The most recent version of gcc that I can get to compile on HPUX ia64 is 4.9.3. Even that required patching 4.7.4 (the last C-only gcc build) and using the patched 4.7.4 to build 4.9.3 (see bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64919). Plus a bunch of other minor changes during the build. The gcc-testresults mailing last has no hpux-ia64 targets listed at all. Is it worth filing bugs for build issues on this target? I get the feeling that no one is using this particular platform, but I'm certainly willing to help out with getting things fixed where possible. I just don't have the expertise to actually figure out what causes ICEs during the GCC build. Thanks!
