Move "atomic" and "volatile" designations on instructions after the opcode of the instruction. Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. llvm-svn: 137527 2011-08-13 00:50:01 +02:00			`; RUN: opt < %s -instcombine -S \| grep {store volatile}`
don't delete the last store to an alloca if the store is volatile. llvm-svn: 50390 2008-04-29 06:58:38 +02:00
