similar to: Crash using exceptions

I am new to llvm so I might be missing a critical step. My system is Fedora 12 but this also happens in Mac OS X 10.6.2. Here are the steps I used to compile llvm: export TARGETS=x86,x86_64,cpp export INSTALLDIR=/home/rovitotv/llvm ../llvm-2.6/configure --prefix=$INSTALLDIR --enable-bindings=none --enable-targets=$TARGETS --enable-optimized --with-llvmgccdir=$INSTALLDIR

First, you have to call llvm-g++ to use the llvm-gcc front end, but it doesn't matter here. I'd like to suggest that you use pastebin to put your code and the send us the link, so that we can download it. The problem is that TheExecutionEngine is set to NULL (maybe because of a previous error), but it will be really better if you use pastebin. On Wed, Feb 17, 2010 at 6:01 AM, Todd Rovito

Hello all, When extending the tutorial to support global variables I'm getting the following linker error: glob.o:glob.cpp:(.text+0x12241): undefined reference to `vtable for GlobalExprAST' collect2: ld returned 1 exit status GlobalExprAST class is: /// GlobalExprAST - Expression class for globals class GlobalExprAST : public ExprAST { std::string Name; ExprAST *Init; public:

Firstly, apologies if this is not the right place to be asking this question--feel free to point me in the correct direction. I could be doing something wrong here but stackoverflow didn't feel like the correct place for this since there's so little there about LLVM ORC. Basically, I have a reproduction case (below) where if I throw an exception before I call JITSymbol::getAddress()

Hi David, This looks like bad eh-frame data due to a failure to fix up the frame descriptor entries: <debug: adding frame> EHFrameAddr: 0x7feae5827000, EHFrameLoadAddr: 0x00000000e5827000, EHFrameSize: 60 ==64588==ERROR: AddressSanitizer: SEGV on unknown address 0x7feae5827020 (pc 0x7feae886d970 bp 0x000000000001 sp 0x7ffca10e75f8 T0) Eyeballing the code in RuntimeDyldELF (vs

Hi David, Thanks very much for that. I'll continue to dig in as time permits, and I'll update the bug report with my progress once it's filed. Cheers, Lang.

Hi David, Sorry to hear. Has anyone followed up with you yet? I've continued to dig in to this in my spare time and I've found the issue. It's a use-after-free, rather than any sort of memory smashing. ORC is currently failing to deregister the EH-frame section when the JIT is torn down (but *is* deallocating the memory for it). Normally that's not disastrous (though it does

Very nice. Here's a couple comments on the first 6 chapters: http://llvm.org/docs/tutorial/LangImpl1.html "We handle comments by skipping to the end of the line and then returning the next comment." Shouldn't this say "returning the next comment"? http://llvm.org/docs/tutorial/LangImpl2.html I was a bit confused at first because the AST node classes are called ASTs.

I've actually tried to compile both LLVM and my lib with -frtti with same results.

+ MLIR dev mailing list since that’s where the OrcJit I’m using is. Thanks for all the details, Lang! What you described is exactly what I’m looking for! Please, MLIR dev, let me know if this debug feature and the solution that Lang describes below is interesting for MLIR. I’ll dig more into the details then but it doesn’t seem too complicated. Thanks, Diego From: Lang Hames [mailto:lhames at

I didn't seen any roadmap and plan about OrcJit & MCJIT. And would OrcJIT be stablize in version 7.0? Or latter version? Would MCJIT be removed in source tree, when? -- 此致 礼 罗勇刚 Yours sincerely, Yonggang Luo -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello everyone A previous thread about OrcJIT brought up bug reports on Bugzilla. A quick search gives 20+ results: https://bugs.llvm.org/buglist.cgi?component=OrcJIT&list_id=162232&query_format=advanced&resolution=--- While some of them are obviously outdated (addModuleSet API cleanup [1]), others may actually be relevant again (Small code model? [2]). If you reported one of them,

Hi, I'm incrementing my toy compiler to account for variable mutations around if/else blocks. Reading the Kaleidoscope tutorial, I've learnt that I can substitute the PHI node creation by allocas and retrieving the value later, if needed. The Kaleidoscope example seems to account for one value only, the result of: Value *ThenV = Then->Codegen(); (...) Value *ElseV =
