Summary: UndefValue::get() returns the same value
Product: libraries
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Core LLVM classes
AssignedTo: unassignedbugs at nondot.org
ReportedBy: viridia at gmail.com
CC: llvmbugs at cs.uiuc.edu
I thought that the way UndefValue::get() was supposed to work is that it
returned a different instance each time you called get() - but what I am seeing
is that if I call multiple times with the same type, it returns the same
object.
I realize that I could be misunderstanding how UndefValue is supposed to work
in the new type system - one difficulty that I've been having a lot lately is
that when something breaks, I don't know whether the breakage is intentional or
not.
However, the current behavior doesn't seem very useful, and breaks a lot of my
code. I normally use UndefValue to create placeholders in constants which will
be filled in later, but with the current behavior all placeholders are the
same.
