SVE needs a way of broadcasting a scalar to a variable-length vector.
This patch adds VEC_DUPLICATE_EXPR for when CONSTRUCTOR would be used
for fixed-length vectors; this is the tree equivalent of the existing
rtl code VEC_DUPLICATE.
The patch also adds a vec_duplicate_optab to go with VEC_DUPLICATE_EXPR.

This patch adds a new "poly_int" class to represent polynomial integers
of the form:
C0 + C1*X1 + C2*X2 ... + Cn*Xn
It also adds poly_int-based typedefs for offsets and sizes of various
precisions. In these typedefs, the Ci coefficients are compile-time
constants and the Xi indeterminates are run-time invariants. The number
of coefficients is controlled by the target and is initially 1 for all
ports.
Most routines can handle general coefficient counts, but for now a few
are specific to one or two coefficients. Support for other coefficient
counts can be added when needed.
The patch also adds a new macro, IN_TARGET_CODE, that can be
set to indicate that a TU contains target-specific rather than
target-independent code. When this macro is set and the number of
coefficients is 1, the poly-int.h classes define a conversion operator
to a constant. This allows most existing target code to work without
modification. The main exceptions are:
- values passed through ..., which need an explicit conversion to a
constant
- ?: expression in which one arm ends up being a polynomial and the
other remains a constant. In these cases it would be valid to convert
the constant to a polynomial and the polynomial to a constant, so a
cast is needed to break the ambiguity.
The patch also adds a new target hook to return the estimated
value of a polynomial for costing purposes.
The patch also adds operator<< on wide_ints (it was already defined
for offset_int and widest_int). I think this was originally excluded
because >> is ambiguous for wide_int, but << is useful for converting
bytes to bits, etc., so is worth defining on its own. The patch also
adds operator% and operator/ for offset_int and widest_int, since those
types are always signed. These changes allow the poly_int interface to
be more predictable.
I'd originally tried adding the tests as selftests, but that ended up
bloating cc1 by at least a third. It also took a while to build them
at -O2. The patch therefore uses plugin tests instead, where we can
force the tests to be built at -O0. They still run in negligible time
when built that way.

This patch completes the infrastructure for the introduction of
statement frontiers in C-family languages.
It brings in all the code remaining code needed to introduce and
transform begin stmt trees, gimple stmts, insns and notes, and
ultimately use them to generate the is_stmt column in DWARF2+ line
number tables/programs, however none of it is activated: the option
that would do so will be introduced in a subsequent patch.
This patch depends on an earlier patch with not-quite-boilerplate
changes towards SFN.

This patch uses a simple compression scheme to represent the contents
of a VECTOR_CST using its leading elements. There are three formats:
1) a repeating sequence of N values. This is encoded using the first
N elements.
2) a "foreground" sequence of N values inserted at the beginning of
a "background" repeating sequence of N values, such as:
{ 1, 2, 0, 0, 0, 0, ... }. This is encoded using the first 2*N
elements.
2) a "foreground" sequence of N values inserted at the beginning of
a "background" repeating sequence of N interleaved linear series,
such as: { 0, 0, 8, 10, 9, 11, 10, 12, ... }. This is encoded
using the first 3*N elements. In practice the foreground values
are often part of the same series as the background values,
such as: { 1, 11, 2, 12, 3, 13, ... }.
This reduces the amount of work involved in processing simple
vector constants and means that the encoding extends naturally
to variable-length vectors.

ISO C17 won't go to ballot until December, meaning publication of the
standard won't be until 2018, leaving ambiguity as to whether people
will end up referring to the standard as C17, as it's currently known
and which corresponds to the __STDC_VERSION__ value, or C18 based on
the publication date.
In case people end up referring to this standard as C18, this patch
adds corresponding option aliases -std=c18, -std=iso9899:2018,
-std=gnu18 so people can use those names based on publication date if
they wish. The "expected to be" explanations in help texts and the
manual can be removed as and when the standard is published, hopefully
before GCC 8 is out.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
gcc:
* doc/invoke.texi (-std=c17): Refer to 2018 expected publication
date of C17.

Almost all targets add an explict -fomit-frame-pointer in the target specific
options. Rather than doing this in a target-specific way, do this in the

the amount of target code.

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.
