I'm toying with building with -mdynamic-no-pic, but for this to work, the shared library bits in llvm can't be built with that flag.

...: they > should generally all be built pic. After reviewing yet more of the Makefile,rules file, I believe ENABLE_PIC is the right thing to check. Currently ENABLE_PIC has to be set to get shared bits built, if the user wants them. Given that, we can use that to control wether or not -mdynamic-no-pic is added. Because this _must_ be set, it is safe to use the setting of that flag to make the decision on wether to add -mdynamic-no-pic. If that flag isn't set, the resulting objects, in general, can't be used in a shared library. > This is because we don't know h...

Hi Mike, If you're doing this for Clang's benefit, I think the best thing to do is to compile LLVM PIC (the default) and then build the clang front- end pieces with -mdynamic-no-pic....

Hi, If you create an Xcode project with cmake -G Xcode ~/llvm and do a build, you end up with 68 warnings like this: -mdynamic-no-pic overrides -fpic or -fPIC This can be easily avoided doing: cmake -G Xcode -ULLVM_ENABLE_PIC ~/llvm But I think it would be nicer if it built warning-free with the simpler form. What do you think? Ray PS: CMake generated make style builds on Mac OS X don't use the - mdyna...

Thought a bit more. There's also -mdynamic-no-pic.
