------- Comment #5 from hutchinsonandy at aim dot com 2008-06-06 20:18 ------- Subject: Re: ICE push_reload - psuedo reg_equiv_constant
The patch for http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31786 removes one problematic part of LEGITIMIZE_RELOAD_ADDRESS. This is applied to WinAVR 20080512 (patched 4.3.0). But is still waiting for approval on avr-gcc 4.3/4.4 HEAD. Even with that patch, the other parts of L_R_A are bad and need fixing with added check of reg_equivalent_constant. So if register is equivalent constant LEGITIMIZE_RELOAD_ADDRESS should do nothing. The assert that triggers is an explicit check for this. I have not posted patch due to overlap with pending patch. BTW gcc list has short discussion on this bug, including explanation for the AVR code.
