In the code below / with fpc 3.2

function TDwarfInformationEntry.ReadName(out AName: PChar): Boolean;
var
   AttrData: TDwarfAttribData;
begin
   PrepareAbbrev;
   if dafHasName in FAbbrev^.flags then begin
     Result := GetAttribData(DW_AT_name, AttrData);
     assert(Result and (AttrData.InformationEntry = Self),
'TDwarfInformationEntry.ReadName');
     Result := ReadValue(AttrData, AName);
   end
   else
   if (dafHasAbstractOrigin in FAbbrev^.flags) and PrepareAbstractOrigin
then
     Result := FAbstractOrigin.ReadName(AName)    //
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
   else
     Result := False;
end;

components\fpdebug\fpdbgdwarfdataclasses.pas
line 2875

The indicate line says "fpdbgdwarfdataclasses.pas(2870,30) Warning: Function result variable does not seem to be initialized" And I get the warning 5 times.

I also get one (just one) such warning on:
- the "begin" line of the function
- the "PrepareAbbrev" line (which is a call to a procedure)

This appears to be, due to the function being marked "inline". If I remove the "inline" then the warning goes.

Unrelated:

I also get the obvious
fpdbgdwarfdataclasses.pas(2887,30) Note: Call to subroutine "function TDwarfInformationEntry.ReadName(out AName:PChar):Boolean;" marked as inline is not inlined

Of course a call to the function itself is not inlined..... (Well yes, it could be a few times, like loop unroll / but does that warrant a warning?)

Another strange "not inline warning"

All marked as inline
Implementation code of Some is first, then Bar, then FOo. So all code is known,when needed.

Foo => Bar => Some

Bar compiles without warning. So I guess Some was inlined Foo gives a warning. But it warns that "Some is not inlined"

Does that mean, that Bar got inlined in Foo, but that it was not the Bar that inlined Some, but a Bar that did not?

No problem, if the compiler would decide to inline / not inline in whatever way.
But maybe if the message is referring to such nested warnings, then it should indicate that?

real code is
function TDwarfInformationEntry.IsAddressInStartScope(AnAddress:
TDbgPtr): Boolean;
