Hi, It was suggested that I post my question regarding a LLVM 3.4 performance regression to this mailing list, rather than stackoverflow. So here is the link: https://stackoverflow.com/questions/22902034/llvm-3-4-performance-regressed Thanks :) Jens -- Jens Tröger http://savage.light-speed.de/

Hi, all I use llvm-gcc -O4 to compile SPEC 2000, some benchmarks can't be built successfully, such as 164.gzip, 175.vpr etc. The error messages are as follows. .. zh.o unlzw.o unpack.o unzip.o util.o zip.o -o gzip bits.o: file not recognized: File format not recognized collect2: ld returned 1 exit status specmake: *** [gzip] Error 1 specmake options 2> options.err |

Hi All, I am migrating a build system of an existing project from 'Object files' based executable generation to 'LLVM Bitcode' files based exe generation and applying OPT pass to LLVM Bitcode. I found out the following 4 step procedure. Please let me know if this is the right procedure or is there any other easy way of doing it. I need to modify 'Makefile' accordingly. I

Hi Ahmad, If the Makefile contains only this command, then it is not worth spending time on GoldPlugin. If you are building a large project, then it will be simpler to use GoldPlugin. The steps you are using seem right. You can possibly combine the last two steps (3&4) using only 1 clang command. clang -g -O2 -o .libs/mergedexe .libs/mergedbc.bc -pthread -Wl,--export-dynamic

I apologize in advance for the simplicity of this question. I use R 2-3 times a year, and I seem to forget more in the intervening months than I learn during my days of panicked reading.... I HAVE tried looking at the help resources; I'm just not very good at understanding them. I have a dataframe with 18 observations of 5 different things, and a second dataframe with and estimate for those

Hi All, I am using clang to compile Mysql source code. Because I want to do some inter-procedural analysis, hopefully, I want to get a .o(bitcode) file(a module) containing all possible function declarations and definitions. Is it possible to do that ? Or you guys have some suggestions? To be clear, like Mysql, there is a mysqld routine, which is a major routine. I want to mysqld.o(which is

Does anyone have an R Syntax Highlighting file {userDefineLang.xml} for NotePad++?? I've started one, but I'm not so happy with it.

I'm trying to test a bitcode file that I created using the LLVM API. Using llvm-g++, how can I compile.a C++ file and link it against my bc file ? I try to call a single function in the bc file from the c++ main function. Envoyé de mon iPhone

I'm trying to prepare some cross tabs, looking at a number of variables against a variable "connector" which has 2 values: "OD Passenger" and " Connector". When I produce a xtabs one way I have observations under "Connector" but against a different variable "Connector" shows all 0 values. What is wrong? I've looked into the na commands

It appears that llvm-ld can handle bitcode files but llvm-gcc complains that when I pass bitcode files to it. I assume that means that llvm-gcc does not use llvm-ld by default. Is there a way to force it to use llvm-ld? Bill Wendling wrote: > You do it by using the -flto flag. But you will need a linker that's able to handle the bitcode files. The Apple linker can and so can the

Hi, We're currently upgrading KLEE to work with LLVM >=3.3 and we've hit a problem. It seems r172749 removed support for linking a bitcode archive into a module. KLEE unfortunately depends on this to link in its runtime ( which amongst other things provides a C library [5] ). A first attempt at linking in a bitcode archive ourselves can be seen in [1]. This approach does not work

I have recently begun experimenting with Asterisk, and have been mightily impressed by its capabilities and flexibility. I have run across one problem, however, that challenges my ability to use it as a production system. My Asterisk box has a public Internet IP, and works great with SIP (ATA 186) clients that also have public IP addresses. Unfortunately, most of the locations that I would

I can't figure out the syntax I need to get subset to work. I'm trying to split my dataframe into two parts. I'm sure this is a simple issue, but I'm stumped. I either get all or none of the original "rows". > XTTable <- xtabs( ~ direction_ , SurveyData) > XTTable direction_ EASTBOUND

I have a dataframe from an On-Board Survey with weights ("expwgt") and variables for up to 8 used lines: VEH1 through VEH8. The lines are labeled "MT-..1" through "MT-902". I want to know how many transfers there are between MT-802 and MT-901. That is, when one of them is VEHx and the other is VEHx+1 or VEHx-1 E.g. {VEH1 = MT-802 AND VEH2 = MT-901 } plus {VEH2 =
