Author: pirama Date: Fri Jul 1 19:05:42 2016 New Revision: 274409 URL: http://llvm.org/viewvc/llvm-project?rev=274409&view=rev Log: Add TargetInfo for 32-bit and 64-bit RenderScript
Summary: The TargetInfo for 'renderscript32' and 'renderscript64' ArchTypes are subclasses of ARMleTargetInfo and AArch64leTargetInfo respectively. RenderScript32TargetInfo modifies the ARM ABI to set LongWidth and LongAlign to be 64-bits. Other than this modification, the underlying TargetInfo base classes is initialized as if they have "armv7" and "aarch64" architecture type respectively.
