2024-09-27libstdc++: Fix more pedwarns in headers for C++98Jonathan Wakely1-0/+3
Some tests e.g. 17_intro/headers/c++1998/all_pedantic_errors.cc FAIL with GLIBCXX_TESTSUITE_STDS=98 due to numerous C++11 extensions still in use in the library headers. The recent changes to not make them system headers means we get warnings now. This change adds more diagnostic pragmas to suppress those warnings. libstdc++-v3/ChangeLog: * include/bits/istream.tcc: Add diagnostic pragmas around uses of long long and extern template. * include/bits/locale_facets.h: Likewise. * include/bits/locale_facets.tcc: Likewise. * include/bits/locale_facets_nonio.tcc: Likewise. * include/bits/ostream.tcc: Likewise. * include/bits/stl_algobase.h: Likewise. * include/c_global/cstdlib: Likewise. * include/ext/pb_ds/detail/resize_policy/hash_prime_size_policy_imp.hpp: Likewise. * include/ext/pointer.h: Likewise. * include/ext/stdio_sync_filebuf.h: Likewise. * include/std/istream: Likewise. * include/std/ostream: Likewise. * include/tr1/cmath: Likewise. * include/tr1/type_traits: Likewise. * include/tr1/functional_hash.h: Likewise.

2024-09-25libstdc++: #ifdef out #pragma GCC system_headerJason Merrill1-0/+2
In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build flags to help catch problems in the library. This patch takes a different approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is defined. As a result, the testsuites will treat them as non-system-headers to get better warning coverage during regression testing of both gcc and libstdc++, not just when building the library. My rationale for the #ifdef instead of just removing the #pragma is the three G++ tests that want to test libstdc++ system header behavior, so we need a way to select it. This doesn't affect installed libraries, as they get their system-header status from the lookup path. But testsuite_flags --build-includes gives -I directives rather than -isystem. This patch doesn't change the headers in config/ because I'm not compiling with most of them, so won't see any warnings that need fixing. Adjusting them could happen later, or we can not bother. libstdc++-v3/ChangeLog: * acinclude.m4 (WARN_FLAGS): Remove -Wsystem-headers. * configure: Regenerate. * include/bits/algorithmfwd.h: #ifdef

2022-11-01libstdc++-v3: Some std::*float*_t charconv and i/ostream overloadsJakub Jelinek1-0/+88
The following patch adds the easy part of <charconv>, <istream> and <ostream> changes for extended floats. In particular, for the first one only overloads where the _Float* has the same format as float/double/long double and for the latter two everything but the _GLIBCXX_HAVE_FLOAT128_MATH case. For charconv, I'm not really familiar with it, I'm pretty sure we need new libstdc++.so.6 side implementation of from_chars for {,b}float16_t and for to_chars not really sure but for unspecified precision if it should emit minimum characters that to_chars then can unambiguously parse, I think it is less than in the float case. For float128_t {to,from}_chars I think we even have it on the library side already, just ifdefed for powerpc64le only. For i/o stream operator<</>>, not sure what is better, if not providing anything at all, or doing what we in the end do if user doesn't override the virtual functions, or use {to,from}_chars under the hood, something else? Besides this, the patch adds some further missed // { dg-options "-std=gnu++2b" } spots, I've also noticed I got the formatting wrong in some testcases by not using spaces around VERIFY conditions and elsewhere by having space before ( for calls. The testsuite coverage is limited, I've added test for from_chars because it was easy to port, but not really sure what to do about to_chars, it has for float/double huge testcases which would be excessive to repeat. And for i/ostream not really sure what exactly is worth testing. 2022-11-01 Jakub Jelinek <jakub@redhat.com> * include/std/charconv (from_chars, to_chars): Add _Float{32,64,128} overloads for cases where those types match {float,double,long double}. * include/std/istream (basic_istream::operator>>): Add _Float{16,32,64,128} and __gnu_cxx::__bfloat16_t overloads. * include/std/ostream (basic_ostream::operator<<): Add _Float{16,32,64,128} and __gnu_cxx::__bfloat16_t overloads. * testsuite/20_util/from_chars/8.cc: New test. * testsuite/26_numerics/headers/cmath/nextafter_c++23.cc (test): Formatting fixes. * testsuite/26_numerics/headers/cmath/functions_std_c++23.cc: Add dg-options "-std=gnu++2b".

2022-07-12libstdc++: Check for EOF if extraction avoids buffer overflow [PR106248]Jonathan Wakely1-5/+26
In r11-2581-g17abcc77341584 (for LWG 2499) I added overflow checks to the pre-C++20 operator>>(istream&, char*) overload. Those checks can cause extraction to stop after filling the buffer, where previously it would have tried to extract another character and stopped at EOF. When that happens we no longer set eofbit in the stream state, which is consistent with the behaviour of the new C++20 overload, but is an observable and unexpected change in the C++17 behaviour. What makes it worse is that the behaviour change is dependent on optimization, because __builtin_object_size is used to detect the buffer size and that only works when optimizing. To avoid the unexpected and optimization-dependent change in behaviour, set eofbit manually if we stopped extracting because of the buffer size check, but had reached EOF anyway. If the stream's rdstate() != goodbit or width() is non-zero and smaller than the buffer, there's nothing to do. Otherwise, we filled the buffer and need to check for EOF, and maybe set eofbit. The new check is guarded by #ifdef __OPTIMIZE__ because otherwise __builtin_object_size is useless. There's no point compiling and emitting dead code that can't be eliminated because we're not optimizing. We could add extra checks that the next character in the buffer is not whitespace, to detect the case where we stopped early and prevented a buffer overflow that would have happened otherwise. That would allow us to assert or set badbit in the stream state when undefined behaviour was prevented. However, those extra checks would increase the size of the function, potentially reducing the likelihood of it being inlined, and so making the buffer size detection less reliable. It seems preferable to prevent UB and silently truncate, rather than miss the UB and allow the overflow to happen. libstdc++-v3/ChangeLog: PR libstdc++/106248 * include/std/istream [C++17] (operator>>(istream&, char*)): Set eofbit if we stopped extracting at EOF. * testsuite/27_io/basic_istream/extractors_character/char/pr106248.cc: New test. * testsuite/27_io/basic_istream/extractors_character/wchar_t/pr106248.cc: New test.

