            Bug ID: 15925
           Summary: llvm-mc failed to calculate expressions like K*K-K*2-1
           Product: tools
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvmc
          Assignee: unassignedbugs at nondot.org
          Reporter: lei.wang.left at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Constant expressions formed as K*K-K*2-1, where K is a Symbol standing for a
constant number, are evaluated incorrect by llvm-mc. Here is an example:
K=5
A=K*K-K*2-1
llvm-mc will output A = 16, which is incorrect.
