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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@174060 138bc75d-0d04-0410-961f-82ee72b054a4
