Thank you all for your reply. if(a>10) b=10; else if (a<10) b = 5; Here is the IR of the if-elseif: 56 %0 = load i32, i32* %a, align 4 57 %cmp = icmp sgt i32 %0, 10 58 br i1 %cmp, label %if.then, label %if.else 60 if.then: ; preds = %entry 61 store i32 10, i32* %b, align 4 62 br label %if.end.4 63 64 if.else:

After converting a piece of C++ code to C one of the functions that are generated is this: _ZStlsISt11char_traitsIcEERSt13basic_ostreamIcT_ES5_PKc Where is it defined and where can I find the source for it? I need the source to compile it with a C compiler (AMPC) that will convert the C code to Java Bytecode. If the above function is in C++ then I need to convert it to C first. Here's the

hi, I try to build hello.cpp using both llvmg++ and GNU g++, the generate llvm bytecode's size is about 960K, and the size of binary code generated by g++ is only 13K. Could anyone explain the difference between the two result? BWT: I rebuild the cfrontend in RH linux9.0, but when I build the hello.cpp the llvmG++ reports warnings too, it shows: ----------------------------- [yue at RH9

Report by Eric Lindblad 28-08-2015 http://www.ericlindblad.blogspot.com As of Windows 8.1 MS has discontinued enabling for Interix, so perhaps there is little or no interest in this e-mail's subject matter. NB: As far as possible languages for xapian-bindings I only have be able to compile earlier versions of Tcl with a static library on Interix 3.5, Perl versions fail 'make check',

Question by Eric Lindblad 05-09-2015 http://www.ericlindblad.blogspot.com I would enquire if anyone has an opinion on whether it might be a possibility that adding the following #ifdef in certain xapian-core-1.2.21 /common and/or /backends files following the string #include <sys/types.h> might move closer towards resolution the 'ambiguous overload' issue. +#ifdef __INTERIX +#

What I'm saying is that it appears that your implementation of operator<< is not functional or is missing. You said that you are using GCC on internix. Is it possible

No, Chris, I'm not buying that argument, due to I've tweaked /usr/include/types.h a little bit, so the configuration and compilation of the cfrontend would be correct: /* * 64bit type for BSD compatability */ #ifdef __GNUC__ typedef long long int quad_t; typedef unsigned long long int u_quad_t; typedef long long int int64_t; typedef unsigned long long int u_int64_t;

Yes, Chris you're right. It seems that my << operator for int64_t is missing in my '/opt/gcc.3.3/include/c++/3.3/bits/ostream.tcc' file. Which ordinary version of GCC are you working with and how do your definition of the << operator for int64_t look like? /Henrik > >Here is an excerpt from the config.log for LLVM: > >configure:19451: checking for int64_t

hi, i also have problems compiling llvm-gcc (current svn version). llvm is current llvm svn. i tried to use every gcc version from 4.0 to 4.3 to compile llvm-gcc. i configured llvm-gcc like this (and tried every other combination of disable-shared, disable-multilib and bootstrap) : ../llvm-gcc/configure --prefix=/usr --enable-llvm=/usr --enable-languages=c,c++ --disable-shared

I'll ask again that question. Thank you Adrian, I've looked through IR Verifier and it helps me to understand some parts of retrieving metadata and debug info. But , after that, I've faced with another problem: Original Code: std::wcout << L"WCHAR_HELLOWORLD" << std::endl;b IR Code: @.str.2 = private unnamed_addr constant [17 x i32] [i32 87, i32 67, i32 72,

Hello friends working on LLVM, I am a beginner to LLVM. I tried to get C code from LLVM bitcode using 'llc -march=c'. But it seems to me that it doesn't work if the source program is a C++ program. Am I right? I have attatched the source program and the result of compiling the C code of it with GCC4.3.3. By the way, has LLVM's C code backend been tested on benchmarks like spec?

You can link it in at the bytecode level with: llvm-g++ -o output.bc <yourfile.bc> -lstdc++ You might also be able to do: llvm-g++

I’ve missed the discussions on file_time_type, however I thought I should throw in my opinion here before it is too late to do anything about it. I believe it is a mistake to model file_time_type with 128 bits. It
