* 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. :(
* Enable DoConstantPoolMerging to do trivial DCE of constant values.
* Fix DCE to work better, so that SCCP can show it's true value.
* 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:
if (I->isTerminator()) {
TerminatorInst *TI = (TerminatorInst*)I;
...
}
to be written as:
if (TerminatorInst *TI = I->castTerminatorInst()) {
...
}
* Think about whether edge split SSA form would be useful to do.
* Inlining should attempt to give block names the same name in the inlined
method (using SymbolTable::getUniqueName)
* The dropAllReferences code can be a noop when NDEBUG!!! * The dropAllReferences code can be a noop when NDEBUG!!!
