Hi Terry, I'm not part of that project but I'll take a stab at answering your question. Vikram Adve is probably the person to answer. The point of Lifelong Code Optimization is to continuously optimize the code during its lifetime, even while it is running. By profiling the code, it is possible to discover the program's hot spots and intensely optimize those portions of the program.

Hi Terry, Reid is exactly right about the benefits of static (link-time) optimization for whole programs. When all libraries are available, it could alllow significantly better optimization without run-time overhead. But it is increasingly common today for libraries to be dynamically linked. In these cases, you could get the benefits of LLVM optimization in two ways, *if* you compile the

In the past, I've just referenced Chris's CGO 2004 paper when referring to LLVM: C. Lattner and V. Adve. LLVM: A compilation framework for lifelong program analysis & transformation. For sub-projects like Clang and DragonEgg, I just cite the URLs: [4] Clang. clang.llvm.org. [5] DragonEgg. dragonegg.llvm.org. I don't know of any canonical references for these. On Sun, Apr 14,

Hiya, Now I have figured out how to read disks using dd to make LEDs blink, I want to write a little script that iterates through all drives, dd''s them with a few thousand counts, stop, then dd''s them again with another few thousand counts, so I end up with maybe 5 blinks. I don''t want somebody to write something for me, I''d like to be pointed in the right

hello, I have a question about the llvm jit. Does it use the profile information generated during runtime to enhance the generated code for arm processor? according to 'LLVM: A Compilation Framework for Lifelong Program Analysis **<http://llvm.org/pubs/2004-01-30-CGO-LLVM.html>' it is available but can't find it in the current source code. I really appreciate any help. Thanks in

So, what is the use of the profile passes in LLVM? Also, does llvm detect hot blocks of code for recompilation?

Its basic I'm not sure that I agree with this. Compilers need to be extremely predictable and

Dear LLVM devs, If one were to (academically) cite the LLVM project in the general sense, what would be the recommended reference - ie. one that gives a recent and complete overview of the system? Thanks! Vesa

I"m not sure there is an official citation, but you can probably just look at the papers on <http://llvm.org/pubs/> and see what they do. -- Sean Silva -------------- next part -------------- An HTML attachment was scrubbed...

I just had a chance to read some of follow-up comments on Reid's initial document. I agree with Chris's discussion below of what is needed for users to get IPO/lifelong opt'n via LLVM without extensive changes to Makefiles, and about what .o files should contain. This is in perfect agreement with what I just said about how users should view LLVM. --Vikram

LLVMers, As part of my work on bug 353: Create Front End Framework And Compiler Driver (http://llvm.cs.uiuc.edu/PR353), I'm starting a discussion on the design and requirements of the compiler driver. If you have comments on this, by all means PLEASE chime in. This is by no means cast in stone. The results of the ensuing discussion will be documented in PR353 (and elsewhere) and I'll use

Taking the address of a function inhibits optimisations for that function. Essentially any ABI changes are unavailable if we can't adjust the call site to match. The case of interest here is when a given function is called directly and indirectly, and we don't want the latter to impose a cost on the former. One approach to avoid the ABI constraint cost is to extract/outline the body of an

I won't bother quoting all of Moz's statements of how sound is interpreted by those blessed/cursed with tape recorders in their heads :) I will add that his whole explanation of perfect pitch perception easily offers an explanation as to why some individuals will only archive flac/pac/ape (Moz - do you?) and those of us that do not perceive that level of detail and are fine using ogg

Hi, when trying to optimize socket transfer rates under Cygwin, it turned out that the underlying WinSock implementation is surprisingly sensitive to buffer sizes. The latest Cygwin from CVS is now setting the socket receive/send buffers (SO_RCVBUF/SO_SNDBUF) to 64K, rather than keeping them at their default values of 8K which thwarts data transfers a lot. While testing I still had the problem
