[Lldb-commits] [lldb] [PPC64][Linux] Watchpoint configuration for PPC64 (PR #185192)

[Dhruv Srivastava via lldb-commits]

https://github.com/DhruvSrivastavaX created https://github.com/llvm/llvm-project/pull/185192

On PPC64, SIGTRAP is delivered before the triggering instruction completes. The previous implementation did not correctly tell this to qSupported response causing the SingleStep to not happen on Linux for PPC64, at the execution being stuck at the store instruction.
This patch corrects this.
