When a built-in macro is expanded, the location of the token in the
epansion list is the location of the expansion point of the built-in
macro.
This patch creates a virtual location for that token instead,
effectively tracking locations of tokens resulting from built-in macro
tokens.

In this problem report, the compiler is fed a (bogus) translation unit
in which some literals contain bytes whose value is zero. The
preprocessor detects that and proceeds to emit diagnostics for that
king of bogus literals. But then when the diagnostics machinery
re-reads the input file again to display the bogus literals with a
caret, it attempts to calculate the length of each of the lines it got
using fgets. The line length calculation is done using strlen. But
that doesn't work well when the content of the line can have several
zero bytes. The result is that the read_line never sees the end of
the line because strlen repeatedly reports that the line ends before
the end-of-line character; so read_line thinks its buffer for reading
the line is too small; it thus increases the buffer, leading to a huge
memory consumption and disaster.
Here is what this patch does.
location_get_source_line is modified to return the length of a source
line that can now contain bytes with zero value.
diagnostic_show_locus() is then modified to consider that a line can
have characters of value zero, and so just shows a white space when
instructed to display one of these characters.
Additionally location_get_source_line is modified to avoid re-reading
each and every line from the beginning of the file until it reaches
the line number N that it is instructed to get; this was leading to
annoying quadratic behaviour when reading adjacent lines near the end
of (big) files. So a cache is now associated to the file opened in
text mode. When the content of the file is read, that content is
stashed in the file cache. That file cache is searched for line
delimiters. A number of line positions are saved in the cache and a
number of file caches are kept in memory. That way when
location_get_source_line is asked to read line N + 1, it just has to
start reading from line N that it has already read.

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.

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.

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.

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.
