Claudiu Zissulescu Ianculescu Oct. 5, 2023, 11:43 a.m. UTC 
The '^' was used to print '@' character in the ouput assembly. This is
not anylonger required by the ARC binutils. Remove it.

gcc/

	* config/arc/arc.cc (arc_init): Remove '^' punct char.
	(arc_print_operand): Remove related code.
	* config/arc/arc.md: Update patterns which uses '%&'.

gcc/testsuite/

	* gcc.target/arc/loop-3.c: Update test.
