No, it doesn't. </blockquote><div><br></div><div>That's right I wanted to say to make that default while you are at it</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">The choice between ARM and Thumb(2) is made by the<br class="gmail_msg">

I'm not aware of any ARMv6 cores which don't support Thumb2. Do you<br class="gmail_msg">
have a reference?<br class="gmail_msg">
<br class="gmail_msg">
(But again, to be clear, this commit doesn't change the default in<br class="gmail_msg">
terms of instruction set - all builds will still use ARM).<br class="gmail_msg">
