Now I have an address that present in a unsigned long address like the following format: Value* addr = CONST(0xc0008000) But I do not know how to read the data from the above addr varaible. I tried the following three kind of code: 1. Code: Value* addr = CONST(0xc0008000); Value* data = new LoadInst(addr, "", false, bb); Error: Segmentation fault 2. Code(

Hi Michael, > Now I have an address that present in a unsigned long address like the > following format: > Value* addr = CONST(0xc0008000) what is the type of addr?

Hi Matthijs, Yes, I've turned off the link-time optimizations (otherwise it just propagates my constant vectors and immediate prints the result). :-) Here's essentially what I try to generate: void add(float z[4], float x[4], float y[4]) { z[0] = x[0] + y[0]; z[1] = x[1] + y[1]; z[2] = x[2] + y[2]; z[3] = x[3] + y[3]; } And here's part of the output from the online

llvm does not automatically vectorize your scalar code (as least for now). You have to write gcc generic vector code or use vector builtins.

I have a value of long type and like to get the data at the adress in the value: ################# unsigned long v = 0xc0008000 Value* addr = ConstantInt::get(getIntegerType(64), v) #################### Then I try to use LoadInstr to get a load instruction of ir as the following: ############################ Value* data = new LoadInst(addr, "", false, bb); encounter segmentation

Hello, I'm trying to translate part of Java code in LLVM code. I have some problems with the "opaque type", I think because I did not understand how to use. So, the java code is: int[] ai; .... ai = new int[1]; I am using LLVM API in this way: //I create a pointer of Opaque type, because I don't know yet the array size! OpaqueType* ot = OpaqueType::get(); AllocaInst*

Greetings, LLVM wizards. I am using clang to compile a C++ module, and an ExecutionEngine (MCJIT) to execute a function it defines. That works (or pretends to). However, if I call the module's constructors first: exec_engine->runStaticConstructorsDestructors(false); exec_engine->runFunctionAsMain(function, argvec, NULL); execution still works, but my program crashes when it exits, in

Hi, everyone: I am very sorry to trouble you, but I need your help about my problem about ThreadLocalImpl in llvm of 2.8 version. I have compiled it in Windows xp with mingw, and have compiled skyeye(an open source project about simulator) as it uses llvm. But when I run a testcase ---- arm_hello, it came out segment fault. I used gdb.exe to trace it, it gave the following infomation: $

Hi, > I am very sorry to trouble you, but I need your help about my problem about > ThreadLocalImpl in llvm of 2.8 version. this is a very old version of LLVM, I suggest you try something newer, eg the recently released version 3.1.

On Alex's advice I am switching from MCJIT to the Orc API to compile and execute functions. Starting from the new clang-interpreter example in the source code (top of the tree!), I am able to execute my functions all right... as long as there are no constructors and destructors to call. My question: is there a simple way, with the Orc API, to run a module's constructors and destructors? I

When OrcMCJITReplacement is given a new module, it asks for the module's constructors, gives them names like $static_ctor.0, $static_ctor.1, etc., and saves the mangled names in a map. Later, to execute them, it uses runViaLayer(), which looks for those symbol names in the given JIT layer. Could one not simply execute the constructors straight away, rather than naming them and looking them up

Hi, guys. I'm a newbie to LLVM and have a very simple question. Which instructions should I use (in terms of IRBuilder calls) to allocate an array of bytes in stack (alloca?), then to work with it (from a given offset) as with integer (bitcast?). I mean something like that: unsigned char var[8]; unsigned int offset = 3; int val = *(int*)(&var+offset); /* read */ *(int*)(&var+offset)

Hi Evan, Please note that I'm not trying to compile from C code, I try to generate functions at run-time directly. I want to keep it target-independent too, so I can't use intrinsics either.

Many thanks for the sample code, Alex. In the end I did it the same way OrcMCJITReplacement does it. Constructors and destructors are called and, thanks to LocalCXXRuntimeOverrides, the program does not crash on exit! But it does seem like there should be a simpler way; the learning curve is steep... Geoff On Thu, 21 Jun 2018 at 12:28, Alex Denisov <1101.debian at gmail.com> wrote: >

hi all please could u help me in these points 1- I have installed llvm-gcc 4.2 and llvm 2.8 with the synaptic package manager(ubuntu 10.10) every time i do this commande: llvm-gcc -O3 -emit-llvm hello.c -c -o hello.bc it shows to me i should install llvm-gcc4.5 when i have installed llvm-gcc 4.5 i get all the times a wrong bc file as output, because when i try to execute it with lli it says to me
