* Change all of the bytecode reader primitives to throw exceptions instead ofChris Lattner2004-01-151-14/+6
| | | | | | | | | | returning error codes. Because they don't return an error code, they can return the value read, which simplifies the code and makes the reader more efficient (yaay!). Also eliminate the special case code for little endian machines. llvm-svn: 10871

* Major refactoring of the bytecode reader. This includes the followingChris Lattner2003-10-091-242/+140
| | | | | | | | | | | | | | | 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. llvm-svn: 8984
* Significantly clean up parsing of instructions. This exceptionizes andChris Lattner2003-10-091-138/+103
| | | | | | | simplifies the control flow a bit. This provides a small (~3%) speedup, but it's primarily a cleanup exercise. llvm-svn: 8983
* This patch substantially simplifies and cleans up handling of basic blocksChris Lattner2003-10-081-20/+17
| | | | | | | | | | | | | in the bytecode parser. Before we tried to shoehorn basic blocks into the "getValue" code path with other types of values. For a variety of reasons this was a bad idea, so this patch separates it out into its own data structure. This simplifies the code, makes it fit in 80 columns, and is also much faster. In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds up bytecode parsing from taking 6.9s to taking 2.32s. More speedups to follow later. llvm-svn: 8977
* Various cleanups and simplifications. This speeds up reading a bytecode fileChris Lattner2003-10-081-18/+18
