PR 62170 describes a problem with how the quoting in pp_format
interacts with the "aka" information for typedefs in %qT for
the C family of frontends, and also now for %qH and %qI in the
C++ frontend: we print:
'Py_ssize_t* {aka int*}'
^^^^^^^^^^^^^^^^^^^^^^ colorized as "quote"
i.e.
'[START_COLOR]Py_ssize_t* {aka int*}[END_COLOR]'
when we should print:
'Py_ssize_t*' {aka 'int*'}
^^^^^^^^^^^ ^^^^ colorized as "quote"
i.e.
'[START_COLOR]Py_ssize_t*[END_COLOR]' {aka '[START_COLOR]int*[END_COLOR]'}
where the opening and closing quote characters and colorization are
added by the 'q' handling within pp_format.
This patch fixes the quoting by updating the %T handling in C and C++
and the %H/%I handling in C++ to insert the quoting appropriately.
It converts the "quote" param of the pp_format_decoder callback from
bool to bool *, allowing for the %T and %H/%I handlers to write
false back to it, to avoid printing the closing quote for the cases
like the above where the trailing closing quote isn't needed.
It introduces pp_begin_quote/pp_end_quote to simplify this. These
take a "bool show_color", rather than using "pp_show_color (pp)"
since cxx_pp's pp_show_color isn't currently initialized (since
cxx_initialize_diagnostics happens before diagnostic_color_init).

PR c/83056 reports an issue affecting trunk and gcc-7 in which
the C frontend's implementation of lookup_name_fuzzy uses undeclared

The fix is to filter out the names bound to error_mark_node

This patch extends the C frontend's "knowledge" of the C stdlib within
get_c_name_hint to cover some more macros and functions, covering
a case reported in PR c/81404 ("INT_MAX"), so that rather than printing:
t.c:5:12: error: 'INT_MAX' undeclared here (not in a function); did you mean '__INT_MAX__'?
int test = INT_MAX;
^~~~~~~
__INT_MAX__
we instead print:
t.c:5:12: error: 'INT_MAX' undeclared here (not in a function)
int test = INT_MAX;
^~~~~~~
t.c:5:12: note: 'INT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?
t.c:1:1:
+#include <limits.h>
t.c:5:12:
int test = INT_MAX;
^~~~~~~
It also adds generalizes some of the code for this (and for the "std::"
namespace hints in the C++ frontend), moving it to a new
c-family/known-headers.cc and .h, and introducing a class known_headers.
This currently just works by scanning a hardcoded array of known
name/header associations, but perhaps in the future could be turned
into some kind of symbol database so that the compiler could record API
uses and use that to offer suggestions e.g.
foo.cc: error: 'myapi::foo' was not declared in this scope
foo.cc: note: 'myapi::foo" was declared in header 'myapi/private.h'
(included via 'myapi/public.h') when compiling 'bar.cc'; did you forget to
'#include "myapi/public.h"'?
or somesuch.
In any case, moving this to a class gives an easier way to locate the
hardcoded knowledge about the stdlib.
The patch also adds similar code to the C++ frontend covering
unqualified names in the standard library, so that rather than just
e.g.:
t.cc:19:13: error: 'NULL' was not declared in this scope
void *ptr = NULL;
^~~~
we can emit:
t.cc:19:13: error: 'NULL' was not declared in this scope
void *ptr = NULL;
^~~~
t.cc:19:13: note: 'NULL' is defined in header '<cstddef>'; did you forget
to '#include <cstddef>'?
t.cc:1:1:
+#include <cstddef>

The C frontend already "knows" about many common functions in
the C standard library:
test.c: In function 'test':
test.c:3:3: warning: implicit declaration of function 'printf' [-Wimplicit-function-declaration]
printf ("hello world\n");
^~~~~~
test.c:3:3: warning: incompatible implicit declaration of built-in function 'printf'
test.c:3:3: note: include '<stdio.h>' or provide a declaration of 'printf'
and which header file they are in.
However it doesn't know about various types and macros:
test.c:1:13: error: 'NULL' undeclared here (not in a function)
void *ptr = NULL;
^~~~
This patch uses the name_hint/deferred_diagnostic machinery to
add hints for missing C standard library headers for some of the
most common type and macro names.
For example, the above becomes:
test.c:1:13: error: 'NULL' undeclared here (not in a function)
void *ptr = NULL;
^~~~

