Bug ID: 47303
Summary: llvm/lib/IR/DebugInfoMetadata.cpp fails to compile on
sparcv9-sun-solaris2.11
Product: libraries
Version: trunk
Hardware: PC
OS: Solaris
Status: NEW
Severity: normal
Priority: P
Component: Backend: Sparc
Assignee: unassignedbugs at nondot.org
Reporter: ro at gcc.gnu.org
CC: llvm-bugs at lists.llvm.org

preprocessed source and run script
Within roughly the last month a 2-stage RelWithDebInfo build on
sparcv9-sun-solaris2.11
began to fail compiling llvm/lib/IR/DebugInfoMetadata.cpp and
llvm/lib/IR/Metadata.cpp in stage 2.
A Release build works, while a Debug build fails for different reasons.
Both compilations fail with
fatal error: error in backend: Do not know how to scalarize the result of this
operator!

I've tried to reduce the input with creduce, but so far this hasn't gained
much.
I mean to try a reghunt to identify the responsible revision, but that's going
to
take some time.
