Hi Uros:
This patch fix Zhaoxin CPU vendor ID detection problem and add zhaoxin
"lujiazui" processor support.
Currently gcc can't recognize Zhaoxin CPU(vendor ID "CentaurHauls" and
"Shanghai") if user use -march=native option, which is confusing for users.

The problem is that the resolution of expanded names implicitly assumes
that the visible and private homonyms in a given scope are segregated on
the homonym chain, and this was no longer the case for equality operators
in the specific case at stake.

When expanding attribute Loop_Entry we create constant object
declarations and put them just before the loop. The current values of
variables at the point of Loop_Entry attribute must not be used when
analysing the initialization expressions of these constants, because
they might be different from
The current value propagation applies only to assignable objects and
doesn't make sense for subprogram entities. This was a mistake
introduced when extending the current value propagation years ago.
Cleanup related to fixing interference between expansion of attribute
Loop_Entry and current value
This patch corrects an error in the compiler whereby a function
requiring the generation of a postconditions procedure may cause an
uninitialized memory read when the return type
Has_Unconstrained_Elements or is an unconstrained array.
The error occurs because evaluation of postconditions happens
An object declaration (other than a deferred constant declaration)
causes freezing where it occurs (13.14(6)), which means every name
occurring within it causes freezing (13.14(4/1)), and when the name in a
subtype_mark causes freezing, the denoted subtype is frozen (13.14(11)).
Hence, one needs to
Proof of an assertion is not automatic anymore. Add two assertions
before it to guide the prover.

Setting this parameter to zero when calling the Configure procedure has
the effect of disabling completely the tracking of the biggest memory
users, which wasn't clear from the current documentation. So this patch
enhances the documentation of both the Configure procedure as well as
the Dump proce
The QNX version of __gnat_install_handler calls sigaction for a number
of signals, and then prints an error message when the the call failed.
But unfortunately, except for the first call, we forgot to store
sigaction's return value, so the check that ensues uses a potentially
uninitialized variable
On QNX, the sigaction handler is incorrectly installed via the
sa_handler field of struct sigaction, rather than the sa_sigaction
field. This triggers a compilation warning due to a mismatch between the
function's signature and the field's type.

bzero is marked as legacy in POSIX.1-2001, and using it triggers a
deprecation warnings on some systems such as QNX. This change adjusts
the one place where we use it in terminals.c to use memset instead.
This, in turns, allows us to get rid of a hack for HP/UX and Solaris.

Fix the escaping of the loop variable from the loop scope in both forms
of iterated element associations (i.e. "for J in ..." and "for J of
..."). Create a dedicated scope around the analyses of both loops. Also
create a copy of the Loop_Parameter_Specification instead of analyzing
(and modifying)
The front-end drops the declaration of a temporary on the floor because
Insert_Actions fails to climb up out of an N_Iterated_Component_Association
when the temporary is created during the analysis of its Discrete_Choices.

The semantic analysis of predicates involves a fair amount of tree
copying because of both semantic and implementation considerations, and
there is a difficulty with quantified expressions since they declare a
new entity that cannot be shared between the various copies of the tree.
