...9;m afraid this question is extremely basic, but i've assumed that dumping a .bc file from a module was a trivial operation, but now, first time i have to actually do it from code, for the life of me i can't find one missing step in the process: static void WriteModule ( const Module * M, BitstreamWriter & Stream ) http://llvm.org/docs/doxygen/html/BitcodeWriter_8cpp.html#a828cec7a8fed9d232556420efef7ae89 to write that module, first i need a BistreamWriter BitstreamWriter::BitstreamWriter (SmallVectorImpl< char > &O) http://llvm.org/docs/doxygen/html/classllvm_1_1BitstreamWriter.ht...

Hi all, I've been looking into how to make llvm bitcode files smaller. There is one simple change that appears to shrink linked bitcode files by about 15%. See this spreadsheet for some rough data: https://docs.google.com/spreadsheet/ccc?key=0AjRrJHQc4_bddEtJdjdIek5fMDdIdFFIZldZXzdWa0E The change is in how operand ids are encoded in bitcode files. Rather than use an "absolute

I am currently making some BitcodeWriter changes that involve some refactoring, and am thinking for the Nth time that it would be much nicer to have a class instead of passing around a long list of parameters. I am thinking of biting the bullet and doing that - any objections? I assume the reason why there is no existing class wrapping the bitcode writing process is just legacy code and nothing

Thanks for that. Yes, I see what you mean (no Mach-O envelope), yet there seems to be something

Hi all, We're hitting some walls here when generating the correct structure layout for specific C++ ABI requirements, and I was wondering how much StructLayout could help. For instance, the ABI has some complicated rules on the size of derived classes (http://www.codesourcery.com/public/cxx-abi/abi.html#class-types) and LLVM struct type cannot reflect that in full. Example: // CHECK:

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel
