[Bug tree-optimization/17884] [4.0 Regression] asm 'volatile' is not honored as documented

If I read you correctly, first you say:
"volatile does not behave as a NOP because it *does* guarantee that the stmt will
not be removed unless it is unreachable".
And then:
" I dont beleive we delete ASM of any sort unless they are unreachable".

So, question remains. what does 'volatile' do to an asm in gcc-4.0?
