Watcom symbol dump codegen tools

codegen.py

Takes an exedump output file and generates skeleton "c" project files containing functions, structs, enums and global variables.

Was used to generate the first commits of src directory.

Example output:

typedef enum tPowerup_type {
    ePowerup_dummy = 0,
    ePowerup_instantaneous = 1,
    ePowerup_timed = 2,
    ePowerup_whole_race = 3
} tPowerup_type;

struct tPedestrian_action {
    float danger_level;
    float percentage_chance;
    int number_of_bearings;
    int number_of_sounds;
    int sounds[3];
    tBearing_sequence sequences[7];
    float initial_speed;
    float looping_speed;
    tU32 reaction_time;
};

// Offset: 9548
// Size: 1603
// EAX: c
void CalcEngineForce(tCar_spec *c, br_scalar dt) {
    br_scalar torque;
    br_scalar ts;
    br_scalar ts2;
    br_scalar brake_temp;
    int sign;
    tS32 temp_for_swap;
}

Usage

1. Concatenate the executable file and the symbol file

cat carma1.exe dethrace.sym > carma_with_symbols.exe

2. Execute wdump and pipe the output to file

wdump -Daglmt carma_with_symbols.exe > dump.txt

3. Execute the codegen tool

codegen.py dump.txt

You now have the C skeleton files in ./_generated.

split-dump.sh

Takes a exedump output file and splits it into a single file per module for easier debugging.
