I introduced DECL_BASED_ON_RESTRICT_P because the conversion to SSA discarded
almost all information about restrict qualifiers. The compiler was tracking
restrict qualifiers on the original variable, but not on the GIMPLE

gcc44-pr36013.patch
Patch I've bootstrapped/regtested on x86_64-linux. Will you check this in, or

I'll approve the patch. I think it's correct. I'll check it in in a day or
two, or you can go ahead and do it if you are ready. Thanks for testing it.

if (u TREE_CODE (u) == VAR_DECL DECL_BASED_ON_RESTRICT_P (u))
u = DECL_GET_RESTRICT_BASE (u);
in internal_get_tmp_var looks wrong to me. That together with
find_single_pointer_decl not respecting

The patch didn't come with any testcases, so it is hard to find out what

be on the same level of indirection as some TYPE_RESTRICT
