I used the LLVM demo page http://llvm.org/demo/ to generate C++ code for generating LLVM IR code. But that page is now disabled. Is there any tool or other site which does what I'm trying to do, that is I give "C/C++ code" as input and I get the "C++ code for generating the equivalent LLVM IR" as output. -------------- next part -------------- An HTML attachment was

Hello, I am running OS X, when I build clang++ from source and use it to compile .cpp files it fails as it is not able to find C++ header. I am not building libc++ along with llvm and clang. using -stdlib=libstdc++ solves problem partially but it fails when using C++11 threads, again it can't find <thread>, to get this work clang++ should work with -stdlib=libc++ but it fails with

Hi, I know using llc i can print machine code (-print-machineinstrs). How can i print machine code using llvm c++ api.. i looked into llc code but not able to find it.. Thanks & Regards, Pachauri

Hi Vivek, you can also include these lines below to your ~/.bash_profile: LLVM_BUILD="/Developer/llvm/build" # Path to your build directory alias new-clang="$LLVM_BUILD/bin/clang -Wno-expansion-to-defined -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include" alias new-clang++="$LLVM_BUILD/bin/clang++

-disable-O0-optnone has no effect with anything other than -O0. -O0 being passed to clang also causes all functions to be marked noinline. I don't know if there is a command line option to turn that off. I recommend passing "-O1 -Xclang -disable-llvm-passes" to clang. Passing -O0 very specifically means disable optimizations. ~Craig On Sat, Jan 6, 2018 at 12:25 PM, toddy wang

Why are you using build directions from "flang" which is a fortran compiler and maintained by different people than the LLVM/clang community? But then compiling C/C++ code? Their bug database should be used for filing bugs against the fortran compiler not a C/C++ compiler issue. ~Craig On Sat, Jan 6, 2018 at 1:04 PM, toddy wang <wenwangtoddy at gmail.com> wrote: > Thanks a

clang++ generates invalid code for on-stack struct compares with overloaded operators in release 3.0. Take the following code: struct A { bool operator<(const A& other) { return ((long long int)this) < ((long long int)&other); } }; int main() { A a, b; return (a < b) + (b < a); } Usually, this program should return 1. Compiling it with "clang++ -Ox" with x

@Craig and @Michael After installing clang-5.0 (download from http://releases.llvm.org, does not have Flang build's slowdown mention above), 1. clang++ -O0 -Xclang -disable-O0-optnone -Xclang -disable-llvm-passes -c -emit-llvm -o a.bc LULESH.cc; opt -O3 a.bc -o b.bc; llc -O3 -filetype=obj b.bc -o b.o ; clang++ b.o -o b.out; ./b.out 20 runtime: 2.354069e+01 2. clang++ -O1 -Xclang

Thanks a lot, it is clear to me now. BTW, for Clang's slowdown, I submit an issue here: https://github.com/flang-compiler/flang/issues/356 I have no idea about the root cause. Maybe due to debug symbols. But, I already use -DCMAKE_BUILD_TYPE=Release. Anyway, I believe there is a bug somewhere.

@Zhaopei, thanks for the clarification. @Craig and @Michael, for clang 4.0.1, -Xclang -disable-O0-optnone gives the following error message. From which version -disable-O0-optnone gets supported?

Hi, I'm really a novice in experimenting with LLVM, so I might be doing something plain wrong here, but I can't understand why this snippet // File ticket.cpp struct ticket { int field1; char field2[10]; } _ticket; goes fine through the sequence 1) clang++ -O0 -S -emit-llvm ticket.cpp (which generates ticket.s) 2) llc -march=cpp ticket.s So that I end up with a ticket.s.cpp that I
