(3)当vector中的元素为指针的时候,拷贝的是指针本身,而不是指针指向的对象,此时释放掉指针对象的空间,那么vector中的元素就找不到地址,用valgrind会告诉说访问已经free的内存,但是不会出现内存泄露; ==14367== Invalid read of size1==14367== at0x3B7726CF1A: _IO_file_xsputn@@GLIBC_2.2.5(in/lib64/lib...

在small_vector improvements提交中,改为了申请新内存、放入新数据、迁移原有数据。理由是有可能emplace_back的数据是small_vector中的某一个数据的引用, 比如这次提交中加的ForwardingEmplaceInsideVector test,不过这属于corner case。 makeGuard 在Support -fno-exceptions in folly/small_vector.h提交里,使用makeGuard...

Dynamic alignment is an optimization the compiler can perform to improve alignment of memory references inside the loop. It involves peeling iterations from the vector loop into a scalar loop (which may, in turn, also be vectorized) before the vector loop so that the vector loop aligns with a...
This post will discuss how to print a vector in C++... Vectors are the dynamic, re-sizable implementation of array data structure in C++. The vector elements are stored in contiguous locations, which makes the element access easier, and hence we can prin
