similar to: [LLVMdev] Regarding profiling with llvm

Hi, I am trying to obtain basic block profiles for mediabench g721 benchmark. I have successfully built llvm in profile_enabling mode. Then so as to find out the block execution frequency, I ran the command, analyze encode.out-cbe. It generated gmon.out which I read using gprof. However, I did not get the basic block level execution frequency. Can anybody help me as to how I can extract the basic

Hi, Standard approach to profiling dynamically loaded libraries with gprof doesn't seem to work with LLVM: export LD_PROFILE=Mylib.so export LD_PROFILE_OUTPUT=. make ENABLE_PROFILING=1 // compiling my project opt -load Profile/Mylib.so -options... but no Mylib.so.profile (or gmon.out) is produced. Profiling libc.so.6 usage by "ls -l", however, works fine. Could anyone explain

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

Currently, we don't support using separate object trees that are subdirectories of the source tree. In other words: Will work: ========== SRC_ROOT=/home/yue/llvm

Hi, I am working on an R package which includes some C routines. I would like to profile the C routines (built with GCC under Debian Linux). I tried running R with LD_PROFILE=/path/to/C/library.so R and executing functions that would invoke the code therein. The code takes about twice as long to run with LD_PROFILE set than without, so I am guessing that profiling is taking place. However,

Dear Tobias Grosser, Today I have rebuilt the LLVM-Polly in Release mode. The configuration of my own testing machine is: Intel Pentium Dual CPU T2390(1.86GHz) with 2GB DDR2 memory. I evaluated the Polly using PolyBench and Mediabench. It takes too long time to evaluate the whole LLVM-testsuite, so I just choose the Mediabench from LLVM-testsuite. The preliminary results of Polly compiling

Dear Tobies, Sorry for the late reply. I have checked the experiment and I found some of the data is mismatched because of incorrect manual copy and paste, so I have written a Shell script to automatically collect data. Newest data is listed in the attached file. Tobies, I have made a simple HTML page (attached polly-compiling-overhead.html) to show the experimental data and my plans for this

Hey guys, I am trying to speed up some of my LLVM/llc passes. Is there a way to use something like gprof on llc? If not, do you guys know anything that I can use to discover which routines of my passes are taking most of the time? thanks, Fernando

I am trying to do some research that involves instrumenting LLVM IR, that I need to test for performance and scalability on a bunch of systems. I've started trying by trying to get sparc-sun-solaris2.10 (niagara) working. It appears that neither llvm nor llvm-gcc will build natively on the system, so I think that I need to build an llvm-gcc cross compiler. The documentation for building

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, Question I had was if someone has tried executing Mibench or Mediabench benchmarks using llvm. I am trying to do simple qsort benchmark in the Mibench benchmark suite. I substituted llvmc instead of gcc in the makefiles. But I am getting the following error. "llvmc qsort_small.c -O3 -o qsort_small -lm llvmc: Configuration file for 'c' is not available. make: *** [qsort_small]

Hi, Sean: I'm sorry I lie. I didn't mean to lie. I did try to avoid making a *BIG* change to the IPO pass-ordering for now. However, when I make a minor change to populateLTOPassManager() by separating module-pass and non-module-passes, I saw quite a few performance difference, most of them are degradations. Attacking these degradations one by one in a piecemeal manner is wasting

Hello all, I am trying to install the llvm-gcc front end to use it in one of my projects, but I got stuck..

Dear R-help, Can some one tell me how to profile compiled code dynamically loaded into R? Here's what I tried on our dual Opteron running SUSE Linux Enterprise Server 8 (GCC 3.3): Start with R-patched dated 2004-06-07: (I also had MAIN_CFLAGS="-pg" in config.site.) R is now configured for x86_64-unknown-linux-gnu Source directory: . Installation directory:

Hi, LLVM 2.1-pre1 test results: Linux (SUSE) on x86 (P4) Release mode, but with assertions enabled LLVM srcdir == objdir # of expected passes 2250 # of expected failures 5 I ran the llvm-test suite on my desktop while I was also working on that PC, so don't put too much trust in the timing info. Especially during the "spiff" test the machine was swapping

Hello, I was interested in how much Type-Based Alias Analysis helps to optimize code. For that purpose, I've compared three sets of benchmarks: compiled without TBAA, compiled with a default TBAA metadata format, and compiled with new TBAA metadata format. As a set of benchmarks, I've used the LLVM test suite (http://llvm.org/docs/TestingGuide.html#test-suite-overview) which has a lot of