In various places we use lookup_name_fuzzy to provide a hint,
and can report messages of the form:
error: unknown foo named 'bar'
or:
error: unknown foo named 'bar'; did you mean 'SUGGESTION?
This patch provides a way for lookup_name_fuzzy to provide
both the suggestion above, and (optionally) additional hints
that can be printed e.g.
note: did you forget to include <SOME_HEADER.h>?
This patch provides the mechanism and ports existing users
of lookup_name_fuzzy to the new return type.
There are no uses of such hints in this patch, but followup
patches provide various front-end specific uses of this.

Various implementations of C99/C11 <tgmath.h> have the property that
their macro expansions contain many copies of the macro arguments, so
resulting in exponential blowup of the size of macro expansions where
a call to such a macro contains other such calls in the macro
arguments.
This patch adds a (C-only) language feature __builtin_tgmath designed
to avoid this problem by implementing the <tgmath.h> function
selection rules directly in the compiler. The effect is that
type-generic macros can be defined simply as
#define pow(a, b) __builtin_tgmath (powf, pow, powl, \
cpowf, cpow, cpowl, a, b)
as in the example added to the manual, with each macro argument
expanded exactly once. The details of __builtin_tgmath are as
described in the manual. This is C-only since C++ uses function
overloading and just defines <ctgmath> to include <ccomplex> and
<cmath>.
__builtin_tgmath handles C99/C11 type-generic macros, and _FloatN,
_FloatNx and decimal floating-point types (following the proposed
resolution to the floating-point TS DR#9 that makes the rules for
finding a common type from arguments to a type-generic macro follow
the usual arithmetic conversions after adjustment of integer arguments
to _Decimal64 or double - or to _Complex double in the case of GNU
complex integer arguments).
Type-generic macros for functions from TS 18661 that round their
results to a narrower type are handled, but there are still some
unresolved questions regarding such macros so further changes in that
regard may be needed in future. The current implementation follows an
older version of the DR#13 resolution (allowing a function for a
wide-enough argument type to be selected if no exactly-matching
function is available), but with appropriate calls to __builtin_tgmath
is still fully compatible with the latest version of the resolution
(not yet in the DR log), and allowing such not-exactly-matching
argument types to be chosen in that case avoids needing another
special case to treat integers as _Float64 instead of double in
certain cases.
Regarding other possible language/library features, not currently
implemented in GCC:
* Imaginary types could be naturally supported by allowing cases where
the type-generic type is an imaginary type T and arguments or return
types may be T (as at present), or the corresponding real type to T
(as at present), or (new) the corresponding real type if T is real
or imaginary but T if T is complex. (tgmath.h would need a series
of functions such as
static inline _Imaginary double
__sin_imag (_Imaginary double __x)
{
return _Imaginary_I * sinh (__imag__ __x);
}
to be used in __builtin_tgmath calls.)
* __builtin_tgmath would use the constant rounding direction in the
presence of support for the FENV_ROUND / FENV_DEC_ROUND pragmas.
Support for those would also require a new __builtin_<something> to
cause a non-type-generic call to use the constant rounding
direction (it seems cleaner to add a new __builtin_<something> when
required than to make __builtin_tgmath handle a non-type-generic
case with only one function argument).
* TS 18661-5 __STDC_TGMATH_OPERATOR_EVALUATION__ would require new
__builtin_<something> that evaluates with excess range and precision
like arithmetic operators do.
* The proposed C bindings for IEEE 754-2018 augmented arithmetic
operations involve struct return types. As currently implemented
__builtin_tgmath does not handle those, but support could be added.
There are many error cases that the implementation diagnoses. I've
tried to ensure reasonable error messages for erroneous uses of
__builtin_tgmath, but the errors for erroneous uses of the resulting
type-generic macros (that is, when the non-function arguments have
inappropriate types) are more important as they are more likely to be
seen by users.
GCC's own tgmath.h, as used for some targets, is updated in this
patch. I've tested those changes minimally, via adjusting
gcc.dg/c99-tgmath-* locally to use that tgmath.h version. I've also
run the glibc testsuite (which has much more thorough tests of
correctness of tgmath.h function selection) with a glibc patch to use
__builtin_tgmath in glibc's tgmath.h.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

