f3d25c6570 PR preprocessor/53469 - argument tokens of _Pragma miss virtual location
Consider this short test snippet:

-------------------------8-------------------
    #define STRINGIFY(x) #x
    #define TEST(x) \
      _Pragma(STRINGIFY(GCC diagnostic ignored "-Wunused-local-typedefs")) \
      typedef int myint;

    void bar ()
    {
      TEST(myint)
    }
-------------------------8-------------------

The _Pragma is effectively ignored, and compiling with
-Wunused-local-typedefs warns on the local typedef, even though the
pragma should have prevented the warning to be emitted.

This is because when the preprocessor sees the _Pragma operator and
then goes to handle the first token ('GCC' here) that makes up its
operands, it retains the spelling location of that token, not its
virtual location.

Later when diagnostic_report_diagnostic is called to emit the warning
(or ignore it because of the pragma), it compares the location of the
first operand of the pragma with the location of the unused location,
(by calling linemap_location_before_p) and that comparison fails
because in this case, both locations should be virtual.

This patch fixes the issue by teaching the pragma handling to use
virtual locations.

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

libcpp/

	PR preprocessor/53469
	* directives.c (do_pragma): Use the virtual location for the
	pragma token, instead of its spelling location.

0823efedd0 backport: As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html...
Merge from cxx-conversion branch (http://gcc.gnu.org/wiki/cxx-conversion).

As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html, this patch
changes the default bootstrap process so that stage 1 always builds with a C++
compiler.

Other than the bootstrap change, the patch makes no functional changes to the
compiler.  Everything should build as it does now in trunk.  The main
changes in this patch are:

1- Configuration changes.
2- Re-write of VEC.
3- Re-write of gengtype to support C++ templates and
   user-provided marking functions.
4- New hash table class.
5- Re-write double_int.
6- Implement tree macros as inline functions so they can be
   called from gdb.

As discussed before, several of these changes do not fully change
the call sites to use the new APIs.

The bootstrap changes have already been tested on a wide range of
targets (http://gcc.gnu.org/wiki/CppBuildStatus).  Additionally,
I have tested the merged trunk on: x86_64-unknown-linux-gnu,
mips64el-unknown-linux-gnu, powerpc64-unknown-linux-gnu,
i686-pc-linux-gnu, and ia64-unknown-linux-gnu.

7ca643e17e PR preprocessor/53463 - Fix system header detection for built-in macro tokens
The location for a built-in macro token is BUILTIN_LOCATION.  When we
see that location value, we cannot know if that token was used in a
system header or not.  And that can trigger some unwanted warnings on
e.g, the use of __LONG_LONG_MAX__ built-in macro in system headers
when we compile with -pedantic, like in the test case accompanying
this patch.

In that case, I think we ought to step-up to see where the built-in
macro has been expanded, until we see a location that is not for a
built-in macro.  Then we can check if the resulting location is in a
system header or not.

Now that we step up to the location of first non-built-in-macro token,
it appeared that for
testsuite/c-c++-common/dfp/convert-int-saturate.c, G++ then fails to
emit the warning in:

    volatile unsigned int usi;
    int
    main ()
    {
      usi = DEC32_MAX;  /* { dg-warning "overflow in implicit constant conversion" } */
     ...
    }

Because DEC32_MAX is defined in the system header float.h as a
built-in macro:

    #define DEC32_MAX	__DEC32_MAX__

And during the parsing of the assignment expression that should have
led to the warning above, input_location is set to the location for
the DEC32_MAX, which is actually the location for the built-in
__DECL32_MAX_EXP.

A possible fix is to use the location of the "=" operator as the
default location for assignment expressions.  This is what the patch
does.

I had to adjust a couple of tests to arrange for this.

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

828a7f76c7 PR preprocessor/53229 - Fix diagnostics location when pasting tokens
As stated in the audit trail of this problem report, consider this
test case:

    $ cat test.c
	 1	struct x {
	 2	  int i;
	 3	};
	 4	struct x x;
	 5
	 6	#define TEST(X) x.##X
	 7
	 8	void foo (void)
	 9	{
	10	  TEST(i) = 0;
	11	}
    $

    $ cc1 -quiet test.c
    test.c: In function 'foo':
    test.c:10:1: error: pasting "." and "i" does not give a valid preprocessing token
       TEST(i) = 0;
     ^
    $

So, when pasting tokens, the error diagnostic uses the global and
imprecise input_location variable, leading to an imprecise output.

To properly fix this, I think libcpp should keep the token of the
pasting operator '##', instead of representing it with flag on the LHS
operand's token.  That way, it could use its location.  Doing that
would be quite intrusive though.  So this patch just uses the location
of the LHS of the pasting operator, for now.  It's IMHO better than
the current situation.

