Adding the ability to turn on Clang analyzer support in the Lagom build.
Right now the following are working warning free on the LibJS test suite:
-DENABLE_MEMORY_SANITIZER:BOOL=ON
-DENABLE_ADDRESS_SANITIZER:BOOL=ON
The following analyzer produces errors when running the LibJS test suite:
-DENABLE_UNDEFINED_SANITIZER:BOOL=ON
Introduce support for the both of these Math methods.
Math.trunc is implemented in terms of Math.ceil or Math.floor
based on the input value. Added tests as well.
This change implements floating point mod based on the algorithm
used in LibM's fmod() implementation. To avoid taking a dependency
on LibM from LibJS I reimplemented the formula in LibJS.
I've incuded some of the example MDM test cases as well.
This surfaced and issue handling NaN which I've fixed as well.
Address the FIXME in MathObject::max to handle an arbitrary
number of arguments. Also adding a test case to verify the
behavior of Math.max() while I'm here.
This patch adds support in the parser and interpreter for this:
var a = 1, b = 2, c = a + b;
VariableDeclaration is now a sequence of VariableDeclarators. :^)
The Lexer and AST already have all the functionality required in place,
so this is just updating Parser::match_secondary_expression() and
Parser::parse_expression() to handle TokenType::{Ampersand,Pipe,Caret},
as well as adding some tests.
This adds Function::construct() for constructor function calls via `new`
keyword. NativeFunction doesn't have constructor behaviour by default,
ScriptFunction simply calls call() in construct()
This adds:
- A global Date object (with `length` property and `now` function)
- The Date constructor (no arguments yet)
- The Date prototype (with `get*` functions)
Fix the "instanceof" operator to check if the constructor's prototype
property occurs anywhere in the prototype chain of the instance object.
This patch also adds Object.setPrototypeOf() to make it possible to
create a test for this bug.
Thanks to DexesTTP for pointing this out! :^)
This operator walks the prototype chain of the RHS value and looks for
a "prototype" property with the same value as the prototype of the LHS.
This is pretty cool. :^)
NewExpression mostly piggybacks on the existing CallExpression. The big
difference is that "new" creates a new Object and passes it as |this|
to the callee.
Unary expressions parsing now respects precedence and associativity of
operators. This patch also makes `typeof` left-associative which was
an oversight.
Thanks to Conrad for helping me work this out. :^)
We were interpreting "undefined" as a variable lookup failure in some
cases and throwing a ReferenceError exception instead of treating it
as the valid value "undefined".
This patch wraps the result of variable lookup in Optional<>, which
allows us to only throw ReferenceError when lookup actually fails.
