2ae52326 - [libc++] Towards a simpler extern template story in libc++

Tue, 08 Jun 2021 21:25:08 +0000

[libc++] Towards a simpler extern template story in libc++The flexibility around extern template instantiation declarations inlibc++ result in a very complicated model, especially when support forslightly different configurations (like the debug mode or assertionsin the dylib) are taken into account. That results in unexpected bugslike http://llvm.org/PR50534 (and there have been multiple similarbugs in the past, notably around the debug mode).This patch gets rid of the _LIBCPP_DISABLE_EXTERN_TEMPLATE knob, whichI don't think is fundamental. Indeed, the motivation for that knob was toavoid taking a dependency on the library, however that can be done betterby linking against the static library instead. And in fact, some parts ofthe headers will always depend on things defined in the library, whichdefeats the original goal of _LIBCPP_DISABLE_EXTERN_TEMPLATE.Differential Revision: https://reviews.llvm.org/D103960 List of files: /llvm-project-15.0.7/libcxx/include/sstream

385cc25a - [libc++] Ensure that all public C++ headers include <__assert>

Fri, 25 Mar 2022 16:55:36 +0000

[libc++] Ensure that all public C++ headers include <__assert>This patch changes the requirement for getting the declaration of theassertion handler from including <__assert> to including any publicC++ header of the library. Note that C compatibility headers areexcluded because we don't implement all the C headers ourselves --some of them are taken straight from the C library, like assert.h.It also adds a generated test to check it. Furthermore, this newgenerated test is designed in a way that will make it possible toreplace almost all the existing test-generation scripts with thissystem in upcoming patches.Differential Revision: https://reviews.llvm.org/D122506 List of files: /llvm-project-15.0.7/libcxx/include/sstream

[libc++] Remove some _LIBCPP_CXX03_LANG from iostreams headers.With the STL containers, I didn't enable move operations in C++03 modebecause that would change the overload resolution for things that todayare copy operations. With iostreams, though, the copy operations aren'tpresent at all, and so I see no problem with enabling move operationseven in (Clang's greatly extended) C++03 mode.Clang's C++03 mode does not support delegating constructors.Differential Revision: https://reviews.llvm.org/D104310 List of files: /llvm-project-15.0.7/libcxx/include/sstream

997d41cd - [libc++] Instantiate additional members in the dylib

Wed, 21 Oct 2020 15:11:45 +0000

[libc++] Instantiate additional members in the dylibThis commit adds new explicit instantiations for some classes in in the library. This is done after noticing that many programs that usestreams end up containing weak definitions of these classes, which has anegative impact on both code size and load times (due to the need toresolve weak symbols at load time). Note that we are just adding theadditional explicit instantiations for the `char` specializations, sincethe `wchar_t` specializations are not used as often, and as a result therewouldn't be a clear benefit.This change is not an ABI break, since we are just adding additionalsymbols.Differential Revision: https://reviews.llvm.org/D90677 List of files: /llvm-project-15.0.7/libcxx/include/sstream

57b08b09 - Update more file headers across all of the LLVM projects in the monorepo

Sat, 19 Jan 2019 10:56:40 +0000

Update more file headers across all of the LLVM projects in the monorepoto reflect the new license. These used slightly different spellings thatdefeated my regular expressions.We understand that people may be surprised that we're moving the headerentirely to discuss the new license. We checked this carefully with theFoundation's lawyer and we believe this is the correct approach.Essentially, all code in the project is now made available by the LLVMproject under our new license, so you will see that the license headersinclude that license only. Some of our contributors have contributedcode under our old license, and accordingly, we have retained a copy ofour old license notice in the top-level files in each project andrepository.llvm-svn: 351648 List of files: /llvm-project-15.0.7/libcxx/include/sstream

Tue, 19 Dec 2017 23:33:16 +0000

libcxx: Fix for basic_stringbuf::seekoff() after r320604.As a result of this change, the basic_stringbuf constructor thattakes a mode ends up leaving __hm_ set to 0, causing the comparison"__hm_ - __str_.data() < __noff" in seekoff() to succeed, which causedthe function to incorrectly return -1. The fix is to account for thepossibility of __hm_ being 0 when computing the distance from __hm_to the start of the string.Differential Revision: https://reviews.llvm.org/D41319llvm-svn: 321124 List of files: /llvm-project-15.0.7/libcxx/include/sstream

Wed, 13 Dec 2017 18:12:55 +0000

[libcxx] Fix basic_stringbuf constructorSummary:[libcxx] Fix basic_stringbuf constructorThe C++ Standard [stringbuf.cons]p1 defines the effects of the basic_stringbufconstructor that takes ios_base::openmode as follows: Effects: Constructs an object of class basic_stringbuf, initializing the base class with basic_streambuf(), and initializing mode with which. Postconditions: str() == "".The default constructor of basic_streambuf shall initialize all itspointer member objects to null pointers [streambuf.cons]p1.Currently libc++ calls "str(string_type());" in the aforementioned constructorsetting basic_streambuf's pointers to a non-null value.This patch removes the call (note that the postcondition str() == ""remains valid because __str_ is default-initialized) and adds a test checkingthat the basic_streambuf's pointers are null after construction.Thanks Mikhail Maltsev for the patch.Reviewers: EricWF, mclow.listsReviewed By: mclow.listsSubscribers: cfe-commitsDifferential Revision: https://reviews.llvm.org/D40707llvm-svn: 320604 List of files: /llvm-project-15.0.7/libcxx/include/sstream
