Subject: [PATCH 2/4] x86-dregs: Print debug registers one per line
Date: Wed, 21 Jun 2017 20:15:00 -0000	[thread overview]
Message-ID: <1498076108-29914-3-git-send-email-simon.marchi@ericsson.com> (raw)
In-Reply-To: <1498076108-29914-1-git-send-email-simon.marchi@ericsson.com>

This get around this warning given by clang...

  /home/emaisin/src/binutils-gdb/gdb/nat/x86-dregs.c:209:7: error: variable 'i' is incremented both in the loop header and in the loop body [-Werror,-Wfor-loop-analysis]
        i++;
        ^
  /home/emaisin/src/binutils-gdb/gdb/nat/x86-dregs.c:199:32: note: incremented here
    ALL_DEBUG_ADDRESS_REGISTERS (i)
                               ^

... I decided in the end to simply print the debug registers one per
line.  I don't think it particularly helps readability to have them two
per line anyway.

gdb/ChangeLog:

	* nat/x86-dregs.c (x86_show_dr): Print registers one per line.
