libcpp: Implement C++23 P1949R7 - C++ Identifier Syntax using Unicode Standard Annex 31
The following patch implements the
P1949R7 - C++ Identifier Syntax using Unicode Standard Annex 31
paper. We already allow UTF-8 characters in the source, so that part
is already implemented, so IMHO all we need to do is pedwarn instead of
just warn for the (default) -Wnormalize=nfc (or for -Wnormalize={id,nkfc})
if the character is not in NFC and to use the unicode XID_Start and
XID_Continue derived code properties to find out what characters are allowed
(the standard actually adds U+005F to XID_Start, but we are handling the
ASCII compatible characters differently already and they aren't allowed
in UCNs in identifiers). Instead of hardcoding the large tables
in ucnid.tab, this patch makes makeucnid.c read them from the Unicode
tables (13.0.0 version at this point).
For non-pedantic mode, we accept as 2nd+ char in identifiers a union
of valid characters in all supported modes, but for the 1st char it
was actually pedantically requiring that it is not any of the characters
that may not appear in the currently chosen standard as the first character.
This patch changes it such that also what is allowed at the start of an
identifier is a union of characters valid at the start of an identifier
in any of the pedantic modes.

c: Add support for __FILE_NAME__ macro (PR c/42579)
The toolchain provided by ST for stm32 has had support for __FILENAME__ for a while, but clang/llvm has recently implemented support for __FILE_NAME__, so it seems better to use the same macro name in GCC. It happens that the ST patch is similar to the one proposed in PR c/42579. Given these input files: :::::::::::::: mydir/myinc.h :::::::::::::: char* mystringh_file = __FILE__; char* mystringh_filename = __FILE_NAME__; char* mystringh_base_file = __BASE_FILE__; :::::::::::::: mydir/mysrc.c :::::::::::::: char* mystring_file = __FILE__; char* mystring_filename = __FILE_NAME__; char* mystring_base_file = __BASE_FILE__; we produce: $ gcc mydir/mysrc.c -I . -E char* mystringh_file = "./mydir/myinc.h"; char* mystringh_filename = "myinc.h"; char* mystringh_base_file = "mydir/mysrc.c"; char* mystring_file = "mydir/mysrc.c"; char* mystring_filename = "mysrc.c"; char* mystring_base_file = "mydir/mysrc.c"; 2021-05-20 Christophe Lyon <christophe.lyon@linaro.org> Torbjörn Svensson <torbjorn.svensson@st.com> PR c/42579 libcpp/ * include/cpplib.h (cpp_builtin_type): Add BT_FILE_NAME entry. * init.c (builtin_array): Likewise. * macro.c (_cpp_builtin_macro_text): Add support for BT_FILE_NAME. gcc/ * doc/cpp.texi (Common Predefined Macros): Document __FILE_NAME__. gcc/testsuite/ * c-c++-common/spellcheck-reserved.c: Add tests for __FILE_NAME__. * c-c++-common/cpp/file-name-1.c: New test. |

preprocessor: Support C2X #elifdef, #elifndef
C2X adds #elifdef and #elifndef preprocessor directives; these have also been proposed for C++. Implement these directives in libcpp accordingly. In this implementation, #elifdef and #elifndef are treated as non-directives for any language version other than c2x and gnu2x (if the feature is accepted for C++, it can trivially be enabled for relevant C++ versions). In strict conformance modes for prior language versions, this is required, as illustrated by the c11-elifdef-1.c test added. Bootstrapped with no regressions for x86_64-pc-linux-gnu. libcpp/ * include/cpplib.h (struct cpp_options): Add elifdef. * init.c (struct lang_flags): Add elifdef.

