...How do they build their frontend? Do they use LLVM as an external library? In that case, LLVM_ENABLE_PEDANTIC should not affect them at all. If their frontend is integrated on the LLVM cmake build system, they can switch off -pedantic (on svn LLVM) putting this at the top of their CMakeLists.txt: llvm_replace_compiler_option(CMAKE_CXX_FLAGS, "-pedantic" "") llvm_replace_compiler_option(CMAKE_C_FLAGS, "-pedantic" "")

Ah! Think I figured it out -- it's rtti. When I build with -fno-rtti, the spurious symbol disappears. Blargh, that was complicated. I'm going to try an out-of-source cmake build now. So far this has been a soliloquy, hope it helps someone else. ________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] on behalf of Charles Jacobsen
