similar to: llvm outlining question

CodeExtractor sort of does this. First, it's a utility, not a pass - you'd still need to wrap it up with pass that actually causes it to outlines what you want it to outline. Second, it's a bit buggy. There are, as far as I know, two in-tree users of this utility: bugpoint, and partial inlining. Both of them are fairly specialized use-cases, and don't actually exercise the full

I'm not aware of anything else in LLVM that performs outlining. Ayal (CCed) may be able to help you regarding CodeExtractor fixes.

Hi All, I'm wondering if its possible to write degree in symbol. I would like y-label as "Temperature (degreeF)". where degree should be in symbols. Thanks in advance, #R Code library(lattice) data(barley) barchart(yield ~ variety | site, data = barley, groups = year, layout = c(1,6), ylab = "Temperature (degreeF)", scales = list(x =

Hi, I have some questions regarding outlining (extracting piece of code into a function): 1. Is there an outlining pass in llvm (IR)? I've found out CodeExtractor pass, but I'm not sure it's exactly the same idea. 2. How do I set the function name? And another question: Where do I control the execution of my pass? I'm writing a pass that first works on

Just wanted to know is the code size reduction technique called outlining is implemented as a part of JIT LLVM (Orc JIT) or is it separately implemented as a part of code optimization.

Hi David, So I've began doing some implementation on the outlining portion of the code. Currently, I got the partial inliner to outline cold regions (single entry, single exit) of the code, based solely on the existence of ProfileSummaryInfo (ie. profiling data). However, I have some concerns on how this will co-exist with the existing code that peels early returns. The control flow looks

Moi! I upgraded Xen-2.0.1 to Xen-2.0.5 (testing) and everything compiled cleanly. I''m still able to boot dom0 and start domUs but networking doesn''t work anymore. xen-br0 appears in dom0, but vif-interfaces now only when ifconfig -a is used. Interface appears in domU and all seems to be fine, except no any data doesn''t move in any direction. I can''t even ping

Hi Jessica, Thanks for the feedback. I believe the existing partial inliner pass does use some common utilities like the code extractor to do outlining. Is that what you're referring to? I don't recall seeing any other passes that has outlining other than the machine outliner, but I may have missed something. I briefly looked at River's RFC and it seems he's mainly utilizing

Dear R-help community, I am working with multidimensional contingency tables and I am having trouble getting loglm to run on all dimensions without typing out each dimension. I have generated random data and provided output for the results I want below: d1.c1 <- rnorm(20, .10, .02) d1.c2 <- rnorm(20, .10, .02) d2.c1 <- rnorm(20, .09, .02) d2.c2 <- rnorm(20, .09, .02) d3.c1 <-

Hi Reid, It occurs to me that we should probably move the cppeh outlining tests, since they aren't actually X86-specific. We should probably also add an ARM+Windows run line to them. I'm torn between whether they should go in the test/CodeGen/CPP folder or in a new test/CodeGen/Win (or test/CodeGen/WinEH) folder. Thoughts? -Andy -------------- next part -------------- An HTML

Hi David, The only reason I can see to use the 'pattern matching' part as a fall-back is in case we cannot inline the (what I'm assuming would be) a much bigger hot-path-only cloned function for whatever reason. What I'm assuming here is that after cold-region outlining, we may still have a large portion of the original function body to attempt to inline, whereas the pattern

I think the "Motivation" section explained that. I too first thought about "why not at IR?" but the reason looks like MIR, post-RA has the most accurate heuristics (best way to know looks like actually getting there). Do you know if there is any experimental pass that relies on deriving heuristics by a feedback loop after letting, ie. a duplicate module/function/block continue

I second the fact that a way to outline specific function regions independently of the partial inliner sound very useful. I am not sure however if we would want a mode within the partialInliner or something completely independent. As a general question, does anybody has a clear idea of what are the constraints on the region CodeExtractor is currently able to handle ? Going through the code, it

Hi, I let Jessica give more details but here are some insights. MIR offers a straight forward way to model benefits, because we know which instructions we remove and which one we add and there are no overhead of setting up parameters. Indeed, since the coloring will be the same between the different outlining candidates, the call is just a jump somewhere else. We do not have to worry about the

Daniel, I wonder what the NewGVN would generate for the following C code: int a, b; int foo() { return a + b; } int bar() { return a + b; } ? Obviously, the expressions would be the same ("value1 + value2"), but a single operator is not worthy to be outlined. What classes of congruency would be assigned to operands? The same for both reads of "a" and "b"? If
