Hi, I have searched R mail list archive and couldn't find my answers. The R extension describes how to make use of Rprof to profile R code. gprof can be also used for the same purpose for the C codes when the C codes are written independently and provided with a main() function. I'm currently writing R codes meshed with C Codes, and use .Call as the interface between the two parts.

Hi, I am trying to compile a simple program with Clang 3.3 on Linux and used -pg and -O2 option. The program would crash with segfault. Interestingly if I compile it with -pg option only it works. Do you have any idea why it crashes? And any workaround? $ cat myprog.c int main() { return 0; } $ clang -v -pg -O2 myprog.c clang version 3.3 (tags/RELEASE_33/final) Target:

If anyone has some reasonably valid gprof output laying around (from a vorbis encoding run), could you email it to me?

I have inherited a legacy S-plus system with about 10,000 lines of S and 10,000 lines of Fortran. It's now running under R. However, I would like to profile the fortran code with gprof or prof for performance tuning. I've successfully linked the .so file into a simple C driver program and profiled, but I can't seem to get profiling to work when using dyn.load() to use it from R. Do

Hello, again. I'm interested to learn how programmers develop & test C/C++ code with R packages in Linux. I've been reading R source and the manual on Writing R Extensions but there are just a couple of details I can't understand. I wish I could watch over a developer's shoulder to see how people actually do this. I've tested a bit. I am able to take package.tar.gz

Folks, I'm trying to profile a code compiled with Clang and I'm getting a segfault on mcount independently of the program I run: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7b1245b in mcount () from /lib/x86_64-linux-gnu/libc.so.6 (gdb) bt #0 0x00007ffff7b1245b in mcount () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007ffff7dd6588 in ??

Hi, I'd like to propose a GSoC project with the goal of implementing a library for profiling instrumentation of LLVM IR. Currently, my idea is make the library general enough to insert arbitrary code or a call to a void(*)(void) before or after reads/writes from a specified variable or in the prologue/epilogue of a specified function. I would like to build more than this on top of the

I'm asking here, rather than R-devel, because it seems to be a Linux specific question and because I'm using Ubuntu-9.04. I'm trying to profile an package, and got errors, so I decided to follow BDR's (http://tolstoy.newcastle.edu.au/R/devel/06/02/4254.html) example exactly, and got same problem. Can anyone replicate? $ sudo mkdir -p /var/tmp//usr/lib/R/library/stats/libs $

PROFILE OUTPUT PROCESSING TOOLS FOR R ===================================== This package provides some simple tools for examining Rprof output and, in particular, extracting and viewing call graph information. Call graph information, including which direct calls where observed and how much time was spent in these calls, can be very useful in identifying performance bottlenecks.

Howdy. I'm working on Altivec versions of some of the libFLAC functions. I figured the best candidates would be those that had MMX/SSE/3dnow versions, and I picked FLAC__lpc_restore_signal() to do first, since it's relatively simple. In stepping through some runs, it appears that 'order' mod 4 is always 0. Is that guaranteed, either by the format or by higher functions in the
