(i386_get_debug_register_length): Likewise. (TARGET_HAS_DR_LEN_8): Use above macro. (i386_show_dr): Use debug_printf instead of puts_unfiltered and printf_unfiltered. Use phex to format values. gdb/gdbserver/ 2014-06-18 Gary Benson * i386-low.c (i386_get_debug_register_length): New macro. (TARGET_HAS_DR_LEN_8): Remove conditional. Use above macro. (i386_show_dr): Use debug_printf instead of fprintf. Use phex to format values. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index c6de90e..2754c61 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,13 @@ 2014-06-18 Gary Benson + * i386-nat.c (debug_printf): New macro. + (i386_get_debug_register_length): Likewise. + (TARGET_HAS_DR_LEN_8): Use above macro. + (i386_show_dr): Use debug_printf instead of puts_unfiltered + and printf_unfiltered.
