Consider the example code mentionned in this PR:
$ cat -n test.c
1 #define C(a, b) a ## b
2 #define L(x) C(L, x)
3 #define M(a) goto L(__LINE__); __LINE__; L(__LINE__):
4 M(a /* --> this is the line of the expansion point of M. */
5 ); /* --> this is the line of the end of the invocation of M. */
$
"cc1 -quiet -E test.c" yields:
goto L5; 5; L4:
;
Notice how we have a 'L4' there, where it should be L5. That is the issue.
My understanding is that during the *second* expansion of __LINE__
(the one between the two L(__LINE__)), builtin_macro() is called by
enter_macro_context() with the location of the expansion point of M
(which is at line 4). Then _cpp_builtin_macro_text() expands __LINE__
into the line number of the location of the last token that has been
lexed, which is the location of the closing parenthesis of the
invocation of M, at line 5. So that invocation of __LINE__ is
expanded into 5.
Now let's see why the last invocation of __LINE__ is expanded into 4.
In builtin_macro(), we have this code at some point:
/* Set pfile->cur_token as required by _cpp_lex_direct. */
pfile->cur_token = _cpp_temp_token (pfile);
cpp_token *token = _cpp_lex_direct (pfile);
/* We should point to the expansion point of the builtin macro. */
token->src_loc = loc;
The first two statements insert a new token in the stream of lexed
token and pfile->cur_token[-1], is the "new" last token that has been
lexed. But the location of pfile->cur_token[-1] is the same location
as the location of the "previous" pfile->cur_token[-1], by courtesy of
_cpp_temp_token(). So normally, in subsequent invocations of
builtin_macro(), the location of pfile->cur_token[-1] should always be
the location of the closing parenthesis of the invocation of M at line
5. Except that that code in master now has the statement
"token->src_loc = loc;" on the next line. That statement actually
sets the location of pfile->cur_token[-1] to 'loc'. Which is the
location of the expansion point of M, which is on line 4.
So in the subsequent call to builtin_macro() (for the last expansion
of __LINE__ in L(__LINE__)), for _cpp_builtin_macro_text(),
pfile->cur_token[-1].src_loc is going to have a line number of 4.
I think the core issue here is that the location that is passed to
builtin_macro() from enter_macro_context() is not correct when we are
in presence of a top-most function-like macro invocation; in that
case, that location should be the location of the closing parenthesis
of the macro invocation. Otherwise, if we are in presence of a a
top-most object-like macro invocation then the location passed down
to builtin_macro should be the location of the expansion point of the
macro.
That way, in the particular case of the input code above, the location
received by builtin_macro() will always have line number 5.
Boostrapped and tested on x86_64-unknown-linux-gnu against trunk.

This patch makes cpplib track the original spellings of extended
identifiers, as well as the canonical UTF-8 version, in order to
follow standard semantics properly without needing a convoluted and
undocumented canonicalization in translation phase 1 (see bug 9449
comments 39-46 regarding such a canonicalization).
The spelling is tracked in cpp_identifier and cpp_macro_arg without
making cpp_token any larger. The original spelling is used for checks
of duplicate macro definitions, stringizing (see the C++ tests added;
this case is only an issue for C++ not C because C makes it
implementation-defined whether a \ is inserted before the \ of a UCN
in a string or character constant when stringizing, while C++ does
not), pasting (relevant when the result is then stringized for C++)
and when macro definitions are output as text (e.g. for -d options).
Once a macro has been defined, only the original spelling of the
argument names needs keeping in the argument list. While it is being
defined, however, both spellings are needed: the original one for
subsequent saving for checks of duplicate macro definitions, and the
canonical one which is the node marked specially to generate macro
argument tokens rather than normal identifier tokens. The buffer that
is used to save the original values of the identifier tokens is
changed so that it stores both those original values and a pointer to
the canonical hash nodes, so that those canonical nodes can be found
when their values need restoring after the macro definition has been
parsed.
I believe this covers the known standards issues in extended
identifiers support (the remaining unimplemented C99 areas in GCC all
being floating-point-related), except for C++ translation of extended
characters to UCNs in phase 1 (which I have no plans to work on).
There are however probably issues left with handling of extended
identifiers in other places, as listed in
<https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00337.html> (those
issues are generally the sort of thing that could be addressed as bugs
outside development stage 1). (The bulk of the potential issues Zack
was concerned about in 2003-5, that resulted in extended identifiers
being disabled in the absence of -fextended-identifiers, were
effectively eliminated by the audit and fixes I did in 2009, however;
that todo list reflects what was left over after that audit.)

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.

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;
^
$

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.

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.
