commit 814bd40070db654d80a16d9f813610cae3b12dd6
Author: jan Iversen <j...@libreoffice.org>
Date: Sun Mar 11 19:05:09 2018 +0100
iOS, calling cpp_vtable_call does not corrupt stack
Changing bl -> b (jump long to jump) allowed cpp_vtable_call
to work without corrumping the stack.
However return still corrumpts the stack.

commit 056bc3cf26e539f4e841aeeecc8f1badff7ddc37
Author: jan Iversen <j...@libreoffice.org>
Date: Sun Mar 11 18:18:57 2018 +0100
iOS, moved privateSnippetExecutor from asm to C function.
move asm code to C as first step towards reducing the asm code.
Since iOS does not permit java/python or anything else than the
compiled C++ code, the throw should be done simpler.
Apart from that this is the first step in solving a stack
corruption problem in the throw code
