Reduced testcase:
extern "C" {
typedef __builtin_va_list __gnuc_va_list;
typedef __gnuc_va_list va_list;
}
typedef unsigned char uint8;
typedef unsigned int uint32;
typedef signed char int8;
namespace Audio {
class AudioStream {
};
}
class TownsPC98_FmSynth : public Audio::AudioStream {
};
class TownsAudio_PcmChannel;
class TownsAudioInterface : public TownsPC98_FmSynth {
int intf_pcmPlayEffect(va_list &args);
TownsAudio_PcmChannel *_pcmChan;
};
class TownsAudio_PcmChannel {
friend class TownsAudioInterface;
void loadExtData(uint8 *buffer, uint32 size);
int8 *extData;
};
class TownsAudio_WaveTable {
friend class TownsAudioInterface;
uint32 size;
};
int TownsAudioInterface::intf_pcmPlayEffect(va_list &args) {
int chan = __builtin_va_arg(args,int);
uint8 *data = __builtin_va_arg(args,uint8 *);
TownsAudio_WaveTable w;
TownsAudio_PcmChannel *p = &_pcmChan[chan];
p->loadExtData(data + 32, w.size);
}
void TownsAudio_PcmChannel::loadExtData(uint8 *buffer, uint32 size) {
int8 *src = (int8 *)buffer;
int8 *dst = extData;
for (uint32 i = 0; i < size; i++)
*dst++ = *src & 0x80 ? (*src++ & 0x7f) : -*src++;
}
Indeed makes it look like a dup.
