Reid Spencer 2807accdc5 Bytecode Analyzer Cleanup:
- Rearrange output order to make more sense
- Make only the function level output count as "detailed"
- Output dump output directly to stream, don't buffer it.
- Fix counting of block sizes
- Implement new handlers for number of types, dependent libs, target triple
- Compute the size of block headers.

Reid Spencer 6639333f20 Two Changes:
- Pass the output stream to the analyzer so it can write its output there
  directly instead of buffering it.
- Don't pass a boolean to ParseBytecode because its not needed any more.

Reid Spencer 8631bc3aaa Add boolean file format flags in preparation for version 5 bytecode.
Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions

Reid Spencer 191aa30ac1 Bytecode Reader Cleanup:
- provide the correct conversion for ModuleBlockID in read_block (a potential
  bug but not actually exploited because reading module block ids doesn't
  use read_block).
- install support for handleTypeList handler
- install support for handleDependentLibrary handler
- install support for handleTargetTriple handler
- clean up comments, output strings,
- ensure that processing function arguments doesn't SIGSEGV if one of the
  arguments is a null pointer (yeah, it happened .. weird)
- prepare for version 5 bytecode by documenting what will change.

Chris Lattner 74635dc879 Fix a serious bug in the double constant reader. In particular, because
(At[3] << 24) is an int type and it is being coerced to uint64_t, it was
getting sign extended, causing us to get FFFFFFFFxxxxxxxx constants all of
the time.

Reid Spencer b2bdb943b5 bug 263:
- encode/decode target triple and dependent libraries
bug 401:
- fix encoding/decoding of FP values to be little-endian only
bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
  in multiples of 64KByte chunks rather than in multiples of some smaller
  (default) number.

Reid Spencer 194c576efc Various cleanups:
- Remove tabs
- Standardize use of space around ( and ).
- Consolidate the ConstantPlaceHolder class
- Rename two methods to be more meaningful (ParseType, ParseTypes)
- Correct indentation of blocks
- Add documentation
- Convert input dependent asserts to error(...) so it throws instead.
Provide placeholder implementations of read_float and read_double that
still read in platform-specific endianess. When I figure out how to do
this without knowing the endianess of the platform, it will get implemented
correctly.

Reid Spencer f3905c8511 Error Handling Cleanup:
- get rid of PARSE_ERROR macro
- add error(std::string) function
- use error(std::string) for all errors
- make input dependent asserts call error(std::string) instead
- ensure asserts are only for logic bugs, not input discrepancies.

2004-07-09 22:21:33 +00:00
Reid Spencer 6a218134e3 Fix a backwards compatibility bug found by Tanya. In version 1.2, the
global type plane starts with a length and the TypeTyID value to identify
the type plane has having type definitions. This doesn't happen in 1.3
because the types are read from a known position in the file. However, the
TypeTyID must be read in (and ignored) if its a 1.2 bytecode file.

Reid Spencer 02b6708e01 Finalize bytecode dumping. The "handleFinish" method was getting called
too soon so the function data was not getting dumped (it was generated

Reid Spencer bc70f74825 - Don't use macros to call the BytecodeHandler
- Don't use PARSE_ERROR macro unnecessarily (for simple strings)
- Add comments before each function
- Convert for bug 122 (Type != Value)
- Handle new value range on Type::PrimitiveTypeId enumeration by augmenting
  the reader with a new read_typeid method and sanitizeTypeId method.
- Remove BytecodeHandler's default method implementations to header file.

Reid Spencer fddebf7ff2 Remove files no longer needed. ConstantReader and InstructionReader were
integrated into Reader. Parser.* was just a bad idea. AnalyzerInternals.h
is no longer needed. ReaderPrimitives.h was integrated into Reader.h and
Reader.cpp. Dumper.cpp was integrated into Analyzer.cpp. ReaderInternals.h

ReaderWrappers.cpp

Reid Spencer 284b7c7174 MAJOR REWRITE.
- stop passing Buf/BufEnd to every function (now member vars)
- internalize things that used to be in a header file that no one else
  included/needed.
- Remove defunct BCR_TRACE lines
- Standardize error handling with the PARSE_ERROR macro.
- Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize
  the definition order so that gcc has a chance at optimizing this module
- Standardize case and style of method names.
- Eliminate unneeded header files
- Prepare for Type != Value (bug122) change by splitting Types into their
  own data structures.
- Implement the BytecodeHandler interface calls.
- Provide default implementation of BytecodeHandler interface.

Reid Spencer 42427f0ccb Fix the bug that was preventing the parser from working on all bytecode
files. It was reading non-initialized global vars when the flag said it was
initialized and vice versa. Causes mis-alignment since initialized and
non-initialized constants have different bytecode lengths.

Reid Spencer fbe659d435 Merged BytecodeHandler.h into Parser.h since the parser and the handler

2004-06-08 05:51:18 +00:00
Reid Spencer db5c86d0b1 Commit For New Tool: llvm-abcd (Analysis of ByteCode Dumper). This tool
will (eventually) provide statistical analysis of bytecode files as well
as the ability to dump them in a low level format (slot numbers not
resolved). The purpose of this is to aid in the Type!=Value change of
bug 122. With this initial release, llvm-abcd merely dumps out the
bytecode. However, the infrastructure for separating bytecode parsing from
handling the parsing events is in place. The style chosen is similar to
SAX XML parsing where a handler object is called to handlign the parsing
events. This probably isn't useful to anyone but me right now as there is
no analysis yet, and the dumper doesn't work on every bytecode file. It
will probably be useful by the end of this week. Note that there is some
duplication of code from the bytecode reader.  This was done to eliminate
errors from being introduced in the reader and to minimize the impact to
other LLVM developers. At some point, the Analyzer and the Reader will be
integrated to use the same infrastructure. Also, sorry for the minor change
to Instruction.h but I just couldn't bring myself to write code that
depends on Instruction internals.

2004-01-18 22:35:34 +00:00
Chris Lattner e104d88f83 Add support for reading bytecode files with compactiontables for bytecode files.
This shrinks the bytecode file for 176.gcc by about 200K (10%), and 254.gap by
about 167K, a 25% reduction.  There is still a lot of room for improvement in
the encoding of the compaction table.

Chris Lattner 677af4a1cb Bytecode format for LLVM 1.2 no longer explicitly encodes zeros in primitive

Chris Lattner e2f6317436 Allow bytecode files to refer directly to global values as constants, instead
