Rewrite contracts as statements.
Declare result variable lazily.
Decide if attributes for this function can be inferred from examining the function body.
Check that the function contains any closure. If it's @nogc, report suitable errors. This is mostly consistent with FuncDeclaration::needsClosure().
Check parameters and return type of D main() function. Issue error messages.
Check that this function type is properly resolved. If not, report "forward reference error" and return true.
In the current function, we are calling 'this' function. 1. Check to see if the current function can call 'this' function, issue error if not. 2. If the current function is not the parent of 'this' function, then add the current function to the list of siblings of 'this' function. 3. If the current function is a literal, and it's accessing an uplevel scope, then mark it as a delegate. Returns true if error occurs.
Check all return statements for a function to verify that returning using NRVO is possible.
Creates and returns the hidden parameters for this function declaration.
find function template root in overload list
Find index of function in vtbl[0..dim] that this function overrides. Prefer an exact match to a covariant one.
Resolve forward reference of function signature - parameter types, return type, and attributes. Returns false if any errors exist in the signature.
Resolve forward reference of function body. Returns false if any errors exist in the body.
Determine lexical level difference from this to nested function fd.
Determine lexical level difference from this to nested function fd. Issue error if this cannot call fd.
Determine if function's variables are referenced by a function nested within it.
Returns true if function was declared directly or indirectly in a unittest block
Initialize for inferring the attributes of this function.
Override so it can work even if semantic() hasn't yet been run.
Determine if function needs a static frame pointer.
See if pointers from function parameters, mutable globals, or uplevel functions could leak into return value.
Determine if function is a non-static member function that has an implicit 'this' expression.
See if pointers from function parameters, mutable globals, or uplevel functions could leak into type t.
Determine partial specialization order of 'this' vs g. This is very similar to TemplateDeclaration::leastAsSpecialized().
Merge into this function the 'out' contracts of all it overrides. 'out's are AND'd together, i.e. all of them need to pass.
Merge into this function the 'in' contracts of all it overrides. 'in's are OR'd together, i.e. only one of them needs to pass.
Look at all the variables in this function that are referenced by nested functions, and determine if a closure needs to be created for them.
Find function in overload list that exactly matches t.
Overload this FuncDeclaration with the new one f. Return true if successful; i.e. no conflict.
Find function in overload list that matches to the 'this' modifier. There's four result types.
If function a function in a base class, return that base class.
Determine if 'this' overrides fd. Return !=0 if it does.
Labels are in a separate scope, one per function.
The function is doing something that may allocate with the GC, so mark it as not nogc (not no-how).
The function is doing something impure, so mark it as impure. If there's a purity error, return true.
The function is doing something unsafe, so mark it as unsafe. If there's a safe error, return true.
for diagnostics, e.g. 'int foo(int x, int y) pure'
Generate a FuncDeclaration for a runtime library function.
Determine whether an 'out' contract is declared inside the given function or any of its overrides.
set if this is a known, builtin function we can evaluate at compile time
local variables in this function which are referenced by nested functions (They'll get put into the "closure" for this function.)
1 if there's a return exp; statement 2 if there's a throw statement 4 if there's an assert(0) 8 if there's inline asm 16 if there are multiple return statements
not set before the glue layer
supplied by the user
Outer variables which are referenced by this nested function (the inverse of closureVars)
Sibling nested functions which called this one
if !=NULL, then this is the type of the 'introducing' function this one is overriding
set if someone took the address of this function
Issue an error if an attempt to call a disabled method is made
Check to see if declaration can be modified in this context (sc). Issue error if not.
