Re: [fpc-devel] How to manually control debug information
I'm writting a custom preprocessor and I would like that the line number information maps to the original file. An example (not real, only an example): ...original.pas... 21 procedure AddFive(var a, b: Integer); 22 begin 23 a := ++b; 24 end; After preprocessor: ...processed.pas... 25 procedure AddFive(var a, b: Integer); 26 begin 27 Inc(b); 28 a := b; 29 end; I would like that stepping in the debugger through AddFive showed original.pas in lines 21 to 24, not processed.pas in lines 25 to 29. How could I do that? If you have a preprocessor, you will also need a binary postprocessor to edit the linenumbers. IOW the preprocessor should keep track that original.pas:21 becomes processed.pas:25, and your binary postprocessor should parse all stabs and patch these occurances. Maybe you need a few dummy units with the same names as the included ones to create entries for these units. However a binary postprocessor is a bit complicated. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
