Duncan P. N. Exon Smith d7084fcebd Bitcode: Collect all MDString records into a single blob ... Optimize output of MDStrings in bitcode. This emits them in big blocks (currently 1024) in a pair of records: - BULK_STRING_SIZES: the sizes of the strings in the block, and - BULK_STRING_DATA: a single blob, which is the concatenation of all the strings. Inspired by Mehdi's similar patch, http://reviews.llvm.org/D18342, this should (a) slightly reduce bitcode size, since there is less record overhead, and (b) greatly improve reading speed, since blobs are super cheap to deserialize. I needed to add support for blobs to streaming input to get the test suite passing. - StreamingMemoryObject::getPointer reads ahead and returns the address of the blob. - To avoid a possible reallocation of StreamingMemoryObject::Bytes, BitstreamCursor::readRecord needs to move the call to JumpToEnd forward so that getPointer is the last bitstream operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@264409 91177308-0d34-0410-b5e6-96231b3b80d8		2016-03-25 14:40:18 +00:00
