...there is no documentation on how to pass -enable-tbaa to opt driver. llvmc supports -Wo, option, but the option specified after -Wo, seems to be dropped. Another thing, when using -clang option to llvmc, I got link errors even when -c or -S is specified: clang -x c foo.c -emit-llvm-bc -o /tmp/llvm_JnS1o8/foo.bc (.text+0x20): undefined reference to `main' collect2: ld returned 1 exit status clang: error: linker (via gcc) command failed with exit code 1 (use -v to see invocation) David > > By the way the build instruction in this > > page http://clang.llvm.org/get_started.html ne...

The tests in test/Analysis/TypeBasedAliasAnalysis suggest that at least licm is using it. Also note that lib/Analysis/TypeBasedAliasAnalysis.cpp defines as enable-tbaa option that is off by

Thanks. Just built clang and saw the meta data and annotations on the memory accesses -- is any opt pass consuming the information? By the way the build instruction in this page http://clang.llvm.org/get_started.html needs to be updated -- it recommends config (with default settings) and build llvm in the source dir -- it leaves some 'sticky' generated files in the source dir leading to
