dg-cmp-results: display NA->FAIL & NA->UNRESOLVED by default

Currently, dg-cmp-results will not print anything for a test that was
not run before, even if it is a FAIL or UNRESOLVED now. This means that
when contributing a code change together with a testcase in the same
commit one must run dg-cmp-results twice: once to check for regression
on a full testsuite run and once against the new testcase with -v -v.
This also prevents using dg-cmp-results on sum files generated with
test_summary since these would not contain PASS.

This patch changes dg-cmp-results to print NA->FAIL and NA->UNRESOLVED
changes by default.

[testsuite] Fix sibcall-9 & sibcall-10 with -fPIC

gcc.dg/sibcall-9.c and gcc.dg/sibcall-10.c give execution failure
on ARM when compiled with -fPIC due to the PIC access to volatile
variable v creating an extra spill which causes the frame size of the
two recursive functions to be different. Making the variable static
solve the issue because the variable can be access in a PC-relative way
and avoid the spill, while still testing sibling call as originally
intended.

gOlogy: do not change code in isolate-paths for warnings only

The isolate-paths pass is activated by various -f flags, but also by
-Wnull-dereference.  Most of its codegen changes are conditioned on at
least one of the -f flags, but those that detect, warn about and
isolate paths that return the address of local variables are enabled
even if the pass is activated only by -Wnull-dereference.

-W flags should not cause codegen changes, so this patch makes the
codegen changes conditional on the presence of any of the -f flags
that activate the pass.  Should we have a separate option to activate

[arm]  Update default CPUs during configure

There are a couple of places in config.gcc where the default CPU is
still arm6, but that was removed as a supported CPU earlier this year.
This patch fixes those entries.

The default CPU for configurations that do not explicitly set a
default is now arm7tdmi (so assumes thumb is available).  Given that
StrongArm is on the deprecated list, this is a better default than we
had previously.

For NetBSD the default is StrongArm; this is the only remaining port
that uses the old ABI and really still carries support for non-thumb
based targets.

combine: Do not combine moves from hard registers

On most targets every function starts with moves from the parameter
passing (hard) registers into pseudos.  Similarly, after every call
there is a move from the return register into a pseudo.  These moves
usually combine with later instructions (leaving pretty much the same
instruction, just with a hard reg instead of a pseudo).

This isn't a good idea.  Register allocation can get rid of unnecessary
moves just fine, and moving the parameter passing registers into many
later instructions tends to prevent good register allocation.  This
patch disallows combining moves from a hard (non-fixed) register.

This also avoid the problem mentioned in PR87600 #c3 (combining hard
registers into inline assembler is problematic).

Because the register move can often be combined with other instructions
*itself*, for example for setting some condition code, this patch adds
extra copies via new pseudos after every copy-from-hard-reg.

On some targets this reduces average code size.  On others it increases
it a bit, 0.1% or 0.2% or so.  (I tested this on all *-linux targets).

Don't double-count early-clobber matches.

Given a pattern with a number of operands:

(match_operand 0 "" "=&v")
(match_operand 1 "" " v0")
(match_operand 2 "" " v0")
(match_operand 3 "" " v0")

GCC will currently increment "reject" once, for operand 0, and then decrement
it once for each of the other operands, ending with reject == -2 and an
assertion failure.  If there's a conflict then it might try to decrement reject
yet again.

Incidentally, what these patterns are trying to achieve is an allocation in
which operand 0 may match one of the other operands, but may not partially
overlap any of them.  Ideally there'd be a better way to do this.

In any case, it will affect any pattern in which multiple operands may (or
must) match an early-clobber operand.

The patch only allows a reject-- when one has not already occurred, for that
operand.

parameter to predicates stmt_could_throw_p, stmt_can_throw_external
and stmt_can_throw_internal.

My motivation was ability to use stmt_can_throw_external in IPA
analysis phase without the need to push cfun.  As I have discovered,
we were already doing that in cgraph.c, which this patch avoids as
well.  In the process, I had to add a struct function parameter to
stmt_could_throw_p and decided to also change the interface of
stmt_can_throw_internal just for the sake of some minimal consistency.

