Fix ICE for missing header fix-it hints with overlarge #line directives (PR c/84852) · 082284da

PR c/84852 reports an ICE inside diagnostic_show_locus when printing
a diagnostic for a source file with a #line >= 2^31:

  #line 7777777777
  int foo (void) { return strlen(""); }

where we're attempting to print a fix-it hint at the top of the file
and underline the "strlen" (two "line spans").

The
  #line 7777777777
won't fix within the 32-bit linenum_type, and is truncated from
  0x1cf977871
to
   0xcf977871
i.e. 3482810481 in decimal.

Such a #line is reported by -pedantic and -pedantic-errors, but we
shouldn't ICE.

The ICE is an assertion failure within layout::calculate_line_spans,
where the line spans have not been properly sorted.

The layout_ranges are stored as int, rather than linenum_type,
giving line -812156815 for the error, and line 1 for the fix-it hint.

However, line_span uses linenum_type rather than int.

line_span::comparator compares these values as int, and hence
decides that (linenum_type)3482810481 aka (int)-812156815 is less
than line 1.

This leads to this assertion failing in layout::calculate_line_spans:

1105	      gcc_assert (next->m_first_line >= current->m_first_line);

since it isn't the case that 1 >= 3482810481.

The underlying problem is the mix of types for storing line numbers:
in parts of libcpp and diagnostic-show-locus.c we use linenum_type;
in other places (including libcpp's expanded_location) we use int.

I looked at using linenum_type throughout, but doing so turned into
a large patch, so this patch fixes the ICE in a less invasive way
by merely using linenum_type more consistently just within
diagnostic-show-locus.c, and fixing line_span::comparator to properly
handle line numbers (and line number differences) >= 2^31, by using
a new helper function for linenum_type differences, computing the
difference using long long, and using the sign of the difference
(as the difference might not fit in the "int" return type imposed
by qsort).

	from int to linenum_type.

Add ability to remap file names in __FILE__, etc (PR other/70268) · 7365279f

This commit adds the -fmacro-prefix-map option that allows remapping of file
names in __FILE__, __BASE_FILE__, and __builtin_FILE(), similar to how
-fdebug-prefix-map allows to do the same for debug information.

Additionally, it adds -ffile-prefix-map which can be used to specify both
mappings with a single option (and, should we need to add more -f*-prefix-map
options in the future, those as well).

Reject fix-it hints for various awkward boundary cases (PR c/82050) · 6df8934f

PR c/82050 reports a failed assertion deep within diagnostic_show_locus's
code for printing fix-it hints.

The root cause is a fix-it hint suggesting a textual replacement,
where the affected column numbers straddle the LINE_MAP_MAX_COLUMN_NUMBER
boundary, so that the start of the range has a column number, but the
end of the range doesn't.

The fix is to verify that the column numbers are sane when adding fix-it
hints to a rich_location, rejecting fix-it hints where they are not.

C++: provide macro used-before-defined hint (PR c++/72786) · 01ada121

This patch uses the name_hint/deferred_diagnostic to provide
a message in the C++ frontend if a macro is used before it is defined
e.g.:

test.c:6:24: error: expected ';' at end of member declaration
   virtual void clone() const OVERRIDE { }
                        ^~~~~
                             ;
test.c:6:30: error: 'OVERRIDE' does not name a type
   virtual void clone() const OVERRIDE { }
                              ^~~~~~~~
test.c:6:30: note: the macro 'OVERRIDE' had not yet been defined
test.c:15:0: note: it was later defined here
 #define OVERRIDE override

It's possible to do it from the C++ frontend as tokenization happens
up-front (and hence the macro already exists when the above is parsed);
I attempted to do it from the C frontend, but because the C frontend only
tokenizes on-demand during parsing, the macro isn't known about until
later.

diagnostics: get rid of *_at_rich_loc in favor of overloading · 64a5912c

Adding a fix-it hint currently involves changing e.g.:

  error_at (token->location,
            "unknown type name %qE; did you mean %qs?",
            token->value, hint);
to:

  gcc_rich_location richloc (token->location);
  richloc.add_fixit_replace (hint);
  error_at_rich_loc (&richloc,
                     "unknown type name %qE; did you mean %qs?",
                     token->value, hint);

to make the change from taking a location_t to a rich_location *.

