Hi, I am using acts_as_athenticated plugin for my rails application. That plugin is using "SHA1" algorithm to encrypt password & stroe it into database. Now in future suppose user requsted his password through email, hhow should I decrypt that password in my application & for sending it through mail? Please help me. I am trying this since last 2 days. But still not succeeded. Thanx in advance for ur help. Prash -- Poste...

...tes codes like this: 29 p1 = r2; 30 r5 = [p1]; 31 p1 = r2; 32 r6 = [p1 + 4]; 33 r5 = r6 + r5; 34 r6 = [p0 + -4]; 35 r5 *= r6; 36 p1 = r2; 37 r6 = [p1 + 8]; 38 p1 = r2; p1 and r2 are in different register classes. A p* register can be used for load/stroe values from memory while a r* register can not. As we can see, line 31, 36, 38 can be deleted. How can I configure llc to do this? Or do I have to write a custom pass to do this optimization? Any suggestion is welcome. Thanks, Huang -------------- next part -------------- An HTML attachment was...

...y using LLVM. Instead of inserting comparison code in the prologue of the function, I would like do the probe before arguments pushed. The segmentd stacks append a guarded page. This guard page will call the addmorestack function if the probe instructions touch this guarded page. Otherwise, it only stroe the return address in the bottom of the callee stack frame. In order to achieve this, for each function call, two instructions are needed to be inserted: LEA %EAX, callee_return_label MOV [ESP- callee_stack_frame_size - arguments_size], %EAX PUSH argn ... PUSH arg1 J...
