Hi,
I have no preference in tune feature coding. But I agree with you it's better
to
put similar things together. I modified the code following your suggestion.
Is it OK to commit this modified patch?

Fixes two pph BOGUS bugs which now result in an asm diff.
Tested with bootstrap build and pph regression testing.

We were only streaming the first field of every struct. Struct fields have a
chain link to the next field, thus we need to stream the DECL_CHAIN of every
field as well recursively.
I limited this to VAR_DECL and FUNCTION_DECL for now (which fixes all of our
current bugs in regards to the struct

Hi!
On the huge testcase in the PR we ICE, because GC needs too deep recursion.
I've noticed that part of the problem is deep recursion through
TYPE_NEXT_VARIANT pointers.
As TREE_CHAIN on types is TYPE_STUB_DECL, therefore should point
to a different kind of tree and thus isn't really a pointer t

Hi!
This patch introduces a new extension, to hint the compiler
that a pointer is guaranteed to be somehow aligned (or misaligned).
It is designed as a pass-thru builtin which just returns its first
argument, so that it is more obvious where we can assume how it is aligned.
Otherwise it is similar

Hi,
this is yet another variant of the fix. This time we stream builtins decls as

builtin decls used by folders. Not sure if it is any better than breaking

This pragma can be easily handle in a MELT function, giving the operator
