Arm’s Scalable Vector Extension (SVE) has introduced a new challenge to the debugger world where vector register size is unknown until run time and also can change during execution. Arm has been innovating in the past year or so to live up to the challenge of SVE in GDB. Linaro has begun to do the same for the LLDB debugger in the LLVM toolchain world. In this talk we will briefly introduce SVE and its impact on debugger’s register access design. Moreover, we will discuss SVE support in LLDB, will give an overview of the whole effort and will provide updates about completed, in progress and completed tasks.
