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.

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.)

The existing directives-only code (a) punched a hole through the
libcpp interface and (b) didn't support raw string literals. This
reimplements this preprocessing mode. I added a proper callback
interface, and adjusted c-ppoutput to use it. Sadly I cannot get rid
of the libcpp/internal.h include for unrelated reasons.
The new scanner is in lex.x, and works doing some backwards scanning
when it finds a charater of interest. This reduces the number of
cases one has to deal with in forward scanning. It may have different
failure mode than forward scanning on bad tokenization.

The clever hack of '#define __has_include __has_include' breaks -dD
and -fdirectives-only, because that emits definitions. This turns
__has_include into a proper builtin macro. Thus it's never emitted
via -dD, and because use outside of directive processing is undefined,
we can just expand it anywhere.

__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.

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.

ISO C2x adds decimal floating point as an optional standard feature.
This patch accordingly makes GCC accept DFP constants (DF, DD, DL, df,
dd, dl suffixes) in strict C2X mode, with a pedwarn-if-pedantic for
older standards and a warning with -Wc11-c2x-compat even in C2x mode
(which in turn requires -Wc11-c2x-compat to be newly passed through to
libcpp).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

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.

Now new features are starting to be added to a C2X draft (in the C2x
branch of the C standard git repository, no public WG14 document yet),
it's time to add -std=c2x and associated options to GCC for use in
enabling C2X features.
This patch adds the expected set of options: -std=c2x, -std=gnu2x,
-Wc11-c2x-compat. A first C2X feature is added (the only one so far
in the repository that's obviously relevant to GCC): support (as in
C++) for the string constant to be omitted in _Static_assert. This
feature is duly also supported as an extension in earlier standard
modes (diagnosed with -pedantic, unless -Wno-c11-c2x-compat is given,
or with -Wc11-c2x-compat even in C2X mode).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

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).

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.

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.

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.

