Author: srhines Date: Fri Mar 4 14:57:22 2016 New Revision: 262742 URL: http://llvm.org/viewvc/llvm-project?rev=262742&view=rev Log: Switch krait to use -mcpu=cortex-a15 for assembler tool invocations.
Summary: Using -no-integrated-as causes -mcpu=krait to be transformed into -march=armv7-a today. This precludes the assembler from using instructions like sdiv, which are present for krait. Cortex-a15 is the closest subset of functionality for krait, so we should switch the assembler to use that instead.
