            Bug ID: 22897
           Summary: Make codegen tests more robust
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org
          Reporter: qcolombet at apple.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

A lot of our codegen tests just check that some instructions are generated and
do not check that the actual operands are corrects.

In the past year, this lack of coverage has led us in at least three nasty bugs
(fixed in r232085, r208252, and r209324), that would have been caught right
away with those checks.

We should fix that situation.
