-# This patch contains various fixes for the thumb code handling in GCC 3.4.4
-#
-# Most of these are minor fixes to code which is either missing (Linux thumb
-# div0, thumb clear instruction cache) or uses the wrong return mechanism
-# (libffi)
-#
-# There is also a significant design problem with the _call_via_rx code -
-# it cannot be in a shared library because a call via PLT simply won't
-# work (for _call_via_ip) and is very inefficient anyway.
-#
-# This is fixed in uclibc simply by incorporating the code into crti.S
-# (an extra 30 bytes for the 15 functions) even though not all link units
-# require all the code - there is so little of it. That doesn't work with
-# the crti.asm here because it is linked with libgcc.a which already defines
-# these symbols
-#
