2003-07-10  Kazu Hirata	 <kazu@cs.umass.edu>

	PR c/11449
	* fold-const.c (sign_bit_p): Return EXP if VAL is the sign bit
	of HOST_WIDE_INT.
	(fold_single_bit_test): If sign_bit_p() fails, assume that the
	bit being tested is not a sign bit.

2003-07-04  Jeff Law  <law@redhat.com>

	PR c/11428
	* expr.c (do_store_flag): Pass in the correct result type
	when calling fold_single_bit_test.
	* fold-const.c (fold_single_bit_test): Use result_type for the
	result when folding a sign bit test.

2003-07-02  Jeff Law  <law@redhat.com>

	* expr.c (do_store_flag): Remove special case folding for
	single bit tests.  Instead call back into the commonized folder
	routine.
	* fold-const.c (fold_single_bit_test): New function, mostly
	extracted from do_store_flag, with an additional case extracted
	from fold.
	(fold): Call fold_single_bit_test appropriately.
	* tree.h (fold_single_bit_test): Prototype.
