This fixes the PR by making sure CLASSTYPE_AS_BASE types inherit
TYPE_TYPELESS_STORAGE from the main type so that types that inherit
a type with TYPE_TYPELESS_STORAGE also get TYPE_TYPELESS_STORAGE
propagated.

Hi, during testing of the new in-review C-SKY port, we discovered some FAILs
due to
the default va_args gimplifying (targhooks.c:std_gimplify_va_arg_expr) not

While m68k does have branch prediction, it's a dead architecture, does

We were rather sloppy about handling the ownership of prefixes for
pretty_printer, and this lead to a memory leak for any time a
diagnostic_show_locus call emits multiple line spans.
This showed up in "make selftest-valgrind" as:

Hi
Here is a patch to avoid definition of invalid operators on the
Debug mode safe iterator type depending on its category.
Even if it is limited to the Debug mode code I would like to have a
feedback before committing. Especially on the following points:

I don't find anything ugly on it, except the formatting glitches (missing

We should always set cfun->machine->max_used_stack_alignment if the
maximum stack slot alignment may be greater than 64 bits.
Tested on i686 and x86-64. OK for master and backport for GCC 8?
Thanks.

Certainly not every "strlen" has these semantics. For example,
