course, it doesn't hurt to say all gprs need to be saved for eh_return

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.

compiler: fix buglet in lshift type determination

    It's possible to construct an lshift expression using unsafe.Sizeof
    that is technically a compile-time constant but can't be evaluated
    without going through backend methods. In this case, insure that
    Type::make_non_abstract_type is called on the numeric operand of the
    shift (as opposed to leaving as abstract), to avoid an assert later on
    in the compiler flow.

rs6000: Use SAVE_MULTIPLE only if we restore what it saves (PR80938)

We can have SAVE_MULTIPLE while we do not have REST_MULTIPLE.  If the
inline restore does not restore all registers, the CFI for the save
and restore can conflict if things are shrink-wrapped.

We could restore all registers that are saved (not ideal), or emit
the CFI notes to say we did (which will work fine, but is also not
so great); instead, let's not save the registers that are unused.

compiler: handle >32bit exponent in Ldexp

    Libgo's implementation of math.Ldexp declared the libc "ldexp" as
    taking an 'int' exponent argument, which is not quite right for 64-bit
    platforms (exp arg is always int32); this could yield incorrect
    results for exponent values outside the range of Minint32/Maxint32.
    Fix by upating the type for the libc version of ldexp, and adding
    guards to screen for out-of-range exponents.
