Richard Sandiford b6606e46ab [SystemZ] Don't use LOAD and STORE REVERSED for volatile accesses ... Unlike most -- hopefully "all other", but I'm still checking -- memory instructions we support, LOAD REVERSED and STORE REVERSED may access the memory location several times. This means that they are not suitable for volatile loads and stores. This patch is a prerequisite for better atomic load and store support. The same principle applies there: almost all memory instructions we support are inherently atomic ("block concurrent"), but LOAD REVERSED and STORE REVERSED are exceptions. Other instructions continue to allow volatile operands. I will add positive "allows volatile" tests at the same time as the "allows atomic load or store" tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183002 91177308-0d34-0410-b5e6-96231b3b80d8		2013-05-31 13:25:22 +00:00
