- va_arg nodes
|
|
? BSTART, BEND nodes (to free data allocated by ALLOCA) (now it's possible to do this through AFREE)
|
|
- Full support for function prototypes ???
|
|
(now we may only set "fastcall" calling convention for constants or for variables through BITCAST)
|
|
|
|
- VLOAD, VSTORE -> SSA
|
|
|
|
? reassociation folding rules
|
|
- folding engine improvement (one rule for few patterns)
|
|
|
|
- irreducable loops detection/support
|
|
|
|
- Extend SCCP to support range inference and PI node
|
|
|
|
? instruction selection
|
|
- xor, btsl=INCL, btrl=EXCL, btl=IN, bsr
|
|
- MOVZX to avoid a SHIFT and AND instruction
|
|
- BURS ???
|
|
|
|
? register allocation
|
|
- hints and low priority registers (prevent allocating registers that are used as hints

|
|
- optimisation of spill code placement (BB local or through resolution)
|
|
- separate INT and FP allocation phases (for performance)
|
|
- respect multi-ENTRY code (Zend/tests/bug72598.phpt)
|
|
- proper live ranges for complex codegen rules (Zend/tests/match/042.phpt [jit=1254/ZTS/32])
|
|
|
|
? code generation
|
|
- COND
|
|
- TAILCALL with stack arguments (tests/x86/tailcall_001.itr)
|
|
- 32-bit x86 back-end 64-bit integers support
|
|
(add_009.irt, conv_001.irt, conv_002.irt, conv_004.irt, conv_010.irt, sub_009.irt)
|
|
- binary code emission without DynAsm ???
|
|
|
|
- modules (functions, data objecs, import, export, prototypes, forward declarations, memory segments, ref data, expr data)
|
|
- C front-end