ISO/IEC TS 18661-3:2015 defines C bindings to IEEE interchange and
extended types, in the form of _FloatN and _FloatNx type names with
corresponding fN/FN and fNx/FNx constant suffixes and FLTN_* / FLTNX_*
<float.h> macros. This patch implements support for this feature in
GCC.
The _FloatN types, for N = 16, 32, 64 or >= 128 and a multiple of 32,
are types encoded according to the corresponding IEEE interchange
format (endianness unspecified; may use either the NaN conventions
recommended in IEEE 754-2008, or the MIPS NaN conventions, since the
choice of convention is only an IEEE recommendation, not a
requirement). The _FloatNx types, for N = 32, 64 and 128, are IEEE
"extended" types: types extending a narrower format with range and
precision at least as big as those specified in IEEE 754 for each
extended type (and with unspecified representation, but still
following IEEE semantics for their values and operations - and with
the set of values being determined by the precision and the maximum
exponent, which means that while Intel "extended" is suitable for
_Float64x, m68k "extended" is not). These types are always distinct
from and not compatible with each other and the standard floating
types float, double, long double; thus, double, _Float64 and _Float32x
may all have the same ABI, but they are three still distinct types.
The type names may be used with _Complex to construct corresponding
complex types (unlike __float128, which acts more like a typedef name
than a keyword - thus, this patch may be considered to fix PR
c/32187). The new suffixes can be combined with GNU "i" and "j"
suffixes for constants of complex types (e.g. 1.0if128, 2.0f64i).
The set of types supported is implementation-defined. In this GCC
patch, _Float32 is SFmode if that is suitable; _Float32x and _Float64
are DFmode if that is suitable; _Float128 is TFmode if that is
suitable; _Float64x is XFmode if that is suitable, and otherwise
TFmode if that is suitable. There is a target hook to override the
choices if necessary. "Suitable" means both conforming to the
requirements of that type, and supported as a scalar type including in
libgcc. The ABI is whatever the back end does for scalars of that
mode (but note that _Float32 is passed without promotion in variable
arguments, unlike float). All the existing issues with exceptions and
rounding modes for existing types apply equally to the new type names.
No GCC port supports a floating-point format suitable for _Float128x.
Although there is HFmode support for ARM and AArch64, use of that for
_Float16 is not enabled. Supporting _Float16 would require additional
work on the excess precision aspects of TS 18661-3: there are new
values of FLT_EVAL_METHOD, which are not currently supported in GCC,
and FLT_EVAL_METHOD == 0 now means that operations and constants on
types narrower than float are evaluated to the range and precision of
float. Implementing that, so that _Float16 gets evaluated with excess
range and precision, would involve changes to the excess precision
infrastructure so that the _Float16 case is enabled by default, unlike
the x87 case which is only enabled for -fexcess-precision=standard.
Other differences between _Float16 and __fp16 would also need to be
disentangled.
GCC has some prior support for nonstandard floating-point types in the
form of __float80 and __float128. Where these were previously types
distinct from long double, they are made by this patch into aliases
for _Float64x / _Float128 if those types have the required properties.
In principle the set of possible _FloatN types is infinite. This
patch hardcodes the four such types for N <= 128, but with as much
code as possible using loops over types to minimize the number of
places with such hardcoding. I don't think it's likely any further
such types will be of use in future (or indeed that formats suitable
for _Float128x will actually be implemented). There is a corner case
that all _FloatN, for N >= 128 and a multiple of 32, should be treated
as keywords even when the corresponding type is not supported; I
intend to deal with that in a followup patch.
Tests are added for various functionality of the new types, mostly
using type-generic headers. The tests use dg-add-options to pass any
extra options needed to enable the types; this is wired up to use the
same options as for __float128 on powerpc to enable _Float128 and
_Float64x, and effective-target keywords for runtime support do the
same hardware test as for __float128 to make sure the VSX instructions
generated by those options are supported. (Corresponding additions
would be needed for _Float16 on ARM as well if that were enabled with
-mfp16-format=ieee required to use it rather than unconditionally
available. Of course, -mfp16-format=alternative enables use of a
format which is not compatible with the requirements of the _Float16
type.)
C++ note: no support for the new types or constant suffixes is added
for C++. C++ decimal floating-point support was very different from
the C support, using class types, and the same may well apply to any
future C++ bindings for IEEE interchange and extended types. There is
a case, however, for supporting at least *f128 constants in C++, so
that code using __float128 can use the newer style for constants
throughout rather than needing to use the older *q constants in C++.
Also, if built-in functions are added that may provide a way in which
the types could leak into C++ code.
Fortran note: the float128_type_node used in the Fortran front end is
renamed to gfc_float128_type_node, since the semantics are different:
in particular, if long double has binary128 format, then the new
language-independent float128_type_node is a distinct type that also
has binary128 format, but the Fortran node is expected to be NULL in
that case. Likewise, Fortran's complex_float128_type_node is renamed
to gfc_complex_float128_type_node.
PowerPC note: the back end had an inconsistency that if TFmode was
binary128, *q constants were TFmode instead of KFmode but __float128
was KFmode. This patch follows the same logic as for *q constants, so
that _Float128 prefers TFmode (and __float128 becomes an alias for
_Float128).
ARM note: __fp16 is promoted to double (by convert_arguments) when
passed without a prototype / in variable arguments. But this is only
about the argument promotion; it is not handled as promoting in
c-common.c:self_promoting_args_p / c-typeck.c:c_type_promotes_to,
