Add warn_if_not_aligned attribute
Add warn_if_not_aligned attribute as well as command line options:
-Wif-not-aligned and -Wpacked-not-aligned.
__attribute__((warn_if_not_aligned(N))) causes compiler to issue a
warning if the field in a struct or union is not aligned to N:
typedef unsigned long long __u64
__attribute__((aligned(4),warn_if_not_aligned(8)));
struct foo
{
int i1;
int i2;
__u64 x;
};
__u64 is aligned to 4 bytes. But inside struct foo, __u64 should be
aligned at 8 bytes. It is used to define struct foo in such a way that
struct foo has the same layout and x has the same alignment when __u64
is aligned at either 4 or 8 bytes.
Since struct foo is normally aligned to 4 bytes, a warning will be issued:
warning: alignment 4 of 'struct foo' is less than 8
Align struct foo to 8 bytes:
struct foo
{
int i1;
int i2;
__u64 x;
} __attribute__((aligned(8)));
silences the warning. It also warns the field with misaligned offset:
struct foo
{
int i1;
int i2;
int i3;
__u64 x;
} __attribute__((aligned(8)));
warning: 'x' offset 12 in 'struct foo' isn't aligned to 8
This warning is controlled by -Wif-not-aligned and is enabled by default.
When -Wpacked-not-aligned is used, the same warning is also issued for
the field with explicitly specified alignment in a packed struct or union:
struct __attribute__ ((aligned (8))) S8 { char a[8]; };
struct __attribute__ ((packed)) S {
struct S8 s8;
};
warning: alignment 1 of 'struct S' is less than 8
This warning is disabled by default and enabled by -Wall.

[RS6000] PR 80938, Don't emit frame info for regs that don't need saving
It is possible when using out-of-line register saves or store multiple
to save some registers unnecessarily, for example one reg in the block
saved might be unused. We don't need to emit frame info for those
registers as that just bloats the info, and also can result in an ICE
when shrink-wrap gives multiple paths through the function saving
different sets of registers. Join points need to have identical frame
register save state regardless of the path taken.
This patch reverts the previous fix for PR80939 "Use SAVE_MULTIPLE
only if we restore what it saves (PR80938)" and instead fixes the PR
by correcting the frame info. The change to rs6000_savres_strategy
is an optimization, but note that it hides the underlying problem in
the PR testcase.

simplifies the eh_return handling. The intent of
https://gcc.gnu.org/ml/gcc-patches/2010-09/msg01838.html was to say
the PIC reg needed to be saved for eh_return, not all gprs. Of

as that is what the target-independent code does by setting DF live,
but it's unnecessary in the backend.

Limit SH strncmp inline expansion (PR target/78460).
GCC mainline built for sh4-linux-gnu runs out of memory building a
glibc test, which calls strncmp with very large constant size
argument, resulting in the SH inline strncmp expansion trying to
inline a fully unrolled expansion of strncmp for that size.
This patch limits that fully unrolled expansion to the case of less
than 32 bytes. This is explicitly *not* trying to be optimal in any
way (very likely a lower threshold makes sense), just to limit enough
to avoid the out-of-memory issue in the glibc testsuite.
I have *not* run the GCC testsuite for SH. I have verified that this
allows the glibc testsuite to build OK, with both GCC mainline and GCC
7 branch (and that the included test builds quickly with patched GCC,
runs out of memory with unpatched GCC).

[PR79542][Ada] Fix ICE in dwarf2out.c with nested func. inlining
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79542 reports an ICE in
dwarf2out.c for an Ada testcase built with optimization.
This crash happens during the late generation pass because
add_gnat_descriptive_type cannot find the type DIE corresponding to some
descriptive type after having tried to generate it. This is because the
DIE was generated during the early generation pass, but then pruned by
the type pruning machinery. So why was it pruned?
We are in a situation where we have cloned types (because of inlining,
IIUC) whose TYPE_NAME have non-null DECL_ABSTRACT_ORIGIN attributes. As
a consequence:
* In modified_type_die, the "handle C typedef types" part calls
gen_type_die on the cloned type.
* gen_type_die matches a typedef variant, and then calls gen_decl_die
on its TYPE_NAME, which will end up calling gen_typedef_die.
* gen_typedef_die checks decl_ultimate_origin for this TYPE_DECL, and
finds one, so it only adds a DW_AT_abstract_origin attribute to the
DW_TAG_typedef DIE, but the cloned type itself does not get its own
DIE.
* Back in modified_type_die, the call to lookup_type_die on the type
passed to gen_type_die returns NULL.
In the end, whole type trees, i.e. the ones referenced by
DECL_ABSTRACT_ORIGIN attributes, are never referenced from type pruning
"roots" and are thus pruned. The descriptive type at stake here is one
of them, hence the assertion failure.
This patch attemps to fix that with what seems to be the most sensible
thing to do in my opinion: updating the "handle C typedef types" part in
modified_type_die to check decl_ultimate_origin before calling
gen_type_die: if that function returns something not null, then we know
that gen_type_die/gen_typedef_die will not generate a DIE for the input
type, so we try to process the ultimate origin instead. It also updates
in a similar way gen_type_die_with_usage, assert that when
gen_typedef_die is called on nodes that have an ultimate origin, this
origin is themselves.
