| | | | | | | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15981 91177308-0d34-0410-b5e6-96231b3b80d8

* Various cleanups:Reid Spencer2004-07-111-153/+193
| | | | | | | | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14765 91177308-0d34-0410-b5e6-96231b3b80d8
* Error Handling Cleanup:Reid Spencer2004-07-091-121/+127
| | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14729 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14604 91177308-0d34-0410-b5e6-96231b3b80d8
* MAJOR REWRITE.Reid Spencer2004-06-291-326/+1355
| | | | | | | | | | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14494 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for reading bytecode files with compactiontables for bytecode files.Chris Lattner2004-01-181-30/+129
| | | | | | | | | This shrinks the bytecode file for 176.gcc by about 200K (10%), and 254.gap by about 167K, a 25% reduction.

This saves a fairly substantial chunk of bytecode space.
