similar to: [LLVMdev] Basic Block Frequency counting in LLVM 2.9

Dear All LLVM Users,   I'm new to LLVM environment. I want to perform basic block profiling. I'm using LLVM3.1 I tried it with a simple 'c' code to find Max.No,  mentioned below. ----------------------------------------------------------------------------------------------------------------------------------------- #include <stdio.h> int main() {  unsigned int i,temp;  

I had llvm 2.9 installed on ununtu. I tried to build clang but got following error. I have llvm 2.9 and clang is latest version ( I don't know, I got from svn). I am wondering is it because of version problem ? Does clang work with 2.9 llvm ? llvm[3]: Compiling ClangASTNodesEmitter.cpp for Debug build In file included from

Hello I am new to LLVM and would like to cross-compile LLVM 2.9 on x86 (Ubuntu) to ARM using Code Sourcery LIte toolchain for ARM EABI (2011.03-41). This is the command I used to configure: ./configure --build=i686-pc-linux-gnu --host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi followed by: make -C llvm.2.9 ENABLE_OPTIMIZED=0 I encountered the following errors: configure:error:

Hi All,   Further exploring the problem I could find that, there is a address offset calculation problem, with the GEP bitcast handling code in instruction combining. Below is table which shows address offset calculation for the struct elements (described earlier).   Type Variable Actual Size(in bytes) pass fail llvm2.9 Address(pass) Size-pass (in bytes) Address (fail) Size -fail (in bytes) with

I was building llvm2.9 using MinGW64 on windows, msys was 32 bit so I specified --host option for a cross compiling. Following are my configure options: ../llvm2.9/configure --prefix=/home/AutoESL/llvm-obj --host=x86_64-w64-mingw32 --disable-multilib The error: make[1]: Entering directory `/home/AutoESL/llvm-obj/lib/VMCore' make[1]: ***

I think, finally, I want to conclude on this.   The problem I see is that if I comment the case for "simplificaiton of bitcast to gep of original struct in instruction combining", wherein there is a case for if the offset by which GEP moves the pointer is non-zero.   If I disable this code, then structure elements size, I get is

Hi Pankaj, are you testing this on valid bitcode? The bitcode you sent me did not pass the verifier, i.e. was not valid. Optimizers can be expected to do strange and wrong things if passed invalid bitcode. That is not a bug in LLVM: it is user error if a user doesn't use valid bitcode. Ciao, Duncan. > I think, finally, I want to conclude on this. > The problem I see is that if I

Hello One of our customer is running IRIX 6.5.14 Samba 2.2.1 SGI 3200 with 4 CPU We get continuous error messages on log file kernel oplock not supported Where as as per Irix document this feature is supported from Irix 6.5.2 version Can you please help in enabling this feature ? Will upgrading the samba 2.2.2 will help me in this Thanks and Best Regards Rajendra

Hi, I'm having problems compiling llvm-gcc-4.2-2.9 (from [1]). I need to use this version because I am trying to use KLEE (see [3]) which needs these versions. I am compiling on Arch Linux using gcc (GCC) 4.7.0 20120505 (prerelease) the output of `gcc -v` can be found at http://pastebin.com/8j2m3wzD I have tried the following 1. Extracted llvm-2.9 (from [2]) 2. Applied a patch (adds

Hi, Let say we have a C program, and we want to get pointer to CFG object for this code in order to traverse basic blocks and do some analysis using CFG object. From my main program main.cpp, how can I get pointer to CFG object if argv[1] = hello.c ? I have seen following places among many in clang/lib or clang/include:

Esentially, I'm working on a translator someone started building for llvm2.9 that translates an optimized .lln file to another intermediate language, and I'm porting it to 3.1. There is a new intrinsic that pops up in our test cases' lln files that never used to, llvm.lifetime.start. I looked up the description: "The 'llvm.lifetime.start' intrinsic specifies the start of

With reference to the previous query, I think, i miscalculated the offset, just recalculating. 1. without instruction combining coupling member variable, is at:   %struct._FRAME_DATA* %2, i32 0, i32 5   where "%2" is defined as:   %arrayidx3 = getelementptr inbounds i16* %Data, i32 1024, !dbg !446   %2 = bitcast i16* %arrayidx3 to %struct._FRAME_DATA*, !dbg !446 i.e. at 5 offset in

This fixes a bug in SmallVectorImpl<>::insert, which were not behaving correctly on inserting an empty range into an empty vector: #include <llvm/ADT/SmallVector.h> #include <cassert> int main() { llvm::SmallVector<int, 1> v, w; llvm::SmallVector<int, 1>::iterator it = v.insert(v.end(), w.begin(), w.end()); assert(it == v.end()); } The insert function(s)

Hi, I want to generate Control Flow Graph (in memory CFG object) of any given C program and then iterate over this CFG (all function, basic blocks and instructions) using llvm iterators. I can see text output of CFG on screen, using following command: `clang -cc1 -Idummyh -analyze -analyzer-checker=debug.DumpCFG hello/hello.c' where dummyh has en empty stdio.h to remove this error: `fatal

Hello, (cc:llvmdev Keeping on the list to get more eyes on the problem and for archival purposes). Configure will be re-run, yes. LLVM includes some tools which need to be built for the host, even when cross compiling (e.g., tblgen). In a cross-build, these are built in the BuiltTools directory and that's where you're seeing configure being re-run. >From the below snippet it appears

Hi All,   While collecting type information for "anonymous types", I had below observation.   For the example with anonymous types, given below struct test {   struct {     union {       Char a[4];     };   };   struct {     int b;     char c;   }; };   LLVM 2.6 defines the types as %struct.anon1 = type { %union.anon0} %struct.anon2 = type { i32, i8} %struct.test = type {
