[LLVMdev] Get the loop trip count variable
Hello Andreas,
Thanks! But I could not find -insert-optimal-edge-instrumenation pass
from "opt -help". Did you mean -insert-edge-profiling?
Cheers,

[LLVMdev] Get the loop trip count variable
Hello,
I am wondering whether I can get the variable name of loop trip count in LLVM?
For example,
int NUM;
NUM=atoi(argv[i]);
for (int i=0; i<NUM; i++)
{
...
}
How can I get the corresponding variable name for "NUM"? Then, I can
instrument something in the source code to record the loop trip count
for a given input data set.
BasicBlock* b = L->getHeader();
returns the basicblock of the loop header, but I don't know how to
extract "NUM" from basicblock b.

Using DTrace to monitor productions systems
Hi,
we are developing and operating an very critical application in the financial sector. Now our customer wants us to report performance data (roundtrip times of the messages routed).
My idea is using dtrace to measure the times with the pid provider catching the timestamps on entry of the in and out functions of the processes.
Now my questions ;-):
1) Is this an appropriate method to monitor
