WebSimilar to control transfer to a normal function, a control transfer to an interrupt or exception handler uses the stack to store the information needed for returning to the interrupted code. As can be seen in the figure below, an interrupt pushes the EFLAGS register before saving the address of the interrupted instruction. WebControl Instructions Unconditional jump and link (UJ-type) opcode = JAL: rd pc + 4; pc pc + J-imm J-imm = signExtend({inst[31], inst[19:12], inst[20], inst[30:21], 1’b0}) Jump ±1MB range Unconditional jump via register and link (I-type) opcode = JALR: rd pc + 4; pc (rs1 + I-imm) & ~0x01 I-imm = signExtend(inst[31:20])

Web§Control instructions set the PC to a new value during the Execute phase, so the next instruction comes from a different place in the program. §This allows us to build control structures such as loops and branches. 3 4 Instruction Cycle •Six phases of the complete Instruction Cycle oFetch: load IR with instruction from memory WebTo enable the 'E' operation code extender handler, you specify an 'E' (or 'e') with any of the operation codes that support it, for example, CHAIN(E). Coding the 'E' extender affects the value returned by the built-in functions %ERROR and %STATUS for exceptions. ... control returns to the next sequential instruction following the EXSR operation ... bird bath urn for ashes

You can double click it and it’ll take you straight to the function. Magic. You’ll also find out very quickly that the IDA API is garbage to work with because the docs are shit and reverse engineering is witchcraft. dalle 2 terms of service
