Supporting variable register sizes for the ARM Scalable Vector Extension (SVE) in GDB

Sep 8, 2017



SVE for Aarch64 poses challenges for GDB due to the register size being unknown until runtime, with the added complexity that register sizes may change during runtime. After a brief introduction to SVE, this talk will show how variable register sizes will be supported in GDB. In addition, we’ll touch on other interface changes such as Linux ptrace and DWARF support.
