Bugs to fix:
|
|
- A few key hits ignored after leaving the application (could not reproduce)
|
|
- Lost keyboard control at startup (could not reproduce)
|
|
- Influence of keyboard on some timers and RTC (maybe interrupt priority)
|
|
- Alignment of ALL .data / .rodata files is required to ensure converted data
|
|
is properly aligned
|
|
|
|
Simple improvements:
|
|
- demo: Try 284x124 at (-60, -28) (all disadvantages)
|
|
- display: Rectangle-based drawing functions
|
|
- time: Compute CLOCKS_PER_SEC
|
|
- string: Use cmp/str to implement memchr() (assembler examples)
|
|
- string: Do some tests for memcmp()
|
|
- core: Register more interrupts (and understand their parameters)
|
|
- project: Clean headers that have some internal definitions
|
|
- project: Check size of all library structures
|
|
Larger improvements:
|
|
- errno: Introduce errno and use it more or less everywhere
|
|
- bopti: Monochrome bitmaps blending modes
|
|
- bopti: Handle partial transparency
|
|
- core: Implement all callbacks and a complete user API
|
|
* core: Better save registers
|
|
* core: Allow return to menu
|
|
- serial: Implement a driver
|
|
- usb: Implement a driver
|
|
- esper: Cleaner playback, synthetizing
|
|
- clock: Handle overclocking (relaunch clocks when overclocking)
|
|
- project: Unify this hellish mess of register access!
|
|
|
|
Things to investigate:
|
|
- Packed bit fields alignment
|
|
- Registers that may need to be saved within setjmp()
|
|
- Registers that may need to be saved and restored by gint
|
|
- Optimizing core/gint.c leads to raising of an illegal slot exception when
|
|
running the interrupt handler, although it ends on rte; lds.l @r15+, mach,
|
|
which is totally not an illegal slot.
|
|
- Check version registers on SH7705
