URL: https://github.com/llvm/llvm-project/commit/80b108f404fc9e88889df7247f6ae9697083cbda DIFF: https://github.com/llvm/llvm-project/commit/80b108f404fc9e88889df7247f6ae9697083cbda.diff LOG: [lldb] [Process/NetBSD] Fix reading FIP/FDP registers Fix reading FIP/FDP registers to correctly return segment and offset parts. On amd64, this roughly matches the Linux behavior of splitting the 64-bit FIP/FDP into two halves, and putting the higher 32 bits into f*seg and lower into f*off. Well, actually we use only 16 bits of higher half but the CPUs do not seem to handle more than that anyway.
