When passing a huge parameter using the byval mechanism, a long sequence of loads and stores was being generated to perform the copy on the x86 targets if the parameter was less than 4 byte aligned, causing llc to use up vast amounts of memory and time. Use a "rep movs" form instead. PR7170. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118260 91177308-0d34-0410-b5e6-96231b3b80d8 2010-11-04 21:16:46 +00:00			`; RUN: llc < %s`

ARM doesn't support byval yet. XFAIL this test until it does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128891 91177308-0d34-0410-b5e6-96231b3b80d8 2011-04-05 17:16:21 +00:00			`; XFAIL: arm`
