SDK v0.2.2

New platforms

• nes-nrom-128. Contains a simple PPU support library. Generates an iNES 2.0 file for the NES NROM-128 board.

New features

• llvm-objdump -d disassembler now shows branch targets using absolute addresses.
• __do_copy_data symbol reference emitted whenever .data section referenced.
• copy-data optional library to copy .data segment from ROM to RAM if necessary.
• exit-loop optional library to exit the program by entering an infinite loop.

Optimizations

• Placed C runtime constants in .rodata, not .data. Keeps them from being copied.
• Replaced runtime subtraction in .bss zeroing and .data copying with linker-computed size.

Bugfixes

• Added barrym95838's BCD behavior corrections to the 6502 simulator.

Refactors

• libstart renamed to libcrt0.