Fix thinko in libcpp preparation patch for modules
The problem is that the new IS_MACRO_LOC macro:
inline bool
IS_MACRO_LOC (location_t loc)
{
return !IS_ORDINARY_LOC (loc) && !IS_ADHOC_LOC (loc);
}
is not fully correct since the position of the macro lines is not fixed:
/* Returns the lowest location [of a token resulting from macro
expansion] encoded in this line table. */
inline location_t
LINEMAPS_MACRO_LOWEST_LOCATION (const line_maps *set)
{
return LINEMAPS_MACRO_USED (set)
? MAP_START_LOCATION (LINEMAPS_LAST_MACRO_MAP (set))
: MAX_LOCATION_T + 1;
}
In Ada, LINEMAPS_MACRO_USED is false so LINEMAPS_MACRO_LOWEST_LOCATION is
MAX_LOCATION_T + 1, but IS_MACRO_LOC nevertheless returns true for anything
in the range [LINE_MAP_MAX_LOCATION; MAX_LOCATION_T], thus yielding an ICE
in linemap_macro_map_lookup for very large files.

c++: Macro location fixes [PR 98718]
This fixes some issues with macro maps. We were incorrectly calculating the number of macro expansions in a location span, and I had a workaround that partially covered that up. Further, while macro location spans are monotonic, that is not true of ordinary location spans. Thus we need to insert an indirection array when binary searching the latter. (We load ordinary locations before loading imports, but macro locations afterwards. We make sure an import location is de-macrofied, if needed.)

c++: header-unit build capability [PR 99023]
This defect really required building header-units and include translation of pieces of the standard library. This adds smarts to the modules test harness to do that -- accept .X files as the source file, but provide '-x c++-system-header $HDR' in the options. The .X file will be considered by the driver to be a linker script and ignored (with a warning). Using this we can add 2 tests that end up building list_initializer and iostream, along with a test that iostream's build include-translates list_initializer's #include. That discovered a set of issues with the -flang-info-include-translate=HDR handling, also fixed and documented here.

preprocessor: Add deferred macros
Deferred macros are needed for C++ modules. Header units may export macro definitions and undefinitions. These are resolved lazily at the point of (potential) use. (The language specifies that, it's not just a useful optimization.) Thus, identifier nodes grow a 'deferred' field, which fortunately doesn't expand the structure on 64-bit systems as there was padding there. This is non-zero on NT_MACRO nodes, if the macro is deferred. When such an identifier is lexed, it is resolved via a callback that I added recently. That will either provide the macro definition, or discover it there was an overriding undef. Either way the identifier is no longer a deferred macro. Notice it is now possible for NT_MACRO nodes to have a NULL macro expansion. libcpp/ * include/cpplib.h (struct cpp_hashnode): Add deferred field. (cpp_set_deferred_macro): Define.

preprocessor: C++ module-directives
C++20 modules introduces a new kind of preprocessor directive -- a module directive. These are directives but without the leading '#'. We have to detect them by sniffing the start of a logical line. When detected we replace the initial identifiers with unspellable tokens and pass them through to the language parser the same way deferred pragmas are. There's a PRAGMA_EOL at the logical end of line too. One additional complication is that we have to do header-name lexing after the initial tokens, and that requires changes in the macro-aware piece of the preprocessor. The above sniffer sets a counter in the lexer state, and that triggers at the appropriate point. We then do the same header-name lexing that occurs on a #include directive or has_include pseudo-macro. Except that the header name ends up in the token stream. A couple of token emitters need to deal with the new token possibility. gcc/c-family/ * c-lex.c (c_lex_with_flags): CPP_HEADER_NAMEs can now be seen. libcpp/ * include/cpplib.h (struct cpp_options): Add module_directives option.

This patch adds LC_MODULE as a map kind, used to indicate a c++ module. Unlike a regular source file, it only contains a single location, and the source locations in that module are represented by ordinary locations whose 'included_from' location is the module.

