Too late for us, we're just finishing distro line based on gcc 3.3.x.
Anyway, gcc 3.4.0 build on alpha-linux crashes even earlier (just built ./xnmake
program catches SIGSEGV).
But back to topic...
this regression seems to be caused by this change:
http://savannah.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/config/alpha/alpha.h.diff?r1=1.213&r2=1.214
backported to 3.3.4 here:
http://savannah.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/config/alpha/alpha.h.diff?r1=1.185.4.4&r2=1.185.4.5
Despite description:
* alpha.h (HARD_REGNO_MODE_OK): Disallow SImode in FP regs.
it disallows not only SImode, but also e.g. SCmode, thus triggering ICE
(I tested that mode==21, i.e. SCmode just before this abort()).
