2011-07-09fix a really bad bug that would cause nested cursors to break,Chris Lattner
used by the new bitcode reader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134821 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-25Enhance the sanity check for block sizes; check that the resulting pointer isNick Lewycky
pointing to the range [first character, last character] instead of just not after the last character. Patch by Yan Ivnitskiy! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133867 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-27Clean up the minor mess I caused with removing iterator.h. I shall take care ↵Gabor Greif
of 80-col violations and the FIXME later. (Thanks goodness that I live in another continent, so the monkeypox did not strike me :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80224 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-07fix some type confusion in ReadVBR64: "Piece" should be only 32 bits,Chris Lattner
not 64, because we read at most 32 bits at a time. OTOH, "Result" must be 64-bits and insertion into it must be 64-bit clean. Thanks to Ivan Sorokin for bringing this up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74932 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-29Fix three MSVC 2008 warnings that completely clutter the build output.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74430 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-27give bitstreamreader an API to ignore names for blocks/records,Chris Lattner
only llvm-bcanalyzer wants this info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70239 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Add two new record types to the blockinfo block:Chris Lattner
BLOCKNAME and SETRECORDNAME. This allows a bitcode file to be self describing with pretty names for records and blocks in addition to numbers. This enhances llvm-bcanalyzer to use this to print prettily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70165 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26make BitstreamCursor's copyable and assignable.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70159 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Make a major API change to BitstreamReader: split all the readingChris Lattner
state out of the BitstreamReader class into a BitstreamCursor class. Doing this allows the client to have multiple cursors into the same file, each with potentially different live block stacks and abbreviation records. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70157 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-08Fix BitstreamReader's GetCurrentBitNo to return the correct bit number, and ↵Douglas Gregor
stop JumpToBit from covering up its mistakes git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68648 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Add an API for the bitstream reader to read blobs and returnChris Lattner
them by reference, instead of packing each byte into a smallvector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68486 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-06allow clients to look up abbrev id'sChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68471 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-06add a new Blob encoding abbreviation for bitcode files that emitsChris Lattner
elements in a form that is efficient for the reader to just get a pointer in memory and start reading. APIs to do efficient reading and writing are still todo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68465 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68463 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-01Use CHAR_BIT instead of hard-coding 8 in several places where itDan Gohman
is appropriate. This helps visually differentiate host-oriented calculations from target-oriented calculations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68227 91177308-0d34-0410-b5e6-96231b3b80d8

discussion of this change. Boy are my fingers tired. ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45411 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-10Made Deserializer a friend class of BitstreamReader.Ted Kremenek
Moved some of the logic in BitstreamReader::ExitBlock into a utility function BitstreamReader::PopBlockScope. The latter is a private method. It will also be called by Deserializer to manipulate the current "block scope." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43972 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-05Implement support for globally associating abbrevs with block IDs, whichChris Lattner
relieves us from having to emit the abbrevs into each instance of the block. This shrinks kc.bit from 3368K to 3333K, but will be a more significant win once instructions are abbreviated.
