Robert Dewar c800f86287 checks.adb (Determine_Range): Add Assume_Valid parameter 
2009-04-07  Robert Dewar  <dewar@adacore.com>

	* checks.adb (Determine_Range): Add Assume_Valid parameter
	
	* checks.ads (Determine_Range): Add Assume_Valid parameter
	
	* errout.adb (Error_Msg_NEL): Use Suppress_Loop_Warnings rather than
	 Is_Null_Loop to suppress warnings in a loop body.
	
	* exp_ch4.adb:
	(Rewrite_Comparison): Major rewrite to accomodate invalid values
	
	* exp_ch5.adb:
	(Expand_N_Loop_Statement): Delete loop known not to execute
	
	* opt.ads:
	(Assume_No_Invalid_Values): Now set to False, and as documented, this
	 fully enables the proper handling of invalid values.
	
	* sem_attr.adb:
	New calling sequence for Is_In_Range
	
	* sem_ch5.adb:
	(Analyze_Iteration_Scheme): Accomodate possible invalid values
	 in determining if a loop range is null.
	
	* sem_eval.adb:
	(Is_In_Range): Add Assume_Valid parameter
	(Is_Out_Of_Range): Add Assume_Valid_Parameter
	(Compile_Time_Compare): Major rewrite to accomodate invalid values and
	 also to do more accurate and complete range analysis, catching more
	 cases.
	
	* sem_eval.ads:
	(Is_In_Range): Add Assume_Valid parameter
	(Is_Out_Of_Range): Add Assume_Valid_Parameter
	
	* sem_util.adb:
	New calling sequence for Is_In_Range
	
	* sinfo.adb:
	(Suppress_Loop_Warnings): New flag
	
	* sinfo.ads:
	(Is_Null_Loop): Update documentation
	(Suppress_Loop_Warnings): New flag
	
	* gnat_ugn.texi: Document -gnatB switch

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the file 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.html for how to report bugs usefully.
