Detailed Description

Internal representation of a function.

Field Documentation

int builtin

if non 0, call an internal function

int code

first statement

struct def_s* def

output def holding function number

int function_num

struct set_s* global_vars

set indicating which vars are global

struct flowgraph_s* graph

the function's flow graph

int line_info

int local_defs

const char* name

nice name for PRETTY_FUNCTION

struct function_s* next

int num_statements

int num_vars

total number of variables referenced

struct reloc_s* refs

relocation targets for this function

string_t s_file

source file with definition

string_t s_name

name of function in output

struct sblock_s* sblock

initial node of function's code

struct statement_s** statements

struct symbol_s* sym

internal symbol for this function

struct symtab_s* symtab

Root scope symbol table of the function.

Sub-scope symbol tables are not directly accessible, but all defs created in the function's local data space are recorded in the root scope symbol table's defspace.

struct def_s* temp_defs[4]

freed temp vars (by size)

int temp_num

number for next temp var

struct expr_s* var_init

struct flowvar_s** vars

Array of pointers to all variables referenced by the function's code.

This permits ready mapping of (function specific) variable number to variable in the flow analyzer.
