I tried to cross compile GCC with an alpha-linuxecoff target using Dan's
script but failed. I checked README of glibc2.2.5, it doesn't even claim
it support alpha-linuxecoff. As you said, maybe I have to use some
'custom' C library... things become difficult...

Having a separate toolchain for alpha-linuxecoff is definitely enough for
me, the thing is it may be difficult to get one. The reason I need ecoff
format is that I want to generate some binary to feed into a
cycle-accurate alpha simulator. The simulator was initiated a long time
ago, so it only accepts ecoff binaries. Maybe a cheaper way is to supply
an elf loader to the simulator. I will try to do that.

Thanks!