The patch makes paste_tokens take a location parameter that is used in
the diagnostics.  This change can still be useful later when we can
use the location of the pasting operator, because paste_tokens will
just be passed the new, more precise location.

Incidentally, it appeared that when getting tokens from within
preprocessor directives (like what is done in gcc.dg/cpp/paste12.c),
with -ftrack-macro-expansion disabled, the location of the expansion
point of macros was being lost because
cpp_reader::set_invocation_location wasn't being properly set.  It's
because when cpp_get_token_1 calls enter_macro_context, there is a
little period of time between the beginning of that later function and
when the macro is really pushed (and thus when the macro is really
expanded) where we wrongly consider that we are not expanding the
macro because macro_of_context is still NULL.  In that period of time,
in the occurrences of indirect recursive calls to cpp_get_token_1,
this later function wrongly sets cpp_reader::invocation_location
because cpp_reader::set_invocation_location is not being properly set.

To avoid that confusion the patch does away with
cpp_reader::set_invocation_location and introduces a new flag
cpp_reader::about_to_expand_macro_p that is set in the small time
interval exposed earlier.  A new in_macro_expansion_p is introduced as
well, so that cpp_get_token_1 can now accurately detect when we are in
the process of expanding a macro, and thus correctly collect the
location of the expansion point.

People seem to like screenshots.

Thus, after the patch, we now have:

    $ cc1 -quiet test.c
    test.c: In function 'foo':
    test.c:6:18: error: pasting "." and "i" does not give a valid preprocessing token
     #define TEST(X) x.##X
		      ^
    test.c:10:3: note: in expansion of macro 'TEST'
       TEST(i) = 0;
       ^
    $

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

0b2c4be5fd PR preprocessor/7263 - Avoid pedantic warnings on system headers macro tokens
Now that we track token locations accross macro expansions, it would
be cool to be able to fix PR preprocessor/7263 for real.  That is,
consider this example where we have a system header named header.h
like this:

	#define _Complex __complex__ #define _Complex_I 1.0iF

and then a normal C file like this:

    #include "header.h"

    static _Complex float c = _Complex_I;

If we compile the file with -pedantic, the usages of _Complex or
_Complex_I should not trigger any warning, even though __complex__ and
the complex literal are extensions to the standard C.

They shouldn't trigger any warning because _Complex and _Complex_I are
defined in a system header (and expanded in normal user code).

To be able to handle this, we must address two separate concerns.

First, warnings about non-standard usage of numerical literals are emitted
directly from within libcpp.  So we must teach libcpp's parser for numerical
literals to use virtual locations, instead of the spelling
location it uses today.  Once we have that, as the diagnostics machinery
already knows how to avoid emitting errors happening on tokens that come from
system headers, we win.

Second, there is the issue of tracking locations for declaration
specifiers, like the "_Complex" in the declaration:

	static _Complex float c;

For that, we need to arrange for each possible declaration specifier
to have its own location, because otherwise, we'd warn on e.g, on:

    _Complex float c;

but not on:

    static _Complex float c;

So this patch addresses the two concerns above.  It's actually a
follow-up on an earlier patch[1] I wrote as part of my initial work on
virtual locations.  We then agreed[2] that the second concern was
important to address before the patch could get a chance to go in.

3ad64f53da Properly initialize cpp_context in destringize_and_run
destringize_and_run forgets to initialize all the fields of the
cpp_context that it pushes.  Later _cpp_pop_context then gets confused
when it accesses context->tokens_kind via the call to macro_of_context
on context->prev.

The first hunk of this patch is the real obvious fix.  The second hunk
is just an assert that I am adding to err on the safe side.

Tested by on x86_64-unknown-linux-gnu against trunk by running the
test gcc.dg/gomp/macro-4.c under Valgrind, and bootstrapped.

c4ca1a0961 Strip "<built-in>" loc from displayed expansion context
Now that diagnostics for tokens coming from macro expansions point to
the spelling location of the relevant token (and then displays the
context of the expansion), some ugly (not so seldom) corner cases can
happen.

When the relevant token is a built-in token (which means the location
of that token is BUILTINS_LOCATION) the location prefix displayed to
the user in the diagnostic line is the "<built-in>:0:0" string.  For
instance:

    <built-in>:0:0: warning: conversion to 'float' alters 'int' constant value

For the user, I think this is surprising and useless.

A more user-friendly approach would be to refer to the first location
that (in the reported macro expansion context) is for a location in
real source code, like what is shown in the new test case
gcc/testsuite/g++.dg/warn/Wconversion-real-integer2.C accompanying
this patch.

