* Don't emit constant pool blocks for methods with empty constant pools!

* Need to implement getelementptr, load, and store for indirection through
|
||||
arrays and multidim arrays
|
||||
* BytecodeWriter should use a deque<unsigned char> instead of vector!!!
|
||||
* Eliminate the method signature from a call instruction. It should look like
|
||||
this: call int %func(int 2, int %reg118)
|
||||
* Indirect calls should use the icall instruction
|

* 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:

* fix the constprop br <x> <dst1> <dst1> case. Must handle PHI nodes correctly

* Fix DCE to work better, so that SCCP can show it's true value.

* Implement ADCE

* Fix the const pool printer to print out constants in some sort of "sorted"
|

order. Then enable TestOptimizer.sh to diff -sccp output. Currently it
|

doesn't work because the diff fails because of ordering of the constant

pool. :(

* Maybe ConstantPool objects should keep themselves sorted as things are

inserted.

* Enable DoConstantPoolMerging to do trivial DCE of constant values.

* Should provide "castTerminator, castPHI, etc" functions in Instruction, and

similar functions in other classes, that effectively do dynamic casts. This

would allow code like this:

dependance edges. Instead, the VM would just treat memory operations

* I need to have a way to prevent taking the address of a constant pool

reference. You should only be able to take the address of a variable.

Maybe taking the address of a constant copies it? What about virtual

function tables? Maybe a const pointer would be better...

function tables? Maybe a const pointer would be better... Alternatively,

we could alloca a local variable, copy a constant into it, and use that...
