Recognize -mno-implicit-float option for x86 as well as ARM. <rdar://13180731> For x86 targets, we've been using the -msoft-float option to control passing the no-implicit-float option to cc1. Since the -mno-implicit-float option is now accepted by the driver, this just makes it work for x86 the same as it does for ARM targets. llvm-svn: 174836

Use -mno-implicit-float by default for kernel/kext code. <rdar://13177960> Apple's kernel engineers have been expecting this behavior even though we've never implemented it before, as far as I can tell. In recent months, clang has gotten better at using vector instructions to optimize memcpy-like operations, and that has exposed problems when vector/floating-point instructions are used in kexts that don't support that. This behavior also matches what Apple's GCC did for PowerPC targets. llvm-svn: 174838

Rename the driver option to -mno-implicit-float, per Eli's suggestion. llvm-svn: 156950
