[cfe-commits] [patch] Don't mark libc++ functions as always_inline in debug mode.

Really, even if libc++ is bug-free, it'll confuse users if debugging
it in -O0 mode produces strange line jumps.

If NDEBUG is the wrong macro, would it make sense to provide a
LIBCXX_DEBUG flag to move the inlining decisions to clang?