c: C2x __has_c_attribute
C2x adds the __has_c_attribute preprocessor operator, similar to C++ __has_cpp_attribute. GCC implements __has_cpp_attribute as exactly equivalent to __has_attribute. (The documentation says they differ regarding the values returned for standard attributes, but that's actually only a matter of the particular nonzero value returned not being specified in the documentation for __has_attribute; the implementation makes no distinction between the two.) I don't think having them exactly equivalent is actually correct, either for __has_cpp_attribute or for __has_c_attribute. Specifically, I think it is only correct for __has_cpp_attribute or __has_c_attribute to return nonzero if the given attribute is supported, with the particular pp-tokens passed to __has_cpp_attribute or __has_c_attribute, with [[]] syntax, not if it's only accepted in __attribute__ or with gnu:: added in [[]]. For example, they should return nonzero for gnu::packed, but zero for plain packed, because [[gnu::packed]] is accepted but [[packed]] is ignored as not a standard attribute. This patch implements that for __has_c_attribute, leaving any changes to __has_cpp_attribute for the C++ maintainers. A new BT_HAS_STD_ATTRIBUTE is added for __has_c_attribute (which I think, based on the above, would actually be correct to use for __has_cpp_attribute as well). The code in c_common_has_attribute that deals with scopes has its C++ conditional removed; instead, whether the language is C or C++ is used only to determine the numeric values returned for standard attributes (and which standard attributes are handled there at all). A new argument is passed to c_common_has_attribute to distinguish BT_HAS_STD_ATTRIBUTE from BT_HAS_ATTRIBUTE, and that argument is used to stop attributes with no scope specified from being accepted with __has_c_attribute unless they are one of the known standard attributes and so handled specially. Although the standard specify constants ending with 'L' as the values for the standard attributes, there is no correctness issue with the lack of code in GCC to add that 'L' to the expansion: __has_c_attribute and __has_cpp_attribute are expanded in #if after other macro expansion has occurred, with no semantics being specified if they occur outside #if, so there is no way for a conforming program to inspect the exact text of the expansion of those macros, only to use the resulting pp-number in a #if expression, where long and int have the same set of values.

libcpp: Provide date routine
Joseph pointed me at cb_get_source_date_epoch, which allows repeatable builds and solves a FIXME I had on the modules branch. Unfortunately it's used exclusively to generate __DATE__ and __TIME__ values, which fallback to using a time(2) call. It'd be nicer if the preprocessor made whatever time value it determined available to the rest of the compiler. So this patch adds a new cpp_get_date function, which abstracts the call to the get_source_date_epoch hook, or uses time directly. The value is cached. Thus the timestamp I end up putting on CMI files matches __DATE__ and __TIME__ expansions. That seems worthwhile. libcpp/ * include/cpplib.h (enum class CPP_time_kind): New.

c-family: Macro support in -Wmisleading-indentation [PR80076]
Currently the -Wmisleading-indentation warning doesn't do any analysis
when the guarded statement or the statement after it is produced by a
macro. This means we warn for:
if (flag)
foo ();
bar ();
but not for:
#define BAR bar
if (flag)
foo ();
BAR ();
This patch extends the -Wmisleading-indentation implementation to
support analyzing such statements and their tokens. This is done in the
"natural" way by resolving the location of each of the three tokens to
the token's macro expansion point. (Additionally, if the tokens all
resolve to the same macro expansion point then we instead use their
locations within the macro definition.) When these resolved locations
are all different, then we can proceed with applying the warning
heuristics to them as if no macros were involved.

* c-indentation.c (should_warn_for_misleading_indentation): Move

preprocessor: Better line info for <builtin> & <command-line>
With C++ module header units it becomes important to distinguish
between macros defined in forced headers (& commandline & builtins)
from those defined in the header file being processed. We weren't
making that easy because we treated the builtins and command-line
locations somewhat file-like, with incrementing line numbers, and
showing them as included from line 1 of the main file. This patch does
3 things:
0) extend the idiom that 'line 0' of a file means 'the file as a whole'
1) builtins and command-line macros are shown as-if included from line zero.
2) when emitting preprocessed output we keep resetting the line number
so that re-reading that preprocessed output will get the same set of
locations for the command line etc.
For instance the new c-c++-common/cpp/line-2.c test, now emits
In file included from <command-line>:
./line-2.h:4:2: error: #error wrong
4 | #error wrong
| ^~~~~
line-2.c:3:11: error: macro "bill" passed 1 arguments, but takes just 0
3 | int bill(1);
| ^
In file included from <command-line>:
./line-2.h:3: note: macro "bill" defined here
3 | #define bill() 2
|
Before it told you about including from <command-line>:31.
the preprocessed output looks like:
...
(There's a new optimization in do_line_marker to stop each of these
line markers causing a new line map. We can simply rewind the
location, and keep using the same line map.)

