dwarf-regs.c includes an arch-specific dwarf-regs-table.h for several architectures. This pulls in different definitions of REG_DWARFNUM_NAME and causes compiler warnings for W=1 builds. In file included from util/dwarf-regs.c:23: .../dwarf-regs-table.h:5: error: "REG_DWARFNUM_NAME" redefined [-Werror] #define REG_DWARFNUM_NAME(reg, idx) [idx] = reg Undefine REG_DWARFNUM_NAME before each new definition.
