------- Comment #5 from rguenth at gcc dot gnu dot org 2010-07-01 11:35 -------
Confirmed. Works without -fuse-linker-plugin.
Reduced testcases:
wave.ii
-------
typedef unsigned int reg8;
typedef unsigned int reg12;
class WaveformGenerator {
public:
reg8 readOSC();
inline reg12 output();
reg8 waveform;
reg12 output____();
};
inline reg12 WaveformGenerator::output() {
switch (waveform) {
default:
return output____();
}
}
reg8 WaveformGenerator::readOSC() {
return output() >> 4;
}
sid.ii
------
typedef unsigned int reg8;
typedef unsigned int reg12;
typedef int sound_sample;
class WaveformGenerator {
public:
reg8 readOSC();
inline reg12 output();
reg8 waveform;
reg12 output____();
};
inline reg12 WaveformGenerator::output() {
switch (waveform) {
case 0x0:
return output____();
}
}
class Voice {
inline sound_sample output();
WaveformGenerator wave;
friend class SID;
};
inline sound_sample Voice::output() {
return wave.output();
};
class Filter {
public:
void clock(sound_sample voice1, sound_sample voice2, sound_sample voice3);
};
class SID {
void clock();
Voice voice[3];
Filter filter;
};
void SID::clock() {
filter.clock(voice[0].output(), voice[1].output(), voice[2].output());
}
