Dear all,
In order to be able to implement this idea for stores, I think I need
to make some changes to the RTL if-converter such that it will
sometimes add -- to the code being compiled -- a new slot/variable in
the stack frame. This memory needs to be addressable via a pointer
in the code being generated, so AFAIK just allocating a new
pseudo-register won`t work and AFAIK using an RTL "scratch" register
also won`t work. I also want to do my best to ensure that this
memory is thread-local. For those reasons, I`m asking about the
stack.
