i386.c (ix86_print_operand): Remove dead code that tried to avoid (%rip) for call operands.
* config/i386/i386.c (ix86_print_operand): Remove dead code that tried to avoid (%rip) for call operands. * config/i386/i386.c (ix86_print_operand_address_as): Add no_rip argument. Do not use RIP relative addressing when no_rip is set. (ix86_print_operand): Update call to ix86_print_operand_address_as. (ix86_print_operand_address): Ditto. * config/i386/i386.md (*movabs<mode>_1): Use %P modifier for absolute movabs operand 0. Add square braces for -masm=intel. (*movabs<mode>_2): Ditto for operand 1.
