similar to: [LLVMdev] Bitwidth analysis?

We have a bitwidth analysis that can be downloaded. It is not in LLVM. There should be a link in the paper: http://www.cs.utah.edu/~regehr/papers/pldi075-cooprider.pdf John Regehr

Dear John, thanks for pointing it to me. I just downloaded and installed CIL. However, I am getting an error when I run "make check", or when I try to compile the blink application, and I am sending you the error notice below. In any case, do you think it is possible to get some sort of 'dump' of the target C program with some bitwidth information, once I get your

Hello, I am wondering if there is any way to figure out bitwidth of Machine Instructions. I see that ValueType information is available for nodes of DAG, but I couldn't find similar info for Machine Instructions. I particularly need this information for x86 target. I appreciate your help and comments in this regard. Thank you, Babak

Hi, The lli interpreter crashed for the following case: ; ModuleID = 'x.c' target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32" target triple = "i686-pc-linux-gnu" define i32 @main() { entry: %retval = alloca i32 ; <i32*> [#uses=2] %tmp = alloca i32 ;

Does llvm have a pass that minimizes the bitwidth of llvm instructions? For instance:   %8 = and i32 %7, 63 63 is 111111 in binary. So the 'and' instruction only requires 6 bits. We could rewrite the above code as:   %8 = trunc i32 %7 to i6   %9 = and i6 %8, 63 Since we only need the lower 6 bits we could also propagate this change backwards to reduce the bitwidth of prior

Hello, My problem is to add selinux policies can any help to say what is wrong with my policies I write this! semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html(/.*)?/ typo3conf(/.*)?" I have more instances from typo3 I found this construct in the selinux policies "/var/www/html(/.*)?/uploads(/.*)?" but my is not working ? and I have only errors? neverallow

I've actually got an implementation of this as an arbitrary precision integer extension that I've written up an RFC for (but not submitted). Below is my copy/pasted RFC (again, not reviewed, but I DO have an implementation of it that I need to prepare for review). I suspect my implementation will do what you need out of it. Its actually more significant than just adding a normal

Chris, LLVM is an excellent piece of work, LLVM is one of the few project I know that has used the mysterious GCC front-end. I think it will be a great contribution to the community if you could writeup and document how to interface to the GCC front-end data-structures (like LLVM has done). Specifically: a) detail the gcc front-end tree data-structures b) how to go about interfacing to them

I have experienced this myself. It is very upsetting. (Sent from iPhone, so please accept my apologies in advance for any spelling or grammatical errors.) > On Jan 19, 2017, at 2:57 AM, Fabian Arrotin <arrfab at centos.org> wrote: > > log

Hello, I have a dataframe with a column 'col' of expressions of the form 2*3+4*5+6*7 and substrings thereof. Now >eval(2*3+4*5+6*7) is ok. But I want it done on that column... nothing seems to work Even > cil <- dataframe$col >eval(cil[1]) 2*3+4*5+6*7 I want the elements of the column evaluated. Thanks, A. Mani Member, Cal. Math.

Hello, I was wondering, is there a way to plot estimated betas and standard deviations that I've generated? Specifically, I have the following: A matrix of estimated betas (two different betas, 4 different simulations - categories). A matrix of estimated standard errors corresponding to each of those betas. I would like to plot the estimated beta, and make a confidence

I'm still meddling with different ways to exploit LLVM's awesome JIT compilation capabilities from OCaml. Although I've managed to get minimal compilers up and running with relatively little effort, I can't help but think that I'm spending a significant amount of time reinventing the C front-end. Would it make sense to have higher-level OCaml bindings to the current CLang
