Here is how fpstate VSO changes the game:
If you are writing a Pin tool and need to access the floating-point registers of the running program, you would interact with the FPSTATE structure. The high-level process looks like this: fpstate vso
In system-level programming (C/C++), fpstate refers to the structure holding CPU floating-point registers. If you are developing high-performance applications that interact with the kernel: Here is how fpstate VSO changes the game:
When a Linux process receives an asynchronous signal, the kernel temporarily interrupts normal execution to invoke a signal handler. Before jumping to user space code, the kernel builds a on the user's stack. fpstate vso
