* Change getConstantValue to throw an exception on error, not return nullChris Lattner2003-10-091-9/+3
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8988 91177308-0d34-0410-b5e6-96231b3b80d8
* Major refactoring of the bytecode reader. This includes the followingChris Lattner2003-10-091-22/+10
| | | | | | | | | | | | | | | | changes: * BytecodeReader::getType(...) used to return a null pointer on error. This was only checked about half the time. Now we convert it to throw an exception, and delete the half that checked for error. This was checked in before, but psmith crashed and lost the change :( * insertValue no longer returns -1 on error, so callers don't need to check for it. * Substantial rewrite of InstructionReader.cpp, to use more efficient, simpler, data structures. This provides another 5% speedup. This also makes the code much easier to read and understand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8984 91177308-0d34-0410-b5e6-96231b3b80d8

* * Cleaned up code:Misha Brukman2003-09-221-47/+48
| | | | | | | | | | - no more passing around a string pointer to set errors - no more returning booleans and checking for errors, we use C++ exceptions * Broke functionality into 2 new classes, one reads from file, one from a stream * Implemented lazy function streaming - the parser can read in a function at-a-time git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8671 91177308-0d34-0410-b5e6-96231b3b80d8

* * Bug fixes:Chris Lattner2003-03-191-13/+26
| | | | | | | | | | | | | | | | | | | | | | - Fix problems where the constant table would not get updated when resolving constants causes other constants to change. Changes to the V2 bytecode format - Null values are implicitly encoded instead of explicitly, this makes things more compact! - More compactly represent ConstantPointerRefs - Bytecode files are represented as: Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab instead of Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab which makes a lot of things simpler. Changes to the reader: - Function loading code is much simpler. We now no longer make function PlaceHolderHelper objects to be replaced with real functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5748 91177308-0d34-0410-b5e6-96231b3b80d8
