- Finally nailed: test/Regression/Assembler/2002-08-16-ConstExprInlined.llx
- ParseConstantPool was resolving reference to value using the function
slot # instead of the global slot #.
- Bytecode reader changes:
- Remove the failure<> template from Bytecode Reader
- Remove extraneous #includes
- s/method/function/ a bit
- Eliminate the fwdRefs class that just added abstraction where it was not
needed, making things more complex.
- Use a vector instead of a list for function signatures.