[PR 80005] Fix __has_include
__has_include is funky in that it is macro-like from the POV of #ifdef and
friends, but lexes its parenthesize argument #include-like. We were
failing the second part of that, because we used a forwarding macro to an
internal name, and hence always lexed the argument in macro-parameter
context. We componded that by not setting the right flag when lexing, so
it didn't even know. Mostly users got lucky.
This reimplements the handline.
1) Remove the forwarding, but declare object-like macros that
expand to themselves. This satisfies the #ifdef requirement
2) Correctly set angled_brackets when lexing the parameter. This tells
the lexer (a) <...> is a header name and (b) "..." is too (not a string).
3) Remove the in__has_include lexer state, just tell find_file that that's
what's happenning, so it doesn't emit an error.
We lose the (undocumented) ability to #undef __has_include. That may well
have been an accident of implementation. There are no tests for it.
We gain __has_include behaviour for all users of the preprocessors -- not
just the C-family ones that defined a forwarding macro.

Add diagnostic paths
This patch adds support for associating a "diagnostic_path" with a
diagnostic: a sequence of events predicted by the compiler that leads to
the problem occurring, with their locations in the user's source,
text descriptions, and stack information (for handling interprocedural
paths).
For example, the following (hypothetical) error has a 3-event
intraprocedural path:
test.c: In function 'demo':
test.c:29:5: error: passing NULL as argument 1 to 'PyList_Append' which
requires a non-NULL parameter
29 | PyList_Append(list, item);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
'demo': events 1-3
|
| 25 | list = PyList_New(0);
| | ^~~~~~~~~~~~~
| | |
| | (1) when 'PyList_New' fails, returning NULL
| 26 |
| 27 | for (i = 0; i < count; i++) {
| | ~~~
| | |
| | (2) when 'i < count'
| 28 | item = PyLong_FromLong(random());
| 29 | PyList_Append(list, item);
| | ~~~~~~~~~~~~~~~~~~~~~~~~~
| | |
| | (3) when calling 'PyList_Append', passing NULL from (1) as argument 1
|
The patch adds a new "%@" format code for printing event IDs, so that
in the above, the description of event (3) mentions event (1), showing
the user where the bogus NULL value comes from (the event IDs are
colorized to draw the user's attention to them).
There is a separation between data vs presentation: the above shows how
the diagnostic-printing code has consolidated the path into a single run
of events, since all the events are near each other and within the same
function; more complicated examples (such as interprocedural paths)
might be printed as multiple runs of events.
Examples of how interprocedural paths are printed can be seen in the
test suite (which uses a plugin to exercise the code without relying
on specific warnings using this functionality).
Other output formats include
- JSON,
- printing each event as a separate "note", and
- to not emit paths.

Implement C++20 operator<=>.
There are three major pieces to this support: scalar operator<=>,
synthesis of comparison operators, and rewritten/reversed overload
resolution (e.g. a < b becomes 0 > b <=> a).
Unlike other defaulted functions, where we use synthesized_method_walk to
semi-simulate what the definition of the function will be like, this patch
determines the characteristics of a comparison operator by trying to define
it.
My handling of non-dependent rewritten operators in templates can still use
some work: build_min_non_dep_op_overload can't understand the rewrites and
crashes, so I'm avoiding it for now by clearing *overload. This means we'll
do name lookup again at instantiation time, which can incorrectly mean a
different result. I'll poke at this more in stage 3.
I'm leaving out a fourth section ("strong structural equality") even though
I've implemented it, because it seems likely to change radically tomorrow.
Thanks to Tim van Deurzen and Jakub for implementing lexing of the <=>
operator, and Jonathan for the initial <compare> header.

