From 1031a3a57ed76f5cb8754a89ddb22f3d9ebe8861 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 9 May 2009 17:57:21 +0900 Subject: sh: Provide an __sdivsi3_2 export for sh64. Newer code paths that are heavier in 64-bit math manage to get this generated by newer compilers, provide a definition and export accordingly. This is trivially wrapped around the existing __sdivsi3 code.
