Description :

Shared libraries functions store their entire state in a struct, in a pattern similar to that of the attached code.

It would be convenient to have a way to specify that while *ctx_p is computed \from *ctx_p, the pointer field(s) are used only by address and should not pollute the integer fields.

Currently:

$ ~/ppc/bin/toplevel.opt -val modular.c … [value] Values at end of function main: ctx ? {{ garbled mix of &{ctx} (origin: Misaligned {modular.c:21}) }} y ? {{ garbled mix of &{ctx} (origin: Misaligned {modular.c:21}) }}
