Summary: Xcode 4.0's llvm-gcc can't bootstrap gcc 4.6.0 or
trunk
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: howa...@nitro.med.uc.edu
While Xcode 4.0's clang can bootstrap FSF gcc trunk and 4.6.0, the llvm-gcc
compiler can not. The bootstrap fails as...

While this is likely a bug in llvm-gcc, we should attempt to analyze it and
file the appropriate radar bug reports against llvm-gcc in case Apple switches
to llvm-gcc as the system compiler in the future.
