Where are Functions allocated before the function boxes

FunctionAllocations.md

FunctionNode* Parser<FullParseHandler, Unit>::standaloneFunction

• Has a Function argument, Called from
• FunctionNode* frontend::StandaloneFunctionCompiler<Unit>::parse which has a function argument, called from
• static bool CompileStandaloneFunction which has a function argument. Called from
  • bool frontend::CompileStandaloneGenerator
  • bool frontend::CompileStandaloneAsyncFunction
  • bool frontend::CompileStandaloneAsyncGenerator
    • All of the above CompileStandAlones, plus the below CompileStandAloneFunction are called from CreateDynamicFunction: the function is allocated there. The above three are -only- called from CreateDynamicFunction.
  • bool frontend::CompileStandaloneFunction which has a function argument. Called from
    • JSFunction* FunctionCompiler::finish which allocates the function
    • CompileStandAloneFunction is called from HandleInstantiationFailure, which allocates a JSFunction for when AsmJS compilation fails for some reason.

bool Parser<FullParseHandler, Unit>::skipLazyInnerFunction

• Function comes from RootedFunction fun(cx_, handler_.nextLazyInnerFunction()); I can't quite figure out how this works (how do you get the 'right' lazyInnerFunction, does it matter?) -- is this infix related.

bool Parser<FullParseHandler, Unit>::trySyntaxParseInnerFunction

• Has a function argument, called from
• GeneralParser<ParseHandler, Unit>::functionDefinition which allocates the function

GeneralParser<ParseHandler, Unit>::innerFunction

• Has function argument, called from
  • bool Parser<FullParseHandler, Unit>::trySyntaxParseInnerFunction, has function argument. Called from: See above (GeneralParser<>::functionDefinition)
    • An aside: This happens if we fail to do a syntax parse.
  • bool Parser<SyntaxParseHandler, Unit>::trySyntaxParseInnerFunction, has function argument, called from: see above (GeneralParser<>::functionDefinition)

Parser<FullParseHandler, Unit>::standaloneLazyFunction

• Has function argument called from
• static bool CompileLazyFunctionImpl. Uses Rooted<JSFunction*> fun(cx, lazy->functionNonDelazifying()); as the function
  • Not sure how that works

GeneralParser<ParseHandler, Unit>::synthesizeConstructor

• allocates a new function directly

GeneralParser<ParseHandler, Unit>::fieldInitializerOpt(

• Allocates a new function directly.
