Here is the patch with iterators for instructions and neon_type
attributes. Also fast-math-pr35982.c is changed according to Ira's
comment. I will look at integration with patterns for neon intrinsics
later.

Sorry , it's taken me a while to get to this.

My undertstanding is that the NEON conversions of integer vectors to
floating point always round to nearest - so
Original discussion here:
http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00751.html
This patch enables vector conversions for ARM NEON architecture. In its
current state vectorizer can't handle type conversions in the hottest
loop of libmp3lame on NEON since its backend doesn't have appropriate

Is it just me or has no one else seen this patch on the archives at
gcc-patches@. ?
