I know the rmvnorm command is to be used but may be I am failing to properly assign the covariance matrix. Any help will be greatly appreciated thanks. M. R. Ahmad

...absd/hadd and sad are compatible with the discussions going on in other threads, for example my thread about min and max. Given that those two intrinsics are fairly trivial to match , I don't see the need to have two different canonical forms.

Hi Ahmad, If the Makefile contains only this command, then it is not worth spending time on GoldPlugin. If you are building a large project, then it will be simpler to use GoldPlugin. The steps you are using seem right. You can possibly combine the last two steps (3&4) using only 1 clang command....

...r. The code that you mentioned, seems to generate the IR. You mean I should reuse the code to extract and output the register names in a file. Next, I should postprocess the file in my own pass?

...so much for your response. You suggested approach is what I am right now using. However, it seems that the overhead is a little bit high because we are introducing two more instructions. I was wondering if there was a cheaper way to do it.

...#39;foo' user defined function? If there is no such utility function then I am thinking to do this in the following way: bool testFoo(CallInst *CI) { Function *Callee = CI->getCalledFunction(); if (Callee->getName() == "foo") return true; return false; } Thanks.

Hi Ahmad, Yes, merging works good. However, my problem is like this - I have a C library which consists of 1000's of functions spread through various files. The functions do not have dependency amoung each other. I want to link only relavant files( files which have functions called from my application...
