[PING] Re: [PATCH] ARM half-precision floating point, 3/8 (target hooks)

[Sandra Loosemore <sandra at codesourcery dot com>]

Ping!  Can somebody review this patch?  There was quite a bit of discussion 
about whether this was the right approach when I posted it last month, and I 
think the consensus was that this is OK -- at least, I didn't seem to get any 
specific suggestions for things that need fixing.  But, the patch hasn't been 
formally approved by a maintainer.

http://gcc.gnu.org/ml/gcc-patches/2009-04/msg01124.html

I'll be posting revised versions of some of the later pieces of the series to 
address the comments I got on those.

Thanks,

-Sandra
