Integrate BLCR to GDB


Hi,
  If my understanding is correct, current gdb checkpoint/restart is using
fork() and does not support multi-threading. 

  I am interested to know if  someone has done some work to integrate BLCR
(Berkely Lab Checkpoint/Restart ,
https://ftg.lbl.gov/CheckpointRestart/CheckpointRestart.shtml) into gdb? 

  As a standalone, BLCR is quite helpful in certain debugging scenarios. But
it is a bit hard to use with gdb , i.e. breakpoints can not be saved and
restart is not convienent to stop at certain point etc. 

  BLCR's limitation is it is only for Linux x86 and x86_64. It also needs to
load kernel modules which may or may not be an issue. It is not targeting
debugging but rather process management/fault tolerance. 
 

  Thanks,
  Zhiyong
