data address register

基本解釋

The dar (Data Address Register) contains the address that the processor tried to access, which then caused a page fault.
dar（數(shù)據(jù)地址寄存器）包含處理器嘗試訪問(wèn)的地址，這一行為將引發(fā)頁(yè)面錯(cuò)誤。
In the case of SIGILL, the DAR might not provide useful data, because this register is used to store the fault address in the case of SIGSEGV.
在 SIGILL 的情況中，DAR 可能不會(huì)提供任何有用的數(shù)據(jù)，因?yàn)檫@個(gè)寄存器在 SIGSEGV 的情況中就被用來(lái)存放故障地址。
Important registers to look for when debugging through signals are the GPRs, instruction pointer (NIP), machine state register (MSR), trap, data address register (DAR), and so on.
在調(diào)試信號(hào)時(shí)，需要查看的一些重要寄存器包括 GPR、指令指針 (NIP)、機(jī)器狀態(tài)寄存器 (MSR)、Trap、數(shù)據(jù)地址寄存器 (DAR) 等等。
