Add -std=c18 etc. option aliases.
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.

Use compare-debug for bootstrap-debug-lean to ignore != DW_AT_producer
Unlike bootstrap-debug, bootstrap-debug-lean used to pass compare using
the traditional compare command, because it compiled both stage2 and
stage3 with options that used to generate identical output
(-fcompare-debug= in stage2 vs -fcompare-debug in stage3).
Since we started adding relevant command-line flags to DW_AT_producer,
this is no longer the case, and stages 2 and 3 object files that differ
in nothing but the DW_AT_producer strings.
-fcompare-debug is short for -fcompare-debug=-gtoggle, so stage3
compiles twice, once with the normal options, once with toggled -g, to
then compare the temporary final dumps. When enabled, both compilations
get from the driver an additional -frandom-seed flag (if none is given
explicitly).
-fcompare-debug= is short for -fno-compare-debug, disabling the second
compilation.
The difference between the DW_AT_producer lines are the different
-fcompare-debug flags, and the presence of the -frandom-seed flag in the
stage3 compilation.
It is easy and sensible enough to filter the -fcompare-debug flags out
of the DW_AT_producer string. This option should never affect the
compilation output, it just determines whether or not to perform an
additional compilation that should produce the same executable output.
However, dropping -frandom-seed is not quite correct, in that it might
have other consequences on the compilation. So, it makes little sense
to make the effort to drop it when it's implicit; for those comparing
compiler output differences, it might even hint at what causes, and
could fix, difficult to explain differences, namely, explicitly
supplying -frandom-seed options.
They don't seem to matter for compiler bootstraps, though, at least
for now, so we can safely refrain from issuing -frandom-seed (or maybe
we already issue it where needed :-), and then, for
bootstrap-debug-lean, use the compare-debug script, that strips out
debug information before comparing the object files.

Joseph Myers [Wed, 15 Nov 2017 01:53:45 +0000 (01:53 +0000)]
Add __builtin_tgmath for better tgmath.h implementation (bug 81156).
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.
