A stop condition that can be checked during execution

Variants

Cycles(u128)

Stop after N master cycles

Frames(u64)

Stop after N frames

PcEquals(u16)

Stop when PC reaches address (breakpoint)

Opcode(u8)

Stop when opcode is executed

MemoryEquals

Stop when memory address equals value

Fields

addr: u16

value: u8

and: Option<Box<StopCondition>>

MemoryNotEquals

Stop when memory address does not equal value

Fields

addr: u16

value: u8

and: Option<Box<StopCondition>>

OnHalt

Stop on HLT instruction

Breakpoint(u16)

Breakpoint at address (alias for PcEquals, kept for backward compatibility)
