similar to: [LLVMdev] Problems of source to source transformation of LLVM

Hi, I did experiments of the source transformation of LLVM on SPEC2000 C programs. But I found most benchmarks can't be transformed from source to source successfully. The steps are as follows. 1. I write a script to transform every .c file into .bc file, and then use llc to transform .bc file to .c files. I don't know if there are any method to transform many .c files

Hi, all I use llvm-gcc -O4 to compile SPEC 2000, some benchmarks can't be built successfully, such as 164.gzip, 175.vpr etc. The error messages are as follows. .. zh.o unlzw.o unpack.o unzip.o util.o zip.o -o gzip bits.o: file not recognized: File format not recognized collect2: ld returned 1 exit status specmake: *** [gzip] Error 1 specmake options 2> options.err |

Hi, I want to know what benchmarks can LLVM compile and run successfully. Such as SPEC CPU2000, SPEC CPU2006 or other benchmarks.

Dear All, Here is a more complete list of regressions for the platforms listed below. Some of the regressions from the previous list I emailed a few days ago have been fixed or were false positives. Thanks to all who've helped fix things. We would like to try to get as many of these fixed as possible before I create the release branch (still scheduled for tomorrow, Friday). I'll

Hi, all We want to learn the IR of LLVM. Are there any information or documents you can suggest? Or any suggestions are welcome.

Hi, I have looked at the LLVM code generation quality using small test cases and in general it is better than I thought and in some cases better than gcc. However, there are still some gap in SPEC performance. I have not looked at the root cause of those gaps. Anyone who cares about LLVM performance need to take this seriously. For fair comparison, I used -fno-strict-aliasing in gcc to turn off

Thanks David. Unfortunately many of us cannot use GPL v3 gcc so it's hard for us to investigate this. One question, can you tell if gcc is inlining significantly more than llvm? We have reports that this is one of the issue plaguing eon performance. There are also some relatively well known spec optimizations that we haven't implemented. e.g.

Hi, What is the best way to debug an llc crash using bugpoint? I am getting the following crash that I would like to reduce llc: /home/vadve/aggarwa4/llvm29/llvm-2.9/lib/MC/MCAsmStreamer.cpp:273: virtual void<unnamed>::MCAsmStreamer::EmitLabel(llvm::MCSymbol*): Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed. 0 llc

Do something like this: bugpoint -run-llc <bitcode file> --tool-args -- <llc arguments> Cameron On May 23, 2011, at 1:33 PM, Arushi Aggarwal wrote: > Hi, > > What is the best way to debug an llc crash using bugpoint? > > I am getting the following crash that I would like to reduce > > llc: /home/vadve/aggarwa4/llvm29/llvm-2.9/lib/MC/MCAsmStreamer.cpp:273:

Hi, guys, I am comparing the performance of the default scheduler (seems to be the one that minimizes register pressure) with no scheduler (-pre-RA-sched=none), and I got these numbers. The ratio is low_reg_pressure/none, that is, the lower the number, the better the performance with low register pressure: CFP2000/177.mesa/177.mesa 1.00 CFP2000/179.art/179.art

Hello, Some problems were solved, new ones arised... Getting closer though... The fixes for the previous problems are at the bottom of this email, bug reports will be submitted when all problems are solved. +++ New/remaining problems +++ Currently, 9/26 benchmarks compile and run succesfully. One (fma3d) still has a f95 related problem (see below). The other 16 are divided into two groups:

Kenneth, In general, I am more than happy to help people on this list. It is good for the community and I enjoy helping people be successful

Hi, all I come across the problem when building llvm. The errors are as follows ... etJITInfo&, llvm::JITMemoryManager*, llvm::CodeGenOpt::Level, bool)': : undefined reference to `__register_frame' collect2: ld returned 1 exit status make[2]: *** [/home/lishengmei/llvm-2.6/Release/bin/lli] Error 1 make[2]: Leaving directory `/home/lishengmei/llvm-2.6/tools/lli'
