chars_format.h	[libc++][NFC] Replace _NOEXCEPT and _LIBCPP_CONSTEXPR macros with the keywords in C++11 code (#96387)	2 年前
from_chars_floating_point.h	Revert "[libc++] Introduce ABI sensitive areas to avoid requiring _LIBCPP_HIDE_FROM_ABI everywhere (#131156)" (#141756) This reverts commit c861fe8a71e64f3d2108c58147e7375cd9314521. Unfortunately, this use of hidden visibility attributes causes user-defined specializations of standard-library types to also be marked hidden by default, which is incorrect. See discussion thread on #131156. ...and also reverts the follow-up commits: Revert "[libc++] Add explicit ABI annotations to functions from the block runtime declared in <__functional/function.h> (#140592)" This reverts commit 3e4c9dc299c35155934688184319d391b298fff7. Revert "[libc++] Make ABI annotations explicit for windows-specific code (#140507)" This reverts commit f73287e623a6c2e4a3485832bc3e10860cd26eb5. Revert "[libc++][NFC] Replace a few "namespace std" with the correct macro (#140510)" This reverts commit 1d411f27c769a32cb22ce50b9dc4421e34fd40dd.	1 年前
from_chars_integral.h	[libc++] Remove is_signed<T> use from <limits> (#168334) numeric_limits already has an is_signed member. We can use that instead of using std::is_signed.	8 个月前
from_chars_result.h	[libc++] Remove a few incorrect _LIBCPP_EXPORTED_FROM_ABI annotations (#132602) This has two benefits: - It is less likely that the macro will be copy-pasted around when unnecessary - We can drop _LIBCPP_HIDE_FROM_ABI from any member functions once we are able to make _LIBCPP_HIDE_FROM_ABI the default within libc++	11 个月前
tables.h	Reapply "[libc++] Optimize num_put integral functions" (#131613) (#133572) This reverts commit d1156fcb56891fb1a426c3e8331a51d47f98a1b8. This patch fixes the reported incorrect formatting changes and adds tests for them. The performance should be unaffected, since there are no significant changes required to fix the bugs. Specifically, a > was changed to a >= to also add a + in the zero case, and we're checking for zero now before printing the octal and hexadecimal prefixes. Closes #131710	1 年前
to_chars.h	[libc++][charconv] Granularizes the header. Having the header granularized makes it possible to remove the dependency on this header in <format>. This <format> header gets included in more headers due to more usage of std::formatter in the library. This should reduce the number of transitive includes. Note formatting the new headers will be done in a followup patch. Reviewed By: #libc, ldionne Differential Revision: https://reviews.llvm.org/D145590	3 年前

traits.h	[libc++] Replace __libcpp_{ctz, clz} with __builtin_{ctzg, clzg} (#133920) __libcpp_{ctz, clz} were previously used as fallbacks for __builtin_{ctzg, clzg} to ensure compatibility with older compilers (Clang 18 and earlier), as __builtin_{ctzg, clzg} became available in Clang 19. Now that support for Clang 18 has been officially dropped in #130142, we can now safely replace all instances of __libcpp_{ctz, clz} with __count{l,r}_zero (which internally call __builtin_{ctzg, clzg} and eliminate the fallback logic. Closes #131179.	1 年前
