...least this combination passed the previously failed step, but got stuck in later ones. Also my GCC is still 4.5, so llvm 3.0 is not that outdated?

...to LLVM3.0 because it uses the new TargetTransformInfo analysis. I also wanted to mention that only _lowering_ passes (target-specific optimization passes) may use TTI and the cost model. Higher-level canonicalization passes should not use it.

Hi All, I wanted to do some basic cost estimation of Instruction/BB. There're CostModelAnalysis and CodeMetrics available in 3.1 and 3.2 releases. I've been using 3.0 for a while. I'm wondering whether similar analysis can be done in the old 3.0 release, e.g. back porting the implementation. Thank you! Best, Ryan -------------- next part -------------- An HTML attachment was

Thanks for replying! I didn't install the new binutils to system directory in case it messes thing up. For ranlib, from the error message, it seems to be the reason. But even I export RANLIB=/bin/true, clean the code and rebuild, it still fails with the same message. I created a symlink in /usr/lib/bfd-plugins as suggested in http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-March/030101.html.

Hi All, This is encountered when compiling llvm-gcc-4.2 (yeah, it's deprecated, but still want to play with it :)). I compiled an old gcc(4.2.1) in my home directory and set the bin to PATH to work with it. llvm-gcc compilation failed with the following: llvm-gcc/obj/./gcc/cc1: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found. So seems it didn't try to search the library

Hi, This question may be bit dumb. But I couldn't find it in the doc. Can I call instantiated a Pass and call methods like runOnFunction on a single Function object that I want to look at ? Or I have to use opt and then loop until that function? Thanks Ryan -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi All, Looking at the code of MemDepPrinter.cpp, I saw the char MemDepPrinter::ID = 0; > INITIALIZE_PASS_BEGIN(MemDepPrinter, "print-memdeps", > "Print MemDeps of function", false, true) > INITIALIZE_PASS_DEPENDENCY(MemoryDependenceAnalysis) > INITIALIZE_PASS_END(MemDepPrinter, "print-memdeps", > "Print MemDeps of function", false, true)

Hi, When I tried to compile Dragonegg using the SVN trunk code, I encountered failure with error message: In file included from > /usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5.2/plugin/include/rtl.h:28:0, > from /home/xxx/llvm/dragonegg/src/Convert.cpp:63: > /usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5.2/plugin/include/real.h:27:18: > fatal error: mpfr.h: No such

Yest. thanks. I just resolved this error by installing MPFR, MPC and GMP(by the way, these are not listed as prerequisites in the website.). But other errors come: /home/xxx/llvm/tools/dragonegg/src/TypeConversion.cpp: In function > ‘llvm::FunctionType* ConvertArgListToFnType(tree_node*, > llvm::ArrayRef<tree_node*>, tree_node*, bool, llvm::CallingConv::ID&, >

Hi, I build llvm with gold plugin, clang and the binutils(and it's put into the PATH) with plugins support. ld.gold is renamed to ld. A quick test of clang -flto -O0 hello.c can succeed. But when I try to export CC="clang -v -flto" and compile MySQL, it failed in the linking with the following error message: "/home/ryan/binutils/bin/ld" -export-dynamic -z relro
