* Rewrite the llvm parser/lexer in http://www.antlr.org when time permits.
They actually do C++. Imagine that.
-* Fix DCE to elminate br <c>, %L1, %L1 so that it can optimize the main of
- fib.ll better. Currently I have to do this to get best results:
- as < fib.ll | opt -inline -sccp -dce -sccp -dce |dis
-* fix the constprop br <x> <dst1> <dst1> case. Must handle PHI nodes correctly
-* Think about whether edge split SSA form would be useful to do.
-* The dropAllReferences code can be a noop when NDEBUG!!!
-* pred/succ iterators on basic blocks don't handle switch statements correctly
-* Provide a pass that eliminates critical edges from the CFG
* Need a way to attach bytecode block info at various levels of asm code.
* Recognize and save comments in assembly and bytecode format
* Encode line number table in bytecode (like #line), optional table
* Encode negative relative offsets in the bytecode file
-* Implement switch to switch on a constant pool array of type:
- [{ label, int }] or [label] (lookup vs index switch)
* Apparently bison has a %pure_parser option. Maybe useful for AsmParser
* Implement the following derived types:
