Keeping DEC Alpha support is difficult because there are no Alpha machines available for toolchain developers, and even if there were, no modern Linux distros still support Alpha. For example, Debian dropped Alpha support in Debian 6.0. As a result, I cannot test my linker with real-world programs. In fact, I believe mold has never been able to link real-world large programs. Object files for Alpha are compiled with the small code model by default, so it is not easy to support it in the linker. There's no means to verify that my implementation is correct for Alpha because Alpha's psABI has never been published by DEC. The most "reliable" source of correctness is GNU ld's source code and comments. Last but not least, I believe there are literally zero mold/Alpha users. Unlike some other retro computers like the m68k, Alpha doesn't seem to get much love from the community, perhaps because the availability of Alpha machines was limited in the first place, even in the 90s. Therefore, I'll remove Alpha support now. If there's someone who wants to keep it, we can resurrect and re-test it. This change should make the mold binary size a little smaller.
