I guess Eric means full program optimization/cross module optimization using MIR. This is in theory workable in full LTO style, but not in ThinLTO style which works on summary data. As we have discussed, eliminating monolithic style optimization is the key design goal. This was also briefly discussed in one of the previous replies I sent. There are other benefits of doing this in linker such

Some more information about the relaxation pass whose effectiveness and convergence guarantees were listed as a concern: TLDR; Our relaxation pass is similar to what LLVM’s MCAssembler does but with a caveat for efficiency. Our experimental results show it is efficient and convergence is guaranteed. Our relaxation pass is very similar to what MCAssembler does as it needs to solve the same

We would also like to clarify on the misconceptions around CFI Instructions: There are two things that need to be clarified here: 1) Extra CFI FDE entries for basic blocks does not mean more dynamic instructions are executed. In fact, they do not increase at all. Krys talked about this earlier. 2) We do deduplication of common static CFI instructions in the FDE and move it to the CIE . Hence,

Hi, I want to get all the d-u pairs exercised at run-time. I am doing two things for this. I am useing the d-u iterator to instrument all uses. I also want to get an address trace. What are the instructions I should insttrument. Is load and store sufficient. Also, how do I go abt doing this ? Thanks -Sriraman.

Hi, i ran the insert-function-profiling pass on my bytecode and when i jit it, i get ' cant resolve 'llvm_start_func_profiling'. How do I link the "instrument" library. ? Thanks -Sriraman.

We are going to be at the llvm-dev meeting the next two days. We will get back to you after that.

Thanks Chris. Yes that was what I was looking for. -Sriraman.

Hi, New to LLVM and I want to try some sample programs and build on them. Any pointers to where I can find small projects ? Thanks.

You can also see the resulting module by using -disable-verify: $ opt -yourpass -disable-verify < file.bc | llvm-dis You may see what the problem is by looking at the LLVM assembly. -- Misha Brukman ::
