/* Logically, we like to think of the stack as a contiguous region of
|
|
|
|
|
memory. Unfortunately, this logical view doesn't work for the
|
|
|
|
|
register backing store, because the RSE is an asynchronous engine and
|
|
|
|
|
because UNIX/Linux allow for stack-switching via sigaltstack(2).
|
|
|
|
|
Specifically, this means that any given stacked register may or may
|
|
|
|
|
not be backed up by memory in the current stack. If not, then the
|
|
|
|
|
backing memory may be found in any of the "more inner" (younger)
|
|
|
|
|
stacks. The routines in this file help manage the discontiguous
|
|
|
|
|
nature of the register backing store. The routines are completely
|
|
|
|
|
independent of UNIX/Linux, but each stack frame that switches the
|
|
|
|
|
backing store is expected to reserve 4 words for use by libunwind. For
|
|
|
|
|
example, in the Linux sigcontext, sc_fr[0] and sc_fr[1] serve this
|
|
|
|
|
purpose. */
