From 8d7f06359adf0d3da93acec0f0ded9076f54ebdb Mon Sep 17 00:00:00 2001 From: Anton Kolesov Date: Wed, 6 Jul 2016 20:36:49 +0300 Subject: arc: Add GNU/Linux support for ARC ARC Linux targets differences from baremetal: - No support for hardware single instruction stepping. - Different access rules to registers. - Use of another instruction for breakpoints. v2: Changes after Tom's remarks [1] arc-linux-tdep.c - Use true/false instead of TRUE/FALSE. - arc_linux_sw_breakpoint_from_kind (): Break long lines into two. - arc_linux_sw_breakpoint_from_kind (): Remove starting blank line. - Use explicit number evaluation, e.g: if (a & b) -> if ((a & b) != 0) arc-tdep.c - Use explicit number evaluation, e.g: if (a & b) -> if ((a & b) != 0) gdb/configure.tgt - arc*-*-linux*): Remove "build_gdbserver=yes". v3: Changes after Simon's remarks [2] arc-linux-tdep.c - Use "return trap_size" instead of cryptic "return 2". - Removed unnecessary curly braces. - Removed "void" from "_initialize_arc_linux_tdep (void)". v5: Changes after Simon's remarks [3] - Remove unnecessary empty lines. - Replace "breakpoint uses" with "breakpoints use" in a comment. - "return condition;" i.s.o.
