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++.

I convert C to bytecode by LLVM, and then convert the bytecode back to C by LLC, but the generated C code cannot be compiled. Could anyone give me some suggestions? Thanks! The initial C file is rather simple (hello world): #include <stdio.h> int main() { printf("hello world\n"); printf("hello world1\n"); return 0; } The two commands:

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

I am just looking for a quick answer as to whether or not OpennSSH is compatible with Digital Unix Tru64 v 4.0F.

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

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

This didn't work as I tried with 197.parser. it works without "-Wl,-disable-opt" switch though.

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? 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, ",

The commit 874f76a "PL011: fix reverse logic for interrupt mask register" introduced regression on the Versatile Express. The board didn''t receive correctly input. The timeout interrupt may be asserted when the FIFO is not empty, and no futher data is received over a 32-bit period.

Some of the run commandlines don't seem to be the *default ref* configuration. For instance, in 099.go, what's in the script is: LEVEL = ../../../.. BM=099.go ifeq ($(RUN_TYPE),test) STDIN_FILENAME = /dev/null STDOUT_FILENAME = null.out RUN_OPTIONS = 40 19 else STDIN_FILENAME = 2stone9.in STDOUT_FILENAME = 2stone9.out RUN_OPTIONS = 50 9 endif include ../../Makefile.spec95

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,

This fixes a bug in changeset 22526:7a5ee3800417, where the wrong value is read when deciding whether to flush the VTd tables. The effect is minor: 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

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.

However, I do know that your methods above run the LLVM inlining pass, albeit indirectly. If you use

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 fixe...
