This patch fixes a bug in the bswap pass.

This patch fixes a bug in the bswap pass. In big-endian BIT_FIELD_REF uses
big-endian bit numbering so we need to adjust the bit position.
The existing version could potentially generate incorrect code however GCC
doesn't emit a BIT_FIELD_REF to access the low byte in a register, so the
symbolic number never matches in big-endian.

rs6000: Fix split of ashdi3_extswsli_dot for memory (PR71670)

The splitter for ashdi3_extswsli_dot for cr0 with memory uses emit_insn
gen_ashdi3_extswsli_dot, which does not work because that emits a scratch,
while the splitter runs after reload so there should be a real register
instead. We can laboriously fix that up, or emit using
gen_ashdi3_extswsli_dot2 instead. This patch does the latter.

Call tls_get_addr via GOT for GNU TLS if possible

There are extensions to x86-64 psABI:

https://groups.google.com/forum/#!topic/x86-64-abi/de5_KnLHxtI

and i386 psABI:

https://groups.google.com/forum/#!topic/ia32-abi/awsRSvJOJfs

to call tls_get_addr via GOT.  X86 assembler and linker in binutils 2.27
implemented

call *__tls_get_addr@GOTPCREL(%rip)

in 64-bit and

call *___tls_get_addr@GOT(%reg)

in 32-bit to access global and local thread loal variables in shared
library.  We check if 32-bit x86 assembler and linker work with

call *___tls_get_addr@GOT(%reg)

as 32-bit and 64-bit assembler and linker are enabled togther.

In 32-bit, since any integer register except EAX, which is used to pass
parameter to ___tls_get_addr, and ESP, can be used as GOT base, a new
register class, TLS_GOTBASE_REGS, along with a new constraint, Yb, are
added.  They are used to improve register allocation for 32-bit dynamic
TLS patterns.

Add make autoprofiledbootstrap

Add support for profiledbootstrap with autofdo. Will be useful
to get better testing coverage of autofdo.

This requires Linux perf and autofdo to be installed, only
really for x86_64 linux on Intel so far.

Profile the whole build process with perf, then convert the file,
and pass it back to the compiler in the feedback stage.

The conversion has to be done per language, as only that knows
the name of the binary. Currently we only do it for C and C++,
as the other languages don't have enough coverage during a normal
bootstrap.

For lto1 it is also disabled, because it would only be useful during a LTO
bootstrap, but right now autofdo and LTO are not working together due to
PR66229

For common backend files always the profile output of the C++ compiler
is used. In theory multiple inputs could be merged here, but so far
that is not implemented.

The method is not friendly to partial rebuilds, as only the profile
information from the current rebuild is used. So if an error
occurs it is best to clean and restart, otherwise the code
quality may be worse.

This patch is fairly large, but most of it is auto generated from
autogen in Makefile.in. for the new stage targets.

Passes profiledbootstrap and normal bootstrap on x86_64-linux.
autoprofiledbootstrap is currently not working due to
PR70427 (but it finishes with that worked around)

The autofdo'ed compiler is ~7% faster on insn-recog.i (vs ~11% for
profiledfeedback), and ~4% faster for tramp3d-v4 (vs 10% for
profiledfeedback) on a Sandy Bridge system.

Run profile feedback tests with autofdo

Extend the existing bprob and tree-prof tests to also run with autofdo.
The test runtimes are really a bit too short for autofdo, but it's
a reasonable sanity check.

This only works natively for now.

dejagnu doesn't seem to support a wrapper for unix tests, so I had
to open code running these tests. That should be ok due to the
native run restrictions.

Add gcc-auto-profile script

Using autofdo is currently something difficult. It requires using the
model specific branches taken event, which differs on different CPUs.
The example shown in the manual requires a special patched version of
perf that is non standard, and also will likely not work everywhere.

This patch adds a new gcc-auto-profile script that figures out the
correct event and runs perf.

This is needed to actually make use of autofdo in a generic way
in the build system and in the test suite.

