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

2023-05-31libstdc++: Stop using _GLIBCXX_USE_C99_MATH_TR1 in <cmath>Jonathan Wakely1-2/+2
Similar to the three commits r14-908, r14-909 and r14-910, the _GLIBCXX_USE_C99_MATH_TR1 macro is misleading when it is also used for <cmath>, not only for <tr1/cmath> headers. It is also wrong, because the configure checks for TR1 use -std=c++98 and a target might define the C99 features for C++11 but not for C++98. Add separate configure checks for the <math.h> functions using -std=c++11 for the checks. Use the new macro defined by those checks in the C++11-specific parts of <cmath>, and in <complex>, <random> etc. The check that defines _GLIBCXX_NO_C99_ROUNDING_FUNCS is only needed for the C++11 <cmath> checks, so remove that from GLIBCXX_CHECK_C99_TR1 and only do it for GLIBCXX_ENABLE_C99. libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_ENABLE_C99): Add checks for C99 math functions and define _GLIBCXX_USE_C99_MATH_FUNCS. Move checks for C99 rounding functions to here. (GLIBCXX_CHECK_C99_TR1): Remove checks for C99 rounding functions from here. * config.h.in: Regenerate. * configure: Regenerate. * include/bits/random.h: Use _GLIBCXX_USE_C99_MATH_FUNCS instead of _GLIBCXX_USE_C99_MATH_TR1. * include/bits/random.tcc: Likewise. * include/c_compatibility/math.h: Likewise. * include/c_global/cmath: Likewise. * include/ext/random: Likewise. * include/ext/random.tcc: Likewise. * include/std/complex: Likewise. * testsuite/20_util/from_chars/4.cc: Likewise. * testsuite/20_util/from_chars/8.cc: Likewise. * testsuite/26_numerics/complex/proj.cc: Likewise. * testsuite/26_numerics/headers/cmath/60401.cc: Likewise. * testsuite/26_numerics/headers/cmath/types_std_c++0x.cc: Likewise. * testsuite/lib/libstdc++.exp (check_v3_target_cstdint): Likewise. * testsuite/util/testsuite_random.h: Likewise.

Since r9-2028-g8ba7f29e3dd064 we've defined most of <cstdint> unconditionally, including uint_least32_t. This means that all of <random> can be defined unconditionally, which means that std::shuffle and std::ranges::shuffle can be too. libstdc++-v3/ChangeLog: * include/bits/algorithmfwd.h (shuffle): Do not depend on _GLIBCXX_USE_C99_STDINT_TR1. * include/bits/ranges_algo.h (shuffle): Likewise. * include/bits/stl_algo.h (shuffle): Likewise. * include/ext/random: Likewise. * include/ext/throw_allocator.h (random_condition): Likewise. * include/std/random: Likewise. * src/c++11/cow-string-inst.cc: Likewise. * src/c++11/random.cc: Likewise.

These overloads are not needed in C++20 as they can be synthesized by the compiler.

2022-10-04libstdc++: Refactor seed sequence constraints in <random>Jonathan Wakely1-3/+3

2019-08-09skip Cholesky decomposition in is>>n_mv_distAlexandre Oliva1-0/+15
normal_mv_distribution maintains the variance-covariance matrix param in Cholesky-decomposed form. Existing param_type constructors, when taking a full or lower-triangle varcov matrix, perform Cholesky decomposition to convert it to the internal representation. This internal representation is visible both in the varcov() result, and in the streamed-out representation of a normal_mv_distribution object. The problem is that when that representation is streamed back in, the read-back decomposed varcov matrix is used as a lower-triangle non-decomposed varcov matrix, and it undergoes Cholesky decomposition again. So, each cycle of stream-out/stream-in changes the varcov matrix to its "square root", instead of restoring the original params. This patch includes Corentin's changes that introduce verification in testsuite/ext/random/normal_mv_distribution/operators/serialize.cc and other similar tests that the object read back in compares equal to the written-out object: the modified tests pass only if (u == v). This patch also fixes the error exposed by his change, introducing an alternate private constructor for param_type, used only by operator>>. for libstdc++-v3/ChangeLog * include/ext/random (normal_mv_distribution::param_type::param_type): New private ctor taking a decomposed varcov matrix, for use by...

Using #include "..." to include a header in the same directory fails if the user compiles with -I-, so always use something like <bits/...> for internal headers. I haven't added tests for this, because dg-options adds options to the end, and the position of -I- matters (if it's at the end then the tests won't find any headers in the build tree, as they're specified by -I options earlier in the flags).
