| Use of SHR and SHL instructions |
| 24 Apr 18 17:27:12 |
From: samakshkaushik@nospicedham.gmail.com What is the purpose of using SHR and SHL Instructions. For example I have the following instructions. 0x0804854c <+12>: mov eax,0x0 0x08048551 <+17>: add eax,0xf 0x08048554 <+20>: add eax,0xf 0x08048557 <+23>: shr eax,0x4 0x0804855a <+26>: shl eax,0x4 => 0x0804855d <+29>: sub esp,eax Why was shr and shl used? I am debugging using GDB and I am not using any switch for optimization. --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
