* 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:
|
|
* "packed format", like this: [4 x sbyte]: Packed SIMD datatype
|
|
* Bytecode reader should use extensions that may or may not be linked into the
|
|
application to read blocks. Thus an easy way to ignore symbol table info
|
|
would be to not link in that reader into the app.
