similar to: [LLVMdev] C Backend Ressurected

I don't know how good it is, but the applications seem obvious. e.g. compiling programs in any of a number of original formats to run natively on CPUs that have a working simple C compiler (maybe only K&R or C89) but don't have an LLVM back end. The source program could be in modern C, C++, or any other high level language or assembly language with a translator to LLVM. On Tue, Aug

It provides a useful starting point, but I agree with Jim that it is not a complete solution and requires rework of the results in a lot cases. I think we could improve it further to address these issues but that work is nontrivial. If you are deciding between a quick and dirty implementation of a custom backend vs. the C backend, then the C backend is sometimes preferable in my experience

I can't see why you'd want to do this, no. -eric On Tue, Aug 19, 2014 at 8:02 PM, Isaac Dupree < ml at isaac.cedarswampstudios.org> wrote: > Is the C backend at all suitable to be adapted to emit OpenCL code?

I want to transform elf binary to llvm IR, and do some instrumentation based on llvm. Is there any tool which can do the transformation? Thanks in advance. - mudongliang -------------- next part -------------- An HTML attachment was scrubbed...

Hi, It looks like the DeadStoreElimination optimization doesn't work across BasicBlock boundaries. The project I'm working on (https://github.com/trailofbits/mcsema), would tremendously benefit from even simple cross-block DSE. There was a patch to do non-local DSE few years ago (http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-January/028751.html), but seems that the patch was never

Hi all! There is doc about tglben backends: http://llvm.org/docs/TableGen/BackEnds.html May be should to add link at https://github.com/draperlaboratory/fracture/wiki/How-TableGen%27s-DAGISel-Backend-Works I remember when I first met the LLVM it would be very useful. -------------- next part -------------- An HTML attachment was scrubbed...

I agree, but I have no experience with LLVM doc. The job is very simple: add link at page https://github.com/draperlaboratory/fracture/wiki/How-TableGen%27s-DAGISel-Backend-Works into doc page http://llvm.org/docs/TableGen/BackEnds.html But how I can do it?

Hi - Not sure if anyone else saw this or cares about a decompiler (not personally tested) https://github.com/draperlaboratory/fracture I wonder if they have been in contact with anyone in the community in getting this upstreamed. Does it look interesting to anyone else? (thoughts/random comments/feedback)

Dear all, I'm aware if y has two separate functions (depending on the conditions of x) you can use the ifelse function to separate y into two separate functions depending on input. How do you do this if there a multiple different conditions for x? for example, y fits the following between t>0 & t<15----->function(t) t^2, y fits the following between t>15 &

Hi all, I am trying to import some functions into a script and am having difficulty in doing so. I am able to import a series of functions from a .tex file into my script, and call on each function by column name, however R reads them as data rather than as functions and I am struggling with the syntax to make R read them as a function instead. Below is a small set of the things I have tried:

Hi all, I am attempting to use latin hypercube sampling to sample different variable functions in a series of simultaneous differential equations. There is very little code online about lhs or clhs, so from different other help threads I have seen, it seems I need to create a probability density function for each variable function, and then use latin hypercube sampling on this pdf. So far, I

Hi all, I'm having trouble locating a script that will allow to me to create graphs that show compound functions as a function of the simple function, rather than just x (or time as it is in my case). Currently I have the following functions defined in my script: > > > T1<-function(t) {27.5-12.5*cos(2*pi*t/365)**} > and > > B1<-function(T1,t)

Hi all, I have a matrix simulating migration in a spatial model. I want to be able to define movement (the values of m1, m2 and m3) as only != 0 between adjacent patches and contingent on certain conditions as defined in the function. Here is the code: WET<-function(t) {everglades$precipitation[t]} #simply reads precipitation data from a csv, value is numeric AB<-function(WET,t)

Hi all, My apologies if this message is incredibly inept but I am very new to both computer programming and to R. I am working with the odesolve add-on and have the following function defined RVF_Single <- function(t, x, p) within the script I also have the following functions defined: T1<-function(t) {T1<-27.5-12.5*cos(2*pi*t/365)} and B1<-function(T1,t)

Hi everybody, I'm trying to create a numerical data frame on which to perform PRCC. So far I have created a data frame that consists of function/vector output that displays in numerical form, but when I try and run PRCC (from epiR package) I get the following error message: "Error in solve.default(C) : Lapack routine dgesv: system is exactly singular" It appears this is because

Hello, I'm interested in LLVM as an opportunity to support C++ programming for legacy MCUs (8051, PIC1x, etc.). Recently, I tried to use C Backend as means to achieve this. As C Backend was removed in recent LLVM versions, I started with LLVM 3.0 which was last version to include it. For starters, I played with MSP430 target, which is supported by LLVM, so allows roundtrip experiments

Hello Everyone, My company is about to deploy * as replacement for our existing commercial Altigen PBX. Meanwhile, I've been trying to find the best cost effective SIP VoIP phone which we can use in office for 20-30 employees, as well as a few remote staff. Normally I wouldn't post about a VoIP phone, however, this phone was released less than a week so I thought I'd give some
