Hello, I am curious to know if LLVM offers any passes to do interprocedural slicing, I need to eliminate most of the computations(possibly all, if they don't influence the control flow), but the control flow of the program should be maintained at all cost. I did see an optimization pass to print the CFG of a function without its body to a dot file, but I am interested in generating the

Hi, I have written a code layout feedback directed optimization pass, which currently works for basic block reordering and function reordering. It very effectively improves the speedup (we could improve Python by 30%). The profiling method is window based context sensitive which is based on reference affinity (

Hello, I need interprocedural alias analysis while I'm using GVN for infeasible path analysis. So, I've tried "-steens-aa" from poolalloc project, but it doesn't seem to be working as I expected. For example, int global; int bar(void) { return 5; } int foo(void) { int a; scanf("%d", &a); if(global) a = bar(); return a; } In this case, I

Hi, 1. How can I report a bug or commit a patch to the giri progject? I doubt this central commit list is the right place. 2. Are you still maintaining the giri project any more? Thank you.

Hello everyone, I have been interested in compilers, especially in the optimization aspects from quite some time now. I don't know if I have a decent background to brag about, but all I can say is that I have tried very small things related to building a compiler [0]. However I admit that I am still new to a lot of things. Like many others who are interested in compilers, I am interested

Thanks for your reply. Yes, I was about to recurse over the use list of the argument in the called function. I did not want to pursue that because with this solution, I am going to implement the interprocedural part myself and was wondering if that was not already done. I was not also 100% sure that this will work for any type of arguments. If, based on your response, this is my only solution

Hi, I'm looking for interprocedural AAs and have, of course, found https://llvm.org/docs/AliasAnalysis.html. However, the AAs that come bundled with LLVM do not work interprocedurally in a way that I need it (on/with stack variables). The two interesting looking AAs come with the optional `poolalloc' module that hasn't been updated in years (I guess

Hi Jakob, I have spent last 4 weeks trying to figure out how to implement Interprocedural Register Allocation. I must admit that I was really overwhelmed with LLVM's codebase while trying to figure this out :) There is so much to know! I think I have reached a point where I have some sort of basic understanding of what needs to be done, but I need some help from here on. So here is the

If I turn on one of the llvm interprocedural optimizations without turning on the analysis it uses. will the analysis be turned on automatically ? Thanks Xin

Hi Everyone, Can Someone tell me all the interprocedural optimizations that LLVM 2.1 supports. Thank You, Naineet Patel CSE IITB

Daniel, OK, I see your point. My understanding was that VNDAG is an internal representation, not meant to be used by VN's customers (that should really care for classes of congruency, nothing more). Also, I thought that VN's results are available for a single function at a time. It seems that NewGVN provides access to VNDAGs computed for the whole program -- which enables its usage in

We have done a few class projects on static interprocedural slicing but they are all of "course project" quality.

Hello, I had a look at the global variable optimizer. In my opinion it handles a few special cases, when global variables can be replaced by local variables or be removed completely. Basically I think that this problem could be solved with an interprocedural live value analysis for global variables more generally. An assignment to a global variable can be removed, if this global variable is dead

There is/are implicit dependency for the optimization on its analysis. So, if you run the optimization, the analysis will be turned on implicitly, through the PassManager.
