Subject: [PATCH v3 1/4] xtensa: clear all DBREAKC registers on start
Date: Wed,  9 Mar 2016 21:29:02 +0300	[thread overview]
Message-ID: <1457548145-1773-2-git-send-email-jcmvbkbc@gmail.com> (raw)
In-Reply-To: <1457548145-1773-1-git-send-email-jcmvbkbc@gmail.com>

There are XCHAL_NUM_DBREAK registers, clear them all.
This also fixes cryptic assembler error message with binutils 2.25 when
XCHAL_NUM_DBREAK is 0:

  as: out of memory allocating 18446744073709551575 bytes after a total
  of 495616 bytes
