|

| 4 | 1. 'Finally' clause is not called when exit is encountered
|
|---|
| 5 |
|
|---|
| 6 | ----------------------------------------------------------------------
|
|---|
| 7 | 2. Optimisation causes incorrect code.
|
|---|
| 8 | Compiler optimisation often generates incorrect code for expressions.
|
|---|
| 9 | Must be turned off in most programs. This makes Sibyl somewhat slow
|
|---|
| 10 | for intensive calculations
|
|---|
| 11 |
|
|---|
| 12 | ----------------------------------------------------------------------
|
|---|
| 13 | 3. Internal errors.
|
|---|
| 14 | ( see 9 for one example )
|
|---|
| 15 |
|
|---|
| 16 | ----------------------------------------------------------------------
|
|---|
| 17 | 4. Allowed to construct abstract classes
|
|---|
| 18 | - ?
|
|---|
| 19 |
|
|---|
| 20 | ----------------------------------------------------------------------
|
|---|
| 21 | 5. Compiler and resource compiler won't open readonly source files.
|
|---|
| 22 |
|
|---|
| 23 | ----------------------------------------------------------------------
|
|---|
| 24 | 6. Resource compiler includes files, relative to current dir, not current file path.
|
|---|
| 25 | - Fixed in Fp4
|
|---|
| 26 |
|
|---|
| 27 | ----------------------------------------------------------------------
|
|---|
| 28 | 7. No quick way to append to AnsiString
|
|---|
| 29 | Need to optimise s:= s + 'blah'; like delphi, or make a procedure
|
|---|
| 30 | ? Perhaps with optimisation on, this would be done?
|
|---|
| 31 |
|
|---|
| 32 | ----------------------------------------------------------------------
|
|---|
| 33 | 8. .rc files are not included in make
|
|---|
| 34 | (Same as Delphi ;-( )
|
|---|
| 35 |
|
|---|
| 36 | ----------------------------------------------------------------------
|
|---|
| 37 | 9. IDE compiler crashes if command line compiler used while IDE running.
|
|---|
| 38 | (On units that the IDE project is using)
|
|---|
| 39 | "Internal compiler error" or "Undefined identifier: TForms.CreateWnd!O7272!"
|
|---|
| 40 |
|
|---|
| 41 | ----------------------------------------------------------------------
|
|---|
| 42 | 10. Cannot pass nil as a value for procedure/function/method variable parameters
|
|---|
| 43 | For example:
|
|---|
| 44 |
|
|---|
| 45 | TDoBob = procedure of object;
|
|---|
| 46 | Procedure DoABobFunction( Function: TDoBob );
|
|---|
| 47 | ...
|
|---|
| 48 |
|
|---|
| 49 | DoABobFunction( nil )
|
|---|
| 50 | crashes.
|
|---|
| 51 |
|
|---|
| 52 | ----------------------------------------------------------------------
|
|---|
| 53 | 11. Functions nested inside class methods generate faulty references to self
|
|---|
| 54 | The nested function can refer to properties/methods of the class it is in
|
|---|
| 55 | the method of, but the code crashes.
|
|---|
| 56 | Workaround: refer to self explicitly.
|
|---|
| 57 |
|
|---|
| 58 | ----------------------------------------------------------------------
|
|---|
| 59 | 12. Make does not notice "implicit" dependencies
|
|---|
| 60 | e.g. ArchiveStore contains TRevision. Interace changes.
|
|---|
| 61 | CachedArchive uses ArchiveStore
|
|---|
| 62 | FIlelistArchive uses elements of revision via an array property but does not ave ArchiveStore in Uses
|
|---|
| 63 |
|
|---|
| 64 | ----------------------------------------------------------------------
|
|---|
| 65 | 13. Produces corrupt debug data in Publics section on large projects
|
|---|
| 66 | - On large projects the IDE cannot debug with a message like:
|
|---|
| 67 | Debugger Error: 'Object 387 in module D:...newview.exe
|
|---|
| 68 | not found (PUBLICS)'
|
|---|
| 69 | The end of the publics table is garbage.
|
|---|
