Hi, for gcc.dg/tree-ssa/alias-access-path-13.c to work, SRA must think of accesses to foo.inn.val and to foo itself as different ones, i.e. they need to have different offset and size, which on 32bit platforms they do not. Fixed by replacing a dummy long int field of the union with a struct of two integers. Tested by: make -k check-gcc RUNTESTFLAGS="tree-ssa.exp=alias-access-path-13.c" and make -k check-gcc RUNTESTFLAGS="--target_board=unix'{-m32}' tree-ssa.exp=alias-access-path-13.c" on an x86_64-linux, also with patched SRA to verify it still tests the original intent. I hope the fix is obvious enough (and it is only a testsuite change) that I can commit it myself.