Handle :: tokens in C for C2x.
As part of adding [[]]-style attributes, C2x adds the token :: for use in scoped attribute names. This patch adds corresponding support for that token in C to GCC. The token is supported both for C2x and for older gnu* standards (on the basis that extensions are normally supported in older gnu* versions; people will expect to be able to use [[]] attributes, before C2x is the default, without needing to use -std=gnu2x). There are no cases in older C standards where the token : can be followed by a token starting with : in syntactically valid sources; the only cases the :: token could break in older standard C thus are ones involving concatenation of pp-tokens where the result does not end up as tokens (e.g., gets stringized). In GNU C extensions, the main case where :: might appear in existing sources is in asm statements, and the C parser is thus made to handle it like two consecutive : tokens, which the C++ parser already does. A limited test of various positionings of :: in asm statements is added to the testsuite (in particular, to cover the syntax error when :: means too many colons but a single : would be OK), but existing tests cover a variety of styles there anyway. Technically there are cases in Objective-C and OpenMP for which this also changes how previously valid code is lexed: the objc-selector-arg syntax allows multiple consecutive : tokens (although I don't think they are particularly useful there), while OpenMP syntax includes array section syntax such as [:] which, before :: was a token, could also be written as [::> (there might be other OpenMP cases potentially affected, I didn't check all the OpenMP syntax in detail). I don't think either of those cases affects the basis for supporting the :: token in all -std=gnu* modes, or that there is any obvious need to special-case handling of CPP_SCOPE tokens for those constructs the way there is for asm statements. cpp_avoid_paste, which determines when spaces need adding between tokens in preprocessed output where there wouldn't otherwise be whitespace between them (e.g. if stringized), already inserts space between : and : unconditionally, rather than only for C++, so no change is needed there (but a C2x test is added that such space is indeed inserted). Bootstrapped with no regressions on x86-64-pc-linux-gnu. gcc/c: * c-parser.c (c_parser_asm_statement): Handle CPP_SCOPE like two CPP_COLON tokens. gcc/testsuite: * gcc.dg/asm-scope-1.c, gcc.dg/cpp/c11-scope-1.c, gcc.dg/cpp/c17-scope-1.c, gcc.dg/cpp/c2x-scope-1.c, gcc.dg/cpp/c2x-scope-2.c, gcc.dg/cpp/c90-scope-1.c, gcc.dg/cpp/c94-scope-1.c, gcc.dg/cpp/c99-scope-1.c, gcc.dg/cpp/gnu11-scope-1.c, gcc.dg/cpp/gnu17-scope-1.c, gcc.dg/cpp/gnu89-scope-1.c, gcc.dg/cpp/gnu99-scope-1.c: New tests. libcpp: * include/cpplib.h (struct cpp_options): Add member scope. * init.c (struct lang_flags, lang_defaults): Likewise.

Fix ICE with #line directive (PR c/89410)
PR c/89410 reports various issues with #line directives with very large numbers; one of them is an ICE inside diagnostic-show-locus.c when emitting a diagnostic at line 0xffffffff. The issue is that the arithmetic in layout::calculate_line_spans to determine if two line spans are sufficiently close to consolidate was using the unsigned 32-bit linenum_type, which was overflowing when comparing the line for the expanded location with those of the location range (all on line 0xffffffff), leading to it erroneously adding two spans for the same line, leading to an assertion failure. This patch fixes the ICE by generalizing the use of long long in line-map.h's comparison function for linenum_type into a new linenum_arith_t typedef, and using it here. Doing so uncovered a second problem: the loop to print the lines within the line_span for this case is infinite: looping from 0xfffffff upwards, overflowing to 0, and then never becoming greater than 0xfffffff. The patch fixes this by using linenum_arith_t there also. gcc/ChangeLog: PR c/89410 * diagnostic-show-locus.c (layout::calculate_line_spans): Use linenum_arith_t when determining if two adjacent line spans are close enough to merge. (diagnostic_show_locus): Use linenum_arith_t when iterating over lines within each line_span. gcc/testsuite/ChangeLog: PR c/89410 * gcc.dg/pr89410-1.c: New test. * gcc.dg/pr89410-2.c: New test. libcpp/ChangeLog: PR c/89410 * include/line-map.h (linenum_arith_t): New typedef.
