C++: show location of unclosed extern "C" specifications
If the user fails to close an extern "C" linkage specifier, and then
uses templates, they will run into "template with C linkage" errors.
From personal experience, it can be hard to tell where the
extern "C" began. As of r251026 there will be a message highlighting
the unclosed '{', but this may be hard to spot at the very end of
the errors.
This patch adds a note to the various diagnostics that complain
about C linkage, showing the user where the extern "C" specification
began.
gcc/cp/ChangeLog:
* cp-tree.h (maybe_show_extern_c_location): New decl.
* decl.c (grokfndecl): When complaining about literal operators
with C linkage, issue a note giving the location of the
extern "C".
* parser.c (cp_parser_new): Initialize new field
"innermost_linkage_specification_location".
(cp_parser_linkage_specification): Store the location
of the linkage specification within the cp_parser.
(cp_parser_explicit_specialization): When complaining about
template specializations with C linkage, issue a note giving the

C/C++: add fix-it hints for various missing symbols
The patch improves our C/C++ frontends' handling of missing
symbols, by making c_parser_require and cp_parser_require use
"better" locations for the diagnostic, and insert fix-it hints,
under certain circumstances (see the comments in the patch for
full details).
For example, for this code with a missing semicolon:
$ cat test.c
int missing_semicolon (void)
{
return 42
}
trunk currently emits:
test.c:4:1: error: expected ';' before '}' token
}
^
This patch adds a fix-it hint for the missing semicolon, and puts
the error at the location of the missing semicolon, printing the
followup token as a secondary location:
test.c:3:12: error: expected ';' before '}' token
return 42
^
;
}
~
More examples can be seen in the test cases.

C++: avoid partial duplicate implementation of cp_parser_error
In r251026 (aka
3fe34694f0990d1d649711ede0326497f8a849dc,
"C/C++: show pertinent open token when missing a close token")
I copied part of cp_parser_error into cp_parser_required_error,
leading to duplication of code.
This patch eliminates this duplication by merging the two copies of the
code into a new cp_parser_error_1 subroutine.
Doing so removes an indentation level, making the patch appear to have
more churn than it really does.
The patch also undoes the change to g++.dg/parse/pragma2.C, as the
old behavior is restored.

Enable ifunc attribute by default for ARM GNU/Linux
Similar to other architectures with IFUNC binutils/glibc support, this
patch enables the ifunc attribute for ARM GNU/Linux. Although not
required for build master GLIBC, the intention is to allow refactor
its assembly implementation to C.
Tested compilation of glibc (in conjunction with a glibc patch to
support using the attribute on ARM) with build-many-glibcs.py (with
a patch to add a armv7 variant which enables multiarch). I have

rs6000: insn_cost
This adds an implementation of the insn_cost hook to rs6000.
This implementations is very minimal (so far). It is mostly based on
how many machine instructions are generated by an RTL insn, and it also
looks at the instruction type. Floating point insns are costed as if
all machine instructions it generates are floating point; the other
insns are treated as if all but one are integer insns (and one is the
specified type). Load instructions are treated as costing twice as
much, and load locked and sync insns as three times as much (just like
the original costs), and integer div and mul are handled as well.
Each define_insn (etc.) can set a "cost" attribute to override this
general cost. With optimization for size, the cost is set equal to the
value of the "length" attribute.
With this, the majority of cost differences between old and new are
where the old was wrong. Also, benchmarks show a slight win (if
anything). Some refinements are obviously needed.
