Hi,
I am 
just a new comer in GDB internals. I have a doubt regarding the necessity of 
SOFTWARE_SINGLE_STEP in the function resume() (file: infrun.c). My working 
platform is Sparc- Solaris 5.8 and going through the code of GDB 4.18. The 
question is :
 
The 
file procfs.c have the support for single step using the PRSTEP flag (function: 
proc_run_process() ). Then, is there any specific reason behind doing 
SOFTWARE_SINGLE_STEP rather than using the proc system support? Will there be 
any hidden side effect if I disabled SOFTWARE_SINGLE_STEP_P and use PRSTEP for 
single stepping?
 
Looking forward to an early response.  
Thanks 
in advance.
mahata.
