From d3be62ddf2eb1cfba957f1bbcea28eef9806479e Mon Sep 17 00:00:00 2001 From: "Duncan P. N. Exon Smith" Date: Sun, 27 Mar 2016 22:45:25 +0000 Subject: Bitcode: Add SimpleBitstreamCursor::getPointerToByte, etc. Add API to SimpleBitstreamCursor to allow users to translate between byte addresses and pointers. - jumpToPointer: move the bit position to a particular pointer. - getPointerToByte: get the pointer for a particular byte. - getPointerToBit: get the pointer for the byte of the current bit. - getCurrentByteNo: convenience function for assertions and tests. Mainly adds unit tests (getPointerToBit/Byte already has a use), but also preparation for eventually using jumpToPointer. llvm-svn: 264546 --- llvm/lib/Bitcode/Reader/BitstreamReader.cpp | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'llvm/lib/Bitcode') diff --git a/llvm/lib/Bitcode/Reader/BitstreamReader.cpp b/llvm/lib/Bitcode/Reader/BitstreamReader.cpp index af489d75011..fe3f6e8b59a 100644 --- a/llvm/lib/Bitcode/Reader/BitstreamReader.cpp +++ b/llvm/lib/Bitcode/Reader/BitstreamReader.cpp @@ -261,9 +261,7 @@ unsigned BitstreamCursor::readRecord(unsigned AbbrevID, } // Otherwise, inform the streamer that we need these bytes in memory. - const char *Ptr = - (const char *)getBitStreamReader()->getBitcodeBytes().getPointer( - CurBitPos / 8, NumElts); + const char *Ptr = (const char *)getPointerToBit(CurBitPos, NumElts); // If we can return a reference to the data, do so to avoid copying it. if (Blob) { -- cgit v1.2.3
