Description Sergey Galanov 2012-08-01 10:09:04 PDT 
Created attachment 8981 [details]
Example code

mayLoad and mayStore always return false for INLINEASM instructions, even when there is a memory constraint.
One consequence is that post-RA instruction scheduler builds incorrect graph for an example from attachment (it lacks the required MOV32mr->INLINEASM dependence).
