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++.

...s that _OC_str, and _OC_str1 are structure variables, but I have never seen such way of declarations, definitions, and initialization of structure in C code. I guess it may be supported in some standards of C. Could anyone please give me some information about the problem?

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 */ t...

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

Hello, How do you print a variable name in a for loop?

The IR has the same features, but some assumptions on the semantics are different. I can give you two examples: 1. Classes in C++ are like C structures in IR, but...

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,

...in situations where the p2m entry is changed but the mfn is the same, the VTd tables will be unnecessarily flushed. old_entry is left untouched in the second case, since having a present old_entry will cause the an unnecessary check to be taken at the end of the function.

Dear R users, Are you worried about the parallel trends assumption in your panel regression? Use fixed effects individual slope models, controlling for heterogeneous trends! I am very pleased to announce that the package feisr is now available on CRAN! CRAN: https://cran.r-project.org/package=feisr GitHub: https://github.com/ruettenauer/feisr The packages feisr provides a function to estimate fixed effects individual slope (FEIS) models. FEIS models constitute a more general version of the often used conventional fix...
