Hello, I'm trying to evaluate the different register allocation algorithms on LLVM using the same level of optimizations. Using version 3.3 the current register allocators available to use are "basic, fast, greedy and pbqp". However, I'm facing the following issues: 1) I can't run basic and PBQP allocators using the command line flags of the dragonegg

Not yet. Please see Bob...

Hello LLVM developers, I'm assisting my doctor who is doing a research and he wants to use the llvm compiler, my job is to profile build the benchmarks using llvm-prof. What i want to know is the following 1- does llvm support profile feedback optimizations!? 2- when i've used the llvm-prof it's input is an object file (not binary as other compilers) my question is how could I

...to get the report. That's just a guess, though; I've never used llvm-prof myself. I bet looking at the script in the utils directory will shed light on how to use llvm-prof. -- John T.

Hello, I'm trying to evaluate the performance improvement of instruction scheduling on one of the inorder ARM processor, I was looking for ARM simulator and I found two (Simplescalar/ARM and SimIt-ARM) The code generated using llvm-2.9 and llvm-gcc and gcc 3.2. I used these command : $ llvm-gcc -O3 -o test1.bc -c --emit-llvm test1.c $ llc -O3 -o test1.s -march=arm test1.bc -mcpu=strongarm110

Hello, I'm trying to cross compile the MiBench benchmarks using LLC and ARM cross compiler the binaries generated will be used on pandaboard or the qemu-arm emulator. I have faced multiple issues during the compilation process, here are the commands used. # generate LLVM-IR for dijkstra_large.c $gcc -S -flto -o dijkstra_large.bc -fplugin=${DRAGONEGG} dijkstra_large.c # generate TARGET