This patch renames the "*_at_rich_loc" diagnostic entrypoints to use
the same function names for rich_location * as for location_t,
via overloading, to simplify the above change to just changing from:

  error_at (token->location,
            "unknown type name %qE; did you mean %qs?",
            token->value, hint);
to:

  gcc_rich_location richloc (token->location);
  richloc.add_fixit_replace (hint);
  error_at (&richloc,
            "unknown type name %qE; did you mean %qs?",
            token->value, hint);

thus saving space (and typing) and usually avoiding the need to reindent
the "error_at" invocation.

With this change, 0 is no longer acceptable as a location_t to these
entrypoints, as e.g.:

../../src/gcc/auto-profile.c:855:37: error: call of overloaded
'inform(int, const char [18])' is ambiguous
       inform (0, "Not expected TAG.");
                                     ^
In file included from ../../src/gcc/auto-profile.c:35:0:
../../src/gcc/diagnostic-core.h:88:13: note: candidate:
'void inform(location_t, const char*, ...)'
 extern void inform (location_t, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3);
             ^~~~~~
../../src/gcc/diagnostic-core.h:89:13: note: candidate:
'void inform(rich_location*, const char*, ...)'
 extern void inform (rich_location *, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3);
             ^~~~~~

Such locations now need to be spelled out as UNKNOWN_LOCATION,
rather than 0.

I considered making the API take a rich_location & rather than a
rich_location *, but doing so would mean replacing
  diagnostic_set_info
and
  diagnostic_set_info_translated
with a constructor for diagnostic_info, which was a more invasive
change.  Maybe in the future.

Add -std=c17, -std=gnu17. · c76dc9c3

C17, a bug-fix version of the C11 standard with DR resolutions
integrated, will soon go to ballot.  This patch adds corresponding
options -std=c17, -std=gnu17 (new default version, replacing
-std=gnu11 as the default), -std=iso9899:2017.  As a bug-fix version
of the standard, there is no need for flag_isoc17 or any options for
compatibility warnings; however, there is a new __STDC_VERSION__
value, so new cpplib languages CLK_GNUC17 and CLK_STDC17 are added to
support using that new value with the new options.  (If the standard
ends up being published in 2018 and being known as C18, option aliases
can be added.  Note however that -std=iso9899:199409 corresponds to a
__STDC_VERSION__ value rather than a publication date.)

(There are a couple of DR resolutions needing implementing in GCC, but
that's independent of the new options.)

(I'd propose to add -std=c2x / -std=gnu2x / -Wc11-c2x-compat for the
next major C standard revision once there are actually C2x drafts
being issued with new features included.)

Bootstrapped with no regressions for x86_64-pc-linux-gnu.

gcc:
	* doc/invoke.texi (C Dialect Options): Document -std=c17,
	-std=iso9899:2017 and -std=gnu17.
	* doc/standards.texi (C Language): Document C17 support.
	* doc/cpp.texi (Overview): Mention -std=c17.
	(Standard Predefined Macros): Document C11 and C17 values of
	__STDC_VERSION__.  Do not refer to C99 support as incomplete.
	* doc/extend.texi (Inline): Do not list individual options for
	standards newer than C99.
	* dwarf2out.c (highest_c_language, gen_compile_unit_die): Handle
	"GNU C17".
	* config/rl78/rl78.c (rl78_option_override): Handle "GNU C17"
	language name.

	* c-opts.c (set_std_c17): New function.
	(c_common_init_options): Use gnu17 as default C version.
	(c_common_handle_option): Handle -std=c17 and -std=gnu17.

	* include/cpplib.h (enum c_lang): Add CLK_GNUC17 and CLK_STDC17.
	* init.c (lang_defaults): Add GNUC17 and STDC17 data.
	(cpp_init_builtins): Handle C17 value of __STDC_VERSION__.

Prevent fix-it hints from affecting more than one line · c7a980b8

Attempts to apply a removal or replacement fix-it hint to a source
range that covers multiple lines currently lead to nonsensical
results from the printing code in diagnostic-show-locus.c.

We were already filtering them out in edit-context.c (leading
to -fdiagnostics-generate-patch not generating any output for
the whole TU).

Reject attempts to add such fix-it hints within rich_location,
fixing the diagnostic-show-locus.c issue.

gcc/ChangeLog:
	* diagnostic-show-locus.c
	(selftest::test_fixit_deletion_affecting_newline): New function.
	(selftest::diagnostic_show_locus_c_tests): Call it.

libcpp/ChangeLog:
	* include/line-map.h (class rich_location): Document that attempts
	to delete or replace a range *affecting* multiple lines will fail.
	* line-map.c (rich_location::maybe_add_fixit): Implement this
	restriction.