meaning that a K&R function definition for an argument of type __fp16
corresponds to a prototype with an argument of that type, not to one
with an argument of type double, whereas a float argument in a K&R
function definition corresponds to a double prototype argument - and
the same functions are also what's involved in making va_arg give a
warning and generate a call to abort when called with type float.
This is preserved by this patch, while arranging for _Float16 not to
be promoted when passed without a prototype / in variable arguments
(the promotion of float being considered a legacy feature, not applied
to any new types in C99 or later).
TS 18661-3 extends the set of decimal floating-point types similarly,
and adds new constant suffixes for the existing types, but this patch
does not do anything regarding that extension.
This patch does nothing regarding built-in functions, although
type-generic functions such as __builtin_isinf work for the new types
and associated tests are included. There are at least two levels of
built-in function support possible for these types. The minimal
level, implemented in
<https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01702.html> (which
needs updating to use dg-add-options), adds built-in functions similar
to those x86 has for __float128: __builtin_inf* __builtin_huge_val*,
__builtin_nan*, __builtin_nans*, __builtin_fabs*, __builtin_copysign*.
That would be sufficient for glibc to use the *f128 names for built-in
functions by default with *q used only for backwards compatibility
when using older GCC versions. That would also allow c_cpp_builtins's
flag_building_libgcc code, defining __LIBGCC_%s_FUNC_EXT__, to use
such suffixes rather than the present code hardcoding logic about
target-specific constant suffixes and how those relate to function
suffixes.
Full built-in function support would cover the full range of built-in
functions for existing floating-point types, adding variants for all
the new types, except for a few obsolescent functions and
non-type-generic variants of type-generic functions. Some but not all
references to such functions in GCC use macros such as CASE_FLT_FN to
be type-generic; a fair amount of work would be needed to identify all
places to update. Adding all those functions would enable
optimizations (for constant arguments and otherwise) for TS 18661-3
functions, but it would also substantially expand the enum listing
built-in functions (and we've had problems with the size of that enum
in the past), and increase the amount of built-in function
initialization to do - I don't know what the startup cost involved in
built-in function initialization is, but it would be something to
consider when adding such a large set of functions.
There are also a range of optimizations, in match.pd and elsewhere,
that only operate on the three standard floating-point types. Ideally
those would be made generic to all floating-point types, but this
patch does nothing in that regard. Special care would be needed
regarding making sure library functions to which calls are generated
actually exist. For example, if sqrt is called on an argument of type
_Float32, and the result converted to _Float32, this is equivalent to
doing a square root operation directly on _Float32. But if the user's
libm does not have the sqrtf32 function, or the name is not reserved
because __STDC_WANT_IEC_60559_TYPES_EXT__ was not defined before
including <math.h>, you can only do that optimization if you convert
to a call to sqrtf instead.
DECIMAL_DIG now relates to all supported floating-point formats, not
just float, double and long double; I've raised the question with WG14
of how this relates to the formula for DECIMAL_DIG in C11 not
considering this. TS 18661-3 says it also covers non-arithmetic
formats only supported by library conversion functions; this patch
does not add any target hooks to allow for the case where there are
such formats wider than any supported for arithmetic types (where
e.g. libc supports conversions involving the binary128 representation,
but the _Float128 type is not supported).
GCC provides its own <tgmath.h> for some targets. No attempt is made
to adapt this to handle the new types.
Nothing is done regarding debug info for the new types (see the
"Debugger support for __float128 type?" thread on gcc@, Sep/Oct 2015).
No __SIZEOF_*__ macros are added for the new types.
Nothing is done with do_warn_double_promotion.
Nothing is done to include the new types in those determining
max_align_t, although properly it should be sufficiently aligned for
any of those types.
The logic for usual arithmetic conversions in c_common_type relies on
TYPE_PRECISION for floating-point types, which is less than ideal
(doesn't necessarily correspond to whether one type's values are
subset of another); looking in more detail at the formats might be
better. But since I included code in build_common_tree_nodes to work
around rs6000 KFmode having precision 113 not 128, I think it should
work. Ideally one might have errors in generic code for the case
where the two types do not have one type's values a subset of the
other (which is undefined behavior). But the only case where this can
actually occur is mixing IBM long double with binary128 on powerpc,
and rs6000_invalid_binary_op deals with that at present. TS 18661-3
does not fully specify the type resulting from the usual arithmetic
conversions in the case where two _FloatNx types have the same set of
values; I arranged the code to prefer the greater value of N in that
case.
The __FP_FAST_FMA* macros are not extended to cover the new types,
since there are no corresponding built-in functions (if built-in
fmafN, fmafNx are added, the macros should be extended, and the new
macros documented). Also, only a limited set of modes is handled in
mode_has_fma.
Diagnostics relating to the use of the new types with -pedantic do not
try to distinguish them from purely nonstandard types such as __int128
and constant suffixes such as *q.
If you use an unsupported _FloatN / _FloatNx type you get a warning
about the type defaulting to int after the warning about the type not
being supported. That's less than ideal, but it's also a pre-existing
condition if you use __int128 on a 32-bit system where it's
unsupported.
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Other
back-end changes minimally tested by building cc1 for ia64-linux-gnu,
powerpc64le-linux-gnu, pdp11-none (the last failed for unrelated
reasons).
