This is done by allocating stack blocks (henceforth called *stacklets*) and linking them into a doubly linked list. The function prologue is responsible for checking if the current stacklet has enough space for the function to execute; and if not, -call into the libgcc runtime to allocate more stack space. When using ``llc``, -segmented stacks can be enabled by adding ``-segmented-stacks`` to the command -line. +call into the libgcc runtime to allocate more stack space. Segmented stacks are +enabled with the ``"split-stack"`` attribute on LLVM functions. The runtime functionality is `already there in libgcc <http://gcc.gnu.org/wiki/SplitStacks>`_. |
