Subject: [PATCH v2 09/11] s390: Clean up s390-linux-tdep.c
Date: Tue, 05 Dec 2017 12:29:00 -0000 [thread overview]
Message-ID: <20171205122859.2919-10-prudo@linux.vnet.ibm.com> (raw)
In-Reply-To: <20171205122859.2919-1-prudo@linux.vnet.ibm.com>
After moving big parts of the code to the new s390-tdep.c file
s390-linux-tdep.c now contains many includes it doesn't need any more.
Further more the code for record-replay is disrupted by some code that does
not belong to the feature.
So clean up the include list and move the code disrupting record-replay to
places where it makes more sense. Also remove some superfluous newlines.
gdb/ChangeLog
* s390-linux-tdep.c: Reorder code.
Remove unneeded includes and order alphabetically.
