call of the virtual function and do the inline. This is especially valuable for evaluation of expression trees. In impala , an expression consists of a tree of operations and functions, such as 2 . Each expression that appears in the tree is implemented with a function that overrides the base class of the expression, and the base class invokes the individual sub-expressions recursively. Many expression functions are very simple, such as the addition of two numbers, so . By removing virtual f

Xcode 7 Bitcode workflow and Security Evaluation
With the release of Xcode 7, Apple added a new feature Bitcode [1] For Xcode:
New features often mean new attack surfaces. This article first introduces Bitcode and Bitcode-related workflows. After familiarizing yourself with the Bitcode workflow, we will evaluate Bitcode-related attacks, finally, the test methods and current test results for each attack are introduced.
What is Bitcode
Simply put, Bitcode is a binary representation of a LLVM-

, the boundary scan (shift) Register units on the chip input/output pins can be connected to each other to form a boundary-scan chain around the chip ). The boundary scan chain can be input and output in serial mode. Through corresponding clock signals and control signals, you can conveniently observe and control the chips in the debugging state.
1. Test the access port tap
The test access port (TAP) is a common port used to access all data registers (DR) and command registers (

In addition, the boundary Scan (shift) register units on the chip input/output pins can be connected to each other, forming a boundary scan chain (Boundary-scanchain) around the chip. The boundary scan chain can be serially input and output, through the corresponding clock signal and control signal, it can easily observe and control the chip in the debugging stat

Another example:why do an expensive multiply operation:

the data. Pointers to these two vectors are generally written as "pr" (pointer to real data, pointer to real data) and "pi" (pointer to imaginary data, pointer to virtual data) ". If the pi of a matrix is null, it indicates that it is a real dual-precision matrix.

The storage format of sparse matrix in MATLAB is different. Like a double-precision matrix, it has the pr and pi parameters, and it also has three additional parameters: nzmax,

When loading a page, you can determine whether the R value is the same as the session ["RND"] value, if the data is the same, the submitted data will be processed. Otherwise, it will be regarded as "refresh" or "back", and a random code will be sent to session ["RND"] again.
