Member Data Documentation

flags

uint32 switch_info_t::flags

Switch info flags

ncases

ushort switch_info_t::ncases = 0

number of cases (excluding default)

jumps

ea_t switch_info_t::jumps = BADADDR

jump table start address

values

ea_t switch_info_t::values

values table address (if #SWI_SPARSE is set)

lowcase

uval_t switch_info_t::lowcase

the lowest value in cases

[union]

union { ... } switch_info_t

defjump

ea_t switch_info_t::defjump = BADADDR

default jump address (#BADADDR if no default case)

startea

ea_t switch_info_t::startea = BADADDR

start of the switch idiom

jcases

int switch_info_t::jcases = 0

number of entries in the jump table (SWI_INDIRECT)

ind_lowcase

sval_t switch_info_t::ind_lowcase = 0

elbase

ea_t switch_info_t::elbase = 0

element base

regnum

int switch_info_t::regnum = -1

the switch expression as a value of the REGNUM register before the instruction at EXPR_EA.

-1 means 'unknown'

regdtype

op_dtype_t switch_info_t::regdtype = 0

size of the switch expression register as dtype

custom

uval_t switch_info_t::custom = 0

expr_ea

ea_t switch_info_t::expr_ea = BADADDR

If BADADDR, then the first insn marked as IM_SWITCH after STARTEA is used.

marks

eavec_t switch_info_t::marks

the insns marked as IM_SWITCH. They are used to delete the switch.
