similar to: [LLVMdev] There are compiling errors when converting bytecode to c by LLC

Hi Fei Jia, What revision are you using? I suggest you to try C backend with the most recent LLVM version, if possible. I recall I had some similar C backend breakages in July-August: structs definitions were lost somewhere. To my understanding, the correct result should look like this: /* Typedefs */ typedef struct l_unnamed_0 l_unnamed_0; typedef struct l_unnamed_1 l_unnamed_1; /* Structure

Hi Bill, Thanks for reply! I am sorry I didn't express my question clearly. Examples may explain well. Now I am trying to analyze the data flow of programs. I first compile the C code to bitcode, and then apply our algorithm to the bitcode to find the dependency between statements. But as to C++ code, there are class, vector, reference, I may need to revise my algorithm to analyze bitcode

Could anybody provide me some links or pages or infos of the difference of bitcodes of C and C++? We have implemented an optimization pass on bitcode generated from C, and we are trying to find out whether it will work on bitcode from C++. Thanks! -- Best Regards, Fei Jia -------------- next part -------------- An HTML attachment was scrubbed... URL:

Another difference is the presence of exceptions in C++, which would require you to handle more IR instructions. This might not matter depending on type of analysis you do. See: http://llvm.org/docs/LangRef.html#i_invoke (Note that there is a substantial rewrite of exception handling going into 3.0) Anna.

Hi, I want to find simple loops in LLVM bytecode, and extract the basic information of the loop. For example: for (i=0; i<1000; i++) sum += i; I want to extract the bound [0, 1000), the loop variable "i" and the loop body (sum += i). What should I do? I read the LLVM API document, and find some useful classes like "Loop", "LoopInfo". But I do

Dear editor: I'm writing this letter to enquire where can I download the package of "lmtest". Can you send me this package? THanks a lot. Best regards, Shu-Fei Wu

Can PDAs be used as softphones/clients on asterisk? what i wanted to do is to set up 2 PDAs as softphone(client) which allows them to communicate each other through asterisk server(desktop) devices i have: pda compaq model 3680 pda sharp sl5500 access point desktop(asterisk) can i apply my idea on the asterisk? any guides? thanks in advance :) --------------------------------- Do

Dear all, I tried to use "step" function to do model selection, but I got an error massage. What I don't understand is that data as data.frame worked well for my other programs, how come I cannot make it run this time. Could you please tell me how I can fix it? ***************************************************************************************************

Dear all, I wrote a function test1 in test1.R. Right, I am writing another function test2 on test2.R and trying to use test1 function. How can I do? Is there any similar way like including test1.R in test2.R file? Thank You Very Much.

I am investigating some inlining issue, so I did llvm-gcc aaa.c bbb.c ... nnn.c -o output opt -inline -inline-threshold=xxx < output.bc | llc -march=c > output_inline.c 1) I noticed that even if I set xxx to 0 or even a very small negative number, many functions are eliminated. I am wondering if these functions are inlined by the frontend, or identified as deadcode. For instance,

Hi Joshua, Thanks for your great comment. I made up a ConstantVector in IR. Then I successfully use AVX intrinsics to retrieve the returned vector data. The remaining thing is that how to pass the vectors to LLVM function using intrinsics. Do you have any suggestions? Please forgive me if the question is too naive. I pasted below two IR I used. The first one works. The second one doesn't.

Hello, How do you print a variable name in a for loop? I'm trying to construct a csv file that looks like this: Hello, variable1, value_of_variable1, World, Hello, variable2, value_of_variable2, World, Hello, variable3, value_of_variable3, World, Using this: for (variable in list(variable1, variable2, variable3)){ cat("Hello,", ???variable???, variable, ",

Hi there, I am looking for a function that takes a vector as input and generates all pair wise combination of the elements of the input vector. For example, the input vector is c(1,2,3,4). The output vector is c(1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, 3 and 4). The representation here is generic. I can use a for loop to do it, but it gets slow when the number of elements of the input

Hello, I tried to write a piece of code to start vmx. This code is directly interacting with cpu instead of with virtual cpu as in xen. But every time I call vmxon, a GP exception happens. Could anybody help me on this? The following is the context 1. After booting up to the program, I disable A20M. 2. allocate a 4kb-aligned vmxon region and calculate its physical address. 3. setup
