Hi, all I'm using profiling mechanism provided by LLVM. What I did is, $ ./${LLVM_SRC}/utils/profile.pl hello.bc But it turned out that llvm-prof failed to interpret the profile dump, llvm-prof gave me the error message below. llvm-prof: Unknown packet type #5! Any idea? Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica,

I'm having the same problem. Does anyone know what's causing this?

Hello. I've used these commands to compile the code below with edge-profiling-instrumentation: $> clang -emit-llvm -c rnd.c -o rnd.bc $> opt -insert-edge-profiling rnd.bc -o rnd-prof.bc $> clang rnd-prof.bc -lprofile_rt -L/paths/lib -o rnd this is the source: #include <stdio.h> void hello() { printf("hello\n"); } int main() { int i=0; for (i=0; i<149; i++)

Turns out I was using `opt -profile-loader` instead of `opt -path-profile-loader`. Switching to the path profile loader fixed the problem.

I can only guess llvm-prof does not recognize the profiling data. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia

It is solved. The problem was trying to profile while the llvmprof.out has not been generated. Below, the sequence of instructions that worked with me $ clang -03 -emit-llvm hello.c -c -o hello.bc $ opt -insert-edge-profiling hello.bc -o hello.profile.bc $ llc hello.profile.bc -o hello.profile.s $ clang -o hello.profile hello.profile.s

I did an update about 1/2 hr ago, and instead of failing to link with -O4, I'm getting an error elsewhere in the compile. I think I need to stop chasing the bleeding edge. pandora 142% svn update At revision 147455. pandora 143% uname -a Darwin pandora.psychiatry.uiowa.edu 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386 pandora 144%

We recently upgraded to rspec2 / rails 3 and our specs are taking a very long time to run. It takes nearly 12 minutes before the first dot comes out. Before the upgrade, our entire suite of 6000+ specs would run in about 6 minutes. The majority of the delay seems to be during the loading of the spec files. Adding instrumentation to the rspec-core lib/rspec/core/ command_line.rb, you can see

hi i have another question, how can change the display of result on screen?For this purpose, i have modified the llvm-prof file and make it again. But received no results

I used to be able to build LLVM (from source) under Cygwin for llvm-2.2 and previous releases, but can't continue the trend since the release of LLVM 2.3. I have tried a wide variety of gcc compilers (gcc 3.4.4, 4.1.2, 4.2.4 and 4.3.2) on cygwin, they all fail at the same location: C:\cygwin\home\czhao\ResearchTools\LLVM\2.3\obj2.3>make make[1]: Entering directory

Hello, I'm starting to play with LLVM today and I've trouble compiling it. I'm working under Windows Vista, with the gcc from Cygwin: gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) Is LLVM supposed to work with this version of GCC (probably using the -mno-cygwin option to get a Mingw-like behavior)? The LLVM source tree is from the current SVN trunk. Compilation

I use FoldingSet to save some data structures. And I found somehow it always abandon a new node. I tracked the bug into the ComputeHash() function of FoldingSet. It computes the SAME hash value for these two 32-bit unsigned integer sequences: size: 17