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.

c_parser_declaration_or_fndef has logic for parsing what might be
either a declaration or a function definition.
This patch adds a test to detect cases where a semicolon would have
terminated the decls as a declaration, where the token that follows
would start a new declaration specifier, and updates the error message
accordingly, with a fix-it hint.
This addresses PR c/7356, fixing the case of a stray token before a
#include that previously gave inscrutable output, and improving e.g.:
int i
int j;
from:
t.c:2:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'int'
int j;
^~~
to:
t.c:1:6: error: expected ';' before 'int'
int i
^
;
int j;
~~~
gcc.dg/noncompile/920923-1.c needs a slight update, as the output for
the first line changes from:
920923-1.c:2:14: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'unsigned'
typedef BYTE unsigned char; /* { dg-error "expected" } */
^~~~~~~~
to:
920923-1.c:2:13: error: expected ';' before 'unsigned'

^~~~~~~~~
;
920923-1.c:2:1: warning: useless type name in empty declaration

A proposal is to introduce a target independent flag
-fcf-protection=[none|branch|return|full] with a semantic to
instrument a code to control validness or integrity of control-flow
transfers using jump and call instructions. The main goal is to detect
and block a possible malware execution through transfer the execution
to unknown target address. Implementation could be either software or
target based. Any target platforms can provide their implementation
for instrumentation under this option.
The compiler should instrument any control-flow transfer points in a
program (ex. call/jmp/ret) as well as any landing pads, which are
targets of control-flow transfers.
A new 'nocf_check' attribute is introduced to provide hand tuning
support. The attribute directs the compiler to skip a call to a
function and a function's landing pad from instrumentation. The
attribute can be used for function and pointer to function types,
otherwise it will be ignored.
Currently all platforms except i386 will report the error and do no
instrumentation. i386 will provide the implementation based on a
specification published by Intel for a new technology called
Control-flow Enforcement Technology (CET).

The patch improves our C/C++ frontends' handling of missing
symbols, by making c_parser_require and cp_parser_require use
"better" locations for the diagnostic, and insert fix-it hints,
under certain circumstances (see the comments in the patch for
full details).
For example, for this code with a missing semicolon:
$ cat test.c
int missing_semicolon (void)
{
return 42
}
trunk currently emits:
test.c:4:1: error: expected ';' before '}' token
}
^
This patch adds a fix-it hint for the missing semicolon, and puts
the error at the location of the missing semicolon, printing the
followup token as a secondary location:
test.c:3:12: error: expected ';' before '}' token
return 42
^
;
}
~
More examples can be seen in the test cases.

The wide_int routines allow things like:
wi::add (t, 1)
to add 1 to an INTEGER_CST T in its native precision. But we also have:
wi::to_offset (t) // Treat T as an offset_int
wi::to_widest (t) // Treat T as a widest_int
Recently we also gained:
wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC
This patch therefore requires:
wi::to_wide (t)
when operating on INTEGER_CSTs in their native precision. This is
just as efficient, and makes it clearer that a deliberate choice is
being made to treat the tree as a wide_int in its native precision.
This also removes the inconsistency that
a) INTEGER_CSTs in their native precision can be used without an accessor
but must use wi:: functions instead of C++ operators
b) the other forms need an explicit accessor but the result can be used
with C++ operators.
It also helps with SVE, where there's the additional possibility
that the tree could be a runtime value.

In r253096
("C++: underline parameters in mismatching function calls"
aka 5d78d423a5f7a1d135c7bb678e82007678d1313c
https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01546.html )
I updated the C++ FE's handling of mismatched types in function calls
so that it underlines the pertinent param of the callee, rather than
just the function name.
The following patch does the same for the C frontend.
Given e.g. this type mismatch:
extern int callee (int one, const char *two, float three);
int caller (int first, int second, float third)
{
return callee (first, second, third);
}
the C FE currently emits (trunk):
test.c: In function 'caller':
test.c:5:25: warning: passing argument 2 of 'callee' makes pointer from
integer without a cast [-Wint-conversion]
return callee (first, second, third);
^~~~~~
test.c:1:12: note: expected 'const char *' but argument is of type 'int'
extern int callee (int one, const char *two, float three);
^~~~~~
whereas with this patch the note underlines the pertinent param of
the callee:
test.c: In function 'caller':
test.c:5:25: warning: passing argument 2 of 'callee' makes pointer from
integer without a cast [-Wint-conversion]
return callee (first, second, third);
^~~~~~
test.c:1:41: note: expected 'const char *' but argument is of type 'int'
extern int callee (int one, const char *two, float three);
~~~~~~~~~~~~^~~
making the problem more obvious to the user.
As with the C++ patch, the patch:
(a) updates the locations of the params to cover the range of all
of their tokens, putting the caret on the first character of the
param name (if present), otherwise at the start of the first token
(doing so requires adding a last_token_location to the c_parser, so
we can determine the location of the last consumed token).
(b) updates the "note" to use the param location, rather than the
fndecl location

