¹ C6808 "C" COMPILER 3.0.0.17 - Current evaluation version as of 2012-5-12
² C Compiler for M68HC08 (COSMIC Software); Generator V4.6.3 - 05 Aug 2008; Optimizer V4.5.9 - 05 Aug 2008 - Current evaluation version as of 2012-5-12
³ ANSI-C/cC++ Compiler for HC08 V-5.0.39 Build 11346, Dec 13 2011 - Current evaluation version as of 2012-5-12
This is a list of feature requests, that combined will probably get code size down near to the level of the non-free compilers.
| Request ID | Summary |
|---|---|
| 3526527 | Pointer analysis |
| 3526526 | Generalized constant propagation |
| 3526292 | Direct assignment / clear |
| 3526285 | Non-destructive and for ifx (hc08) |
| 3526278 | Multibyte constant assignment |
| 3526274 | Tail call optimization |
| 3526270 | Eliminate untargeted labels |
| 3526269 | Right operand for setting value at address |
| 3526268 | Right operand for GET_VALUE_AT_ADDRESS |
| 3525464 | lospre |
| 3528282 | notUsed() |
