is no way to avoid a special case when we check an object definition. However, there is no need to invent an entire new checking function for this special case. It is much easier to just pretend that the parser gave us {object,defaultsyntax,[]} and let check_objectdefn/3 check it in the usual way.
2015-01-12Use object_to_check/1 in two forgotten placesBjörn Gustavsson
An #'Externavaluereference'{} may either be a value or an object. In places where objects are expected, we will need to call object_to_check/1 to convert an #'Externavaluereference'{} to an object. It was forgotten in two places.
2015-01-12Refactor code involving calls to get_fieldname_element/3Björn Gustavsson
Refactor and clean up code. While at it, add error handling and test cases. (Also add test cases for the existing values in ValueTest.asn while we are it.) Add support for defining INTEGER constants by extracting fields from objects. Example: int-from-object INTEGER ::= object.&id When extracting values from objects in constraints, only one level of extraction would work. That is, the following would work: SomeName ::= INTEGER (object.&int) but not: SomeName ::= INTEGER (object.&obj.&int)
2015-01-12Check INTEGER values betterBjörn Gustavsson
There is duplicated effort in that validate_integer() checks whether the integer value is valid, and then normalize_integer() does mostly the same work in order to convert the value to an integer. Eliminate the validate_integer() function and incorporate its checks into normalize_integer(). Also produce proper error messages.
2015-01-12Check CLASS names for validityBjörn Gustavsson
Class names must start with an uppercase letter and only contain uppercase letters, digits, or hyphens. The parser will not allow class names that don't start with an uppercase letter, so we don't have to check that.
2015-01-12Add a new test case to test values in ValueTest.asn1Björn Gustavsson
We only tested that ValueTest.asn1 would compile, no that the values were correct.
2015-01-12Use the #objectclass{} record instead of a tupleBjörn Gustavsson
Don't build a record using the tuple syntax. It is bad in case we would want to change the record definition later.

2015-01-09Extend count_bits_matched/3 to handle the UTF instructionsBjörn Gustavsson
While we are, clean up the comments and rearrange the code for clarity. Also add a test to cover the last uncovered line in beam_dead.erl.
2015-01-09misc_SUITE: Cover the exception handling code in beam_deadBjörn Gustavsson
Amend the test suite to call beam_dead as originally intended (and not beam_block), and modify the input data so that the exception will occur within the try ... catch block in function/2.
2015-01-09Generalize optimizations using shortcut_rel_op/4Björn Gustavsson
Better optimizations with less code.
2015-01-09beam_dead: Optimize branches from relational conditionalsBjörn Gustavsson
The BEAM compiler translates code such as: is_hex_digit(D) when $0 =< D, D =< $9 -> true; is_hex_digit(D) when $a =< D, D =< $z -> true; is_hex_digit(D) when $A =< D, D =< $Z -> true; is_hex_digit(_) -> false. to something like this: L0: test is_ge L1 {x,0} 48 test is_ge L1 57 {x,0} move true {x,0} return. L1: test is_ge L2 {x,0} 97 test is_ge L2 122 {x,0} move true {x,0} return L2: test is_ge L3 {x,0} 65 test is_ge L3 90 {x,0} move true {x,0} return L3: move false {x,0} return We can see that tests will be repeated even if they cannot possibly succeed. For instance, if we pass in {x,0} equal to 32, the first test that {x,0} is greater than or equal to 48 at L0 will fail. The control will transfer to L1, where it will be tested whether {x,0} is greater than 97. That test will fail and control will pass to L2, where again the test will fail. The compiler can do better by short-circuiting repeating tests: L0: test is_ge L3 {x,0} 48 test is_ge L1 57 {x,0} move true {x,0} return. L1: test is_ge L2 {x,0} 97 test is_ge L3 122 {x,0} move true {x,0} return L2: test is_ge L3 {x,0} 65 test is_ge L3 90 {x,0} move true {x,0} return L3: move false {x,0} return

These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.
