Set the mtriple in some tests so that they use AAPCS. llvm-svn: 106041 2010-06-16 04:42:00 +08:00			`; RUN: llc < %s -mtriple=arm-linux-gnueabi`
Don't setCalleeSavedInfoValid() until spills are interted. In a naked function, the flag is never set and getPristineRegs() returns an empty list. That means naked functions are able to clobber callee saved registers, but that is the whole point of naked functions. This fixes PR4716. llvm-svn: 79096 2009-08-15 21:10:46 +08:00			`; PR4716`

Remove the arm_aapcscc marker from the tests. It is the default for the linux targets. llvm-svn: 106029 2010-06-16 03:04:29 +08:00			`define void @_start() nounwind naked {`
