Claude 08322abda4 Codegen: on_scanline per-state dispatch + NMI reload ... Extends the \`on_scanline\` codegen to support multiple scanline handlers across states: - \`__irq_user\` now dispatches by \`current_state\`: each state with a scanline handler gets a CMP/BNE/JSR entry in the dispatch table. States without a handler fall through to just acknowledge the IRQ. - New \`__ir_mmc3_reload\` helper that (re)loads the MMC3 counter latch based on \`current_state\`. States without a scanline handler fall through to disable the IRQ (\$E000 write). - Linker detects the \`__ir_mmc3_reload\` label in user code and splices a JSR into it at the top of the NMI handler, so the counter is reloaded once per frame with the current state's target scanline. - IRQ handler no longer re-enables IRQ on ACK (the NMI reload now handles that) so it won't fire multiple times per frame. - Program init chooses the start state's scanline count (if any) or the first scanline handler found as a fallback. Also fixes \`dump_asm\`: a \`NOP\` with a \`Label\` operand is a label definition, but any other opcode with a \`Label\` operand is a real instruction like \`JSR foo\`. The old dump was hiding JSR/JMP targets. https://claude.ai/code/session_01W6eQFStA66EuMKHUFo2rx3		2026-04-12 16:29:15 +00:00
