2017-11-15Use compare-debug for bootstrap-debug-lean to ignore != DW_AT_producerAlexandre Oliva2-0/+6
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. for config/ChangeLog * bootstrap-debug-lean.mk (do-compare): Use the contrib/compare-debug script. for gcc/ChangeLog * dwarf2out.c (gen_producer_string): Discard OPT_fcompare_debug.

2017-11-15Add __builtin_tgmath for better tgmath.h implementation (bug 81156).Joseph Myers15-63/+1441
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.
