emitDarwinBCHeaderAndTrailer()

static void emitDarwinBCHeaderAndTrailer ( SmallVectorImpl< char > &  Buffer, const Triple &  TT  )

static

If generating a bc file on darwin, we have to emit a header and trailer to make it compatible with the system archiver.

To do this we emit the following header, and then emit a trailer that pads the file out to be a multiple of 16 bytes.

struct bc_header { uint32_t Magic; // 0x0B17C0DE uint32_t Version; // Version, currently always 0. uint32_t BitcodeOffset; // Offset to traditional bitcode file. uint32_t BitcodeSize; // Size of traditional bitcode file. uint32_t CPUType; // CPU specifier. ... potentially more later ... };
