* Containers: add max_size()Giuseppe D'Angelo2024-02-271-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One more method for STL compatibility. This one is particularly subtle as it's required by the `reservable-container` concept: https://eel.is/c++draft/ranges#range.utility.conv.general-3 Without this concept, ranges::to won't reserve() before copying the elements (out of a sized range which isn't a common_range). Implementation notes: there were already a couple of constants denoting the maximum QByteArray and QString size. Centralize that implementation in QTypedArrayData, so that QList can use it too. The maximum allocation size (private constant) needs a even more central place so that even QVLA can use it. Lacking anything better, I've put it in qcontainerfwd.h. Since our containers aren't allocator-aware, I can make max_size() a static member, and replace the existing constants throughout the rest of qtbase. (I can't kill them yet as they're used by other submodules.) [ChangeLog][QtCore][QList] Added max_size(). [ChangeLog][QtCore][QString] Added max_size(). [ChangeLog][QtCore][QByteArray] Added max_size(). [ChangeLog][QtCore][QVarLengthArray] Added max_size().

* QArrayData: move AlignedQArrayData to the public headerThiago Macieira2023-12-111-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | This allows us to use it in QTypedArrayData<T>::AlignmentDummy, which is used in __builtin_assume_aligned() as a hint to the compiler. This increases the value we were passing as the compiler hint from 4 to 8 on 32-bit platforms and from 8 to 16 on 64-bit platforms. We actually do align to a bit higher than even that, but that's not an ABI guarantee we're making. However, it looks like GCC on 32-bit platforms is buggy, so we work around it. Commit r240248 ("Make max_align_t respect _Float128.", 63012d9a57edc950c5f30242d1e19318b5708060 in Git) increased std::max_align_t to 16 bytes on all platforms, saying "Such an increase is of course an ABI change" and "I think glibc malloc alignment should also increase to 16-byte 32-bit x86", but such a change to glibc was never implemented. Moreover, there are systems that don't use glibc, such as when using GCC on other OSes. This is not a change in Qt behavior anywhere. i386 does not (usually) do alignment checks, so most code wouldn't notice this at all.

* QArrayData: add allocate1 and allocate2 for 1- and 2-byte typesThiago Macieira2023-12-111-5/+27
| | | | | | | | | | | | | | | | This makes the two most-often used QTypedArrayData::allocate() -- the ones for char (for QByteArray) and char16_t (for QString) -- go to specialized versions, which have much simpler code. After all, multiplications by 1 are quite trivial. I didn't check whether an LTO compiler was const-propagating the sizes in inlined calls from qstring.cpp and qbytearray.cpp. But not everyone uses LTO, so this benefits everyone, in a very hot path, for minimal cost.

What we really want is to check for a literal type (so that the array payload can be built entirely at compile time, and put in .rodata). So, amend the check. Also, make the dummy array constexpr, to be sure that we are indeed building the payload using constexpr constructors. That would make the first check redundant, but the fact that we're still using a macro for constexpr makes me think that not all compilers support it, so I'm leaving the first check in...
