similar to: [LLVMdev] Linking an opt optimization pass to clang?

Hi I am not sure if it is possible to do something similar to what the LLVM pass framework offers (via the opt program) but in the JIT instead (when running lli). Is it possible to do any kind of online profiling (or optimization) of dynamically compiler code similar to writing an opt style code pass module? Or would I have to change a lot of stuff in the JIT? Thanks -Puyan

>From a cached version of the Getting Started Guide, I have found: "GCC 3.4.4 (CodeSourcery ARM 2005q3-2): this compiler miscompiles LLVM when building with optimizations enabled. It appears to work with "make ENABLE_OPTIMIZED=1 OPTIMIZE_OPTION=-O1" or build a debug build." I'm trying that now. -Puyan On Sun, Feb 21, 2010 at 1:22 AM, Rajika Kumarasiri <rajika at

Puyan, There is a doc on the document page which describe the list of broken GCCs. You'll need to check it once the docs are online.

Specifying --host, --build and --target should work. For example, $ configure --host=arm-apple-darwin10 --build=i686-apple-darwin10 --target=arm-apple-darwin10 --enable-targets=arm -Jim On Feb 17, 2010, at 12:26 PM, Puyan Lotfi wrote: > Does anyone know what I should be doing if I want to cross compile LLVM for the ARM architecture? > I want to use the LLVM JIT on ARM for a class

Hi Does there exist a list of relative compile times for source files in LLVM? I am doing a build for ARM on an actual ARM device, and CodeGenDAGPatterns.cpp is taking a really long time to compile (it's been like 20 minutes or more). I don't even get an error. All the files before it compile pretty quickly but this file in particular just won't finish. The version of gcc I have on

Does anyone know what I should be doing if I want to cross compile LLVM for the ARM architecture? I want to use the LLVM JIT on ARM for a class project this semester. I have built and/or installed a few different gcc arm (arm-linux, and also one that is arm-elf) toolchains, and have had trouble getting LLVM 2.6 to configure and compile using the --host and --build switches of the config. If there

Hi, I’d like to run clang with some optimization passes (-reassociate, -simplifycfg, -dce ) But in the end I need to dump the llvm IR (no link to assembly generation). I didn’t find any way to do that. I found out that passes are run via opt, but opt generates bc code, and I want IR. Any help will be welcome Thanks, Régis -------------- next part

Dear Friends, I need to pass an option to an llvm analysis pass through clang and dragonegg, to llvm's opt. Right now opt takes the flag, but when I pass the flag through clang with -mllvm, I get an error. I am trying to figure out how other options are passed to llvm through clang (as suggested in the mailing list). But if someone has more inputs on how to do this (also with dragonegg), it

Hi Eli, I have tried that: static void registerMyPass(const PassManagerBuilder &, llvm::legacy::PassManagerBase &PM) { PM.add(new MyPass()); } static RegisterStandardPasses RegisterMyPass(PassManagerBuilder::EP_OptimizerLast, registerMyPass); It still couldn't find my pass. Regards, Soham Sinha PhD Student,

You are calling the option -auto-profile in some places and -fauto-profile in others. Maybe it is just a typo?

Hello, I have written a pass for the IR and I can run it with opt -load lib/LLVMMyPass.so -mypass -myarguments -S -o output.ll < output.bc I have registered my pass with the following code: static RegisterPass<MyPass> X("mypass", "MyPass Pass (with getAnalysisUsage implemented)"); How do I include the same pass in the clang driver. I tried running the pass: clang

I'm trying to add a new option to clang to enable my auto profile pass. I've added this to Options.td and Driver/Tools.cpp, but I'm not getting the option -auto-profile in cc1's invocation. I've checked that the code to push -auto-profile is executed, but if use -v, I don't see -auto-profile in the cc1 invocation. Can anyone point me to some document that explains how to

I have tried to invoke a transformation/optimization pass using -mllvm, without success. I might be missing something. For example I have a shared/dynamic library which contains LLVM passes. I used to invoke them with llvmc like this: >>*llvmc mycode.c -o mycode.o -c -opt -Wo,=-load,libFoo.dylib,-Foo* Can this style of optimization be executed using -mllvm argument? Thx, PMon On Sun,

Hey all, I need to use C bindings in a pass that I am authoring (specifically, I want to use the OCaml bindings that are tied to the C bindings to author the pass). However, this requires that I link in LLVMCore to provide said bindings to my library. From what I've read, there is a known issue with linking LLVMCore into a module that is fed to opt. Namely, you get the following assertion:

Hi all, I would like to know which optimization passes are performed at -O2 by opt. So I used following command: llvm-as < /dev/null | opt -O2 -std-compile-opts -disable-output -debug-pass=Arguments I've got following output for LLVM opt 2.9: Pass Arguments: -no-aa -tbaa -basicaa -simplifycfg -domtree -scalarrepl -early-cse Pass Arguments: -targetlibinfo -no-aa -tbaa -basicaa

what is the solution to pass opt arguments , non ordinary passes like : *-std-link-opts* by clang ? Dose clang invoke opt in normal compilation procedure even? -- View this message in context: http://llvm.1065342.n5.nabble.com/Passing-arguments-to-opt-via-clang-tp3161p58920.html Sent from the LLVM - Dev mailing list archive at Nabble.com.

No. You cannot add additional passes this way, only pass 'ordinary' arguments. -- With best regards, Anton
