If a vDSO routine triggers vector-based optimizations (such as a compiler using AVX registers for an inlined memory copy), it must do so without corrupting the broader application's fpstate .

Tracing memory leaks and register corruption in highly concurrent, multithreaded applications. If a vDSO routine triggers vector-based optimizations (such
Before diving into the FPSTATE structure, it is crucial to understand the environment in which it exists. Dynamic Binary Instrumentation is a technique that allows developers to insert custom code into a running executable without modifying its source code or binaries. Tools like Intel Pin, DynamoRIO, and Valgrind operate by dynamically rewriting the binary code as it executes, intercepting instructions, and providing a powerful API for analysis. Before diving into the FPSTATE structure, it is
is simply the data structure holding all these registers.
