1 * grep '[A-Za-z][A-Za-z]*\*)' `./getsrcs.sh ` | & less
4 * Need to implement getelementptr, load, and store for indirection through
5 arrays and multidim arrays
6 * Rewrite the llvm parser/lexer in http://www.antlr.org when time permits.
7 They actually do C++. Imagine that.
8 * Fix DCE to elminate br <c>, %L1, %L1 so that it can optimize the main of
9 fib.ll better. Currently I have to do this to get best results:
10 as < fib.ll | opt -inline -sccp -dce -sccp -dce |dis
11 * fix the constprop br <x> <dst1> <dst1> case. Must handle PHI nodes correctly
12 * Fix DCE to work better, so that SCCP can show it's true value.
14 * Fix the const pool printer to print out constants in some sort of "sorted"
15 order. Then enable TestOptimizer.sh to diff -sccp output. Currently it
16 doesn't work because the diff fails because of ordering of the constant
18 * Think about whether edge split SSA form would be useful to do.
19 * Inlining should attempt to give block names the same name in the inlined
20 method (using SymbolTable::getUniqueName)
21 * The dropAllReferences code can be a noop when NDEBUG!!!
23 * pred/succ iterators on basic blocks don't handle switch statements correctly
24 * Provide a pass that eliminates critical edges from the CFG
25 * I need to provide an option to the bytecode loader to ignore memory
26 dependance edges. Instead, the VM would just treat memory operations
27 (load, store, getfield, putfield, call) as pinned instructions.
28 * Need a way to attach bytecode block info at various levels of asm code.
29 * Recognize and save comments in assembly and bytecode format
30 * Encode line number table in bytecode (like #line), optional table
32 * Encode negative relative offsets in the bytecode file
34 * Implement switch to switch on a constant pool array of type:
35 [{ label, int }] or [label] (lookup vs index switch)
36 * Apparently bison has a %pure_parser option. Maybe useful for Assembly/Parser
38 * Implement a header file that can read either assembly or bytecode, implement
39 a writer that can output either based on what is read with this reader..
40 * Implement the following derived types:
41 * "packed format", like this: [4 x sbyte]: Packed SIMD datatype
42 * Maybe 'tailcall' also?
43 * Include a method level bytecode block that defines a mapping between values
44 and registers that defines a minimally register allocated code. This can
45 make me finally address how to encode extensions in assembly.
46 * Bytecode reader should use extensions that may or may not be linked into the
47 application to read blocks. Thus an easy way to ignore symbol table info
48 would be to not link in that reader into the app.
