2010-06-22 Thomas Quinot <quinot@adacore.com> * sem_eval.adb (Find_Universal_Operator_Type): New subprogram to identify the operand type of an operator on universal operands, when an explicit scope indication is present. Diagnose the case where such a call is ambiguous. (Eval_Arithmetic_Op, Eval_Relational_Op, Eval_Unary_Op): Use the above to identify the operand type so it can be properly frozen. * sem_res.adb (Make_Call_Into_Operator): Remove bogus freeze of operand type, done in an arbitrary, possibly incorrect type (the presence of some numeric type in the scope is checked for legality, but when more than one such type is in the scope, we just pick a random one, not necessarily the expected one). * sem_utils.ads, sem_utils.adb (Is_Universal_Numeric_Type): New utility subprogram.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