To do this, I am making the line-map module provide a new
linemap_unwind_to_first_non_reserved_loc function that resolves a
virtual location to the first spelling location that is in real source
code.

I am then using that facility in the diagnostics printing module and
in the macro unwinder to avoid printing diagnostics lines that refer
to the locations for built-ins or more generally for reserved
locations.  Note that when I start the dance of skipping a built-in
location I also skip locations that are in system headers, because it
turned out that a lot of those built-ins are actually used in system
headers (e.g, "#define INT_MAX __INT_MAX__" where __INT_MAX__ is a
built-in).

Besides the user-friendliness gain, this patch allows a number of
regression tests to PASS unchanged with and without
-ftrack-macro-expansion.

Tested and bootstrapped on x86_64-unknown-linux-gnu against trunk.

Note that the bootstrap with -ftrack-macro-expansion exhibits other
separate issues that are addressed in subsequent patches.  This patch
just fixes one class of problems.

The patch does pass bootstrap with -ftrack-macro-expansion turned off,
though.

3600218c8b Fix expansion point loc for macro-like tokens
Consider the test case gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c.
Its interesting part is:

    #define A(x) vari x /* line 7.  */
    #define vari(x)
    #define B , varj
    int A(B) ;  /* line 10.  */

In its initial version, this test was being pre-processed as:

    # 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
    # 1 "build/gcc//"
    # 1 "<command-line>"
    # 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
    # 10 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
    int
    # 7 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
		 vari

	, varj ;

Note how "int" and "vari" are on separate lines, whereas "int" and
", varj" are on the same line.

This looks like a bug to me, even independantly from the macro
location tracking work.

With macro location tracking turned on, the preprocessed output
becomes:

    # 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
    # 1 "<command-line>"
    # 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
    # 10 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
    int vari , varj ;

Which, IMO, is what we'd expect.

This is due to an unexpected side effect of enter_macro_context when
passed a token that might look like a function-like macro at first
sight, but that it eventually considers to not be a macro after all.

This is the case for the "vari" token which looks like a macro when it
is first lexed, but is eventually considered to be a normal token by
enter_macro_context because it's not used as a function-like macro
invocation.

In that case, besides returning NULL, enter_macro_context sets
pfile->context->c.macro to NULL, making cpp_get_token_1 forget to set
the location of the "vari" to the expansion point of A.

enter_macro_context sets pfile->context->c.macro to NULL in that case
because funlike_invocation_p reads one token pass "foo", sees that
there is no '(' token, so we are not invoking the function-like
parameter.  It then puts the tokens (which it has read after "foo")
back into the tokens stream by calling _cpp_push_token_context on it,
which sets pfile->context->c.macro to NULL, saying in essence that the
current macro expansion context is "stopped".

The fix here is to teach _cpp_push_token and
push_extended_tokens_context to continue the current macro context
when passed a NULL macro.  But then, now that there can be several
continguous contexts associated with the same macro, we need to teach
_cpp_pop_context to re-enable the expansion of the current macro only
when we are really out of expanding the current macro.  Otherwise we
can run in cases where we have recursive expansions of the same macro.

Tested on x86_64-unknown-linux-gnu against trunk.  Now this test has
the same output with and without tracking locations accross macro
expansions.

separate issues that are addressed in subsequent patches.  This patch

7f5f5f98c5 Add new option, -Wliteral-suffix.
This option, which is enabled by default, causes the preprocessor to warn
when a string or character literal is followed by a ud-suffix which does
not begin with an underscore.  According to [lex.ext]p10, this is
ill-formed.

Also modifies the preprocessor to treat such ill-formed suffixes as separate
preprocessing tokens.  This is consistent with the Clang front end (see
http://llvm.org/viewvc/llvm-project?view=rev&revision=152287), and enables
backwards compatibility with code that uses formatting macros from
<inttypes.h>, as in the following code block:

b9bd6f7438 Reduce memory waste due to non-power-of-2 allocs
This patch basically arranges for the allocation size of line_map
buffers to be as close as possible to a power of two.  This
*significantly* decreases peak memory consumption as (macro) maps are
numerous and stay live during all the compilation.

The patch adds a new ggc_round_alloc_size interface to the ggc
allocator.  In each of the two main allocator implementations ('page'
and 'zone') the function has been extracted from the main allocation
function code and returns the actual size of the allocated memory
region, thus giving a chance to the caller to maximize the amount of
memory it actually uses from the allocated memory region.  In the
'none' allocator implementation (that uses xmalloc) the
ggc_round_alloc_size just returns the requested allocation size.

