I'm using Visual C++ 2005 for building applications for ARM,开发者_如何学JAVA Qualcomm Snapdragon chip. I know it supports VFPv3. Where can I get SDK or something like to use floating-point arithmetics hardware? Best of all if Visual C++ compiler would generate VFP instructions instread of emulating.
Try /QRfpe-
compiler option. It will Enable Hardware Floating Point Targeting. But I don't know, is it present in VS2005 - the document is about VS 2008 compiler.
And I'm not sure VFPv3 is supported. Maybe it supports some earlier VFP version.
Other way is to use different compiler, e.g. RealView ARM Compiler and it's optimized libs.
