Subject: Bug 6391

CVSROOT:	/cvs/gcc
Module name:	gcc
Changes by:	sayle@gcc.gnu.org	2003-10-03 21:33:57

Modified files:
	gcc            : ChangeLog fold-const.c tree.c simplify-rtx.c 
	gcc/testsuite  : ChangeLog 
Added files:
	gcc/testsuite/gcc.c-torture/execute: 20031003-1.c 

Log message:
	PR optimization/9325, PR java/6391
	* fold-const.c (fold_convert): For floating point to integer
	conversions, return the maximum/minimum representable integer
	value if the real constant overflows the destination type.
	* tree.c (real_value_from_int_cst): Allow the type to be NULL,
	meaning don't truncate the result to a floating point mode.
	Simplify the logic by calling real_from_integer directly.
	* simplify-rtx.c (simplify_unary_operation):  Implement the
	same semantics for folding floating point to integer conversions
	in RTL.
	
	* gcc.c-torture/execute/20031003-1.c: New test case.
