Hi all, As mentioned in my recent RFC entitled "RFC: a more detailed design for ThinLTO + vcall CFI" I would like to introduce the ability for bitcode files to contain multiple modules. In https://reviews.llvm.org/D24786 I took a step towards that by proposing a change to the module format so that the block info block is stored at the top level. The next step is to think about what the

i'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/doxyge...

...ion passes (opt). An alternative I have is to programmatically generate the corresponding bitcode file at the right time after finishing the pass in discussion - see, for example, http://stackoverflow.com/questions/13903686/writing-module-to-bc-bitcode-file, methods WriteBitcodeToFile() or WriteModule() . Thank you, Alex
