Hello, I've been unable to bootstrap gcc 5.[12], starting from gcc 4.9.2, if I configure it with --with-abi=mx32 and having "ada" among the values for --enable-languages; searching the web I've found some old mailing list messages about ada not working on x32 (however gcc 4.9.x at least did complete the bootstrap under the same conditions). Is it still the case that ada isn't supported on x32 (and therefore I should drop ada from the language list for x32) or it's supposed to work instead (and therefore I can invest some more time finding out what I'm doing wrong)? Thanks, Giuseppe (In case it's of interest, what *I think* happens on my particular machine is that the stage2 gnat1 binary fails with EFAULT when ran during the bootstrap because it passes a wrong pointer to the write syscall; the pointer has in its lower 32 bits the correct address it's supposed to have, but other stuff in the upper bits. The stage1 binary, instead, is fine in this respect. Also, gcc 4.9.2 does bootstrap successfully on the same box with the same configure parameters. I don't know if this is due to a bug or rather a misconfiguration of my system.)
