In the meanwhile i used iceext extension for sice.
It is not detected mostly even by Int1.

I tried Ur suggestion. works well.

One culd use a macro too:
MACRO a= "r eip eip-1; eb eip %1"

At the entry i have
PUSHFD
PUSHAD
CALL abcd
here reisters are saved.
and these should be restored to just before OEP jump.

so i looked for the register value loaction in data window and

set break on text then bpx / bpm at address. but it doesnot stop there.

Where am I going wrong
