This patch from Le-Chun Wu adds two new shadow warning flags for
C and C++:
-Wshadow=local which warns if a local variable shadows another local
variable or parameter,
-Wshadow=compatible-local which warns if a local variable shadows
another local variable or parameter whose type is compatible with
that of the shadowing variable.
It is already on the google/main branch (Google ref 39127) and was
previously submitted by Diego Novillo and reviewed on
http://codereview.appspot.com/4452058
I addressed the review comments and made the following changes:
- Add -Wshadow=global (the default alias for -Wshadow).
- Make the documented options -Wshadow=global, -Wshadow=local
and -Wshadow=compatible-local (with hidden undocumented aliases
-Wshadow-local and -Wshadow-compatible-local for compatibility).
- The -Wshadow=global, -Wshadow=local and -Wshadow=compatible-local
relationships are expressed in common.opt instead of in opts.c
and documented in invoke.texi.
- The "previous declaration" warnings were turned into notes and use
the (now) existing infrastructure instead of duplicating the warnings.
The testcases have been adjusted to expect the notes.
- The conditional change in name-lookup.c for non-locals (where we
don't want to change the warnings, but just check the global ones)
has been dropped.
- Use warning_at in c-decl.c (warn_if_shadowing).

The API for adding "insert text" fix-it hints was unclear
about exactly where the text should be inserted relative
to the given insertion point.
This patch clarifies things by renaming the pertinent methods from
richloc.add_fixit_insert
to
richloc.add_fixit_insert_before
and adding:
richloc.add_fixit_insert_after
The latter allows us to consolidate some failure-handling into
class rich_location, rather than having to have every such diagnostic
check for it.
The patch also adds a description of how fix-it hints work to the
comment for class rich_location within libcpp/include/line-map.h.

keywords e.g.:

‘struct’ keyword to refer to the type
foo_t *foo_ptr;
^~~~~
struct
However when using the (not yet in trunk) option
-fdiagnostics-generate-patch,
the generated patch is nonsensical:
-foo_t *foo_ptr;
+structfoo_t *foo_ptr;

Adding a fix-it hint to a diagnostic usually follows one of these
patterns:
(a) an insertion fix-its, with the insertion at the primary caret location
(b) a removals/replacements, affecting the range of the primary location
(other cases are possible, e.g. multiple fix-its, and affecting other
locations, but these are the common ones)
Given these common cases, this patch adds overloads of the rich_location
methods for adding fix-it hints, so that the location information can
be omitted if it matches that of the primary location within the
rich_location.
Similarly when adding "remove" and "replace" fix-it hints to a diagnostic,
it's tedious to have to extract the source_range from a location_t
(aka source_location). To make this more convenient, this patch
adds overload of the rich_location::add_fixit_remove/replace methods,
accepting a source_location directly.
The patch updates the various in-tree users of fix-it hints to use
the new simpler API where appropriate. I didn't touch the case where
there are multiple fix-its in one rich_location, as it seems better to
be more explicit about locations for this case (adding a pair of parens
in warn_logical_not_parentheses).
The above makes the gcc_rich_location::add_fixit_misspelled_id overload
taking a const char * rather redundant, so I eliminated it.

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).

This adds fix-it hints to c-format.c so that it can (sometimes) suggest
the format string the user should have used.
The patch adds selftests for the new code in c-format.c. These
selftests are thus lang-specific. This is the first time we've had
lang-specific selftests, and hence the patch also adds a langhook for
running them. (Note that currently the Makefile only invokes the
selftests for cc1).
