I am not sure whether it should in general +# work to mix uses of the (default on Linux, at least) GCC libgcc_s and LLVM's libclang_rt.builtins +# runtime libraries in one process, but for this specific case of libcairo.so it appears to work +# well: For one, the only symbol referenced by libcairo.so from the runtime library is __muloti4; +# for another, at least in my LLVM build, lib/clang/12.0.0/lib/linux/libclang_rt.builtins-x86_64.a +# is only provided as a static archive; so libcairo.so will only contain a "harmless" copy of +# __muloti4 and not have a DT_NEEDED of any libclang_rt.builtins dynamic library that it would pull +# in at runtime. +# But passing -rtlib=compiler-rt into cairo's configure via the more obvious LDFLAGS would fail at +# least when building with -fsanitize=address and -fsanitize=undefined, as then the executable +# compiled by configure when "checking whether the C compiler works" would reference +# _Unwind_Backtrace etc. that are provided by GCC's libgcc_s.so.1 but not by LLVM's +# libclang_rt.builtins-x86_64.a (and whatever the reason for that inconsistency). So +# -rtlib=compiler-rt must be passed just into the linking of libcairo.so, but not generally into +# cairo's configure. And pixman_LIBS happens to offer that.