2020-08-06libstdc++: Adjust overflow prevention to operator>>Jonathan Wakely1-7/+19
This adjusts the overflow prevention added to operator>> so that we can distinguish "unknown size" from "zero size", and avoid writing anything at all in to zero sized buffers. This also removes the incorrect comment saying extraction stops at a null byte. libstdc++-v3/ChangeLog: * include/std/istream (operator>>(istream&, char*)): Add attributes to get warnings for pointers that are null or known to point to the end of a buffer. Request upper bound from __builtin_object_size check and handle zero-sized buffer case. (operator>>(istream&, signed char)) (operator>>(istream&, unsigned char*)): Add attributes. * testsuite/27_io/basic_istream/extractors_character/char/overflow.cc: Check extracting into the middle of a buffer. * testsuite/27_io/basic_istream/extractors_character/wchar_t/overflow.cc: New test.
2020-08-05libstdc++: Replace operator>>(istream&, char*) [LWG 2499]Jonathan Wakely1-18/+51
P0487R1 resolved LWG 2499 for C++20 by removing the operator>> overloads that have high risk of buffer overflows. They were replaced by equivalents that only accept a reference to an array, and so can guarantee not to write past the end of the array. In order to support both the old and new functionality, this patch introduces a new overloaded __istream_extract function which takes a maximum length. The new operator>> overloads use the array size as the maximum length. The old overloads now use __builtin_object_size to determine the available buffer size if available (which requires -O2) or use numeric_limits<streamsize>::max()/sizeof(char_type) otherwise. This is a change in behaviour, as the old overloads previously always used numeric_limits<streamsize>::max(), without considering sizeof(char_type) and without attempting to prevent overflows. Because they now do little more than call __istream_extract, the old operator>> overloads are very small inline functions. This means there is no advantage to explicitly instantiating them in the library (in fact that would prevent the __builtin_object_size checks from ever working). As a result, the explicit instantiation declarations can be removed from the header. The explicit instantiation definitions are still needed, for backwards compatibility with existing code that expects to link to the definitions in the library. While working on this change I noticed that src/c++11/istream-inst.cc has the following explicit instantiation definition: template istream& operator>>(istream&, char*); This had no effect (and so should not have been present in that file), because there was an explicit specialization declared in <istream> and defined in src/++98/istream.cc. However, this change removes the explicit specialization, and now the explicit instantiation definition is necessary to ensure the symbol gets defined in the library. libstdc++-v3/ChangeLog: * config/abi/pre/gnu.ver (GLIBCXX_3.4.29): Export new symbols. * include/bits/istream.tcc (__istream_extract): New function template implementing both of operator>>(istream&, char*) and operator>>(istream&, char(&)[N]). Add explicit instantiation declaration for it. Remove explicit instantiation declarations for old function templates. * include/std/istream (__istream_extract): Declare. (operator>>(basic_istream<C,T>&, C*)): Define inline and simply call __istream_extract. (operator>>(basic_istream<char,T>&, signed char*)): Likewise.

(operator>>(basic_istream<char,T>&, unsigned char(&)[N])): Likewise. * include/std/streambuf (basic_streambuf): Declare char overload of __istream_extract as a friend. * src/c++11/istream-inst.cc: Add explicit instantiation definition for wchar_t overload of __istream_extract. Remove explicit instantiation definitions of old operator>> overloads for versioned-namespace build. * src/c++98/istream.cc (operator>>(istream&, char*)): Replace with __istream_extract(istream&, char*, streamsize). * testsuite/27_io/basic_istream/extractors_character/char/3.cc: Do not use variable-length array. * testsuite/27_io/basic_istream/extractors_character/char/4.cc: Do not run test for C++20. * testsuite/27_io/basic_istream/extractors_character/char/9555-ic.cc: Do not test writing to pointers for C++20. * testsuite/27_io/basic_istream/extractors_character/char/9826.cc: Use array instead of pointer. * testsuite/27_io/basic_istream/extractors_character/wchar_t/3.cc: Do not use variable-length array. * testsuite/27_io/basic_istream/extractors_character/wchar_t/4.cc: Do not run test for C++20. * testsuite/27_io/basic_istream/extractors_character/wchar_t/9555-ic.cc: Do not test writing to pointers for C++20. * testsuite/27_io/basic_istream/extractors_character/char/lwg2499.cc: New test. * testsuite/27_io/basic_istream/extractors_character/char/lwg2499_neg.cc: New test. * testsuite/27_io/basic_istream/extractors_character/char/overflow.cc: New test. * testsuite/27_io/basic_istream/extractors_character/wchar_t/lwg2499.cc: New test. * testsuite/27_io/basic_istream/extractors_character/wchar_t/lwg2499_neg.cc: New test.
