2019-06-13Darwin, testsuite - Adjust two tests that fail on newer OS versions.Iain Sandoe3-2/+7
Newer OS versions (10.14+) do not provide some of the CRTs that are used for older ones (e.g. 10.5), and thus link tests that specify targeting such a revision fail. We retain the testing of the correct defined OS version number but switch to compile-only testing for these two tests. 2019-06-13 Iain Sandoe <iain@sandoe.co.uk> * gcc.dg/darwin-minversion-1.c: Use compile rather than link/run. * gcc.dg/darwin-minversion-2.c: Likewise.

2019-06-12[nvptx] Assert fork has at most one join in nvptx_find_parTom de Vries2-0/+6
With the test-case of PR90009 we run into a SIGSEGV in nvptx_neuter_pars, because par->join_insn and par->join_block are NULL. Detect this problem earlier, by adding an assert in nvptx_find_par that asserts that a fork cannot be paired with more than one join. Build and tested on x86_64 with nvptx accelerator enabled. 2019-06-12 Tom de Vries <tdevries@suse.de> PR tree-optimization/90009 * config/nvptx/nvptx.c (nvptx_find_par): Assert fork has at most join.

2019-06-12Replace std::to_string for integers with optimized versionJonathan Wakely9-75/+365
The std::to_chars functions from C++17 can be used to implement std::to_string with much better performance than calling snprintf. Only the __detail::__to_chars_len and __detail::__to_chars_10 functions are needed for to_string, because it always outputs base 10 representations. The return type of __detail::__to_chars_10 should not be declared before C++17, so the function body is extracted into a new function that can be reused by to_string and __detail::__to_chars_10. The existing tests for to_chars rely on to_string to check for correct answers. Now that they use the same code that doesn't actually ensure correctness, so add new tests for std::to_string that compare against printf output. * include/Makefile.am: Add new <bits/charconv.h> header. * include/Makefile.in: Regenerate. * include/bits/basic_string.h (to_string(int), to_string(unsigned)) (to_string(long), to_string(unsigned long), to_string(long long)) (to_string(unsigned long long)): Rewrite to use __to_chars_10_impl. * include/bits/charconv.h: New header. (__detail::__to_chars_len): Move here from <charconv>. (__detail::__to_chars_10_impl): New function extracted from __detail::__to_chars_10. * include/std/charconv (__cpp_lib_to_chars): Add, but comment out. (__to_chars_unsigned_type): New class template that reuses __make_unsigned_selector_base::__select to pick a type. (__unsigned_least_t): Redefine as __to_chars_unsigned_type<T>::type. (__detail::__to_chars_len): Move to new header. (__detail::__to_chars_10): Add inline specifier. Move code doing the output to __detail::__to_chars_10_impl and call that. * include/std/version (__cpp_lib_to_chars): Add, but comment out. * testsuite/21_strings/basic_string/numeric_conversions/char/ to_string.cc: Fix reference in comment.
