Assembly, System Calls, and Hardware in C++ - David Sankel - CppNow 2023

​ --- Under the Hood: Assembly, System Calls, and Hardware in C - David Sankel - CppNow 2023 Slides: --- When programming day to day in C , we frequently take for granted the hardware instructions we're creating. You may have heard that system calls are expensive, but do you know what a system call actually does? You may have heard of calling conventions, but do you know what that looks like in practice? All too often we take these and other aspects of our systems as a kind of uninvestigated lore. In this talk we're taking a deep dive into how computers work when you strip off the veneer of C code. We'll cover assembly basics and delve into system calls, calling conventions, atomics, and other low-level aspects of computer hardware. Our primary focus will be x86-64/Linux, but we'll touch on Arm and other operating systems where relevant. --- David Sankel David Sankel is a Principal Scientist in Adobe's Software Technology Lab and an active member of the C Standardization Committee.
