Chihong, I notice that IEEE-754-2008 does in fact define a 16-bit floating point standard now, does your processor conform to that standard, if so there should be no objection to adding fp16 to LLVM and you should have no problem using it, at least that's what I think Chris is t...

...p16 support, otherwise those users will suffer from the merging problem with their local LLVM with native fp16 type they add (locally). So we should either add full fp16 support as a basic floating point type or enhance the LLVM infrastructure to make floating point type as scalable as int type. -Chihong -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Chris Lattner Sent: Monday, March 21, 2011 11:26 AM To: Anton.Lokhmotov at arm.com Cc: llvmdev at cs.uiuc.edu Subject: Re: [LLVMdev] [PATCH] OpenCL half support On Mar 21, 2011, a...

Hi, You might want to try running -loops -loop-simplify before loop unroll. >From loop simplify.cpp This pass performs several transformations to transform natural loops into a00011 // simpler form, which makes subsequent analyses and transformations simpler and00012 // more effective.