In the process I have discovered that calling method
cgraph_node::create_version_clone_with_body (used by ipa-split,
ipa-sra, OMP simd and multiple_target) leads to calls of
stmt_can_throw_external with NULL cfun.  I have worked around this by
making stmt_can_throw_external and stmt_could_throw_p gracefully
accept NULL and just be pessimistic in that case.  The problem with
fixing this in a better way is that struct function for the clone is
created after cloning edges where we attempt to push the yet not
existing cfun, and moving it before would require a bit of surgery in
tree-inline.c.  A slightly hackish but simpler fix might be to
explicitely pass the "old" function to symbol_table::create_edge
because it should be just as good at that moment.  In any event, that
is a topic for another patch.

I believe that currently we incorrectly use cfun in
maybe_clean_eh_stmt_fn and maybe_duplicate_eh_stmt_fn, both in
tree-eh.c, and so I have fixed these cases too.  The bulk of other
changes is just mechanical adding of cfun to all users.

Bootstrapped and tested on x86_64-linux (also with extra NULLing and
restoring cfun to double check it is not used in a place I missed), OK
for trunk?

Thanks,

Martin

S/390: Make "b" constraint match literal pool references

Improves the code generation by getting rid of redundant LAs, as seen
in the following example:

- la %r1,0(%r13)
- lg %r4,0(%r1)
+ lg %r4,0(%r13)

Also allows to proceed with the merge of movdi_64 and movdi_larl.
Currently LRA decides to spill literal pool references back to the
literal pool, because it preliminarily chooses alternatives with
CT_MEMORY constraints without calling
satisfies_memory_constraint_p (). Later on it notices that the
constraint is wrong and fixes it by spilling.  The constraint in this
case is "b", and the operand is a literal pool reference.  There is
no reason to reject them.  The current behavior was introduced,
apparently unintentionally, by
https://gcc.gnu.org/ml/gcc-patches/2010-09/msg00812.html

The patch affects a little bit more than mentioned in the subject,
because it changes s390_loadrelative_operand_p (), which is called not
only for checking the "b" constraint.  However, the only caller for
which it should really not accept literal pool references is
s390_check_qrst_address (), so it was changed to explicitly do so.

i386: Enable AVX512 memory broadcast for FNMADD

Many AVX512 vector operations can broadcast from a scalar memory source.
This patch enables memory broadcast for FNMADD operations.  In order to
support AVX512 memory broadcast for FNMADD, FNMADD builtin functions are
also added, instead of passing the negated value to FMA builtin functions.

Fix tests that use allocators with incorrect value types

As a GNU extension we allow containers to be instantiated with
allocators that use a different value type from the container, and
automatically rebind the allocator to the correct type. This extension
is disabled in strict modes (when __STRICT_ANSI__ is defined, i.e.
-std=c++NN dialects). These testcases unintentionally rely on the

Remove duplicate tests

These tests originally existed to check the containers in C++11 mode,
when the default was C++98 mode. Now that the default is C++14 (and we

compiler: don't export any functions with special names

    This keeps init functions from appearing in the export data.  Checking
    for special names in general means that we don't need to check
    specifically for nested functions or thunks, which have special names.

rs6000: Put CR0 first in REG_ALLOC_ORDER

IRA and LRA prefer to use CR7 (which is first in REG_ALLOC_ORDER) over
CR0, although the latter often is cheaper ("x" vs. "y" constraints).
We should figure out why this is and fix it; but until that is done,
this patch makes CR0 the first allocated register: it improves the
current code, and it is required for later patches to be effective.

(It changes two testcases to no longer look at what CR field is
allocated).

* config/rs6000/rs6000.h (REG_ALLOC_ORDER): Move 68 (that is, CR0) to
be the first CR field allocated.

* gcc.target/powerpc/safe-indirect-jump-2.c: Do not check assigned CR
field number.