C11 semantics for excess precision (from N1531) are that an implicit
conversion (from the usual arithmetic conversions, not by assignment)
from integer to floating point has a result in the corresponding
evaluation format of that floating-point type, so possibly with excess
precision (whereas a cast or conversion by assignment from integer to
floating point must produce a value without excess range or precision,
as always). This patch makes GCC support those semantics if
flag_isoc11 (which in turn means that conditional expressions need to
support generating a result with excess precision even if neither
operand had excess precision).
C99 is less than entirely clear in this regard, but my reading as
outlined at <https://gcc.gnu.org/ml/gcc-patches/2008-11/msg00105.html>
is that the results of conversions from integer to floating-point
types are always expected to be representable in the target type
without excess precision, and this patch conservatively keeps these
semantics for pre-C11 (i.e. if an older standard is explicitly
selected).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

PR c/82071 reports how compound assignment operators such as += handle
excess precision inconsistently with the same operation done with a
plain assignment and binary operator.
There were (at least) two problems with how compound assignments
handled excess precision. The EXCESS_PRECISION_EXPR for an argument
with excess precision was removed too early, resulting in
build_binary_op being called with an rhs operand whose type reflected
the evaluation format, so not having sufficient information to achieve
the intended semantics in all cases, and then the code called
c_fully_fold on the results of build_binary_op without allowing for
the possibility of an EXCESS_PRECISION_EXPR as the result, so leading
to double rounding of the result (first to its semantic type, then to
the type of the LHS of the assignment) instead of the intended single
rounding.
This patch fixes those problems by keeping EXCESS_PRECISION_EXPRs
further through build_modify_expr (and build_atomic_assign which it
calls) and only removing them locally where appropriate.
Note that while this patch should achieve *consistency*, that's
consistency with the understanding of C99 semantics that I originally
intended to implement. For the particular case in the testcase, C11
semantics (from N1531) differ from that understanding of C99
semantics, in that an implicit conversion of an integer to floating
point can have excess precision. I intend to implement those C11
semantics separately (conditional on flag_isoc11) (which will also
mean that building conditional expressions can produce a result with
excess precision even when the arguments lack excess precision, where
previously it could not), and not to close the bug until that is also
done.
Tested for x86_64-pc-linux-gnu.