92582b753e Generate virtual locations for tokens
This second instalment uses the infrastructure of the previous patch
to allocate a macro map for each macro expansion and assign a virtual
location to each token resulting from the expansion.

To date when cpp_get_token comes across a token that happens to be a
macro, the macro expander kicks in, expands the macro, pushes the
resulting tokens onto a "token context" and returns a dummy padding
token. The next call to cpp_get_token goes look into the token context
for the next token [which is going to result from the previous macro
expansion] and returns it.  If the token is a macro, the macro expander
kicks in and you know the story.

This patch piggy-backs on that macro expansion process, so to speak.
First it modifies the macro expander to make it create a macro map for
each macro expansion. It then allocates a virtual location for each
resulting token.  Virtual locations of tokens resulting from macro
expansions are then stored on a special kind of context called an
"expanded tokens context".  In other words, in an expanded tokens
context, there are tokens resulting from macro expansion and their
associated virtual locations.  cpp_get_token_with_location is modified
to return the virtual location of tokens resulting from macro
expansion.  Note that once all tokens from an expanded token context have
been consumed and the context and is freed, the memory used to store the
virtual locations of the tokens held in that context is freed as well.
This helps reducing the overall peak memory consumption.

The client code that was getting macro expansion point location from
cpp_get_token_with_location now gets virtual location from it. Those
virtual locations can in turn be resolved into the different
interesting physical locations thanks to the linemap API exposed by
the previous patch.

Expensive progress. Possibly. So this whole virtual location
allocation business is switched off by default. So by default no
extended token is created. No extended token context is created
either. One has to use -ftrack-macro-expansion to switch this on. This
complicates the code but I believe it can be useful as some of our
friends found out at http://llvm.org/bugs/show_bug.cgi?id=5610

The patch tries to reduce the memory consumption by freeing some token
context memory that was being reused before. I didn't notice any
compilation slow down due to this immediate freeing on my GNU/Linux
system.

As no client code tries to resolve virtual locations to anything but
what was being done before, no new test case has been added.

46427374e1 Linemap infrastructure for virtual locations
This is the first instalment of a set which goal is to track locations
of tokens across macro expansions.  Tom Tromey did the original work
and attached the patch to PR preprocessor/7263.  This opus is a
derivative of that original work.

This patch modifies the linemap module of libcpp to add virtual
locations support.

A virtual location is a mapped location that can resolve to several
different physical locations.  It can always resolve to the spelling
location of a token.  For tokens resulting from macro expansion it can
resolve to:
  - either the location of the expansion point of the macro.
  - or the location of the token in the definition of the
  macro
  - or, if the token is an argument of a function-like macro,
  the location of the use of the matching macro parameter in
  the definition of the macro

The patch creates a new type of line map called a macro map.  For every
single macro expansion, there is a macro map that generates a virtual
location for every single resulting token of the expansion.

The good old type of line map we all know is now called an ordinary
map.  That one still encodes spelling locations as it has always had.

As a result linemap_lookup as been extended to return a macro map when
given a virtual location resulting from a macro expansion.  The layout
of structs line_map has changed to support this new type of map.  So
did the layout of struct line_maps.  Accessor macros have been
introduced to avoid messing with the implementation details of these
datastructures directly.  This helped already as we have been testing
different ways of arranging these datastructure.  Having to constantly
adjust client code that is too tied with the internals of line_map and
line_maps would have been even more painful.

Of course, many new public functions have been added to the linemap
module to handle the resolution of virtual locations.

This patch introduces the infrastructure but no part of the compiler
uses virtual locations yet.

However the client code of the linemap data structures has been
adjusted as per the changes.  E.g, it's not anymore reliable for a
client code to manipulate struct line_map directly if it just wants to
deal with spelling locations, because struct line_map can now
represent a macro map as well.  In that case, it's better to use the
convenient API to resolve the initial (possibly virtual) location to a
spelling location (or to an ordinary map) and use that.

This is the reason why the patch adjusts the Java, Ada and Fortran
front ends.

Also, note that virtual locations are not supposed to be ordered for
relations '<' and '>' anymore.  To test if a virtual location appears
"before" another one, one has to use a new operator exposed by the
line map interface.  The patch updates the only spot (in the
diagnostics module) I have found that was making the assumption that
locations were ordered for these relations.  This is the only change
that introduces a use of the new line map API in this patch, so I am
adding a regression test for it only.

046957830e remove useless if-before-free tests
Change "if (E) free (E);" to "free (E);" everywhere except in the
libgo/, intl/, zlib/ and classpath/ directories.
Also transform equivalent variants like
"if (E != NULL) free (E);" and allow an extra cast on the
argument to free.  Otherwise, the tested and freed "E"
expressions must be identical, modulo white space.
