- Segmented stack allows stack space to be allocated incrementally than as a monolithic chunk (of some worst case size) at thread initialization. This is done by allocating stack blocks (henceforth called <em>stacklets</em>) 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. Support for segmented stacks on x86 / Linux is currently being worked on.
+ Segmented stack allows stack space to be allocated incrementally than as a monolithic chunk (of some worst case size) at thread initialization.

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 <tt>llc</tt>, segmented stacks can be enabled by adding <tt>-segmented-stacks</tt> to the command line.

The runtime functionality is <a href="http://gcc.gnu.org/wiki/SplitStacks">already there in libgcc</a>.
