2009-04-17 Bob Duff <duff@adacore.com> * output.ads (Indent,Outdent): New procedures for indenting the output. (Write_Char): Correct comment -- LF _is_ allowed. * output.adb (Indent,Outdent): New procedures for indenting the output. Keep track of the indentation level, and make sure it doesn't get too high. (Flush_Buffer): Insert spaces at the beginning of each line, if indentation level is nonzero. (Save_Output_Buffer,Restore_Output_Buffer): Save and restore the current indentation level. (Set_Standard_Error,Set_Standard_Output): Remove superfluous "Next_Col := 1;". Flush_Buffer does that. * sem_ch6.adb, sem_ch7.adb (Debug_Flag_C): Reorganize the output controlled by the -gnatdc switch. It now occurs on entry/exit to the relevant analysis routines, and calls Indent/Outdent to make the indentation reflect the nesting level. Add "helper" routines, since otherwise lots of "return;" statements would skip the debugging output. From-SVN: r146253
