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.
