You can call them the same way a C++ file compiled with llvm-g++ would call them. Essentially, it's complicated enough that you probably don't want to do it for any interface of

Sorry could you help me? I have problem with using LLVM and some code in C (.so file) I want to use (simply example): mylib.c: #include <stdio.h> void printString(char *str) { printf("%s", str); } mylib.h: #ifndef MY_LIB_HEADER #define MY_LIB_HEADER void printString(char* X); #endif /////////////////////////////////////// Normally in C++ I do this: g++ -fPIC -c mylib.c

Hmm.. I didn't explain the problem completely last time. I am creating a drop-in replacement for gcc and gfortran that runs an additional pass on the bitcode before generating the native binary. Here's whats happening: If the source code compilation process builds a static library (.a archive file), I need a means to link the `.a' file statically into the application. So if the

I see. And what's the purpose for outputting bitcode into *.o and *.a files? Do you want to perform an LLVM pass on linking step? 2011/9/13 Ashay Rane <ashay.rane at tacc.utexas.edu>: > Hmm..

No, I am running the LLVM pass at the compilation step. So by the time I reach the link step, the transformed bitcode has been generated. Ashay On Mon, Sep 12, 2011 at 4:12 PM, Dmitry N.

Sorry, at what step do you need archive? llc emits binary, it does not perform any linking, thus it does not need anything except the input bytecode file. Then during linking you can link whatever archives of binaries you want. 2011/9/13 Ashay Rane <ashay.rane at tacc.utexas.edu>: > Thats correct.

Hi, This is Crystal. I have some questions about llvm-gcc. Could you please give me some advice? Thanks in advance. Problem description: Env: llvm-gcc (GCC) 4.2.1 gcc (GCC) 4.1.2 OS:fedora7 I tried to compile a C programme test.c with llvm-gcc by task: [root at localhost mylib]# llvm-gcc -emit-llvm test.c -Llibmylib.a -c -o test.bc [root at localhost mylib]# lli test.bc after running the command

Thats correct. But using llc becomes a problem when I have archives (.a files). I could, in theory, extract its contents to a tempdir and then use llc and link but just wondering if there is a more elegant solution. Ashay On Mon, Sep 12, 2011 at 3:00 PM, Dmitry N.

Hi, I need to produce a standard report for several variables in Sweave and thus would need the possibility to define a TeX-command which includes R-code like \newcommand{\meansd}[1]{The mean is \Sexpr{mean(#1)} and the standard deviation is \Sexpr{sd(#1)} . } and then just write \meansd{age} in the latex code to get the whole sentence. The above does not work, since

i want to study R programming by studying the existing code from R itself,but i don't know how to read the code,can any one give me some guide? my R is installed in /usr/lib/R/ [ronggui at mylinux ronggui]$ /usr/lib/R/ afm bin doc etc include library modules share > version _ platform i586-mandrake-linux-gnu arch i586 os linux-gnu system i586,

Hi all together, all answers to my first posting didn't help to solve my problem. Maybe this can help you. When I'm doing: smbclient -L MYLINUX -U MYUSER I get the following message: Added interface ip=195.90.254.xxx broadcast=295.90.254.255 nmask=255.255.255.0 Password: <enter password for myuser> Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 2.0.5a] Tree connect failed: ERRSRV -

I can repeatably crash R (segfault) by doing n <- 10 z <- data.frame(a=1:n,b=1:n) View(z) and then hitting the "End" key on my keyboard. I haven't got debugging going yet, but running under gdb (without debugging symbols) does give this: 0xb7b63583 in strlen () from /lib/tls/i686/cmov/libc.so.6 R version 2.6.2 (2008-02-08) i486-pc-linux-gnu [Ubuntu Gutsy] locale:

I am using the .Call interface to call c++ code from R. For that, I am trying to create a dynamic library (mylib.so) using "R CMD SHLIB" by linking my own c++ code and an external c++ library (blitz++). The makefile works fine on my Mac, produces mylib.so and I am able to call .Call() from R, but on a linux server (I think Debian), I got the following error: ---------- /usr/bin/ld:

Hi, I have built a library that consists of a piece of C code and some R functions. To build it into a library that I can load using library() command, I have followed "Writing R Extensions" and made sub-directories such as mylib/R and mylib/src. But when I run R CMD INSTALL mylib, nothing seems to be happening with src directory, i.e., no C compiling. I have probably missed some key

Dear R users, we are trying to build a R package that includes a precompiled shared library, let's say mylib.so. We created the skeleton of the package and we moved the mylib.so file into the libs folder that we created at the same level of the folders man and R. Moreover we created the file NAMESPACE and we added the line useDynLib(mylib, .registration=TRUE). The building step seems to work

hi, i'm having some trouble getting a package to load a shared library object in .onLoad(...) i have a shared object file, say "mylib.so". if i start an R session, and via the CLI specify the actual library via: > dyn.load("mylib.so") everything works quite well (i.e. i can then follow with some .Call (...) methods) now, i'd like to include this shared library in

Hi Everyone, When I used llvm-objdump to disassemble an ELF armv7 or thumb I have this error message: llvm-objdump: warning: invalid instruction encoding This message appears directly into the output and the output is mostly wrong (the invalid instruction create a shift in the addresses) : 1a6d: ff 2f e1 08 stmeq r1!, {r0, r1, r2, r3, r4, r5, r6, r7, r8, r9, r10, r11, sp} ^ 1a71: 30
