Using the Clang Integrated Assembler to Compile the Linux Kernel

Explore the challenges and potential solutions for using the Clang Integrated Assembler (IA) to compile the Linux Kernel in this 26-minute conference talk from the Linux Plumbers Conference. Learn about the powerful features of IA within the Clang toolchain, including its diagnostics, speed, and integration capabilities. Discover the current difficulties faced when utilizing IA with the Linux Kernel on ARM and x86 architectures. Delve into topics such as ambiguous inline assembly, mode switching, explicit registries, and stack pointer output. Gain insights into possible solutions for overcoming the obstacles that currently prevent the widespread use of IA in Linux Kernel compilation.
