Change-Id: Ie3a761cf006249b30d0691d1ea167d69a012c36a Signed-off-by: Mathias K <[email protected]> Reviewed-on: http://openocd.zylin.com/367 Tested-by: jenkins Reviewed-by: Spencer Oliver <[email protected]> which added the cast, as part of also supporting accesses of sizes other than 32 bits. Assuming that the code worked earlier, it seems that the input parameter "buffer" will be correctly aligned anyway. But I guess it's not guaranteed, or gcc would not complain. So if read_mem32() is to be kept and used, then the calling code must also work with a buffer which is guaranteed to be aligned properly. Possibly not so trivial to fix. //Peter ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ OpenOCD-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/openocd-devel
