From: Paul Fertser Date: Sat, 6 Jul 2013 07:09:44 +0000 (+0400) Subject: aice: fix FTBFS on ARM X-Git-Tag: v0.8.0-rc1~374 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f65f42e16fb9088d1d3c76a8d52f41730f6bffe6;p=openocd aice: fix FTBFS on ARM This fixes a bunch of errors like this: aice_usb.c: In function 'aice_pack_htdc': aice_usb.c:63:4: error: cast increases required alignment of target type [-Werror=cast-align] Compile-tested only. I think this can be seen as another justification for an ARM Jenkins build target. Also, the aice code I've seen so far seems to be assuming it runs on a little-endian machine so probably there're some endianness issues hiding. Hsiangkai, please get an old PowerPC Mac (or at least some fast usb-equipped MIPS SOHO WiFi AP/router for which you can cross-compile OpenOCD with OpenWrt) and do some real-life testing for your code on Big-Endian. I propose it to be a requirement for any non-trivial code submitted by a commercial entity of reasonable size.
