+# 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
+#
