ead8e4c081e5c4de4d508fc353f381457b058ca6 - Merge commit 382f70a877f0 from llvm-project (by Louis Dionne):

Fri, 07 Jun 2024 18:42:53 +0000

Merge commit 382f70a877f0 from llvm-project (by Louis Dionne): [libc++][NFC] Rewrite function call on two lines for clarity (#79141) Previously, there was a ternary conditional with a less-than comparison appearing inside a template argument, which was really confusing because of the <...> of the function template. This patch rewrites the same statement on two lines for clarity.Merge commit d129ea8d2fa3 from llvm-project (by Vitaly Buka): [libcxx] Align `__recommend() + 1` by __endian_factor (#90292) This is detected by asan after #83774 Allocation size will be divided by `__endian_factor` before storing. If it's not aligned, we will not be able to recover allocation size to pass into `__alloc_traits::deallocate`. we have code like this ``` auto __allocation = std::__allocate_at_least(__alloc(), __recommend(__sz) + 1); __p = __allocation.ptr; __set_long_cap(__allocation.count); void __set_long_cap(size_type __s) _NOEXCEPT { __r_.first().__l.__cap_ = __s / __endian_factor; __r_.first().__l.__is_long_ = true; } size_type __get_long_cap() const _NOEXCEPT { return __r_.first().__l.__cap_ * __endian_factor; } inline ~basic_string() { __annotate_delete(); if (__is_long()) __alloc_traits::deallocate(__alloc(), __get_long_pointer(), __get_long_cap()); } ``` 1. __recommend() -> even size 2. `std::__allocate_at_least(__alloc(), __recommend(__sz) + 1)` - > not even size 3. ` __set_long_cap() `- > lose one bit of size for __endian_factor == 2 (see `/ __endian_factor`) 4. `__alloc_traits::deallocate(__alloc(), __get_long_pointer(), __get_long_cap())` -> uses even size (see `__get_long_cap`)This should fix incorrect deallocation sizes for some instances ofstd::string. Memory profiling or debugging tools like AddressSanitizer,LeakSanitizer or TCMalloc could then complain about the the size passedto a deallocation not matching the size originally passed to theallocation.Reported by: Aliaksei Kandratsenka PR: 279560MFC after: 3 days List of files: /src/contrib/llvm-project/libcxx/include/string
