 [libc][test][stdbit] fix -Wimplicit-int-conversion (#126616) 2025-02-11T17:31:01+00:00 Nick Desaulniers ndesaulniers@google.com 2025-02-11T17:31:01+00:00 b8ba266820ca51216c98216369a4947a942ec21c When cross compiling the libc-stdbit-tests, the existing tests trigger numerous instances of -Wimplicit-int-conversion. The truncation of these implicit promotions is intentional.

[libc] Fix use of cpp::numeric_limits<...>::digits (#102674) 2024-08-09T20:09:23+00:00 Roland McGrath mcgrathr@google.com 2024-08-09T20:09:23+00:00 a21cf5663c3e757e98a396e47471af63bd4955b0 The previous change replaced INT_WIDTH with cpp::numberic_limits<int>::digits, but these don't have the same value. While INT_WIDTH == UINT_WIDTH, not so for ::digits, so use cpp::numberic_limits<unsigned int>::digits et al instead for the intended effects. Bug: https://issues.fuchsia.dev/358196552

 [libc] Use cpp::numeric_limits in preference to C23 <limits.h> macros (#102665) 2024-08-09T19:44:40+00:00 Roland McGrath mcgrathr@google.com 2024-08-09T19:44:40+00:00 2f6a879790d0496375bb9ab5351c9b61058473e8 This updates some code to consistently use cpp::numeric_limits, the src/__support polyfill for std::numeric_limits, rather than the C <limits.h> macros. This is in keeping with the general C++-oriented style in libc code, and also sidesteps issues about the new C23 *_WIDTH macros that the compiler-provided header does not define outside C23 mode.