In r251239 I added a c_expr::get_location method for use by
c_parser_expr_list for building the vec<location_t> for
an expression list, rather than using the location of the first token.
When determining whether to use the location within the tree node,
or fall back to the range in the c_expr, I used EXPR_CAN_HAVE_LOCATION,
rather than EXPR_HAS_LOCATION. This meant that any tree nodes of kinds
that *can* have a location but which erroneously had
EXPR_LOCATION (value) == UNKNOWN_LOCATION
had that value added to the vec<location_t>, leading to missing
location information when reporting on the issue
(seen with gcc.dg/Wtraditional-conversion-2.c for m68k).
This patch addresses this in two ways:
(a) it fixes the specific issue in this failing test case, by
setting up the location properly on the EXCESS_PRECISION_EXPR.
(b) updating c_expr::get_location by only using the EXPR_LOCATION
if it's sane. Arguably this is papering over bugs, but they are
pre-existing ones exposed by r251239, and I'd rather have this
fix in place than play whack-a-mole on any other such "missing
location" bugs that are lurking in the codebase.
gcc/c/ChangeLog:
* c-tree.h (c_expr::get_location) Use EXPR_HAS_LOCATION rather
than CAN_HAVE_LOCATION_P when determining whether to use the
location_t value within "value".
gcc/c-family/ChangeLog:
* c-lex.c (interpret_float): Use token location
when building an EXCESS_PRECISION_EXPR.

The previous patch uncovered a bug in how c_parser_expr_list builds the
vec<location_t>: it was only using the location of the first token
within each assignment-expression in the expr-list.
This shows up in e.g. this -Wformat warning, where only part of the
2nd param is underlined:
printf("hello %i", (long)0);
~^ ~
%li
This patch fixes c_parser_expr_list to use the full range of
each assignment-expression in the list for the vec<location_t>, so
that for the above we print:
printf("hello %i", (long)0);
~^ ~~~~~~~
%li
gcc/c/ChangeLog:
* c-parser.c (c_parser_expr_list): Use c_expr::get_location ()
rather than peeking the location of the first token.
* c-tree.h (c_expr::get_location): New method.
gcc/testsuite/ChangeLog:
* gcc.dg/format/diagnostic-ranges.c (test_mismatching_types):
Update expected result to show all of "(long)0" being underlined.

This patch passes along the vec<location_t> of argument locations
at a callsite from the C frontend to check_function_arguments and
from there to c-format.c, so that we can underline the pertinent
argument to mismatched format codes even for tree codes like decls
and constants which lack a location_t for their usage sites.
This takes e.g.:
printf("hello %i %i %i ", foo, bar, baz);
~^
%s
to:
printf("hello %i %i %i ", foo, bar, baz);
~^ ~~~
%s
which is useful for cases where there's more than one variadic argument.

Add warn_if_not_aligned attribute as well as command line options:
-Wif-not-aligned and -Wpacked-not-aligned.
__attribute__((warn_if_not_aligned(N))) causes compiler to issue a
warning if the field in a struct or union is not aligned to N:
typedef unsigned long long __u64
__attribute__((aligned(4),warn_if_not_aligned(8)));
struct foo
{
int i1;
int i2;
__u64 x;
};
__u64 is aligned to 4 bytes. But inside struct foo, __u64 should be
aligned at 8 bytes. It is used to define struct foo in such a way that
struct foo has the same layout and x has the same alignment when __u64
is aligned at either 4 or 8 bytes.
Since struct foo is normally aligned to 4 bytes, a warning will be issued:
warning: alignment 4 of 'struct foo' is less than 8
Align struct foo to 8 bytes:
struct foo
{
int i1;
int i2;
__u64 x;
} __attribute__((aligned(8)));
silences the warning. It also warns the field with misaligned offset:
struct foo
{
int i1;
int i2;
int i3;
__u64 x;
} __attribute__((aligned(8)));
warning: 'x' offset 12 in 'struct foo' isn't aligned to 8
This warning is controlled by -Wif-not-aligned and is enabled by default.
When -Wpacked-not-aligned is used, the same warning is also issued for
the field with explicitly specified alignment in a packed struct or union:
struct __attribute__ ((aligned (8))) S8 { char a[8]; };
struct __attribute__ ((packed)) S {
struct S8 s8;
};
warning: alignment 1 of 'struct S' is less than 8
This warning is disabled by default and enabled by -Wall.
