[LLVMdev] strict aliasing and LLVM
Is type based aliasing implemented in LLVM? Simple test case shows it is
not, or an option similar to -fstrict-aliasing is needed?
Thanks,
David

It is being implemented. You have to use clang, not llvm-gcc. The
types are encoded as metadata. Compile with -OX and and look for the
TBAA metadata in the .ll file.
