2010-09-09 Ed Schonberg <schonberg@adacore.com> * sem_eval.adb (Is_Same_Value): Two occurrences of the same discriminant cannot be assumed to be the same value because they may refer to bounds of a component of two different instances of a discriminated type. 2010-09-09 Gary Dismukes <dismukes@adacore.com> * checks.adb (Apply_Arithmetic_Overflow_Check): When converting the operands of an operator to the type of an enclosing conversion, rewrite the operator so the conversion can't be flagged as redundant. Remove useless assignments to Typ and Rtyp. 2010-09-09 Eric Botcazou <ebotcazou@adacore.com> * gnat_ugn.texi: Fix another long line. 2010-09-09 Bob Duff <duff@adacore.com> * sem_warn.adb (Output_Reference_Error): Don't warn for renames read but never assigned.
