             Bug #: 14502
           Summary: Stuff inside operator new should be evaluated first
           Product: clang
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: LLVM Codegen
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: wenhan.gu at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Hi all,

When we write "new B(XXX)",
Clang CodeGen will emit 1) "operator new B" first, then 2) "XXX", finally 3)
done the argument preparation and call the "constructor B".

However, we should get 2) -> 1) -> 3).

This does matter when "operator new of B" assumes it will be executed *after*
the argument inside.
