Summary: EquivalenceClasses::ECValue's private constructor is
inaccessible when combined with a rvalue reference
aware STL.
Product: libraries
Version: trunk
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: enhancement
Priority: P5
Component: Support Libraries
AssignedTo: [email protected]
ReportedBy: [email protected]

EquivalenceClasses::ECValue has an implicit, private constructor which ends up
getting called in the following places:
include/llvm/ADT/EquivalenceClasses.h:193
include/llvm/ADT/EquivalenceClasses.h:206
Rvalue reference versions of set::find and set::insert will be used to forward
the arguments rather than force the construction of the ECValue type within the
EquivalenceClasses members. This is meant to be a performance optimization
because it results in less constructions of ECValue. The fix which results in
the same behavior as today is to explicitly call the ECValue constructor when
passing the value to both methods above.