Since maintaining the script would be somewhat tedious (needs changes
every time a new CPU comes out) I auto generated it from the online
Intel event database. The script to do that is in contrib and can be
rerun.

Right now there is no test if perf works in configure. This
would vary depending on the build and target system, and since
it currently doesn't work in virtualization and needs uptodate
kernel it may often fail in common distribution build setups.

So far the script is not installed.

reformatting.

* sem_util.ads (Address_Value): Declare new function.
* sem_util.adb (Address_Value): New function extracted
unmodified from Apply_Address_Clause_Check, which returns the
underlying value of the expression of an address clause.
* checks.adb (Compile_Time_Bad_Alignment): Delete.
(Apply_Address_Clause_Check): Call Address_Value on
the expression.  Do not issue the main warning here and
issue the secondary warning only when the value of the
expression is not known at compile time.
* sem_ch13.adb (Address_Clause_Check_Record): Add A component and
adjust the description.
(Analyze_Attribute_Definition_Clause): In the case
of an address, move up the code creating an entry in the table of
address clauses.  Also create an entry for an absolute address.
(Validate_Address_Clauses): Issue the warning for absolute
addresses here too.  Tweak condition associated with overlays
for consistency.

* sem_ch13.adb (Is_Predicate_Static): An inherited predicate
can be static only if it applies to a scalar type.

2016-06-22  Ed Schonberg  <schonberg@adacore.com>

* exp_util.adb (Adjust_Result_Type): Convert operand to base
type to prevent spurious constraint checks on subtypes of Boolean.

* debug.adb: Document debug switch -gnatd.o.
* sem_elab.adb (Check_Internal_Call): Debug switch -gnatd.o
now causes a more conservative treatment of indirect calls,
treating P'Access as a call to P in more cases. We Can't make
this the default, because it breaks common idioms, for example
the soft links.
* sem_util.adb: Add an Assert.

2016-06-22  Bob Duff  <duff@adacore.com>

* a-cuprqu.ads, a-cuprqu.adb: Completely rewrite this package. Use
red-black trees, which gives O(lg N) worst-case performance on
Enqueue and Dequeue. The previous version had O(N) Enqueue in
the worst case.

2016-06-22  Arnaud Charlet  <charlet@adacore.com>

* sem_warn.adb: minor style fix in comment.
* spark_xrefs.ads (Scope_Num): type refined to positive integers.
* lib-xref-spark_specific.adb (Detect_And_Add_SPARK_Scope):
moved into scope of Collect_SPARK_Xrefs.
(Add_SPARK_Scope): moved into scope of Collect_SPARK_Xrefs;
now uses Dspec and Scope_Id from Collect_SPARK_Xrefs.
(Collect_SPARK_Xrefs): refactored to avoid retraversing the list
of scopes.
* sem_ch3.adb (Build_Discriminal): Set Parent of the discriminal.

* exp_ch7.adb (Add_Invariant): Replace the
current type instance with the _object parameter even in ASIS mode.
(Build_Invariant_Procedure_Body): Do not insert the
invariant procedure body into the tree for ASIS and GNATprove.
(Build_Invariant_Procedure_Declaration): Do not insert the
invariant procedure declaration into the tree for ASIS and
GNATprove.
* lib-xref-spark_specific.adb (Add_SPARK_Scope): Update comment.

* sem_ch6.adb (Set_Actual_Subtypes): If the type of the actual
has predicates, the actual subtype must be frozen properly
because of the generated tests that may follow.  The predicate
may be specified by an explicit aspect, or may be inherited in
a derivation.

2016-06-22 Ed Schonberg <schonberg@adacore.com>

* exp_ch4.adb (In_Range_Chec)): New predicate, subsidiary of
Expand_N_In: within an expanded range check that might raise
Constraint_Error do not generate a predicate check as well. It
is redundant because the context will add an explicit predicate
check, and it will raise the wrong exception if it fails.
* lib-xref-spark_specific.adb (Add_SPARK_File): Remove useless checks
since dependency units always have an associated compilation unit.
