Hi all, I'd like to try rolling a somewhat stripped down and customized CentOS DVD. This is particularly interesting to me now that CentOS 5.5 is 2 DVDs. I dare not call it a new distro as I suspect I will be the only one to use it. ;) I've been googling for ways to do this, figuring it must be somewhat straight forward, but my google-fu is weak it seems. Can someone point me

...malloc instruction raising/lowering pass, you would say > if (MallocInst *MI = dyn_cast<MallocInst>(I)) { Not true at all. Consider the "llvm/IntrinsicInst.h" header, which lets us write stuff like this, today: if (MemCpyInst *MCI = dyn_cast<MemCpyInst>(I)) MCI->getSource() MCI->getLength() ... The one advantage that mallocinst has over using an intrnisic is that instructions can have different return values in various parts of the program (e.g., you can write 'malloc int' instead of '(int*)malloc(4)'). -Chris -- http://llvm.org/ http://non...

Hi Ma, how can I transform the llvm.memcpy into data move loop IR and eliminate > the bitcast instruction ? > I'm not sure why you are concerned about memcpy and bitcasts, but if you call MCpyInst->getSource() and MCpyInst->getDest() it will look through casts and give you the 'true' source/destination. If you want to get rid of memcpy altogether, you can take a look at this pass: https://github.com/seahorn/seahorn/blob/master/lib/Transforms/Scalar/PromoteMemcpy.cc . Best, Kuba On Tue,...

Hi Sanjoy & Hal, Looking at LoopDependenceAnalysis::analyzeZIV ... I don't understand much about SCEV, but the code seems inadequate. Consider these three examples: int a = ...; // we can't be sure of the relationship between a and b int b = ...; // perhaps they are parameters, or the result of I/O for (int i = 0; i < n; i++) { v[a][i] = ...; v[a + 1][i] = ...; } for (int i

I am a student at the University of Alberta under the supervision of José Nelson Amaral, and I have been working on implementing path profiling into LLVM. I have completed my project and would like to submit it. We are looking for a reviewer for the path profiling implementation. We have sent previous requests to the llvmdev list but have so far been unsuccessful. Please see the attached

The pointers must always be i8* the alignment is independent and is controlled by the attributes on the arguments in the call to memcpy. ~Craig On Mon, Jan 29, 2018 at 11:45 PM, ma jun <jun.parser at gmail.com> wrote: > Hi > > > 2018-01-30 15:36 GMT+08:00 ma jun <jun.parser at gmail.com>: > >> Hi >> Thanks ! >> so for this example >>

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the

Hi everybody, I'm currently looking at LLVM as a possible back-end to a dynamic programming system (in the tradition of Smalltalk) we are developing. I have read most of the llvmdev archives, and I'm aware that some things are 'planned' but not implemented yet. We are willing to contribute the code we'll need for our project, but before I can start coding I'll have to

Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:
