Hello all,
I am working on project on V8 for which I need to get all the constants in
a JS program. I need to know where the ASTNodes for the constants is
created.
Although, I have got the subclasses of ASTNode like Statement, Expression
etc. I also found the function which creates Literal ASTNode for a number,
"NewNumberLiteral" in AstFactory in ast.h. I entered a simple printf
statement to print the value of the number for which it is making Number
Literal i.e. my code now is
Literal* NewNumberLiteral(double number, int pos, bool with_dot = false) {
::printf("NewNumberLiteral %f %d\n", number, pos);
return new (zone_)
Literal(zone_, ast_value_factory_->NewNumber(number, with_dot), pos
);
Following is the JS file I am executing:
function test( obj ) {
return obj.prop + obj.prop;
}
var a = { prop: 'a' }, i = 10;
i = 12+23;
while ( i < 10000 ) {
test( a );
i = i + 123;
}
Although, the printf statement is printing 12 and 23 and their sum 35 also
(because of the optimization done by v8 which computes the sum).
But I am not getting 10000, 123 and 10 as the output.
Can anyone please tell me where is the another function creating the number
literal. It will be very helpful.
Thank You,
