-Subject: [PATCH] 	PR middle-end/48973
- 	* expr.c (expand_expr_real_2) <case LT_EXPR>: If do_store_flag
- 	failed and the comparison has a single bit signed type, use
- 	constm1_rtx instead of const1_rtx for true value.
- 	(do_store_flag): If ops->type is single bit signed type, disable
- 	signel bit test optimization and pass -1 instead of 1 as last
- 	parameter to emit_store_flag_force.
-
-	* gcc.c-torture/execute/pr48973-1.c: New test.
-	* gcc.c-torture/execute/pr48973-2.c: New test.
